Abstract
Fresh water fish consumption in West Java Indonesia is high. There are two popular fresh
water fish in Wst Java community namely Nila Tilapia or Oreocromis niloticus and carp orCyprinus carpio. Most of the fresh water fish for West Java consumption was supplied by
Saguling and Cirata reservoir fisheries. According to water quality monitoring, it was revealthat water quality in Cirata and Saguling were categorized Poor based on water standard Class
I of Government Decree No. 82 Year 2001. Parameter that tends to be increased is heavy
metal such as copper and lead. Fish has capability to uptake and depurate copper and leadfrom water which depend on the concentration and time of exposure. This study was aimed toinvestigate depuration time of copper and lead in Nile tilapia or Oreochromis niloticus.
Uptake process was conducted in laboratory and followed by depuration process. Copper andLead concentrations that used in uptake process were based on water quality standard andhigher concentration in reservoir water quality monitoring. Copper and lead concentration infish was calculated every 7 days during uptake process until 28 days and every day indepuration process for three days. For depuration process, additional samples of fish from
Cirata and Saguling reservoir also analysed. According to the result, depuration process could
not always decrease the Cu concentration because it was depend on several factors such as Cu
concentration in the organ target, time of depuration, and the abnormalities of organ after
accumulation process. Therefore Cu depuration need time more than three days. On the other
hand lead concentration in depuration process decreased significantly in three days.
Keywords: Oreochromis niloticus, depuration, copper, lead
Introduction
Indonesian people love to eat a fresh water fish for their daily consumption. In West Java, themost popular fresh water fish are Nila Tilapia or Oreocromis niloticus and carp or Cyprinus
carpio. These species were cultivated in several type of aquaculture such as privateaquaculture or the reservoir. There are three reservoirs in West Java namely, Saguling, Cirata,
and Jatiluhur. Most of the fresh water fish for West Java consumption was supplied by
Saguling and Cirata reservoir fisheries (Oktaviatun, 2004). Previously these reservoirs werebuilt as hydroelectric power supply, but later on they were used as tourism and fishery
activities. Local community whose area was drowned by the built reservoirs allowed using
the reservoir as aquaculture farming as compensation. As results, in these reservoirs many
floating caged-fish aquaculture are occupied. This activity has change water quality of
Saguling and Cirata reservoirs. In addition, these reservoirs also receive water from Citarum
River which has polluted by industrial, domestic and agriculture activities.

-1-According to water quality monitoring it was reveal that the quality of water in Saguling andCirata reservoirs were categorized Poor based on water standard Class I of Government
Decree No. 82 Year 2001. Parameters that tend to be higher are heavy metal such as copperand lead. In 2004, concentration of copper and lead were still below the standard but it wasincreased every year. According to Kompas Newspaper (2008), copper concentration reach
0.04 and 0.11 mg/L in several sampling point of Cirata reservoir, this concentration above thestandard which should be below 0.02 mg/L. On the other hand, Lead concentration alsoreached permission limit which is 0.03 mg/L.
Fish has capability to uptake Cu and Lead from the water and bioaccumulated. This processdepends on several factors such as the concentrations and time of exposure. Cu and lead arelipophilic so can be easily bound in fatty tissue of fish even though fish has capacity todepurate (transfer or remove) the metal to surrounding environment (water) (EPA, 1996).
Capability to accumulate the metal, especially Cu and Lead, has potential risk to upper tropic
level such as human. Higher Cu accumulation could affect human health such as inhomeostatic control (Harris, 1991). While lead accumulation could effect gastric and willaccumulate in bone for 30-40 years (US EPA: 2004, Darmono: 1995)
The aims of study are to investigate time of depuration of copper and lead concentration fromthe most dominant fish in Saguling and Cirata reservoir. Fisherman in Saguling and Cirata
reservoirs grow Nila Tilapia or Oreocromis niloticus and carp or Cyprinus carpio. The
research was conducted in several studies. The first study investigate lead and copper
depuration in laboratory while the second study investigate lead depuration process in Cirata
and Saguling fish. The results would be use as recommendation for community and further
studies.
Material and Methods
The research was conducted in laboratory and consists of two step, firstly, metal uptake
process than continue with the depuration process. O. niloticus were obtained from Ciherangfish hatchery both male and female at 4-5 weeks. Acclimatization was conducted for 15 daysand 28 days for uptake process. For copper depuration studies, the fish were divided into
three groups, one group for control and two groups for treatment (duplo). Each group wasplaced into flow-trough tank with flow rate 60ml/min. Stock solution was made using
CuSO4.5H2O (SMEWW, 2001) and dechlorinated watertap for the dilution water. Cu
concentration observed were 0.002;0.02; and 0.04 mg/L. In the other hand, lead depuration
process used semi static tank and stock solution was made using Pb(NO3)2 (US EPA, 2001).
Pb concentration observed were 0.03 mg/L and 1 mg/L according to Government Regulation
No. 82/2001 for water quality standard.
The studies also conducted in field scale using O. niloticus from the Saguling and Cirata
reservoirs. The fish that ready to harvest (3-4 month) were collected and move in to aquarium
supplied with aerated dechlorinated tapwater from PDAM, Bandung. There were to different
volume of water that was used in depuration process, 9 liters and 18 liters of water. Leadconcentration of fish in depuration process was observed in day 0 and day 3.
Indonesia National Standard (SNI) 01-2362-1991 and 01-2368-1991 were used to analyse Cu
and Pb concentration in fish and water samples. Wet and dry weight of fish sample was-2-calculated, using 2-3 grams of fish sample (dry weight) which was destructed using H2NO3 pa,
added with H2O2 and aquadest until 25 ml of volume. All sample was analyzed by AAS andcalculated to obtain copper and lead concentration in fish.
Results and Discussion
Cu concentration in fish can be show in Fig.1. For Cu concentration of 0.002 mg/L, Cu uptake
into total body concentration was increased at day-7, declined at day-14 and raised again inday-21 and 28. Different pattern was found at 0.02 mg/L and 0.04 mg/L Cu concentration
which total body concentration rose at day-14 and 21 and declined at day 21 and 28. Even
though Cu concentration in total body fluctuated every week for each concentration oftreatment, at the end of process (day-28) Cu concentration was increased from day-0 during
accumulation process. The concentration of Cu uptake followed an order as : 0.04 mg/L >0.02 mg/L > 0.002 mg/L.

Figure 1. Uptake and Depuration of copper in fish with different copper concentration inwater
In depuration process, 0.002 and 0.04 mg/L treatment have similar pattern. Concentration ofcopper in fish in first day significantly decreased but increased in second day and finallydecreased for 0.002 mg/L treatment and increased for 0.04 mg/L. Generally copper
concentration in fish in 0.002 and 0.04 mg/L treatment decreased on day-3. On the other hand,
0.02 mg/L treatment had fluctuated pattern, copper concentration on day-3 higher than copper
concentration on day-0
Fluctuated of Cu concentration in fish during depuration process interfered by several factors.
Cu concentration measured was the total concentration which consist of Cu concentrationeach target organ. Kristijarti (2006) state that Cu concentration in liver and gill during
depuration process (day-1 and day-3) still high, but in the muscle was relatively stable.
Arellano et al (2000) conducted his research exposed Solea senegalensis and Halobatracus
didactylus with Cu 100μg Cu+/L on the organ target and the results showed that there wasdecrease in copper levels in liver on day-2 and 4 and day-4 in gill during depuration process,-3-

but in the muscle there was no significant differences between accumulation and depuration
process.
The other factors that influenced depuration process were detoxification of Cu by liver andgill that plays role in detoxifications as well as storage (Kotze et all, 1999). This organ could
be dysfunction because of internal Cu concentration exceeded the capacity and capability of
the liver and gill to detoxicate the metal. According to Kristijarti (2006) there wereabnormalities of organ tissue especially in liver and gill tissue at the end of accumulation
process. Depuration process cannot always decrease and recover this abnormality. Thiscondition also found in Cerqueira dan Fernandes (2002) research, which investigated thechanged in Prochilodus schofa (tropical fish) gill tissue and in blood responses after 96-h Cu
exposure and transfer to clean water. Restoration of gill structure was slow, with no tissue
improvements in the first 2 days in clean water from the 7th to the 15th days. The recovery ofgill tissue began to become evident, with complete recovery occurring on the 45th day in cleanwater.
Uptake process for lead in fish show different pattern than copper uptake (Fig.2). Lead uptake
in 1 mg/L significantly increased every 7 days until 28 days while in 0.03 mg/L treatment
lead concentration in fish increased slowly. In depuration process, lead concentration was
significantly decreased in both treatments on day-1 and slowly decreased until day-3. Leadconcentration in depuration process on day-3 was decrease more than 90% for 0.03 mg/L
treatment and 86% for 1 mg/L treatment.

Figure 2. Uptake and Depuration of lead in fish with different lead concentration in water.
Fish from Saguling and Cirata was taken as a sample for uptake process. Lead concentrationin Saguling fish was higher than Cirata Fish because Saguling reservoir water quality waspoorer than water quality in Cirata reservoir. Depuration process was conducted in laboratory
using un-chlorinated tap water. Lead concentration in fish during depuration process can beshowed in Fig.3. Lead concentrations in fish were slowly decreased during depuration process-4-in 9 liters tank for both Saguling and Cirata reservoir. In the contrary, lead concentration infish at 18 L tank tend to increased on day-1 and significantly decreased on day-2 andunmeasured in day-3.

Figure 3. Lead Depuration in Saguling and Cirata fish.
Both studies showed that Copper and Lead has different mechanism in uptake and depuration
process for O. niloticus. Copper concentration in fish tends to has fluctuated pattern duringuptake and depuration process with different concentration of treatment. On the other handlead has typical pattern in different treatment. In depuration process day-3, copper
concentration still high and the efficiency of depuration below 50% while lead depuration has
higher efficiency (above 80%). As mention before, depuration process for Cu depend on
several conditions such as Cu concentration in the organ target, time of depuration, and theabnormalities of organ (liver and gills) after accumulation process. The studies also showedthat copper need longer time than lead in depuration process. Therefore, community should
keep the fish more than 3 days in unpolluted water to reduce copper concentration in fish
before they consume it while time to reduce lead concentration in fish 3 days would be
effective.
However, even though fish has capacity to depurate copper and lead by replace it to theunpolluted water, further research should be conducted especially in field scale and find out
water parameters such as pH, hardness, combination pH-hardness or other combination ofparameter that could effectively reduce Cu concentration in fish during depuration process
Conclusion
Copper and lead has different mechanism in uptake and depuration process. Copper
concentration in fish tends to has fluctuated pattern while lead has typical pattern in different
concentration of treatment.

several condition such as Cu concentration in the organ target, time of depuration, and theabnormalities of organ after accumulation process. Therefore Cu depuration need time morethan three days.
Depuration process can significantly decrease the Pb concentration in fish in three days forboth in laboratory studies and Sastudies (laboratory and field)

Abstract
Globally, due to competition for economic development, the per capita demand for natural
resources is increasing. This requires community participation for resources conservation,
based on a value system that they understand and appreciate. In this context, an initiative
taken by Divya Jyoti Jagrati Sansthan (DJJS), New Delhi is presented here, with aim togenerate public awareness and induce community participation, especially of women andyouth, in Sheri Kanda, Pithoragarh District, Uttarakhand. Door to door survey for collectionof information, Community Awareness Campaign, Pre-Training Session, Training of Trainers,
and Pilot Level Technical Survey were undertaken. Pre- and Post- initiative situation analysis
was done. A drastic change was seen in the attitude of the people especially women withgrowing participation and cooperation. The Community showed growing awareness of thewater related issues and willingness to implement rainwater harvesting. The initiative
provided strength in a wide range of areas, through community mobilisation and women's
empowerment, promotion of education and culture, community health management byimprovement in water and sanitation aspects.
Keywords: Community participation, rehabilitation, ecosystem, mountainous area, India.
Introduction
In India, the Himalayan Mountain region has a large number of ethnic societies having theirown social, economic and cultural attributes, and thus, presents a unique socio-ecologicalrichness with traditional knowledge and experience, and forms a powerful link between thenature and the social systems. Due to competition among the local communities for earning
their livelihood, the per capita demand for natural resources especially water is increasing.
Hence, any nature conservation linked initiative has to be based upon a value system that they
understand, appreciate, and feel interested to participate. However, the task of development
and management of human resource, water, land, soil, crop, livestock, pasture, etc. requires
great care, seeking community participation at each step. Therefore, an analysis of the socioecological systems with watershed concept, integrating technical, physical and social
dimensions in a synchronized manner, can be helpful for resources management, and canprovide long-lasting replicable solutions to the problems of socio-ecological rehabilitation.
But, generally it is observed that the biophysical dimensions are better understood than issuesof socioeconomics, community participation, people’s empowerment, institution building, andequity and gender considerations.
In this context, Divya Jyoti Jagrati Sansthan (DJJS), New Delhi took an initiative during MayOctober, 2007 for socio-ecological transformation to tackle the problem of water scarcity, andgenerate public awareness, community participation and capacity building, especially of-7-women and youth, in Sheri Kanda (Long.: 80°09.766’E, Lat.: 29°31.120’N, altitude 1721
amsl), at a distance of 17 km southwest of Pithoragarh (29.58° N 80.22° E; altitude 1650m
amsl). The area is underdeveloped and naturally landscaped in an undulated rocky andrubbled terrain on a tubular ridge of slates, limestones and greenstone, surrounded with snow
capped mountains, valleys, forests, perennial rivers, springs and waterfalls. Water sources arelocated about 1.5 km down hill. Annual average rainfall is 36.7 cm, of which 80% occurs
during the monsoon period June to September and 20% during winter (December–March). In
December- January, mountain ridges receive snowfall and have 5.5°-8°C temperature. Floraand fauna has rich ecological diversity. Chir forests occur at 500-1800m altitudes and Sal
forests up to 1,220 m.
Initiatives for community participation
A meeting was held with the villagers in May, 2007 to consider the following activities, andrepresentative members were selected for workshop on Training of the Trainers (TOT):
1. Physical: Ninety seven households in the village and nearby hamlets were surveyed
with questionnaire and baseline information on socioeconomic structure, educationwater resources in and around the hamlets and water usage was collected, to get a
picture of the prevailing water problem. Assessed the knowledge and awareness levelof local people.
2. Outreach: Each and every household was reached door-to-door and was given the
introduction of the programme through community meetings. Well-planned pretraining communication programs were undertaken to plan the training to reach thepeople.
The key issues of concern and the causal factors were: (a) Under developed Area, (b)Environmental ignorance, (c) Improper management of natural resources, (d) Absence ofPucca road and mode of transport, (e) Water Scarcity, (f) Inadequate facilities for health,sanitation and hygiene, (g) Alcoholism and drug abuse, (h) Vulnerability and drudgery of
Women, (i) Poor economic condition (j) Lack of education, (k) Unemployment, and (l) Forest
fire. The impact of the first meeting on the villagers was significant and they showed interest
to participate in the scientific campaign, accompanying the survey team door to door forcollection of data.
(A) Pre-Training Session: The session was held in July, 2007, with participation of fourteen
persons including four DJJS volunteers and two women. A Focused Group Discussion was
also organised, where the representatives from Sainio Ka Sangathan (SKS), a localorganisation in the Uttrakhand working on environment and community welfare issues, and
the Project facilitator explained the villagers about the incentives of training and knowledge,
which included: (1) importance and benefits of the training, and (2) the responsibilities andwork of trainers. Their work after the training included: Community mobilization, consensus
building, promoting coordination, awareness generation, and assisting the execution of the
programme. Focused Group Discussions, Community Meetings, and Women Group Meetings
proved most effective in reaching the people, understanding them, explaining them theprogramme concept, motivating them for participation and taking their inputs for planningand executing activities.

(B) Training of the Trainers: The workshop, facilitated by SKS, was held in July, 2007, to
impart training to the volunteers on the concepts of watershed management and collective
action, through lectures, demonstrations, questionnaires and field site visits. Fourteen persons
were trained, and this group and DJJS volunteers led all the training and awareness programs,
and also carried out door to door household and general survey with the questionnaire.
Workshop included the following activities, to equip the trainees with information on various
concerns:
Activity–1 Theoretical/ system training about the Watershed Concept: General
information were provided through lectures, diagrams, maps, charts, etc. on various
biophysical features of watershed and hydrological cycle; the existing water resources andreserves, plantation and vegetation, importance of soil and water conservation; socioeconomic aspects, major problems and unmet needs; economic livelihood, needs to manage awatershed efficiently, insight to alternate scenarios of income generation and watershedmanagement, etc.
Activity–2 Planning for minor Watershed Management: Training was imparted on PRA,
watershed management procedures, creation of advisory committees for awareness generation,
management and regeneration of forest, other land, natural resources, and control of forest
fires.
Activity–3 Collective Protection and Maintenance: Insight was given into how to plan andimplement different collective action and strategies for maintenance and conservation ofnatural resources, particularly water, by creation of institutional setups like ‘Pani Panchayats’
that can serve as tool of decentralization, devolving power and responsibility onto thecommunity.
Activity–4 Role of communication in village perspective for scientific practises: Thetrainees were taught effective ways of communication to awaken and sensitize the local
community to the issues of water management, sanitation and hygiene, land and forest
conservation etc.
Activity – 5 Development of future perspective for: Preparation and implementation ofawareness campaign. The various aspects dealt under this activity were development ofsurvey formats; need assessment and need based planning as well as methods of planning.
(C) Community Awareness Implementation Programme:(a) Preparatory Phase: The following activities were planned and works assigned in teams:
1. Visit to forest area to collect information on resource infrastructure, water sources,
their numbers, capacity and distance from village and rainfall by direct
measurement.
2. Develop communication material: (i) Making Puppets for thematic show, (ii)
Writing scripts and songs for play/skits, and (iii) Making slogans, posters, etc.
3. Develop Communication teams involving villagers to (i) interact with thecommunity; (ii) talk to women specially, and (iii) prepare puppet shows, dramaand skits.
4. Prepare presentations on: (i) History and future of water; (ii) Water cycle; relation
among water, forest and soil, (iii) Health, water and over all wellbeing, (iv)
Biodiversity and community, (v) Adverse impacts if issues are not addressed in
time.

Supervision meetings were also held to take feedback on (i) work completed by teams, (ii)
activities which could not be carried out, problems faced and finding solution to the problems.
Subsequently, the following activities were undertaken:
1. Community meetings were conducted and a well-structured plan for the community
awareness programme was formulated by fourteen trainees, resource persons, along with
Project Facilitator, wherein people expressed their problems and volunteered to cooperate.
The community provided important inputs in deciding the timings and scheduling of activities
in a manner when villagers would be free from fields and can participate. A Women Groupwas formed.
2. Internal community meetings were organised by the trainees of TOT to appraise thecommunity members regarding existing problems and possible solutions. Villagers wereencouraged to participate in programme. Communication teams were formed.
3. The trainees visited door-to-door and counselled people on water, health sanitation andeducation issues. They were told the importance of community participation in solving the
problems, through banners, posters, slogans, etc.
4. The formats containing questions on basic information on number of family members,
agriculture, irrigation, health and hygiene, and water conservation were designed to assess thesocial and economic conditions and awareness level in the community. The trainees
distributed the survey formats through different groups, and filled these forms.
5. Plays, skits, songs, puppet shows, speeches, etc. were organised.
(b) Execution Phase:
I. Public Mobilization: A three days awareness generation camp was held in Sep, 2007.
Various communication instruments like posters, skits, speeches, plays; puppet shows etc.
were used, to sensitize people towards the issues on water sanitation, health and hygiene,
water borne diseases and its prevention. The villagers also presented plays and skits on
relationship between water, soil and forest, how to save water, different problems faced indaily lives, social evils like growing drug addiction, its socio-economic impacts, etc., showing
their increased participation. Speeches were conducted on issues like agriculture, dairy
farming, importance and conservation of water resources, etc. Other activities included: (a)Formation of a youth group; (b) Formation of Pani Panchayat, and (c) Planning of technicaldemonstration.
II. Technical Demonstrations included (1) Developing Poly Tanks and collection of rainwater; (2) Recharge Pits to maintain water level in water sources; (3) Cleaning & maintenanceof existing water sources; and (4) Creation of culverts at upper reaches of the hills for
temporary storage of water and thus promoting ground water recharge.
(D) Pilot Level Technical Survey: The survey was made in October, 2007 covering 25 km2
area at 1568-1832m altitudes by non-stop 15 km trekking on steep slopes up and down thehills, with GPS measurements on longitude, latitude and altitude. GIS was used to integrate,visualise and manage the data, with the aim to survey the natural drainage system, for
identifying the possible locations of high flow water channels, and water harvesting. The teamworked closely with local communities, using participatory methods, and made efforts ofintroducing new technologies to suit different locales and needs. Seven spots were located for
exploring the possibilities of soil-water conservation: Nanda Dhara (Altitute: 1568m, Long.:
80°09.749’E, Lat.: 29°31.245’N); Kanda (Alt.: 1721m); Kanda School (Long.: 80°09.766’E,
Lat.: 29°31.120’N, Alt.: 1690m); Sheri Kanda (Alt.: 1720m); Bhamkanigar (Alt.: 1738m);
Vinayak (Alt.: 1832m; Long.: 80°10.201’E, Lat.: 29°30.657’N); and Latkhola Moruadha-10-

(Alt.: 1673m). Samples were collected for determination of water quality, soil structure andwater holding capacity; and locating fields for soil/water management.
The survey indicated that the cultivated lands have 3-6% topographical slopes. The soils areneutral to alkaline, mostly calcarious, dark in colour, gravel or single grained and highly
vulnerable to erosion. Soil structure is non-spherical sub-rounded; spherical sub-rounded; andspherical angular. Soils water holding capacities are 34.7-61.93%. Soils Organic Carbon
contents range from 0.001% to 1.9%. The flora is beautifully distributed and most plants havesome medicinal value. Natural vegetations are Buj, Chir, Tuni, Timal, Malta, Santra, Anar,
Burash, Aru, Naspati, Ritha, etc. Farmers grow Wheat, Rice, Urd, Masoor, Makka, Arbi,
Haldi, Khira, Adrak, Potato, Rajma, Soybean, Tori, Brinjal, Tomato, Cabbage, Chilli, etc.
Farmers use traditional/wild seeds for vegetables and food grains, and use conservation
measure like growing crops in the lower slopes.

Questionnaire survey based situation analysis
Status Indicators - Socio-economic status: Almost 90% of villagers stay in ‘pucca’ houses.
A family generally has 5-7 members, with average monthly income Rs. 500-7000/-. Around
72% households depend on subsistence oriented underdeveloped small scale rain-fed
agriculture on 61ha area, characterised by low productivity. People generally spend 4-6 hours
in agriculture. Unawareness about scientific and modern methods, conventional method of
agriculture, and no irrigation facilities gives poor yield. Women are the major workers both infields and household chores. Men opt for uncertain labour jobs, with disguised and seasonal
unemployment. Few people who join Army take Voluntary Retirement to get pensions, which
are used in paying back the debts, or in unplanned economic activates like opening up shops,
putting up taxis etc. Water scarcity does not permit promising interventions like dairy farming,
herbal gardening, organic farming, etc. Animal droppings are used along with leaves andgrasses, and stored in livestock sheds for soil organic manure. 85% households use wood fueland 36% have LPG but use rarely.
There is an acute water shortage, which becomes severe during summer. Average waterrequirement per family is 10-200 lpd, depending on the family size and number of animals
owned, while available water is 40-120 lpd, depending on number of trips taken to fetch water.
On an average 1-4 hrs/day is spent by women in fetching 15-20 litres water from a source 2
km downhill. 60% of fetched water is used for livestock and the remaining for other purposessuch as, drinking, washing, cooking, etc. There is no certainty of portable water, and the area
depends on groundwater sources, which is odourless and of very good quality by and large.
Scarcity of water resulted in competition for water resources, especially drinking water, andhence, there is high conflict potential. The problem is from the distribution point. Out of 65
water connections, 50 percent of villagers avail water without any official connection, as nowater meter provided by the authority. 29% of people have traditional knowledge of soil andwater conservation, but implementation is rare, but, they are interested in participating in suchactivities. 79% people have some land around their house and are willing to use this land for
rainwater harvesting.
According to the Census 2001, 74% males and 56% females are literate. There is only one
primary school built in 1985 with no proper facilities, and the teachers don’t come regularly.
-11-

Students are unable to acquire the knowledge of standard, and for further study go to anothervillage, 5km down hill. There is no avenue for advance education and employment for girls.
A majority of youth is not matriculate. Due to absence of Government technical or vocational
training centre, over 90% of the youth is unskilled and lack technical education of any kind.
No awareness of proper sanitation and hygiene exists. 92% of the households do not havetoilets and drainage system. No health or first aid facilities available. The nearest health centre
is at 4 km downhill. During emergency, it is difficult to reach the health centre in time due toabsence of any mode of transportation and pucca road. There are total 310 animals, of which
43% are goats, 17% buffalos, 16% bulls, 12% calf and 11% cows. Pine tree plantation haveadded new dimension to the drudgery as falling pine needles cover the ground and prevent
growth of grass. The villagers also cause Forest fire as they burn the fallen pine needles to get
rid of it.
Pressure/Vulnerability Indicators: Stratification, quarrelling with each other and absence ofcommunity feeling over issues related to water, etc. is prevalent. People belonging to upper
castes having affluence and political influence suppress and ill-treat the lower caste people
and try to dominate and command the rest. Drudgery of women exists due to unavailability ofwater, fodder, and firewood in close vicinity; women need to go to far off hillocks. Womenare vulnerable, because they feel that they cannot participate in any developmental activities
as they are illiterate or uneducated. In the absence of avenues for advance education andemployment, girls are vulnerable to early marriages. Being unaware of free health services
and facilities available, the people (especially women) are vulnerable to paying money todoctors at Government Hospitals. Men folk and youth are vulnerable to drug abuse andalcoholism. Animal sacrifice also exists, which indicates prevalent superstitious beliefs.
People are more concerned with the hamlets where they reside and wish that all thedevelopment must take place there.
Response Indicators: During preliminary meetings, village community mentioned many of
its current and future problems and expressed that if water is made available they could takeup promising livelihood options like dairy farming, herbal and organic farming, and vegetable
cultivation etc. Most of them had no knowledge about developed varieties of seeds etc. These
factors have been the cause of migration of men from the village to the cities in the search ofjob.
Output Indicators: Initial surveys and observations revealed that in the past public
participation was nil for any developmental activities. Village community had neither any role
nor were they aware about them. There existed no Self Help Group or other assemblage foraddressing the community issues. There exists absolute environmental ignorance and no
maintenance and management of existing water sources despite acute water shortage in the
area.
Context Indicators: The facilitators used visual aids to motivate the villagers and give equal
opportunity to each to voice views; guided the villagers with relevant questions in order toanalyse the situation thoroughly; created awareness on the importance of resource
conservation and Land Use Planning; and promoted self-help spirit as a means to develop,
involve and empower the villagers to address their problems and to find their own solutions.

Post-initiative visible impacts/success stories• A drastic change was seen in the attitude of the people especially women with growing
participation and cooperation in the meetings.
• Development of analytical perspective in women enabling problems identification.
• Importance of unity has been understood, as a result of which women have cometogether to take lead in the developmental activities. First women group fund has beencollected.
• The Community understood the importance of education and demand for a wellstructured and functional education system is growing.
• The Community has growing awareness towards the water related issues andwillingness to implement rainwater harvesting, if efforts are made to provide themtechnical know-how and infrastructural support for adopting advance techniques forwater harvesting.
Future scope and recommendations
The initiative provided strength and future scope in a wide range of areas: community
mobilisation and women's empowerment, promotion of education and culture, community
health management by improved water and sanitation dimensions, natural resource
management and ‘Panchayati Raj’ system. The following activities are recommended:
•

•
•
•
•
•
•

Rainwater harvesting from slanted rooftop of buildings and laying the infrastructure
for conserving water in storage tank, farm ponds, depression, etc. A technicaldemonstration of the rainwater harvesting with low cost measures and involvement of
the community.
The individual farmlands being too small and highly fragmented, group farming orcooperative system may be encouraged.
Stone concrete check dams and contour bunds can be constructed to protect soil
erosion.
Soil maintenance and regeneration can be accomplished covering the soil with crop
residues, fertilization with animal wastes, and reduced tillage.
To arrest illicit felling for fuel and timber, adopt approaches, such as, afforestation
with suitable species, comprising various species of fruit, fodder, fuel wood andtimber plants.
The villagers should be provided higher yielding hybrid varieties of good seeds ofvegetables and food grains suitable for hilly environment.
Existing agricultural practices can be modified through the adoption of an ecologicalapproach with emphasis on reducing the energy and resource-intensive inputs;
cultivation of pest-resistant plant, etc.

Abstract
The objectives of the study were to develop national stream health assessment model (NSHA)
using fish assemblages in Korea during 2003- 2005 and apply the NSHA model to 80 stream
and rivers of national major watersheds for the model tests. The NSHA model was based on
the metric index of biological integrity (IBI), which was established as a Rapid Bioassessment
Protocol (RBP) in the US EPA. For the national model developments, regional trophic guilds
and tolerance guilds were analyzed in the four major watersheds in Korea and 39 nationalreference streams were selected for developments of the maxim species richness line (MSRL).
Also, metric numbers and metric attributes of the NSHA were modified and corrected for theregional applications along with establishments of the scoring criteria. In the initial stage weselected 10 metric model and corrected as 8-metric models as a cost-effective strategy. Also,
we tested the fitting of the model on the national ecosystems in the relations with habitat
health, based on Qualitative Habitat Evaluation Index (QHEI) and conventional water quality
criteria. We identified impaired vs. healthy systems by the national biological criteria innationwide streams and rivers in Korea. The new national biological monitoring methodology
would be used as a key tool for ecological restorations and species conservations in Korean
aquatic ecosystems.
Introduction
Recently, effective management strategies for aquatic ecosystems are developing in many
developed countries (Barbour et al., 1999) and the paradigm is changing from thechemical-based to biological approach (Davis and Simon, 1995). During the last several
decades, stream water quality has been frequently evaluated by chemical monitoring such as
nutrients, biochemical oxygen demand, and hazard chemicals. However, health assessmentsof aquatic ecosystems, based on various types of aquatic taxa, have been a hot central issue
for effective water quality monitoring and this approach has been considered as a surrogate
for achieving the goal of ecological integrity in aquatic ecosystems (Karr and Chu, 2000). In
fact, Judy et al. (1984) pointed out that simple chemical measurements may not detect anintegrative health condition of water environments due to dynamic spatial and temporalvariations as well as various habitat degradations (channel modifications) and modifiedhydrological regime. This fact is supported by various quantitative habitat evaluations (Terrell
et al., 1982) and instream flow incremental methodology (Stalnaker, 1982).
Multi-metric models, based on various biological indicators and physical habitats, have been
widely applied for evaluations of integrative ecological health in aquatic ecosystems. One ofthem is a concept of "index of biological integrity (IBI) using fish assemblages and this-14-

concept was originally introduced by Karr (1981) for evaluations of water environment
reflecting physical habitat, chemical, and biological conditions in small mid-western streams,
USA. Since then, 35 states in the USA applied the IBI to wadable streams and rivers (Karrand Dionne 1991) and many other countries. The reason why the IBI is applied to world-wide
is due to cost-effective, quantitative, and multi-metric approach (Ohio EPA 1987, Karr andDionne 1991, Barbour et al. 1999 Karr and Chu 1999) that evaluates various aspects of fish
community structures and functions in a specific region. In this study, we developed national
stream health assessment (NSHA) model using fish assemblages, and applied to various
streams and rivers in Korean watersheds. Also, we compared the model values toconventional water quality (such as BOD) and physical habitat index.
Material and Methods
Field survey was conducted in 80 temperate stream and river locations during April - June
2005 and fish sampling followed after the wading method (Ohio EPA, 1989). The sampling
locations were same as the chemical monitoring sites designated by the government. At the allsites, fish collections were conducted according to the method of the catch per unit of effort(CPUE; Ohio EPA 1989); all habitat types including riffle, run, pool were sampled for a
distance of 200 m during 60 minutes. Chemical data such as conductivity, BOD, and TP wereobtained from the Ministry of Environment, Korea. Also, fish samples were collected from 39
reference streams and river sites in the Korean major watershed during 2003 - 2005 to derive
maximum species-richness lines against the stream order. In selecting the regional reference
sites, we followed the approach of Hughes (1995).
For the ecological stream health assessments, eight - ten metric model system was determined
and the model based on the 3 major attributes of species richness, trophic and tolerance guild
analysis, and individual health (Barbour et al., 1999). National ecological stream health, basedon ten-metric models, was initially categorized as five integrity classes of excellent, good, fair,poor, very poor, and worst conditions. We also analyzed the habitat quality, based on the
Qualitative Habitat Evaluation Index (QHEI; Plafkin et al., 1989). Seven habitat parameters
were selected for the assessment of QHEI, based on the references widely used (U.S. EPA,
1983). The physical habitat health conditions of the habitat were categorized as 4 ranks of"comparable to reference", "support", "partially support" and "non-support".
Results and Discussions
Preliminary metrics of NSHA model, based on the Index of Biological Integrity (IBI), werecomposed of three components of species compositions (M1: number of Korean native species,
M2: Number of riffle benthic species, M3:Number of sensitive species, M4:Number of tolerant
species), trophic compositions (M5: % omnivores, M6: % insectivores, M7: % carnivores) andfish abundance and individual health (M8: total number of native fish, M9: % exotic species,
M10: fish anormalities). In the mean time, metrics of M7 and M9 were removed from theanalysis for 8-metric models.
The values of NSHA model averaged 16.7±9.9 (n=36) in Han-River, 21.0±9.0 (n=40) in
Geum-River, 20.6±8.7 (n = 40) in YeongSan/SumJin-River, and 18.4±6.6 (n=36) inNakdong-River watersheds (Fig. 1).

Figure 1. Values of national stream health assessment (NSHA) model, based on the IBI, in thefour Korean major watersheds (H = Han-River, N = Nakdong-River, G = Geam River, Y.S. =YeongSan/SumJin River).
The overall values of NSHA, 152 observations of Korean stream and rivers, averaged 19.3 ±
8.7 (n = 172). Thus, the ecological health in Korean watershed was identified as a "*good
condition" according to the modified criteria of Karr (1981) and US EPA (1993), but there
were large spatial variation depending on the locations and seasons sampled. Pearson's
correlation analysis showed that values of NSHA model, based on IBI, were not correlated (p> 0.05) with BOD, COD, TP, and TSS. However, when we removed the data during thehigh-flow (ex, IBI values of > 35 when BOD were > 2.7 mgL-1), IBI values had high negative
correlations (r = - 0.890, p < 0.05) with BOD values. Also, TP, COD and TSS had strong
correlations with IBI when the data were removed from the analysis.
The index of biological integrity (IBI) also had strong correlations with indicator species (Fig.
2); the abundance of sensitive species increased with high values of IBI, while percent
tolerant species decreased with high IBI values. Similar pattern on IBI was shown in thenumber of individual and the number of species, as shown in the sensitive species. These
results indicate that high nutrient enrichment or organic pollution resulted in reduced themodel values and this condition modified the relative proportions of ecological indicatorspecies (sensitive vs. tolerant species).

Figure 2. Relations of the Index of Biological Integrity (IBI) on the sensitive and tolerant
species, the number of species and the number of individuals.
As shown in Fig. 3, values of IBI had high variations when the BOD values were low (1 - 2
mg L-1), and the values had low variations when the BOD values were high (4 - 5 mg L-1). In
other words, when water quality, based on BOD, was good (1 - 2 mg L-1), the stream health
was judged from 1st rank (excellent condition) to 4the rank (poor condition), indicating a highvariation. In contrast, when the water quality was bad (4 - 5 mg L-1), IBI was judged as poor very poor conditions, indicating that the stream health, based on IBI, reflects directly theorganic matter pollutions.

Fig. 3. Relations of the criteria IBI calculated vs. BOD criteria measured. The alphabets
indicate the streams sampled.

Also, case study in the SumJin / YoungSan Rivers showed that when the BOD values were >2.5 mg L-1, IBIF values (Index of Biological Integrity using Fish) were low, even if the QHEI
values were > 50 (Fig. 4). In contrast, when the BOD values were < 2.0 mg L-1, IBIF values
had linear functional relations with QHEI. These outcomes indicate that when the chemical
water quality is good, the health conditions in the streams and rivers are directly determinedby the habitat health as shown in the Fig. 4. Overall, our results suggest that the ecologicalstream health in this study was due to combined effects of chemical degradations and habitat
degradations. Especially, when the chemical water quality was very good (< 2.0 mg L-1 as
BOD), still the ecological health showed large variation, so that simple chemicalmeasurements may not detect actual conditions of the ecological health.

Figure 4. Case study of SumJin/YoungSan Rivers on the relations of BOD, biological water
quality, based on IBIF (Index of Biological Integrity using Fish), and Qualitative habitat
Evaluation Index (QHEI).
This assessment could diagnose the currents health conditions in Korean watershed, so thisnew monitoring approach may be used as an important management tool for efficient
ecosystem managements and restorations.

Abstract
Depletion of water quality in Thailand has become a serious problem in recent years. The
objective of this study was to mobilize river conservation and monitoring activities in Ngao
River, a Mekong tributary in northern Thailand by involving elementary and junior highschools. The project was divided into four activities: i) field survey, ii) illuminating workshop
and network stimulation, iii) students activities on river conservation, and iv) presentation ofschool and student activities.
The research found that use of actual situations in the district and outdoor training programs
are effective to educate children and increase their awareness on river water quality issues.
Students are keen to participate in the project; many of them investigated simple water quality
indicators such as temperature, water velocity, transparency, total solids and diversity ofaquatic life. Some schools arranged an awareness raising program to promote riverconservation in the community. Some volunteered to dredge and collect waste from the river.
The results clearly revealed that the schools and the students can play a major role inmeasuring simple water quality indicators and monitoring the river ecosystem. Further, they
can convince other children, residents and local organizations to be more interested in andresponsible for conservation and monitoring of the river environment. This could eventually
establish a strong community network, driven by the schools, for rehabilitating andmonitoring the river and ecosystem in this watershed.

Introduction
Wiang Kaen District, Chiang Rai, Thailand, is a landlocked area adjacent to Lao People’s
Democratic Republic. The north is bordered by the Mekong River and the east by the Doi
Prae Muang and Doi Pha Mon mountains. The land is mountainous with an elevation ranging
from 310 to 1,625 meters above mean sea level (Sang-Arun et al., 2006). The area has one
main river called the Ngao River which flows from the high land in the south to the MekongRiver (Fig. 1).
Local people have had a close relationship with the river for a long time. Most of them use the
Ngao River as the main source of water for their daily consumption, crop cultivation, and soon. However, the ecosystems of the Ngao River have changed a great deal in more recent
times. Many organizations in the Wiang Kaen District now pay close attention to the river-20-

ecosystems; however, the problems of low water quality and degradation of the ecosystemhave not been solved. The government tried to dredge the river, though this can also impact
the ecosystem negatively, and organized an event to promote the use of traditional practices toconserve the river.

Figure 1. Study area in Wing Kaen District, Chiang Rai Province Thailand.
The objective of this study was to mobilize river conservation and monitoring activities in
Ngao River, a Mekong tributary in northern Thailand by involving elementary and junior highschools.
Project activities
The project comprised four activities: i) field survey, ii) illuminating workshop and network
stimulation, iii) students and school activities on river monitoring and conservation, and iv)
presentation of schools and students’ activities. The field survey was conducted in June 2006.
An investigation into local practices which affect water quality was carried out. The
illuminating workshop was organized in August 2008. The workshop invited dialogue on therole of each sector in solving the problems of the river. The target groups were elementaryand junior high school students in the district. These schools are located not so far from theriver’s tributaries thus there is high potential for them to monitor the river quality and its
ecosystem. Also there is a high potential to encourage them to build up an active rivermonitoring network. Relevant stakeholders and Government officials were also invited toparticipate in the workshop. This workshop aimed to improve the communities’ knowledge
and understanding of the current environmental situation, natural resource management
principles and the positive role that local communities can play in environmental
management. The workshop activities included i) a presentation of water quality and the river
ecosystems of the Ngao and Mekong River, ii) identification of factors inducing degradationof river quality and ecosystem, iii) outdoor training of simple water quality measurement andecosystem observation, and iv) brainstorming session and drawing activities. The workshop
involved school teachers and trained junior-high school students to facilitate the workshop.

After completion of the workshop, each school was given responsibility for monitoring water
quality in their area. Equipment was distributed for students to conduct the measurements.
After six months, in February 2007, a program to evaluate the success of the project wasundertaken. Students were requested to present and share experiences.
Results and discussion
Impacts of activities on river ecosystems
The results of field surveys showed that there were four main activities that induced
degradation of water quality and river ecosystem in Wiang Kaen District. These activities
were identified as the main causes for poor water quality, drop in river depth, high river bankerosion rates, and water scarcity even in the rainy season due to high turbidity of the water.
i) Deforestation and land use change
An increasing population has directly affected land use and deforestation rates. In Wiang
Kaen District there are at least nine minority groups: Lanna, Lue, Mong, Lahu or Muser,
Myan, Khmu, Chinese, Akha and Yao. Most of them base their farming practices on shifting
cultivation in mountainous areas which is well recognized as a cause of deforestation.
Another cause is land use change from forest to cultivated land for staple and cash crops. Thispressure has an affect on the headwater forest area and the water quality in the Ngao River.
Sang-Arun et al (2006) estimated that over 40% of the reserved forest area in Wiang Kaen
was encroached for the cultivation of annual crops and the planting of orchards (Fig. 2a).
abcFigure 2. Main causes of degradation of water quality and river ecosystem of the Ngao River
Watershed and their impacts: (a) unsustainable farming practice in high mountainous area, (b)river bank erosion, and (c) gold mining in the river.
ii) Unsustainable farming practiceThai farmers use a number of agricultural practices which were found to have negativeenvironmental impacts. The farmers in the Ngao River watershed prefer to plant monocrops
such as corn and ginger. The cultivation of such crops can readily cause soil erosion because
their root systems are weak and shallow. Further, overuse of herbicides and pesticides
polluted the river.
iii) Non-ecological friendly riverbank management practiceDue to high erosion rates, the depth of the river has decreased. The Government decided toincrease the depth and width of the river by dredging. The riverbanks ecosystems weredestroyed by the dredging and there were very few restoration programs. Further, surrounding-22-

the river and the headwaters is an area where slash and burn agriculture practice is common.
Therefore, every time it rains there is a high level of sediment in the river turning it red incolor. Additionally, the river bank suffers from high erosion rates (Fig. 2b). The result is that
infrastructure such as roads and bridges and cultivation areas adjacent to the river weredestroyed.
iv) Gold mining
A part of the district in the hilly area has gold deposits. Local residents conducted traditional
gold mining in the river (Fig. 2c). This practice caused high turbidity of the river andincreased the accumulation of downstream sediment.
The students’ awareness of river ecosystem problems
Nineteen schools located in the district participated in the workshop which included
presentation of the results of field surveys on river quality, river ecosystems, and practicalfield training on simple river quality monitoring techniques (Fig. 3). The results of theworkshop show that the participating students could understand simple water quality
measurement techniques using local materials available in the district. They were also able toidentify the current problems of the Ngao River such as high sediment load, river bankerosion, and potential chemical contamination.

Figure 3. Outdoor training activities for simple river quality measurement and monitoring
techniques.
After a brainstorming session, several methods were identified to solve the many problems
facing the river ecosystem, for example, reduction in the use of chemicals and pesticides
during cultivation, the planting of more trees in the highland areas to reduce soil erosion andsubsequent sediment loads in the river. To encourage the children to understand the need for aclean and healthy river they were asked to imagine the river as it was in their dreams and to
sketch what they imagined.
The parameters and the condition of the river that schools are observing and measuring areaverage rainfall, types of land utilisation near the river, river colors, smells, water level, river
velocity, temperature, transparency, total solids and aquatic life. The students proved to bevery active and enjoyed using the equipment for the monitoring of the river (Fig. 4). Huay
Han School, Ban Muang Yay School and Ban Thakham School actively introduced the simple
water quality measurement into their science education program. A preliminary study onwater quality in river and reservoirs was carried out by students who investigated the causesof water pollution. Khunkwak Pittaya School, Ban Saithong School and Ban Thakham School
were very keen to monitor aquatic life in the river. Students in Ban Huay Ian School monitor-23-the Mekong Riverside ecosystem regularly and have protested illegal rock trafficking. Ban
Thakham School, Poh Wittaya School and Pang Hud Sahasad conducted an awareness raisingprogram to promote river conservation in the community and organized an event to clean andcollect waste from the river.

Figure 4. Student activities for monitoring water quality and river ecosystems.
The school network for water and river monitoring
In February 2007, eleven schools presented their activities on river conservation andecosystem monitoring at Khunkwak Pittaya School (Fig. 5). This activity provided evidence
that the schools and students can be effective in monitoring the river quality and its
ecosystems. They are able to use simple equipment effectively and carry out basic scientificobservation reliably. They are able to identify correctly the many land use types which havean impact on the river. Further, they can convince other children, residents and localorganizations to be more interested in and responsible for conservation and monitoring ofriver environment. This could eventually establish a strong community network, driven byschools, for rehabilitation and monitoring of the river and ecosystem in this watershed.

Figure 5. School exhibitions.
Another result of the student presentation and school exhibitions is that schools can help plan
the monitoring and future restoration of the river. Through collaboration with all stakeholders
in the area, it has been agreed to set up a schools’ river and environmental monitoring
network which will be supported by local government and the private sector. Ban Saithong
School volunteered to coordinate this network to ensure momentum of these activities in the
district.
Community environmental management by school network mobilization
Inspired by the outcome of students’ activities, Ban Saithong School proposed to build a riverconservation network and continue the activities. The School Principal volunteered tocoordinate the network. The schools’ network will prepare the local environmental curriculum-24-

in Ngao watershed and mobilize the development of the local community plan which is to be
set up by local government. This could help convince related stakeholders in the area to pay
more attention to river conservation from a broader perspective than merely dredging the river
channel. The research indicates the benefits of involving students in measuring andmonitoring river water quality and ecosystems. The students are a valuable and importantresource that can make a vital contribution to conservation and restoration of the river and its
watershed. The students can serve as a catalyst for participation from other sectors in thecommunity for the creation of a strong network for conservation and monitoring of water
quality and river ecosystems in the watershed.
Conclusion
The participation of local schools in water quality and ecosystem monitoring in Wiang KaenDistrict was a successful and novel way to make them aware and understand the values andimportance of environmental conservation. In addition, students provided a service to thecommunity as a monitoring group. They can further pass on this knowledge to their families
and broader communities.
Schools proved resourceful in soliciting funding and formulating proposals for riverconservation to the relevant stakeholders, government and private sectors. The initiative of
these schools can lead to further collaboration, development of monitoring plans, andmobilization of community involvement in river conservation. Other sectors can play animportant role by setting up planning and policies to support the required budget andequipment needed.

Abstract
During the last few years, MBR (membrane bio-reactor), a promising process combination ofactivated sludge treatment and membrane filtration, came through remarkable progress in
China, both in academic research and commercial application. This paper provided an
overview of the research and application of MBRs in wastewater treatment and reclamation in
China. Particular attention was paid to the research progress related to membrane fouling andcontrol, new MBR processes, and target wastewater types. Some case studies for MBR
commercial application and main organizations related to MBR in China were provided at theend of this paper, followed by the challenges and future visions of this technology.
Keywords: membrane bioreactor (MBR), wastewater, treatment, reclamation, China, review
Introduction
Since 1966 when Smith, et al. first employed membrane bioreactor (MBR) for wastewater
treatment, this technology has received increasing attention around the world. MBR is
operated similarly to a conventional activated sludge (CAS) process, with the exception that
membrane filtration is employed to separate effluent from activated sludge instead of
secondary clarification. This substitution eliminates the sludge settling challenges associatedwith a clarifier, coupled with many other advantages including reduced footprint, low sludge
production, stable and high quality effluent, easy automation, etc.
In China, research on MBR started from 1991 when Chen (1991) published the first paper in
one Chinese journal on MBR application for wastewater treatment in other countries. Fromthen on, many universities and research institutes had involved in research on MBR process.
These included Tsinghua University, Tongji University, Chinese Academy of Sciences (CAS),
Tianjin University, Zhejiang University and Harbin Institute of Technology, etc. To promote
development and application of MBR, Ministry of Science and Technology (MOST) of China
successively funded MBR project from 1996 under the national 9th “5-year-plan” and from2002 under the national “863” project. A number of companies, both domestic and overseasfunded, emerged during this period and dedicated their efforts to MBR development andapplication in Chinese market. To date, remarkable progress has been achieved both onacademic research and commercial applications of MBR in China. With the increment oftreatment capacity and the reduction of operation cost, MBR is anticipated to be a very
important technology for water treatment and reuse.
This paper presented the recent research and application progress of MBR in China by
critically reviewing the research achievements and specifically presenting commercial
applications in China. Main domestic organizations involved in MBR research andapplication were also provided. At the end of this paper, challenges and future development-26-

trend of MBR technology were analyzed.

Overview on MBR research in China
This section provided a review of the past academic research progress in China, which was
divided into the four sub-sections as followed.
Increment of papers and organizations on MBR research
According to the statistics by Huang et al. (2008) and Wang et al. (2008), during 1995~2006,
over 700 scientific papers written by Chinese authors were published, in which over 80%
were Chinese papers. Meanwhile, more and more organizations had dedicated their efforts to
MBR research. The detailed information for chronological distribution of Chinese papers anddomestic organizations were presented in Figure 1. As demonstrated, the numbers of papers
and organizations involved in MBR research saw a continous increase during the 12 years,
especially from 2001 to 2006. Among the published papers, about 76% were original
research papers, while the residual were review papers. Universities were the dominantorganizations for MBR research all along, though after 2000, especially during 2005 and 2006,
a number of companies and institutes joined in the research, such as Tianjin Motimo
Membrane Technology Co., Ltd., Tianjin Tsinghua Daring Co., Ltd., Beijing OriginWater
Technology Co., Ltd., and CAS. This increment of papers and organizations indicated that
MBR technology had drawn more and more attentions of individuals and researchorganizations in China in recent years.

involved in MBR research during 1995~2006.
Fundamental research on basic information of MBR
MBR configurations
MBRs are composed of two primary parts, i.e. the biological unit responsible forbiodegradation of the waste compounds, and the membrane module for physical separation of
the treated water from mixed liquor. According to their configuration, MBR systems areclassified into two major groups: integrated (submerged or immersed) and recirculated (sidestream or external) MBRs. As demonstrated in Figure 2(a), recirculated MBRs was thedominant configuration in the early studies. Though Yamamoto et al. (1989) put forward theconcept of integrated MBRs in as early as 1989, they were not popular in China until 2001.
For example, in 2000 less than 50% of the published papers were related to integrated MBRs.
However, in 2004, the ratio increased to over 95%. As compared with recirculated MBRs,
integrated MBRs consume much less power due to the absence of a high-flow recirculation
pump. This was the main reason for the popularity of integrated MBRs in wastewater-27-

treatment after 2001.

However, integrated MBRs also had their disadvantages. Because of the direct contact
between membrane module and wastewater with high organic load, membranes used in
integrated MBRs were more apt to be fouled. To solve the problem, several modified
configurations were proposed by Chinese investigators. For example, Fan et al. (2003) from
CAS developed a modified recirculated MBR (also called as airlift external circulation MBR,
AEC-MBR), combining the advantages of integrated MBRs with recirculated MBRs throughreplacing the recirculation pump by H-type recycling pipe, for the treatment of toilet
wastewater and municipal wastewater. Another innovative MBR, named as submerged
anaerobic membrane bioreactor (SAMBR), was developed by Wu and Wang in 2004. In thisnew MBR, fouling was controlled by recirculating the biogas produced by the bioreactor toinduce mixed liquor turbulence. Detailed information for other new MBR processes would be
provided in section 2.4.
Membrane materials and modules
Three membrane modules most often used in the past studies included hollow fiber, flat sheet
and tublar membranes. The main domestic suppliers and typical product parameters formembranes were summarized in Table 1. Several overseas suppliers were also listed forcomparisions. As demonstrated, the demoestic hollow fiber membranes were mainly
produced by Tianjin Motimo Membrane Technology Co., Ltd. and Zhejiang University
Kaihua Membrane Technology Co., Ltd.
And their main-stream products were
polyvinylidene fluoride (PVDF) fibers with 0.2 μm pore size and polypropylene (PP) hollow
fibers, respectively. Besides, several other membrane materials including polyethylene (PE),polyethersulfone (PES), polyvinylidene chloride (PVC), and polysulfone (PS) produced byoverseas or Chinese organizations were also applied in these studies and their characteristics
of wastewater treatment in MBRs were well investigated. As compared with hollow fibers,
flat-sheet and tublar membranes were much less supplied, with their main suppliers as
Shanghai Institute of Applied Physics and Kubota, Toray (Japan) or Nanjing University ofChemical Technology and X-Flow (Netherland), respecively. Among the published original
research papers, the vast majority focused on the study of hollow fiber membranes for
wastewater treatment while flat-sheet membranes were only intensively studied by Tongji
University and few institutes in China. Ceramic membranes, as shown in Table 1, were also
researched in China due to their special qualities including the resistance against extreme pH,
temperature and pressures and the tolerance of rigorous cleaning with acid, alkali and hot
water.

Overall, domestic membrane modules had the advantage of low cost as compared with thatfrom overseas. However, their performance still needed to be promoted. In the future,membranes with high performance and low cost should be developed to expand the market
for domestic membranes.

Research contents
According to the previous studies as demonstrated in Figure 2, MBR research contents werefocused on two aspects: membrane fouling and control, and application of MBR for treatment
of different water and wastewaters.
Membrane fouling and control
Membrane fouling is a major obstacle for wide application of MBRs. It results in severe flux
decline, high-energy consumption and frequent membrane cleaning or replacement. For the
better operation of a MBR, causes, mechanisms, and control of membrane fouling should bethroughly investigated.
A number of investigators in China had dedicated their efforts to the study of causes andmechanisms of membrane fouling. They suggested that membrane fouling was significantly
influenced by the feed water characteristics, membrane type, and hydrodynamic conditions.
Based on these studies, a general understanding of membrane fouling could be established: 1)
Sludge cake layer, formed mainly by bioflocs, has strong effects on membrane permeability; 2)
Soluble microbial product (SMP) and extracellular polymeric substances (EPS), which areeasily adhered to membrane surface to form “gel layer”, have significant correlations withmembrane fouling; 3) A proper sludge concentration (TLSS) should be maintained tofacilitate MBR performance; 4) Other parameters like feed water characteristics, sludge
components, operation conditions, etc. all have correlations, to some extent, with membrane
fouling.
Several methods were employed for the detection of membrane fouling. Typical methods
were by the increase of transmembrane pressure (TMP) or by the decline of permeate quality
or flux. However, these methods had the disadvantages of delayed response and long time-29-

needing, etc. To solve this, instrumentation techniques including SEM, AFM, and FTIR werealso used for fouling identification. Besides, Li et al. (2005) from Tianjin Polytechnic
University proposed a new technology, i.e. ultrasonic sensors (UTDR, Ultrasonic TimeDomain Reflectometry) for fouling detection. This approach had the advantage of aquiring
information for the extent of biofouling in real time.
On the basis of the understanding of fouling mechanisms and characteristics, many effective
and applicable measures had been studied and developed to control membrane fouling. Four
following aspects of attempts were the focus of research on MBR fouling control.
1) Feed adjusting. Experts from Tsinghua Univerty developed several feed adjustingprocesses for control of membrane fouling. In their studies, powdered and porous materials
such as powdered activated carbon (PAC) and zeolite, and coagulants including Al2(SO4)3,FeCl3, polymeric aluminum chloride and polymeric ferric sulfate (PFS) were added into
MBRs to modify the filterability of mixed liquors. It was found that membrane fouling was
reduced after PAC or coagulant addition among many studies. Besides, a lot of other
innovative attempts were also made in Tsinghua University for membrane fouling control,
such as MBRs seeded with granular sludge and MBRs coupled suspended carriers. The main
goal was to reduce the fouling caused by fine particles in the system or to obtain better
hydraulic conditions through the carrier’s movement induced by aeration.
2) Fabrication of membranes. Characteristics of membrane materials, including wettability,
pore size and surface charge, were reported to have close correlation with their foulingcapabilities. Among them, surface wettability was deemed as the dominant factor. Generally
speaking, the more hydrophilic membrane always resulted in less fouling. On this principle,
several membrane fabrication methods were proposed by some authors. For example, Xu andYu (2005a, b) from Zhejiang University modified PP hollow fibers by plasma-induced
immbolization of poly(N-vinyl-2-pyrrolidone) (PVP), plasma treatment with air, O2, Ar, CO2,
and H2O or UV-induced graft of acrylic acid. While Lu et al. (2005) from Harbin Institute ofTechnology prepared the organic-inorganic composite membranes by addition of nano-sized
Al2O3 during the PVDF membrane preparation procedure. After these fabrications,antifouling properties of the membranes were demonstrated to be significantly enhanced.
3) Optimization of operational conditions and parameters. Operational conditions play a keyrole in MBR process, and optimized conditions and parameters are very conducive to reduceand control membrane fouling. It has been well recognized that critical flux is an importantconcept in integrated MBRs, below which the increase of TMP or the decline of flux withtime does not occur, while above that level fouling is observed. Many researchers focused on
the study of critical flux in MBR and identified that sub-critical operation was suitable for the
integrated MBRs. Under sub-critical operation, MBRs could achieve long-term, stable
operation without frequent membrane cleaning. Besides, other operational parameters
including dissolved oxygen (DO) concentration, aeration intensity, the ratio of suction andnon-suction time during intermittent filtration, sludge retention time (SRT), hydraulicretention time (HRT), filtration modes, sludge concentration, and temperature were suggested
to be optimized for reducing membrane fouling.
4) Surface Cleaning. Although the above-mentioned measures could control membrane
fouling to some extent, the decrease of membrane permeability is inevitable attributed to poreclogging, biofouling, etc. Once operational pressure increases dramatically to a certain value,-30-

membrane cleaning procedure is needed to recover the membrane permeability.
Physical cleaning is one popular method for such purpose, aiming at the reversible foulingcaused mainly by deposition of bioflocs and pore clogging. Typical physical methods include
aeration, water back-flushing, and sonication, etc. Among them, back-flushing is an effective
way for high-pressure-resistance membranes, such as hollow fiber and ceramic membranes.
Other physical cleaning methods were also studied and developed in China. For example, Xu
and Fan (2004) developed a hollow fiber membrane module with enhanced self-mechanicalcleaning function which was suitable for high sludge concentration and flux operation. Sun etal. (2003) adopted sponge scouring to remove the fouling in a submerged flat-sheet MBR. It
was also found that application of ultrasound could effectively reduce membrane fouling in aside-stream anaerobic MBR for high-strength synthetic wastewater treatment (Sui et al. 2006).
However, for irreversible fouling caused primarily by surface gelation, some chemical agentsshould be applied for membrane cleaning, such as acids (hydrochloric acid, sulfuric acid,citric acid, etc.), alkali (sodium hydroxide), and oxidants (sodium hypochlorite, perhydrol,etc.). Their effects on foulants removal were extensively identified. A general conclusion
could be drawn from these studies that acids can effectively remove inorganic foulants whilealkaline solution and oxidants perform well in removing organic substances and biofouling.
Much higher cleaning efficiency could be reached by employing multi-step chemical cleaning,for instance, sodium hypochlorite cleaning followed by acid and/or alkaline cleaning.
Overall, membrane fouling and control strategy are two closely interrelated hot topics of theresearch on MBR technology. The ultimate goal is to propose corresponding fouling control
methods and to facilitate MBR stable operation. With the deep understanding of membrane
fouling mechanism in MBRs, more efficient and convenient control strategy would be
developed in future. Another issue that should be addressed is that the fouling control
strategies in full-scale MBR plants, especially large-scale MBRs, are insufficient in China.
Fouling control measures mentioned above are proposed just based on lab-scale or pilot-scale
MBRs, and their fouling control efficiency in full-scale MBRs need to be further verified.
Target wastewaters
As demonstrated in the papers distribution (Figure 2), a large number of studies were carriedout for the purpose of wastewater treatment and reclamation. The most often applied
wastewaters were municipal/domestic wastewater, followed by industrial wastewater andother kinds of water. Besides, the number of papers on industrial wastewater treatment
increased annually, indicating that MBR process was increasingly popular in the treatment ofindustrial wastewater, particularly high strength and refractory wastewater. This was due toits advantages of independent selection of HRT and SRT and the corresponding high sludge
concentrations and development of specialised, slow-growing microorganisms. Anotherapplication of MBR systems in industry was in the area of landfill leachate treatment. As
compared with municipal and industrial wastewater treatment, studies on the application of
MBR for surface water treatment in China, were much less. Considering that the surface
water pollution in China is very severe, more research efforts are needed to ensure drinking
water safety. MBR, as a promising process, is expected to play an increasingly important rolein surface water treatment in vast areas of China in the near future.

New progress of MBR processes in China
In recent years, aiming at the disadvantages inherent in integrated or recirculated MBRs,
researchers in China made some improvements on MBR configuration. And some new MBR
processes were developed, which could attain to better pollutant removal and more stable
operation. The aforementioned AEC-MBR and SAMBR were two of them. For example,
AEC-MBR had been successfully applied for treatment of toilet wastewater (Xu and Fan.
2003), both reducing cost and optimizing cleaning. The new MBR processes were divided
into the following five aspects.
Hybrid MBRs
A hybrid MBR combines the pretreatment processes including adsorption, coagulation andothers with membrane bioreactor or adopts the hybrid bio-reactors. Powered adsorbents,
such as PAC and zeolite, and coagulants were studied for the pretreatment as suggested byexperts from Tsinghua University. While in the hybrid bio-reactors, biofilm or biologicalcontact oxidation were used in acompany with the activated sludge. These hybrid MBRs not
only produce treated water with excellent quality but also show much lower membrane
fouling than the conventional MBRs.
Anareobic MBRs
Aerobic MBRs were the dominat configuration in the early studies. Recently, anaerobic
bioreactors including continuous stirred tank reactor (CSTR) (Wu, et al. 2001), expanded
granular sludge bed (EGSB) (Chu, et al. 2005), and upflow anaerobic sludge blanket (UASB)(Wang, et al. 2006) were combined with membrane filtration to produce the anaerobic MBRs.
They were primarily employed for the treatment and reclamation of high strength wastewaters,such as food processing wastewater. However, due to the absence of aeration, membranes inanaerobic MBRs are more apt to be fouled. Several anti-fouling methods were thus proposedby several authors including optimization of opearation conditions and suction modes (Wang,et al. 2005a, b), methane circulation (Wang, et al. 2006), and combination of sonication withanaerobic MBRs (Sui, et al. 2006).
Aerobic Granular Sludge MBR
Aerobic granular sludge had recently received growing attention of researchers andtechnology developers worldwide due to their advantages over activated sludge, such as good
sedimentation, high biomass retention, high organic load, and having micro-environments for
simultaneous nitrification and denitrification (SND). However, to date, aerobic granular
MBRs are still in pilot-scale studies.
Enhanced nutrient removal by MBRs
Nearly all kinds of processes for nutrient removal could be applied in MBR, e.g. sequencing
batch reactors (SBR), A2/O process.
Genetically engineered microorganism (GEM) assisted MBRs
Overview on MBR application in China
MBR technology has great potential applications in wide ranges of waters including
municipal and domestic wastewater, industrial wastewater, landfill leachate, groundwater anddrinking water, etc. The technical and economical feasibility of this process has been
demonstrated through a number of bench and pilot scale research studies. Full scale systems-32-are also operated in many parts of the world and substantial growth in the number and size of
installations is anticipated for the near future. This section provided some case studies of
MBR commercial application for wastewater treatment and reclamation in China. Main
domestic organizations involved in MBR research and application were also presented at theend of this section considering the close ccorrelation between these organizations and MBR
applications.
Case studies
The first MBR project for municipal wastewater treatment and reclamation was installed in
Dalian city of East-North China in 1998 by DAIKI Project Environmental Protection (Dalian)Co., Ltd. Following this, a number of MBR systems were constructed in China for municipal
and industrial wastewater treatment and reclamation. Up to 2006, the total number for fullscale MBR plants came to 254 (Wang, et al. 2008). They were constructed by both homegrown companies such as Tianjin Motimo Membrane Technology Co., Ltd. and Beijing
OriginWater Technology Co., Ltd. and overseas-funded companies like Toray (Japan), Zenon(Canada), Mitsubishi-Rayon (Japan), etc. In East and South China, the constructed MBRs
were mostly involved in high strength industrial wastewater treatment, while in North China,
MBRs mainly focused on municipal wastewater treatment and reuse. Some case studies for
MBR application in China for wastewater treatment and reclamation were listed in Table 2.

1) MiYun wastewater reclamation project (MBR)
MiYun MBR plant, situated in the northeast of Beijing, was co-designed by Tsinghua
University and Beijing Guohuan Tsinghua Environmental Engineering Design & ResearchInstitue and constructed by Miyun County Bureau of Water Resources from September 2005
to April 2006. It was one of the largest water reclamation plants aroud the world, adopting thepromising MBR technology and the advanced SteraporeSADFTM hollow fiber membrane
module supplied by Mitsubishi Rayon, Japan. The design capacity was 45,000 m3/d. And thereclaimed water was mainly used as landscape water or for toilet washing, car washing,virescence, industries, etc.
2) BeiXiaoHe wastewater treatment plant
BeiXiaoHe Waste Water Treatment Plant, located in the north of Beijing, was one important-33-

water supplier for Beijing 2008 Olympic Games. The plant enlargement project, ended in
March 2008, involved the addition of a completely new wastewater line, designed for water
reclamation and with capacity of 60,000 m3/d. This progressive process, using advanced
MBR technology with hollow fibre membranes supplied by Memcor Memjet as themembrane module, guaranteed environment-friendly water reuse in the Olympic Village
central area, fountains and lakes. After enlargement, BeiXiaoHe became one of the world’s
largest MBR plants.
Industrial wastewater
1) Food wastewater
Food wastewater was one of the main target wastewaters for MBR application. Operation at
HuiLian Food Co. (BeiJing) and ShangHai Asia Pacific Food Co. (Shanghai) demonstrated
that this process could be efficiently employed for food wastewater treatment.
2) Petrochemical wastewater
Representative MBR projects for petrochemical wastewater treatment involved thoese locatedin BaLing Petrochemical Co., LuoYang Petrochemical Co. and DaYaWan Petrochemical
Industrial Park. All the above three were installed by NOVO Environmental Technology Inc.
Up to present, DaYaWan MBR plant was the largest in China for industrial wastewater
treatment, with a densign capacity of 25,000 m3/d.
3) Cigarette wastewater
The wastewater treatment and reclamation project constructed in XuZhou Cigarette Factory
was designed by Tsinghua University and for treatment of mixed domestic and industrial
wastewater. The design capacity was 2,000 m3/d. This project was the first time forapplication of MBR-RO process in cigarette wastewater treatment in large scale. Advanced
airlift MBR was used to cut the energy cost in operation. And the PVDF tublar embrane
modules were supplied by Norit X-flow (Netherland) with the pore size of 150,000 Dalton.
Micro-polluted water or drinking water
WenYuHe purification project
WenYuHe purification project was built to improve the water quality of WenYuHe. The
influent was river water below class from WenYuHe. While after MBR purification, theeffluent was increased to about level and discharged into ChaoBaiHe. The design capacity
was 100,000 m3/d with 0.1 μm hollow fiber as the membrane module. This project was thelargest project around the world for purification of micro-polluted river water and inter-basinwater transfer.
Main organizations
Main organizations involved in MBR research and application included universities (e.g.
Tsinghua University, Tianjin University, Zhejiang University, and Tongji University), research
institues (e.g. Research Center of Eco-Environmental Sciences, CAS, Shanghai Institute ofApplied Physics, CAS), and companies (e.g. Beijing Origin Water Technology Co., Ltd.,
Tianjin Motimo Membrane Technology Co., Ltd., Zhejiang University Kaihua Membrane
Technology Co., Ltd., Tianjin Tsinghua Daring Co., Ltd.). They contributed a lot to theprogress of MBRs in China.
For example, experts from Tsinghua University has made great improvements on MBR
configurations and developed several new MBR processes, such as fluidized bed MBR, PAC-34-

or coagulant-MBR process, GEM-MBR process. Besides they did a beneficial contribution toboth mechanisms and controls of membrane fouling. And the main MBR projects designed
by Tsinghua University included MiYun sewage reclamation project, Airlift MBR in XuZhou
Cigarette Factory, Tianjin Kingway Brewery wastewater treatment plant and MBR project at
HuiLian Food Co., etc.
Beijing OriginWater Technology Company is a leading company in water resource recycling
technologies, especially in the research and fabrication of membrane modules and MBR
systems. The main-stream products of this company, including standardized MBRU series ofmembrane modules, intelligentize integrated MBR system, and compact wastewater treatment(CWT) system, have been successfully applied in many wastewater treatment and reclamation
projects. For example, intelligentize integrated MBR system developed by OriginWater had
been used in TangHeKou wastewater treatment and reclamation project in HuaiRou, Beijing.
Besides, 3AMBR (Anoxic-Anaerobic- Anoxic Membrane Bio-Reactor) process was also
developed in this company for nutrients removal. Successful application of 3AMBR in casestudies were WenYuHe and MiYun MBR projects.
Tianjin Motimo Membrane Technology Ltd. is the largest manufacturer of hollow fiber
membranes in China. It manufactures a comprehensive range of both ultrafiltration (UF) andmicrofiltration (MF) hollow fiber membrane modules mainly using PVDF material. What’smore, Motimo has established dozens of large-scale demonstration projects for membrane
applications in municipal, industrial, hospitals, hotels and residential sewage treatment andreuse. Motimo is one of the few companies to have such a range of both membrane materials
and application technology to deal with filtration and separation challenges.
Novo Envirotech Co. Ltd (Guangzhou & Tianjin) are wholly-owned subsidiary to UnitedEnvirotech company. They have advanced membrane technologies and abundant experiencesin wastewater treatment. The UE-MBR technology developed by Novoet has been widely
applied for wastewater treatment, such as BaLing, LuoYang and DaYaWan petrochemical
wastewater treatment.
Challenges and future vision of MBR
MBR process is an attractive and promising technology for wastewater treatment andreclamation. However, up to date, there are still several challenges for this process. Firstly,
characteristics and performance of membrane materials and modules need to be improved,
such as the membrane’s lifespan, mechanical strength, anti-fouling properties, cost, and flux.
And standardizd modules with high treatment capacity and low energy cost should be
developed. Secondly, membrane fouling would keep to be the primary challenge for MBR
application in the future. The associated fouling mechanisms should be further understoodand more effective fouling control methods should be developed. Thirdly, new MBR
processes should be developed and operation condtions and parameters still need to be
optimized to decrease the energy cost further.
With the progress of MBR process, this technology is anticipated to play a more importantrole in the wastewater treatment and reclamation in future. It would become more and more
attractive for municipal/domestic wastewater treatment with the increasingly stringent
discharge standards and the great need of water reclamation and reuse, especially in North orNorthwest China due to the shortage of water resources. And the application of MBR process-35-

in industrial wastewater treatment is also expected to gain more popularity in China. It is
worth pointing out that studies on the application of MBR technology for surface/drinking
water treatment would be boosted profoundly in China in the near future considering that thesurface water pollution is very severe and more than half of the domestic watersheds havebeen contaminated. Besides the extension of the application fields for MBRs, the treatment
capacity and plant scale are expected to increase further.

Abstract
Water supply is a major problem that local authorities find difficult to handle. Communities inperi-urban areas are often not served by the municipal systems due to limited capacities of
local authorities. This paper presents the experience and lessons gained in implementing acommunity-built and managed water quality improvement demonstration project in Phnom
Penh, Cambodia. The project attempted to demonstrate that clean water can be supplied at anaffordable price to the urban poor, by adapting appropriate technologies and a participatory
development process. The project used simple technology that ordinary people can understandto treat rain water harvested in an earthen pond. Ferro-cement technology was used toconstruct most components of the treatment system in order to be cost effective. The selectionof these two technologies enabled to construct the system within a limited budget. The project
also demonstrated that tapping of latent social capital can make community projects of thisnature feasible. The output results of the project show that harvested rainwater with highturbidity can be treated to acceptable standards using appropriate technology. The outcome
results show that project could significantly reduce physical and financial burden on people.
The paper also outlines the measures taken to ensure the sustainability of this demonstration
project.

Introduction
Safe and clean water is a basic need for living. However, many local authorities in developing
countries are unable to provide safe drinking water for every citizen. Currently more than 1.1
billion people in the world lack access to safe water (World Bank, 2008). While people living
in rural areas can rely on natural water sources to meet their fresh water demand, people
living in urban areas face serious problems if they cannot afford to buy water from service
providers. This problem is even more acute in peri-urban areas where there exist no municipal
water distribution systems. People living in such areas have to rely on water transported by
vendors or surface water sources such as rivers and canals or ground water. It is very
commonly observed that both surface water sources as well as ground water in peri-urban
areas are contaminated by agro-chemical residues. This is especially the condition of
rainwater that is harvested from fields and stored in open ponds.

-38-

In South-East Asian countries rain water harvesting for domestic use is a traditional practice.
People have been using large clay jars or earthen ponds to store harvested rainwater. Clay jars
have been replaced by cement jars with the developments in Ferro-cement technology. This
technology is used not only for making traditional shapes of jars but also for cylindrical jars
with bigger volumes for storing and supplying water. However, there is not much attempt to1
use the Ferro-cement technology for water treatment systems. Instead, the conventional
reinforced cement-concrete (RCC) technology is often used even in small scale constructions.
RCC constructions are inherently very costly and therefore unaffordable for communities andhouseholds who want to improve their water treatment systems. Therefore, community built
water treatment systems require less costly yet appropriate construction technologies andtreatment systems.
This paper presents the lessons learnt in adapting Ferro-cement technology to construct a
community built and managed water supply system in a poor suburban community in Phnom
Penh, Cambodia. This initiative was implemented as an alumni demonstration project under
the South-East Asia Urban Environmental Management Applications (SEA-UEMA) Project,which is a partnership project between the Canadian International Development Agency(CIDA) and the Asian Institute of Technology (AIT), Bangkok. The demonstration projects
component of the SEA-UEMA Project intends to demonstrate three ideas.
1. Involving alumni of AIT as Change Agents for improving urban environmental qualities.
2. Adaptation of appropriate technology and transfer of knowledge for community based
environmental management initiatives.
3. Mobilizing communities for finding solutions for their environmental problems through aparticipatory process.
The demonstration project in Phnom Penh was implemented by Mr. Abdul Rashid Khatri, agraduate of the Human Settlements Development Program of AIT. He is attached to an NGO
in Phnom Penh. Ms. Va Dany, an Environmental Engineering graduate of AIT and a faculty
member of the Royal University of Phnom Penh, provided technical expertise for designing
the water treatment system. Dr. Kyoko Kusakabe, a graduate of the Gender and Development
Program of AIT and a faculty member of AIT, served as the gender expert. The author of thispaper, who is also a graduate of the Urban Environmental Management Program and a faculty
member of AIT, acted as the coordinator of this team of change agents.
The demonstration project was implemented in the Tropeang Chork Community, which islocated 24 km from the city center in the Sangkat Prey Veng in Phnom Penh. Although thiscommunity is located in the area of jurisdiction of Phnom Penh Municipality, no municipal
infrastructure network has reached there yet. Even the access road that passed the community

Ferro-cement is a composite material which consists of cement, sand, and wire mesh as reinforcement. A
Ferro-cement structure can be as thin as 2-5 cm, much thinner and lighter than poured concrete structures.
Because it has wire reinforcing distributed throughout the structure, Ferro-cement structures have equivalenttensile strength with ordinary concrete but have higher flexibility. It has comparable tensile strength withconcrete structures as required for water tanks. For certain types of structures, a cost comparison between Ferrocement and RCC is about 1:2 . This is a significant cost saving for limited budget projects and other low-cost
constructions. Different with conventional concrete structures which require high skilled labor, Ferro-cement
structures do not need skillful labor to build. With this advantage, Ferro-cement structures can be constructed inremote areas utilizing available unskilled local labor. However, a skillful technician should oversee theconstruction process (Nedwell and Swamy, 1994).

was a dirt road at the time of launching the demonstration project. Presently it ismacadamized. It will take more time for other basic infrastructure such as water supply toreach the community.
The community used to meet it water needs in different ways. During the rainy people
collected water from the roofs and stored in ferro-cement containers (jars or cylinders) for
future use. During the dry season some people brought water from a pond that is located about
1.5km away from the community. That water was used for domestic purposes and theybought drinking water from a vending truck which came to the community from time to time.
When a road improvement project funded by a local NGO called Urban Resource Center(URC) dug a pit to obtain soil, a pond was automatically created where the community could
harvest rain water. However, water in the pond is muddy and full of silt. The above mentioned
demonstration project funded by the SEA-UEMA Project was initiated to implement atreatment system that is not only affordable and manageable to the community but also
effective in removing silt and other impurities from raw water drawn from the pond. Moreover, the team of change agents who initiated the project faced the challenge of organizing thecommunity to collectively operate and manage the system on a cost-sharing basis. Cost
sharing was essential to deliver clean water to households at a price lower than that ofitinerant water vendors. Therefore, as demonstrations project it was a multi-faceted one toshowcase; (1) an appropriate water treatment method, (2) an affordable method of
construction, (3) a participatory planning and management process and, (4) a cost reduction
and cost sharing mechanism. This paper briefly deals with all these demonstrative aspects ofthe project.

Community Mobilization
Tropeang Chork Community has a total of 106 households and a population of 527. The
average monthly income of a household is around 200,000 Riel (≈ 50 USD). People are-40-

engaged in casual work, small businesses, motorcycle taxi operation and rice cultivation. Lackof water supply and sanitation facilities are the most acute problems that the community face.
During the rainy season, most people (59%) harvest rainwater from the roofs and some others(24%) utilize pond water for domestic purposes. Others extract ground water using a handpump installed by a project funded by JICA. During the dry season, 96% of the households
depend on water vendors for drinking water. The price of water is about 8,000 Riel (2USD)/m3 and the source of that water is unknown. The majority of households utilize water
brought from a pond for domestic purposes during the dry season. This pond is located about
1.5 km from the community. Carrying water from the pond to households is a burden,
especially for men. Water for about 80% of the households is brought by men using pushcarts or motorcycles. It takes about 1 hour to fetch water from the pond and bring to thecommunity.
Therefore, bringing safer water closer to the community was the major idea of thedemonstration project. With this idea, a treatment plant to treat rainwater harvested in the new
pond and a distribution system was envisaged. The newly excavated pond is located within
the community. Since it is newly excavated, the harvested water in the pond was very muddy.
Mr. Khatri, the project implementer, could successfully negotiate with the community and the
SEA-UEMA Project for a collaborative intervention to treat and distribute water obtained
from this pond. The SEA-UEMA Project agreed to provide financial contribution of 10,450
USD and technical support (through an environmental engineering expert, environmental
management expert and a gender expert) and the community agreed to contribute land to
install the treatment plant and labor for construction. The community also agreed to install a
distribution pipe system from the treated water storage tank to individual households, once thetreatment system is completed. The project implementer could also obtain some financial
contributions (3,050 USD) from several NGOs, another community development project anda trust fund.
The main activity of the project was designing and construction of the water treatment plant.
The team of change agents faced three challenges in designing the system, (1) How to treat
harvested rainwater which is contaminated with coli-form and with high turbidity, (2) How todesign and construct a treatment system within the available budget, (3) How to design atreatment system which is simple for the community to manage by itself.
The initial design showed that cost of construction using Reinforced Cement Concrete (RCC)
will greatly exceed the available budget. Therefore, it was decided to use Ferro-cement
technology to reduce the cost of construction. Initial calculations revealed that the cost of
construction can be reduced by 50% if ferro-cement is used. Since there was no precedence
existed to explain this idea to the community, a scale model of the designed system was built
involving some community members. Technical assistance for this was obtained from a local
NGO that had some experience in Ferro-cement construction. This was useful for thecommunity members involved in the project to understand how the chambers for coagulationflocculation-sedimentation and filtration work, and also getting hands-on training on Ferrocement construction. The model was also useful to build confidence among the community
members. There was some pessimism at this stage about the ability of the system to treat the
muddy water obtained from the pond into clean water. A workshop was conducted involving
both men and women to introduce them how the system works and its potential to reduce theirburdens. Since women are the major handlers of water at the households and men are mostly-41-responsible for fetching water, participation of both genders in the action planning process
was very important.
Application of Ferro-Cement Technology for Components of the Water Treatment Plant
The water treatment system consists of the components as shown in the diagram below.

Coagulation, Flocculation and Sedimentation Tank: Raw water with silt is pumped fromthe pond to this tank through a storage tank. In this tank, water is passed through a coiled
perforated pipe that runs vertically up and down along the wall of the tank. A coagulant (alum- Al2SO4) is added to raw water in this pipe to enable the flocculation process which works on
the principles of 'hydraulic mixing'. Once passed through the pipe, water is retained in thistank for few hours allowing the sediments to settle down at the bottom. The tank was madeout of Ferro-cement using a cylindrical shape with the dimensions of 4.0m in diameter, 2.0m
in height with 8cm in thickness. This was placed on a 0.7m high base to create a gravitational
flow.
Aerator: Air affects water chemically and physically. This fact was explained to thecommunity and used in the project. The water coming from the sedimentation tank was set topass through a set of perforated pipes and drip into the Filtration tank while aerating water inthe process.
Slow Sand Filter and Clear Well: The aerated water passes through a slow sand filter toremove the remaining particles in water. Slow sand filter is a simpler technology that thecommunity can easily manage by replacing upper layer of sand from time to time instead of
backwashing sand that is technically more sophisticated. Additionally, the design of the filter
has provision to maintain a continuous layer of water on top of the sand layer to prevent any
growth of algae on sand. The filtered water is collected in a clear well where Chlorine is-42-added to destroy any remaining bacteria. The clear well also serves as the ground storage tankbefore pumping to the over-head tank for distribution. The filter chamber and clear water
storage chamber was attached in a single tank to economize on the cost. This was also
constructed using Ferro-cement with the dimensions of 5.0m in diameter, 2.0m in height and
8cm thickness.
Overhead Tank: Water from the Clearwater storage tank is pumped to the overhead tank.
This tank serves as the hydraulic head provider for water distribution through a gravity system.
A RCC structure having 5.0m height was constructed to place a heavy duty PVC storage tank.
This is the only major element of the system that did not use Ferro-cement technology. There
was no expertise available in Cambodia to construct an overhead tank using Ferro-cement.
Water Meter and Distribution Point: This part is installed at the bottom of the overheadtank to distribute water and measure the quantity of water sold to the consumers.

Capacity Building
A series of trainings/workshops were conducted involving both men and women of thecommunity, throughout the participatory planning and implementation process. This included;• Visit to community water supply projects in Kandal Province (20 people - 3 Female)• Training on Ferro-cement construction (7 people, all male)• Training for the maintenance team (4 people, all male) on Jar Test, use of alum and
Chlorine• Training on maintaining the sedimentation tank and slow sand filter• Training on user charge collection and accounting to financial management committee (4people - 2 Male, 2 Female)In addition to the above, 10 community meetings were held during the community action
planning process with average participation of 44 females and 60 males. These were useful incollective capacity building for shared decision making.
Output Results
The total water demand of the community is 28.6 Cum/day as per the baseline survey. The
water treatment plant was designed to produce 30 Cum/day but it yielded only 25 Cum/day at
the initial period of operation. This was attributed to the high turbidity level of the input water.
Water quality tests on input and output water showed following results.

The follow-up meeting also revealed some other outcome results. The close location of thesystem to the community lessened the workload of both men and women. Although the shareof workload has not changed among men and women after the project since they still have tocarry water to homes, their burden has reduced due to the closer location of the new source ofwater. This will further reduce when the community accumulates enough funds from water
vending and savings to install community stand points first, and individual household
connections later. The community collectively decided to fix the water tariff at USD 0.5/Cum.
This has reduced the financial burden of the households, since they used to pay more than
USD 2/Cum for water brought to the community by a vending truck. As a demonstration
project the most significant outcome result of the project is the revelation of social capital
available in the community to invest in a community enterprise. People’s voluntary
participation in planning and implementing this community project and their contribution of apiece of community owned land (4,200 sq m.) for the water treatment plant and labor forconstruction indicated their willingness to invest their social capital. If these contributions arevalued in monetary terms, their share is about 80% of the total project cost. However, it was
the financial contribution of the SEA-UEMA Project and the interventions by change agentsto mobilize the community that trigged the outflow of this social capital.

-44-

Sustainability of the System and Challenges
Sustainability is a critical issue in any project intervention. Sustainability concerns alreadyexit in this project after nearly two years of operation. The output level has come down to 15
Cum, that is 50% of the designed capacity. There are two interconnected reasons behind this.
Firstly, the high turbidity of input water has clogged both flocculation coil and the slow sandfilter. Secondly, the maintenance team has failed to regularly maintain the system due to theirlivelihood related priorities. Especially during the farming season they have not been able toattend to the maintenance work. Moreover, water is not a scarce resource during the rainyseason. People can rely on rainwater harvested from their roofs. This has led to reduced
demand during the rainy season, which has disappointed the project management team.
People in the community are also loosing the confidence by seeing the gradual reducing of
output efficiency of the system. They perceive that the system cannot meet the total water
demand of the community. Therefore, they are reluctant to contribute to the community
saving fund to install the water distribution system. In order to address these problems, anadditional tank for coagulation-flocculation-sedimentation is being constructed using further
funding support (USD 11,570) from the SEA-UEMA Project. This tank uses a baffle system
for flocculation, instead of the previously used coil system. This decision was taken based on
the lessons learnt by monitoring the functioning of the first sedimentation tank. It is also
expected to reinstall the slow sand filter using new media to increase its efficiency. Alum isperiodically added to the raw water pond to reduce the turbidity of input water. Banks of thepond were consolidated to prevent erosion of the banks and silting water in the pond. Trials
are being carried out to identify suitable aquatic plants and ground covers that can reduce thesilting of water in the pond. The biggest challenge still remain is the generation of adequate
funds to construct the distribution system. Until then, people have to come to the treatment
plant to buy water.

Abstract
Developing countries in Asia are threatened by environmental pollution due to the lack ofwaste treatment facilities. Most wastewater treatment technologies are known as being costly
and not affordable by the municipalities and the small scale polluting industries. When land isavailable, phytotechnology is a promising and cost effective approach for domestic andindustrial wastewater treatment. In addition, phytotechnology can be potentially used forrehabilitating degraded environment. This paper briefly discusses about the applications, ideas,
and future perspectives of phytotechnology as an appropriate tools in promoting sustainable
water sanitation and conservation in Asian countries.
Keywords: phytotechnology, application, advantages
Introduction
The tropical region in Asia is mostly occupied by low to middle income countries, with rapid
industrial and urban development. As a consequence, environmental pollution has often
occured due to insufficient control technology. For example, Indonesia should face severe
environmental pollution, particularly in Java, Sumatera, Kalimantan, Sulawesi, Lombok, andPapua, where urban, industrial and mining wastes are not treated sufficiently. The nation wide
Clean River Program (PROKASIH), which was implemented by the Environmental Impact
Management Agency (BAPEDAL) during the 1990s (Trihadiningrum, Verheyen and De
Pauw, 1997), did not show significant surface water quality improvement.
In addition to the above information, Malaysia has faced rapid urbanization and industrial
developments since 1991. The inland water is polluted due to point sources and non-point
sources of pollution. Point sources that have been identified include sewage treatment plants,
manufacturing and agro-based industries and animal farms. Non-point sources are mainly
diffused ones such as agricultural activities and surface runoffs. The storm water was also
believed to contribute significant amount of nutrients, heavy metals, oil and grease to thesurface water.
Tropical region is characterized by whole year solar energy resource, which can betransformed to biomass through efficient plant metabolism. This condition is beneficial for
supporting plant based wastewater treatment technology, which is known as cost effective andpublicly accepted. In the US such a technology is widely applied as an acceptable clean-up
technology for polluted sites.

The term phytotechnology describes the application of science and engineering to examine
environmental problems and provide solutions involving plants. This term promotes a broader
understanding of the importance of plants and their beneficial role within both societal andnatural systems. A central component of phytotechnological concept is the use of plants asliving technology that provides services in solving environmental problems. The term
phytoremediation is used to describe the plants processes in absorption, extraction, conversion
and releasing for contaminants from one medium to another (Mangkoedihardjo, 2007).
Phytotechnology has been introduced and developed for the treatment of urban runoff,
domestic and industrial wastewater, and remediation of polluted soil since the last three
decades. Constructed wetlands and phytoremediation are examples of the most commonly
applied technologies for removal of pollutants in water and soil. Phytotechnology is not only
known as cost effective means for water quality improvement and stormwater control, butalso provides aesthetics and wild life habitat (USEPA, 1993).
This paper briefly discusses about the applications, research experience in persistent pollutant
removal, ideas, and future perspectives of phytotechnology as appropriate natural tools inpromoting sustainable water sanitation and conservation.
Mechanisms, advantages and disadvantages of phytotechnology
In phytotechnology, the plants act as solar-powered pump-and treat systems as they take upwater soluble contaminants through their roots, and transport them through various planttissues, where they can be metabolized or volatilized (Doty et al., 2007). Former researchers
have identified various tolerant plants which are able to significantly reduce organic andinorganic pollutants in the waste water and in the polluted soils and surface waters. According
to Kramer (2005) and Doty et al. (2007), there are several mechanisms of water and soil
environment improvement using phytotechnology:‐ Phytostabilization: a mechanism which is used more to providing a vegetation coverfor heavily contaminated soils, thus preventing wind and water erosion. Plants suitablefor phytostabilization develop an extensive root system, provide soil cover, possess
tolerance to contaminants, and ideally immobillize the contaminants in the root system‐ Phytoextraction: a mechanism, where pollutant tolerant plants concentrate andaccumulate soil or water contaminants in their tissues. At the end of the growth period,
the contaminant enriched plants are generally harvested and dumped; or dried andincinerated. Heat from the incineration is used for energy generation‐ Phytovolatilisation: a mechanisms, where plants transport soluble pollutants to theabove ground tissues and volatilize it to the atmosphere.
‐ Phytodegradation: a mechanism where plants, associated with aquatic or soil
microorganisms, biodegrade organic pollutants
Phytotechnology is an accepted method for it’s advantages as a cost effective technology,
publicly accepted, and does not altered soil matrix. However, there are several limitations of
this technology, such as:• site specific properties for optimum plant growth (soil texture, pH, salinity, type ofpollutants)• limited uptake capability of the plants• time consuming-47-

Applications of phytotechnology
Phytotechnology has been applied for stormwater remediation in Putrajaya, Malaysia’s newFederal Government Administrative Centre. Central to this city is the 400 hectare man-madelake created by damming of Chua and Bisa rivers. The Putrajaya Wetland was constructed in
1997-1998. Construction and operation of the wetland is aimed to create a self-sustaining andbalanced lake ecosystem and to ensure the lake’s water quality complies with standard set by
Putrajaya Authority and suitable for body contact recreational activities. The wetlands are
strategically located to act as buffer to the Putrajaya Lake which drains a catchment area of
50.9 km2. Involving an area of 197 hectares and 12.3 million wetland plants, this wetland is
one of the largest fully constructed freshwater wetlands in the tropics (Huat, 2002).
When land is available, application of phytotechnology is also considered to be appropriate
for treating small scale pollutant sources. For example, domestic wastewater, where sewage
treatment facility does not exist, can be treated using phytotechnology. This technology isalso appropriate for treating industrial wastewater, which contains biodegradable organics,
such as slaughter house, seafood, and tofu and sugar manufacturing industries (e.g. Sohsalamand Sirianuntapiboon, 2008; Sari, 1999).
The tropical Asian countries are famous for their traditional batik and waven cloth.
Unfortunately, these products, in Indonesia in particular, are mostly manufactured in homescale industries, where wastewater treatment facility is not provided. As a consequence,
coloured waste water with high COD and suspended solids levels is discharged directly into
the environment with very limited treatment. The following discussion is focused on a
successful wetland technology application for domestic wastewater treatment in Indonesia,
and present research work on the use of plants for the treatment of waste water from a small
scale yarn dyeing industry.
Wetland technology for domestic wastewater treatment
Domestic waste water from a community in Tlogo Mas Village, which is located in Malang
town, East Java Province, Indonesia, was successfully treated using vertical flow subsurface
system (SSF) constructed wetland, which was designed by Mr. Agus Gunarto. One hundred
and ten houses have been connected to this wetland facility since 1990. The wetland facility
consists of 3 primary reactors (or floating tanks) using water hyacinths (Eicchornia crassipes),and 3 secondary reactors (or subsurface tanks) using cattails (Typha latifolia) (Figure 1). The
wetland facility has a depth of 1,5 m. Daily wastewater intake is 50 m3, and detention time ineach tank is 12 hours. Peak time occurs at 06.00 to 08.00 am, and at 04.00 to 07.00 pm.
This SSF wetland worked with a maximum BOD loading rate of 70 kg/ha.day. A successful
vertical flow SSF wetland can remove organic matter, total N, and total P of >96%, 36%, and
63% respectively (Fitriarini, 2002). With an average medium level of Indonesian domestic
wastewater characteristic of BOD of 220 mg/L, total N of 40 mg/L, and total P of 8 mg/L
(Djajadiningrat, 1992), this wetland system could produce good quality of effluent. The areaof the old wetland was planned to be extended to 24 m x 30 m, with the addition of floating
and subsurface tanks.

Study on wetland technology for treating waste water from yarn dyeing industry
Batch bioreactors were prepared in a green house for testing the potential of water lettuce,water hyacinth and Canna sp in removing persistent pollutants of the yarn dyeing wastewater,collected from Sidoarjo town, East Java Province, Indonesia. The wastewater had black
colour and high pH, COD, and total suspended solid (TSS) values (Table 2), which exceed thequality standards. This waste water is usually discharged to the surface water without any
treatment. The Range Finding Tests for determining the plant tolerance to the wastewater,
resulted in much low levels of COD, BOD, and TSS levels, in which the plants could growsatisfactorily (Table 1).

Application of the three plant species in the batch reactors within 30 day detention time
showed significant removal efficiencies of organic matter and TSS, with the highest values in
Canna reactor (Table 2). Yet the effluents did not meet the waste water quality standards.
Moreover, none of these plants showed tolerance in the original waste water. Therefore,
phytotreatment technology can only be applied in the final or tertiary treatment stage in such akind of waste water, which contains recalcitrants. Due to the high COD levels, a combined
four compartment anaerobic baffled reactor (ABR) and wetland system are thought to beappropriate for treating the waste water, before it enters the plant reactor or wetland (Figure 2).
Selection of the ABR system is based on the cost effective and easy operation andmaintenance considerations (Bell and Buckley, 2003). This system can be applied as acommunal wastewater treatment facility from similar industries.

Discussion
The above mentioned case studies show that phytotechnology can be applied for communal
treatment of domestic and small scale industrial waste water. However, this technology may
be suitable for supporting a secondary treatment facility in the domestic waste water treatment,
but is more suitable to be applied as a tertiary treatment facility in the industrial waste water
treatment plant. Table 4 summarizes the comparison of the application of phytotechnology indomestic and small scale industrial waste water treatment.

Future perspectives of phytotechnology
As plants have been used as natural cover blanket of the earth, its application is not limited
only for remediating polluted water and soils, but also for stabilizing eroded slopes. Studies
on the remediation of degraded water, soil, and land using plants (lately known asbioengineering) have been extensively implemented and applied. Vetiver grass (Vetiveria
zizanioides, or Chrysopogon zizainoides), a super-absorbent and deep rooted perennial grass,could be used for landfill rehabilitation, erosion and leachate control in particular (Truong andStone 1996). Because of the high tolerance of this grass species to high acidity, alkalinity,
heavy metal levels, this grass species is also recommended for the rehabilitation of mining
areas (Truong, 1999; Grimshaw). Therefore, phytotechnology is not merely applicable forwater sanitation, but can also be also involved more to water conservation.
The harvested plants from the application of phytotechnology, however, needs additional
measure in a completed treatment cycle. Particular cultivation treatment, such as cutting andharvesting of the plants are needed for maintaining the pollutant removal efficiency. The
plants from nutrient, greywater and blackwater treatment facilities may not pose a problem fordisposal. These nutrient accumulating plants may be used for composting and for energy
production. In many cases, the harvested plants are dried and incinerated. The heat released-51-

from the incineration is used for energy generation. However, plants from remediated sites,
which are polluted by hazardous waste, are generally suspected to contain significant amountof hazardous pollutants and need careful disposal measures (Kramer, 2005). Incineration of
the plants may be costly, and is believed to become hazardous gas and ash emmission sources.
Fermentation technology for biogas production is one of the solutions of these problems. In
addition to this bioenergy production alternative, biodiesel can be produced from rich oil seedproducing plants (e.g. sunflower and Jatropha curcas), when they are used for environmental
remediation. A conceptual scheme of energy transformation and phytotechnology is shown in
Figure 3.
Future R&D activities in phytoremediation are multidisciplinary, and may involve various
expertises, such as environmental engineering, hydrology, environmental chemistry, plant
ecology and physiology, microbiology, and molecular biology. Current research activities inwestern countries are focused on genetically modifed organisms (GMO) for inventing tolerant
plant species to particular environmental pollutants with high removal efficiencies. A numberof research works are done today to seek bioenergy production feasibilities from the harvested
plants.
To end, phytotechnology is a promising, cost effective and environmentally sound technology
for water sanitation and conservation. The remarkable capabilities of the plants in waterpollutant removal and rehabilitation of degraded environment, together with the biomass andenergy recovery potentials, provide a nature-based technology which supports sustainable
development program in our countries.

Abstract
As part of the Japan-China water environment partnership project agreed on between theleaders of the both countries, the Japanese Ministry of the Environment started a four-year
rural area decentralized wastewater treatment model project in 2008. This project is intended
to install model treatment facilities in some regions with typical requirements or conditions
based on the experience of the both countries, and to work on the penetration of these systems
in the future. In 2008, treatment systems were installed in Taizhou, Jiangsu and in mountainareas of Chongqing, in light of the conditions of these areas. A gravel contact aeration system
and an constructed wetland system were selected for Taizhou and Chongqing, respectively. A
gravel contact aeration system based on Japanese technologies and a constructed wetland
system based on Chinese technologies were used. Both countries will further study theoperation of these treatment systems to promote their penetration in the future.

Introduction
In China, the amount of domestic wastewater has accounted for a larger percentage of thetotal amount of wastewater than that of industrial wastewater since 1999, and the gap has
been widening year by year. Therefore, promoting domestic wastewater measures has been amajor issue. To cope with this situation, heavy investments have been made in thedevelopment of sewage systems in urban areas, where 1,178 sewage treatment plants havebeen built and operated across the country by the end of 2007. This pushed up the sewage
treatment rate to 60 percent. A total of 472 out of the 1,178 sewage treatment plants were built
between 2006 and 2007, and it is believed that the development of sewage systems in urban
areas will further pick up speed in the future. Thus, domestic wastewater measures in urban
areas have almost been put into place, but rural areas, with a larger population than urban
areas, are far behind urban areas in these measures.
Rural areas, which are less densely populated than urban areas, require a decentralized sewage
treatment system to cover a relatively highly populated area rather than a large-scalecentralized sewage treatment system as seen in urban areas. In view of the economic situationof rural areas, systems that have low construction, maintenance, and operation costs are
required.
In Japan, the sewage treatment rates in Tokyo, Osaka, and other urban areas with a populationof over one million have reached almost 100 percent, but those in local city areas with a-54-

population of less than 50,000 still remain around 65 percent. In these local city areas,
decentralized treatment systems that have low construction, maintenance, and operation costs
have been introduced on a trial basis. Under these circumstances, those involved in the JapanChina water environment partnership project started to work to build decentralized domestic
wastewater treatment systems in rural areas in China based on their respective experience, aspart of the project.
Necessity of Domestic Wastewater Treatment in Rural Areas in China
There is less information available on domestic wastewater discharge conditions in rural areas
than on those in urban areas, and there are many unknowns. Liu, et al. estimated the nitrogenflow in rural areas by supplementing the existing statistical data with field work surveys, andstudied the effects of human life on the flow1). They estimated the nitrogen flow in Taoyuan,
Hunan and Taihe, Jiangxi located in the middle to lower reach of the Chang Jiang River. Both
districts are rice-producing rural areas, but Taoyuan has introduced more machinery into its
agriculture. In rural areas in China, raw sewage has been recycled as fertilizer over a longtime2). The recycle rates of raw sewage in terms of nitrogen in Taoyuan and Taihe were 27
percent and 67 percent, respectively. In Taoyuan, about 70 percent of lavatories have been
converted into flush toilets and this shows the gradual development of sewage systems, but
sewage treatment has lagged behind the development of sewage systems. In Taihe, on theother hand, the recycle rate of raw sewage is high, and flush toilets account for only about 30
percent of all lavatories because vault toilets are widely used, and people there are lesssatisfied with their toilet conditions than those in Taoyuan. In Taoyuan, chemical fertilizers
account for 70 percent of nitrogen put on agricultural land, which reflects the advanced
mechanization of agriculture. These study results suggest that the recycle rates of raw sewage
in rural areas will be lowered following the increasing mechanization of agriculture andimprovement in people’s living standards, and the necessity of domestic wastewater treatment
will be increased. The necessity of domestic wastewater treatment will be further increased at
an accelerated speed by new agricultural village construction projects and other urbanization
policies. Thus, construction of domestic wastewater treatment systems in rural areas is anurgent issue to be addressed for the improvement of hygienic conditions in rural areas and the
reduction of effects on watersheds.
Rural Area Decentralized Wastewater Treatment Model Project
Under these circumstances in rural areas, the Japanese and Chinese ministers of theenvironment signed the “Memorandum on a Joint Rural Area Decentralized Wastewater
Treatment Model Project” on May 8, 2008. Following the conclusion of this memorandum,
the Japanese Ministry of Environment started the project by working on the installation ofmodel decentralized wastewater treatment facilities in China and the following items:(1) Study the reduction of water pollutants and what water environment management shouldbei) Analyze the current situation and issues of the model project areasii) Collect and analyze basic information necessary to introduce decentralized domestic
wastewater treatment technologiesiii) Work on the formulation of policies or laws and regulations on decentralized domestic
wastewater treatment-55-

(2) Introduce decentralized domestic wastewater treatment technologiesi) Introduce decentralized wastewater treatment technologiesii) Determine the effects of decentralized wastewater treatment technologies(3) Help those involved in the Chinese government with capacity building and enhance policy
dialogue(4) International seminar on theory and practice on total pollutant amount control in Japan and
China
Based on the installation of model decentralized wastewater treatment facilities in China, thisproject will promote the penetration of these facilities in China from 2008 to 2011.
Installation of Model Decentralized Wastewater Treatment Facilities
Overview of Model Installation Areas
In 2008, model facilities were installed in the Chang Jiang River basin, or in Taizhou, Jiangsu,
which has attracted many industrial complexes and been urbanized because of the resultant
economic growth, and in Zhong and Wanzhou, Chongqing, located in the upper reach of theThree Gorges Dam. In Taizhou, new agricultural village construction has promoted thereadjustment of land for industrial use, agricultural land, and residential land, and residences,which had been scattered over agricultural land before, have now formed villages of hundred
to several hundred families. Thus, wastewater treatment must be provided for each of thesevillages. These villages basically use flush toilets, but conventional treatment facilities, whichwere based on septic tanks installed in individual households, do not provide satisfactorytreatment of wastewater. In this area, creeks run around the villages like the mesh of a net, andwastewater from the villages is discharged into the creeks. Thus, insufficient treatment ofwastewater may affect the surrounding water environment. In addition, economic growth has
increased the convenience of the land to make it difficult to acquire a large land lot for awastewater treatment plant, which makes it inevitable that wastewater plants will be installednear residences.
On the other hand, Zhong and Wanzhou of Chongqing are comprised of purely agricultural,
mountain villages with large, terraced paddy fields. In these mountain areas located in theupper reach of the Three Gorges Dam, villages of several thousand people are scattered, andwastewater treatment must be provided for each of these villages. Since the incomes of thosein the purely agricultural villages are not so high, construction, maintenance, and operation
cost requirements for wastewater treatment plants in these areas are severe. However, arelatively large land lot can be secured for a wastewater treatment plant, though it is difficult
to secure a flat land lot in the hilly areas.
Selection of Treatment Systems
In Taizhou, compact and high-level treatment technologies should be used because of the
difficulty of acquiring large land lots, and the proximity of treatment plants to residences
requires measures against odor to be taken. Considering the future spread of these treatment
plants, construction, maintenance, and operation costs as well as the production of sludge, themajor problem in operating treatment plants, must be kept low. In view of these requirements,a gravel contact aeration system, which has been increasingly used as a decentralized-56-

treatment facility in Japan, was introduced in Taizhou. A treatment facility of this system istopped with soil to produce fewer odors. Based on a biofilm process, this system produces
less sludge than an activated sludge process. The target quality of treated water is a CODcr of
60 mg/L or lower, a BOD5 of 20 mg/L or lower, an SS level of 20 mg/l or lower, ammonia
nitrogen of 15 mg/L or lower, and a coli form bacteria count of 104 MPN/L or lower. Thisquality of water complies with Class 1-B of the discharge standard of pollutants for municipal
wastewater treatment plant in China. The target maintenance and operation cost was set at
0.09 US$ per m3 of sewage.
In Chongqing, to keep treatment plant construction, maintenance, and operation costs low, atreatment system based on a constructed wetland was applied. To secure stable operation of aconstructed wetland over a long time, a preliminary aeration process was combined. A generalcontact aeration system was adopted for preliminary aeration to reduce the production ofsludge, and a plastic filter medium commercially available in China was selected as a contact
medium. The target quality of treated water is a CODcr of 100 mg/L or lower, a BOD5 of 30
mg/L or lower, an SS level of 30 mg/l or lower, and ammonia nitrogen of 25 mg/L or lower.
This quality of water complies with Class 2 of the discharge standard of pollutants formunicipal wastewater treatment plant in China. Considering the economic conditions in theregion, the target maintenance and operation cost was set at 0.05 US$ per m3 of sewage.
Because Japan has no experience in domestic wastewater treatment using a constructedwetland, a constructed wetland designed by China with a good track record was combinedwith this wetland.

Overview and Features of Treatment Systems
Gravel Contact Aeration System
This system consists mainly of a settling and sludge storage tank, a contact aeration tank, anda settling tank, and uses gravel as a contact medium. Figure 1 shows the treatment flow.
Sludge produced by treatment is stored in the settling and sludge storage tank, and must be
removed once or twice a year. The removed sludge is recycled as a liquid fertilizer. The
sludge production is about 15 to 25 percent of that for a commonly used standard activated-57-sludge process or oxidation ditch process. Because the treatment facility is topped with soil, atreatment plant may be installed in a corner of a residential area in Japan, and so not so muchconsideration needs to be given to measures against odor. In Taizhou, a facility with atreatment capacity of 150 m3/day and another facility with a treatment capacity of 40 m3/day
were installed. While the facility with a capacity of 150 m3/day is of reinforced concrete, thefacility with a capacity of 40 m3/day uses a liner sheet, concrete blocks, and other building
materials rather than concrete building frames to keep the construction cost low. This
construction method cannot be used for a large facility, but can keep the construction cost low
for an ultrasmall facility. Figure 2 shows the construction status in Japan.

Figure 2. The construction status of the low cost facility.

Preliminary Contact Aeration—Constructed Wetland System
As shown in Figure 2, depicting the treatment flow, this system consists mainly of a settlingand sludge storage tank, a preliminary contact aeration tank, a sedimentation tank, and an
constructed wetland. According to the guidelines in China, wastewater put to a constructedwetland must not contain a CODcr of greater than 200 mg/L, a BOD5 of greater than 70
mg/L, an SS level of greater than 40 mg/l, and ammonia nitrogen of greater than 30 mg/L.
Since this quality level cannot be achieved by settling separation alone, a preliminary aeration
process must be combined. The aeration time was set at four hours, but it must be optimized
through actual operations because the length of the aeration time greatly influences themaintenance and operation cost. Produced sludge can be stored in the sedimentation
separation tank for up to about one year.

Future Prospects and Issues
Model treatment technologies were selected and installed in Taizhou and Chongqing in lightof the situations of these regions. In Taizhou, where the readjustment of residential land has
been promoted by new agricultural village construction, a compact, simple treatment flow
system was selected. Not a pre-fabricated treatment system popular in Japan but a system thatcan be constructed in China was used. In Chongqing, a constructed wetland system wasselected in light of the economic conditions of the rural areas and the relatively warm, humid
climate. However, to allow stable operation of a constructed wetland over a long time,
preliminary biological treatment was combined. In the future, Japan and China will jointly
study the operation of the model treatment systems to develop them into more advanced,
versatile systems.
This time, the reduction of sludge production was a criterion for selecting these treatment
systems. However, because the production of sludge cannot be avoided, treatment or disposalof sludge must be further studied with an eye toward the future. Basically, produced sludge
should be recycled as fertilizer for use in these rural areas, and how it should be recycled must
be studied also from the perspective of farmers. Especially, whether to recycle sludge as
liquid fertilizer or dry fertilizer, which decides whether to add a sludge drying process or
influences the design of a treatment system in other ways, must be clarified in view of theform of agriculture in that region.
This model project has been promoted based on adequate discussions between the Japaneseand Chinese governments and engineers. Therefore, adaptable cooperation of China can be
expected, and the project will be further promoted with the experience of the both countries.
Since these decentralized domestic wastewater treatment systems are also important in othercountries, improvements both in tangible and intangible aspects for the development ofadaptable systems must be sought, and further efforts must be made to develop the JapanChina water environment partnership project into foreign aid based on cooperation between
the both countries.

Abstract
This study analyzed Rural Water Supply and Sanitation (RWSS) quality improvement under
Water and Sanitation for Low Income Communities (WSLIC II) project in Jorong Kampung
Baru, Solok district, West Sumatra. The paper explores people participation in the projectwith emphasized on equal participation between men and women in decision-making process,
implementation, operation and maintenance, monitoring and evaluation. In decision-making
process, men more actively participate and they attended the meeting more frequently than
women. Women also participate in the project construction as well as men as unpaid labors.
However, women did not get any knowledge about the schemes during the project
construction or trainings. Women use the facilities more often than men but lack of generalknowledge on the schemes make the women unable to do maintenance tasks. Men and womenparticipation in monitoring and evaluation was very low because most of them were not
involved in evaluation activities, besides they did not have initiative to report and discuss thesolutions concerning damage or destruction of facilities. The sustainability of the project in
the next five or ten years is threatened because women were not effectively involved in the
project. Therefore, involving both men and women effectively in the project phases need tobe emphasized and implemented in the achievement of project sustainability.
Keywords: people’s participation, WSLIC II, rural water supply project.
Introduction
Access of rural communities to sanitation in Indonesia is reported 52%, however the real
number might be lower since the data do not specify whether the existing sanitation facilities
meet the minimum standard for sanitation, whether the facilities in good condition and being
used by the communities or not (Robinson, A., 2005). Many efforts related to provision ofclean drinking water and sanitation has been implemented by the Indonesian government
which is supported by national and international agencies, NGOs and other institutions.
However, the performance of water supply and sanitation sector in Indonesia is lower
compared to other countries in South East Asia (WHO – UNICEF, 2004 cited in proposal of
National Program for Community Water Supply and Sanitation Services). A study by Sara
and Katz (1997) on rural water supply sustainability in relation to project rules in someprojects in some countries, reported that Indonesia has the lowest score in physical condition,
operation and maintenance, consumer satisfaction, financial management and willingness tosustain the system. Some of the problems are low quality of construction that cause thedecrease on water flow and lack of people knowledge to cope with destruction. Women as the-61-main beneficiaries prefer to use old water sources because they are not satisfy with the newwater facilities. As the consequence, community particularly women do not have sense ofownership to the system which cause unwillingness to sustain the system.
The objective of this paper is to explore people’s participation in rural water supply project byanalyzing both men and women participation as the main water users. In this context, people
participation means that involving women as well as men This paper would address thequestion, whether women are involved as well as men, if yes whether women exclusion or
inclusion influence the sustainability of the project. This study employs five techniques indata collection namely participant observation, in depth interview, focus group discussion,
recording of oral history, survey and review of secondary data.
Water and Sanitation for Low Income Communities (WSLIC) project in Jorong
Kampung Baru, Nagari Gantung Ciri
WSLIC Project
WSLIC is a single sector water and sanitation project. The project is funded by World Bank
and AusAid. The funds are channeled through four lines agencies. WSLIC is a government
project where the Ministry of Health is primarily responsible for the project. WSLIC project ismainly concerned to the low-income communities in the rural area through community
empowerment approach in decision-making process, implementation, operation andmaintenance and for its sustainability.
Study Area
Jorong Kampung Baru is located in Solok District, West Sumatra. Based on the secondary
data collected in 2002, there are 185 households living in this area. Educational backgroundof the people is very poor; most of them are graduated from elementary school (84%). The
majority of the people are farmers. More than half of the community (52%) is categorized aspoor based on welfare classification conducted by Village Implementation Team of the
project in 2002. Jorong Kampung Baru was chosen based on the proposals to the WSLIC II
committee in 2002. The consideration is related to the diarrhea disease, social and economic
condition of the community. In fact, water sources are available, but it is difficult to accessand there was not any effort to improve water accessibility.
Water and sanitation in Jorong Kampung Baru
Water sources in Jorong Kampung Baru are available in a great amount. The water sources
are spring, river, stream, unprotected well. However, the location of springs is quiet far fromthe settlements. They are about 2 km from the settlement. People have to walk through rocky
path for collecting water. Nevertheless, the water depends on the season. The quality of water
during dry season is better than in rainy season. However, the amount of water during dry
season is not enough to fulfill the needs, water shortage mostly happened during this period.
Moreover, most of people do not have well in their house because it is hard to find water
sources although they have already dug the well. People usually fetch water from the housethat has well for about 500 m to 1 km from their house. They use the water only for drinking.
Other household needs such as for bathing, washing the dishes and washing clothes are doneon streams that flow near their houses.

Most of the people in Jorong Kampung Baru do not have appropriate sanitation in their house.
They usually defecate in stream or pond near their house and also from the dry agriculturallands (ladang). People are not used to defecate by using latrine. They think that it is dirty and
it is not proper. The general condition of sanitation in Kampung Baru described as follows(Table 1).

Both, bad latrine and lack of clean water supply in this area has caused diseases such as
diarrhea and skin disease especially during dry season. Due to lack of facilities, most of thepeople have experience this bad and unhealthy habits for many years.
Referring to the MPA-PHAST (2002) conducted by the Community Facilitator Team (CFT),
there were two options for water source used in this project namely river and spring. Spring ischosen as the source of water considering some factors such as physical water quality, sourceof contaminant, capacity of water, distance from settlement, flowing system. Physical water
quality is based on four indicators: smell, taste, turbidity and color. Debit of the spring is 2
lit/sec during dry season. The seasonal fluctuation is relatively constant in dry season andtends to increase in rainy season. Technical options of the project are completed with water
catchments, reservoir and pressure releasing chamber.
People participation in rural water supply and sanitation projectCommunity participation is one of the important factors in the achievement of goals of any
development activities. People participation is known as the most effective way in promoting
and achieving sustainability of rural development projects, particularly in developing
countries (Livingstone and McPherson, 1993).
People participation in project initiation and decision making process
WSLIC II is a development project, which applies participatory approach. All phases of the
project are intended to encourage community participation. One of the facts showing the
involvement of people in the project is the process of proposal formulation. Each Jorong was
excited in preparing the proposal for the WSLIC project.

Figure 1. Frequency of People Attendance in Meeting
Socio cultural plays important roles in decision-making process. Related to its socio cultural
system, the people in Kampung Baru usually discuss any problems for the improvement of
their kampung. This activity is known as musyawarah. However, it is usually done by men.
Women are rarely take part in musyawarah because the people think that women responsible
only to take care children and household’s activities, such as cooking, washing, cleaning thehouse and sometimes help their husband in ladang (Figure 1). The absence of women in a
meeting is not merely caused by the objection of men to their involvement or hesitation andfear (Prokopy, L.S 2004). In this study, women mainly claimed that their absence from themeeting is due to their roles as wife and mother. Moreover, the meeting is usually held in theevening that makes women reluctant to attend the meeting.
People participation in project construction
In areas with a different gender culture, men do the works such as digging while women andchildren do transporting, catering or organizing other support activities (Abeywardena, 1977;
Jaeger and Mattson, 1989; Mc eachem et al., 1983; NCU, 1991., cited in Wijk, 1998). A
different situation is found in Kampung Baru, whose people are all Minangese. The women
were not only transporting materials or other supporting activities but also digging, lifting thepipe and other jobs usually done by men (Figure 2). This is caused by Minang’s culture where
the people used to work together, known as Gotong royong. Moreover, women are used to do
agricultural works, which help them much easier to do physical works during project
construction. The flexibility of women social mobility in the context of culture have reduced,
which create opportunity and chance for poor women to work out side their home to support
family life. The same situation is also found by Joshi, D and B. Fawcett (2001) in donor
funded and managed urban slum projects.

In the study area, men and women do not paid for their unskilled-labor, except for skilledlabor that usually only one or two people from the village. During the construction works,
women are used to do the unskilled works, such as lifting or transporting materials. Women
do not get any new skills or knowledge related to technical aspect. If the problems occur after
the project completion, the only thing women can do is asking men’s help or waiting for the
Village Water Committee (VWC) to fix the problem. Women should be involved in the
training on technical aspects, so that they can get new skills and able to solve technicalproblems.
People participation in operation and maintenance
Based on the WSLIC II approach, people were fully involved in the operation andmaintenance of the facilities. When the construction is completed, the operation andmaintenance of the facilities were delegated to the community. For this purpose, watercommittee was formed at the village level. In Kampung Baru, almost all of the people
including men, women and children use RWSS facilities. However, the frequency in using
water facilities is quiet different; men usually use the facilities for drinking but rarely use thefacilities for washing their agricultural products.

Table 2 shows the frequency of people involvement in the operation and maintenance offacilities. Women use the facilities more often than men do. The reason why people rarely use
water facilities is because they have water source near their house. They feel more
comfortable to use water from river than other water sources. Water facilities are only used as
drinking water. The frequency in using water facilities influences the task of maintenance.

Women have more chance to do maintenance task, which is mainly to keep the area aroundthe tap clean. The maintenance task particularly related to the damage of facilities consideredas the responsibility of VWC. People report any damage or destruction to the VWC (Table 3).

Observing women activity in fetching water, it was found that they spend more time to fetch
water because they cannot bath in the taps. Some of them are reluctant to wash their clothes at
the tap stands because the location of tap stands along the roadside. Consequently, they haveto collect more water to their home. People collect water from springs or well two or threetimes a day before water facilities were built. When the facilities have been built, the waterneeds increased, but the frequency of fetching water is not significantly different from before.
This is because children can bath and collect water for their own needs.
People participation in monitoring and evaluation
Monitoring and evaluation activities are done to assess the functionality and sustainability ofthe scheme. However, community participation in the evaluation and monitoring phase is still
low. This might be caused by low level of community educational background and lack ofknowledge on water scheme, especially on technical aspect. The people are not able to detect
facilities destruction. They cannot give any suggestion for a better condition of the RWSS
facilities. Monitoring and evaluation conducted by donors are focused on the community
satisfaction on water supply and sanitation facilities. However, the results show that most of
the people never asked about any problems during the operation of water facilities (Table 4).

People participation in monitoring and evaluation is influenced by the participation in threeprevious project’s cycles: initiation and decision-making, implementation, operation andmaintenance phases. The knowledge about the system can be derived from their participationin previous phases. The people will be benefited by the system and will feel that the systembelongs to them if they were involved in every project phase.

People participation and project sustainability
Monitoring and evaluation of the project was held by the independent agency two years after
the project accomplished. Although it is not a proper way to represent the sustainability of the
project, which collected the information only at single point in time, at least it can describe
the condition of water supply and sanitation facilities in the study area. Focus group
discussion was applied during the monitoring process. Field visit to villager houses was also
conducted to get the information related to consumer satisfaction on the scheme.
The physical condition assessment in terms of materials used during the construction showsthat the facilities construction such as water catchments is in good condition. It is also
protected hence water contamination can be avoided. On the other hand, the tap facilities areoften damage or broken. People were not aware to repair the broken tap. The leakage of thepipe and joint seems to be a problem that should be considered although it is not yet influence
the quantity of water supply to the taps.
The sustainability of water supply and sanitation project in the study area is threatened by thelack of people’s awareness and general knowledge on the schemes. This is due to community
participation in project phases; women were not effectively involved as well as men. Lack ofownership and responsibility on the facilities lead to the damage of the facilities. Some of thetaps are no longer used by the community because they are located near the houses that haveaccess to water source. Women have to fetch water not only for drinking but also for bathing.
Women cannot bath freely in the taps because the taps are located along the roadside. Most of
the people do not use public latrine facilities anymore. They feel more comfortable to defecate
in the streams or in the river. It is estimated that 3% of the poor, 14% of the middle and 9% of
the rich family who has built sanitation facilities.

Abstract
The paper presents an approach called WAND or water, agroforestry, nutrition anddevelopment which provides a multi-pronged approach towards water quality conservationand poverty alleviation in Mindanao. Our contention is that water quality conservation is
directly linked with poverty alleviation. From an initial area of 2 barrios in 2003 the initiative
has grown to cover 26 barrios in 3 provinces. The latest inclusion is ecological sanitation thatcloses the loop between agricultural production and food consumption, prevent contaminationof water sources and prevent the spread of diseases. The wand approach is effective andreplicable in most rural areas in the Philippines because a) it provides a menu of solutions tovarious farmers’ felt needs and problems rather than proposing single solutions, stakeholder
mobilization and linkages is strong and we collaborate and cooperate rather than trying towork alone; b) self-propelling local organizations are established to sustain the process.
These grassroots organizations are federated in order to provide a single platform for policy
and advocacy works; c) agro-reforestation is advanced as a viable way to improve water
sources at the same time providing precious food, fodder, incomes and various resources tofarmers. This is deemed important in view of the burgeoning population and lack of land
resources.
Keywords: ecological sanitation, sustainable farming, multi-pronged approach
Introduction
The WAND Foundation (formerly LEF, Inc) started as a localized initiative implemented in2003 in 2 barrios in Mindanao aptly enough with water, agroforestry, nutrition anddevelopment (wand) components. In 2004 we won in the World Bank-initiated Philippine
Development Marketplace competition and since then, several donors have funded its
expansion to cover 26 barrios in 3 provinces in Mindanao in about 4 years time. One inclusion
in 2007 is the integration of human excreta management by implementing ecosan and using
human waste as fertilizer thereby closing the loop between food production and consumption
and lessening disease incidence and groundwater contamination. This won us another award
in the recent Philippine Development Marketplace sponsored by the World Bank in April
2008.
The context of our effort is Mindanao, in southern Philippines which is a region sufferingfrom poor infrastructure, high poverty incidence, and violence that have claimed the lives ofmore than 120,000 in the last three decades. The violence and rebellion are derived fromunfulfilled hopes of peace and economic prosperity after the 1986 restoration of democracy.
In the project areas before the project started socio-economic exclusion and poverty isprevalent, availability of potable water difficult, most of watershed areas remain denuded, illhealth and general malice characterizes the population. The government is unable to deliver-68-the much needed services especially in the agricultural sector where it is most needed becauseof the gargantuan budget deficit, insurmountable foreign debt servicing, corruption andoverburdened bureaucracy. The rural areas remain stagnant with very few viable enterprises
operating and farmers producing primary crops being subjected to pricing dictated bymiddlemen. This project is slowly reversing the difficult scenario by the implementation of
potable water system, developing sustainable small farms by integrating vegetable gardening,small and large animals and planting fruit and timber trees, forming functional rural
associations and improving the position of women in the community. Our overall objective is,“to uplift the socioeconomic situation of resource poor marginal farming families so that they
will be able to live more humane and dignified lives and fully participate in the life of thecommunity”.
Discussion of project components and methodologies
The project is implementing a multi-pronged approach consisting of the following:a. Installation of community-managed gravity-fed water system. The water system is series ofcatchments emanating from the source and connected to the population center by sanitarypolyethylene pipes. The water systems are managed by the barrio association.
b. Community education through barefoot extension agents. The agents are trained volunteers
from among the members of the community and act as resource person in their community.
c. Community-based nursery and communal tree planting of watersheds and eroded hillsides.
The local associations are mobilized to plant and care for their planted area. Most important
ASEAN fruit and tree species are raised and planted to enrich and maintain local biodiversity.
d. Promotion of vegetable gardening to combat malnutrition and improve incomes.
e. Large and small animals are released to farmers to improve their farming system and lessen
the burden in the field. The small animal is also a ready source of protein and income.
f. Organizing associations to sustain and manage the initiative. Organizing local associations
follow a 3-stage iterative process of formation, strengthening and organizational consolidation.
g. Incorporating gender and development in the whole process and nurturing women leaders.
Our outputs so far include the following:
1. Installation of 5 gravity-fed potable water systems in 5 barrios in Misamis Oriental.
2. Establishment of 39 unit ecological sanitation toilets to control contamination ofgroundwater and waterways and using the processed human excreta as fertilizer for theseedling nurseries.
3. Establishment of 3 central nurseries to produce high-quality seedlings and planting
materials. The nurseries are able to produce an average of 20,000 seedlings per year and theplanting of 75,000 fruit and timber trees in 200 hectares watershed areas using ASEAN’s
most important species (Durio zibethenus, Mangifera indica, Lansium domesticum, etc).
-69-

5. Promoting agro-reforestation and vegetable gardening among a total of 2,500 beneficiaries.
The agro-reforestation integrates cash crops, trees and farm animals in a given area of land.
6. Training and deployment of 175 progressive local farmers as barefoot technicians andextension agents able to train other farmers and share on the material inputs.
7. Organizing and strengthening of 23 local associations and neighborhood groupings able tomanage their own activities and sustain the process through participatory planning andimplementation and organizing and building the capacity of a farmers’ federation.
The success factors of the project include the following:
1. Rather than providing ready made solutions to peoples’ felt-needs, the project provided amenu of inputs involving water, farming development, nutrition and health for them to selectdepending on their needs, capabilities, personal choice, budget and the condition of theirfarms. I posit that efforts at water quality conservation will not be successful if the approach
is singular and not integrated and divorced from the needs of local, resource-poor farmers.
One example of this is the massive drive of a government agency for people to plant trees in
the watershed areas to help ensure that water sources is protected. The problem is that people
do not participate because their need is more on food and cash crop and they do not see any
value to planting timber trees such as Gmelina arborea.
2. The participation and collaboration of stakeholders involving local governments, line
agencies, business, youth and religious ensure that support is generated at various levels. Our
experience shows that there is a need for each of the stakeholder to know fully well their roles
and responsibilities before they will participate fully.
3. Eco-sanitation provides ready and cheap fertilizer for farmers at the same time containing
the spread of diseases carried by wayward excreta. It also weaned farmers from thedependence on chemical fertilizer and generates much needed savings. However one problem
that we are encountering in the promotion of eco-sanitation is local people’s natural
abhorrence to human excreta.
4. The promotion of ASEAN’s most important species such as durian, lanzones and rambutan
help ensure that this specie will not be lost forever and instead will help improve biodiversity
as well as improve incomes of farmers. In our experience in the field, we found out that theyplant trees only if they find that this will provide them with clear source of income in the
future.
5. The creation of community farmers’ groupings and a federation help ensure localizationand sustainability of the practices and integrate it into the cultural fabric of the community.
The current practice by local extension agents is to train individual farmers (early adopters)
hoping for a multiplier effect. In the case of our project, we focus more on building thecapacity of local groups and start intervention from these groups then expand to nearby
villages as the groups become more able to manage their own affairs.

-70-Cross-cutting Themesa. Gender and Social Inclusion
The subject and object of the project are the near-landless and small farmers in the area. The
theme is ‘development with equity.’ The rule of thumb in community organizing is that atleast 50% of the leaders in the barrio associations are women.
b. Leadership and Community Empowerment
In 2007 we started in-depth organizational development activities and consolidation of thelocal associations organized in the area. Toward this end, some of the farmer-leaders felt that
it is high time to create an umbrella federation that will govern all the rest of theclusters/association created for ease in communication and management. Thus for this year
the “Nakasama Na” or Nagkahiusang Kapunongan sa mga Mag-uuma nga Nagtikad sa West
Misamis Oriental (Federation of Small Farmer Tillers in West Misamis Oriental)was born.
The federation is composed of 23 clusters/neighborhood associations.
c. Promotion of biodiversity and watershed amelioration to improve the integrity of water
sources
Our agroforestry focus is in promoting ASEAN’s most important trees such as rambutan(Nephelium lappaceum), mangosteen (Garcinia mangostana), lanzones (Lansium
domesticum), santol (Sandoricum koetjape), tamarind (Tamarindus indica), mango(Mangifera indica) and noni (Morinda citrifolia) for their high valued food and medicinal
source. Promotion involve production and dissemination of a popular community-based
nursery and tree planting manual, tree planting and small-scale wood processing to generate
economic value and market out of planted fast-growing trees. The problem we try to solve isin the fact that seedlings are not readily available and farmers have to source seedlings fromfar places and not so well known quality and origin. Also seed collection for seedling
production does not discriminate what type of trees to use and therefore quality suffers much.
The practices that we promote include; a) use of high-quality seeds and planting materials intree planting resulting to high quality and production of trees with good genetic quality, b)
improvement of knowledge in the control of pest and diseases in the nursery resulting to goodquality seedlings, c) proper management of the nurseries (regulated lighting, supply of water,etc)., d) proper field planting techniques (spacing, holing, fertilizing, pest and disease control,etc), e) improved knowledge in wood processing resulting to low wastage and high economic
value of processed wood, f) increased appreciation of the economics of tree planting and the
management of fruit and timber. The following topical areas were covered in the education
activities; assisted natural regeneration; timber stand improvement, small-scale plantation
management, sloping land techniques, biodiversity management. Small scale woodprocessing is covered because there is a dearth in knowledge on the proper use of woodespecially coming from small-scale plantation resulting to economic losses and wastage ofscarce resource.
Currently we are establishing a “living museum” wherein forest and upland resource of
mostly Higaonon and Subanen Indigenous People will serve as the main resource andindexing, propagating and marketing seedlings of ASEAN’s most important trees in
Mindanao. The concept of the living museum is different from the traditional herbarium,
enclosed type but will feature not only the forest resource but also their living culture and wayof life. A 6-hectare land area is being used for this initiative. We are starting to look at how-71-we are able to produce and market products from plants for the local market and later on toseek commercial partners from outside. For example banaba (Lagerstroemia speciosa) grows
wild in the area and is said to be high in corosolic acid which is a natural plant insulin anduseful in lowering blood sugar. Cough remedies coming from plants are already marketed
locally with some success. Treatment of intestinal parasites of farm animals using leaves of
local plants are also being done.

b. Production of compost/organic matter annually estimated at 35 kilograms per ecosan user
x 3,360 users = 117,600 kilograms. This compost when used to plants will increase the plants
tolerance to water stress and is essential for nutrient utilization.
c. Less spread of diseases as a result of open defecation.
I don’t have empirical data yet for letters a and b and this will be subject to further research.
Small water system establishment
The water system in Barrio Gimaylan is impounded using deep well pump and it isoperational already since 2006. The system is being managed by a water committee with LEF
as the advisor. During this period, the water system broke down 2 times but was immediately
repaired and running again with the repairs shouldered out of the monthly user fees collected.
-72-

The system is indeed a big boost to the 120 inhabitants in the area who are dependent upon
the Gimaylan Creek for their water needs. With the water system, incidence of diarrhea
especially among children was drastically reduced because using the water in the Gimaylan
creek is shared with the many animals, people and waste upstream. People also do not need
any longer to negotiate steep slopes in order to get water from the creek and carry it upwards
to their houses.
Three other water systems were established in 2007, one in Dipolog City and another in barrio
Pagawan, municipality of Manticao, Misamis Oriental and in Balintad, Manticao, Misamis
Oriental. The water system in Dipolog consists of a concrete catch basin and a deep well.
Water is impounded using a portable pump. The water system serves 15 families in the area
as well as it is the main source of water for the seedling nursery. The water system in
Pagawan is gravity-type with water drawn from a natural aquifer. The main source isconnected by polyethylene piping and it is serving a total of 200 families. Incidence of
diarrhea has been drastically reduced because the local inhabitants no longer get water fromrain pools and mud holes. The water system in Balintad is also gravity-type and serves 75
households. A spring source is where the water is taken and stored in a reservoir.
Draft Animal Loan
The draft animal continues to provide the centerpiece asset that the farmer can have. Ourdraft animal dispersal system tried and tested for over 4 years now from animal procurement,
release, care and management and repayment collection/passing-on is one of the mostsuccessful program in the country today with most draft animal dispersal program especiallythat of the government ending-up as failures, with the ingredient of community organizing
and empowerment lacking in substance. Aside from the organized communities we continue
to provide technical assistance to ensure that the animals are well taken-care of and that passon is ensured.
A total of 202 draft animals have been released to 200 beneficiaries adding to the 44 released
in 2006-2007 with a total 246 animals in all. Fifteen offspring has been realized already but
there were 3 mortalities recorded

Challenges of the Project
The challenges of the project include the following;a. Lack of government support and weak barrio government units. Municipal and barangay
governments have very little resources to support development interventions in the rural
areas. Added to this is the problem with weak planning and corruption.
b. Peace and order problem especially in the interior areas and massive evacuation results toloss of lives and livelihood.
c. People’s slow acceptance of human excreta as organic fertilizer especially for homegardens.
d. Very poor soil condition takes so long to nurse back meanwhile people have to use it togrow food. This problem is coupled with the burgeoning population, loss of biodiversity
and soil erosion.
Conclusion
Our approach towards water quality conservation, i.e. watershed rehabilitation, protection of
upland water sources and ecological sanitation to prevent groundwater contamination maybe
different from other approaches and thus highly successful in the sense that;a) We do not provide single solutions rather we provide a menu within the ambit of water,
agro-reforestation (crop-tree-animal integration), nutrition and building self-propellingorganizations of which local farmers can chose from. This is far more superior with therealization that felt needs of farmers are varied and that they participate only when they feltthat there is something in it for them.
b) We promote ASEAN’s most important trees in the protection of the watersheds and water
sources and this approach creates a lot of interest among local and international supporters asthese trees are neglected but have the potential to improve incomes at the same time
improving our watersheds.
c) We work closely with a multitude of stakeholders and not limit only to a few. We realizethat more hands and heads are indeed better. Importantly, we work in close coordination withlocal government units in the areas fully realizing that they have much to share in terms ofpolicy and technical support. Other players in the NGO community sometimes bypass LGU
collaboration in order to remain “pure.”

Abstract
Ayasegawa River was the most polluted river in Japan. Fig.1 shows “the ranking of the polluted
river in Japan” which is disclosed by Japan Government every year. It shows that Ayasegawa
River records 19 times continuously, total 25 times the worst from 1972. How ashamed result is
it! Government and the local gave up the improvement, and they recognized the status. But werealized that they did the best for the improvement of the river very hard when we started theresearch in our campaign. For example, government and prefecture have planed distributionplans 10 years ago and have constructed the direct purification plant. NPOs have also done thegrassroots actions individually to change the river to a clean and clear one. We, Water forum
which connects Tokyo Bay to Arakawa, Tonegawa and Tamagawa River, had no information
about Ayasegawa River at that time. We knew the river recorded the worst polluted river inJapan, but we believed the responsibility in the government and the local. Saitama prefecture
raised the big campaign, “Breaking the most polluted river in Japan: Ayasegawa River” in 2005.
Our NPO also agreed to the campaign. We campaigned with the basin NPO together widely.
This report is the review of the big campaign.

area in Japan.

LocationFig.2 shows the Tokyo metropolitan area in Japan. Tokyo Bay is located on the south, andTonegawa River and Arakawa River are located on the east, on the west, respectively.
Ayasegawa River is located in the middle. The river originates independently. The upper side of
the river is used as agricultural irrigation canal. The middle and downstream are used as
agricultural and storm drainage systems. The river is main role to accept the domestic-75-

wastewater in the resent years. It accepts the domestic wastewater and drainage, and reaches theTokyo bay through Arakawa River. The area of the river basin is 178 km2, the population of thebasin is 1.25 million, and the length is about 47 km.
Features
The flood control project of rivers began 400 years ago in modern Japan. Ayasegawa River had
abundant water supply, and was the booming shipping and fishing industries before because it
connected Tonegawa and Arakawa rivers. Rice farming was the most important in the modern
Japan's agriculture, so people ensured that water was the highest priority. Ayasegawa River wasused for the agricultural irrigation and drainage systems. The river was loved and developed bybasin. However, with an increase in the population of capital Tokyo, has also increased the
population around Ayasegawa River. Fig.3 shows the change of the population. The rapid
increase in population has changed the condition of Ayasegawa River. Naturally, the river hasreceived wastewater from houses and factories. The receipt of the wastewater has brought theriver to the most polluted river.
Cause of the most polluted river in Japan
Whenever people live, people must be therelease of wastewater from houses and factories.
River pollution is inevitable. In the case of
Ayasegawa River, is it the same reason? As
described in Fig.4, the wastewater from houses,from industries, and agricultures are almost 73%,
18%, and 5%, respectively. About three quartersof wastewater come from houses. Classified thewastewater from houses in detail, we can findthat it consists 40% from kitchens, 30% of toilets,
20% from bathrooms, and 10% from close
washers.

you permit that the polluted water is drained without
any treatment? No one can clean up. As you recognize, you have to use the water after sometreatment. Water is circulating around the world, and into the space. Our campaign, "Campaign
breaking the most polluted river in Japan", means a domestic wastewater measures andimprovement of manner for draining the domestic wastewater. In other word, it is consciousness
by the residents. This is our mission and duty.

Activities of our campaign
The following is our various activities breaking the most polluted river in Japan.
Activities by government and prefecture1) Removal of the polluted sediments
Large amount of polluted sediments deposits in river. The rivers which have ability of self
control system, for example, with large amount of Dissolved Oxygen (DO) can decompose thesediments, but in the rivers in urban areas the sediments deposit. The deposited sediments must
be removed by a mechanical way like mobile cranes.
2) Purification plant
Water from the river is sent to the plant directly, and returned after purification. 2 plants by theGovernment and 8 plants by the prefecture exist through the Ayasegawa River.
3) Securing water
Main industry in this area is farming, so the required water volume of the river theoreticallyreduces to 0 in winter. To compensate it, some amount of water is supplied. Now thegovernment decides 1.8m3/s of water supply to Ayasegawa River. The prefecture decides
0.5m3/s of water supply. In the near future, the amount will be increased.
Drainage measures and treatment of effluents
Drainage measures in Japan are introduced here. As I mentioned before, 73% of the reason was
the domestic wastewater. The following is the drainage measures in Japan. It consists of 75% of
public swage treatment, 10% of Johkaso treatment which is on site treatment, and 15% of
non-treatment. According to the government instruction, the public swage treatment is done by
the prefectures. Large scale of treatment plants is constructed in urban areas, the drainage pipes
are connected with the public pipes, and the wastewater is collected. Most treatment plants are
adopted activated sludge process. Johkaso treatment is mainly used in the suburbs, and every
house has a small plants. Ability of treatment is improved to 6~10 mg/L of BOD. Additional andadvanced investment for the treatment causes the availability of use for factory and farming.
Activities of NPO
Basic part of the campaign was done by NPO. And main purpose was improvement of mannerfor draining the domestic wastewater and of consciousness by the residents. The following issome examples of our activities.
1) Clean up campaign
We call it "Gomihiroi" in Japanese. It is held all over Japan. Some groups are doing their action
every day, every week, every month and once a year. Wastes must be divided into 4 types inJapan. The waste is divided by the type to be re-used and recycled. The divided wastes which
the NPO gathered are packed and sent each other by the government. Children can attend thiscampaign with observation of nature. They can observe changes of the plants and the bird
watching. They also can analyze the quality of water through the campaign. We sometimes
prepare a short game in it.
2) Research of water quality in the river
It is very important to analyze the water quality of the river and assess the environment.
Scientific data is acceptable for any people. It is also important to compare with the past such as
1 year, 5 years and 10 years ago. Each NPO can adopt the research methods and items like COD,
NH4, PO4, NO2 and NO3. But it is difficult to analyze BOD, so we ask for analyzing it to theprofessional organization if necessary. We also can analyze transparency, flow rate of the stream,temperature, smell and color of the water. Our analysis technique is not so specialized, but it is-77-

very meaningful to measure as a perspective of the residents frequently. Finally we discuss themeasures with the government together using the collected data.
3) Education about the environment
The education system is studied in primary schools and junior high schools. Japanese schools
have some curriculum of social issues, and students of each grade study various levels of thesocial issues. NPO can support the lessons regarding the environment, river and water. The
students can study by the documents and pictures of our activities in their classroom. They
sometimes can experience analysis of water quality. They discuss the reason for pollution of theriver each other and the better way to recover the river.
They sometimes have open-air lessons. The lessons take more 2 hours. We take the students to
the river, and they smell, observe the color of water, clean around the river and watch many
plants, fish and birds. They realize the dirty and polluted river by themselves.
The students usually talk to their family at home about the lessons they learned. Their familytalks to their neighbors and friends. The information is spread automatically. We are looking
forward to seeing the reports or essays written by the students.
Activity using check sheet
We also start an action using a check sheet not to pollute the river. The residents check theirlifestyles by 10 items. The items are the following.
1. Use any filters at the drainage area of kitchens and baths.
2. Not to cook the excess amount of meals, and not to throw leftovers into the drain of kitchen.
3. Manage to consume all the vegetable oil for fryer, and adsorb on the papers or waste cloths.
4. Wash the dishes with oily food using acrylic wash sponge.
5. Use the washing water of rice to feed for plants and the others.
6. Wash cloths as much as you can, and use adequate amount of detergents.
7. Use the soap which is good for the environment in laundry, car wash and so on.
8. Drain to the public treatment system, or maintain and clean up the Johkaso regularly.
9. Clean up the river and drain paths and attend the clean up campaign voluntary.
10. Attend the seminars regarding any environment issues.
It may be difficult to agree with some items for people outside Japan. But these are very useful
items and familiar in Japan. Few people can do the right actions against all items from the
beginning, but it is a useful action to realize by them. This action has not been done by only
NPO. Cooperation with city administration is necessary. The action needs huge effort because
we ask for any assistance of many city organizations. Action once is not effective very well, so it
should be repeated 3 times and 5 times. People experienced the check sheet 3 times can successmore than 80 %. Therefore continuous action is the most important.
Nonuse of detergent
An Acryl wash sponge is enough to wash dishes without detergent. We distributed the washsponges to the basin residents. It is a handmaid sponge by NPO members. The detergent is oneof the main reasons for deterioration of water quality. Do not use it as possible. Use of the acryl
wash sponge is effective.
Recommendation of tidy (garbage in the kitchen sink)
It is important not to throw out the solid waste from kitchen as possible. We also distributed atidy. The solid waste can be removed from the domestic wastewater by the tidy. These
continuous and steady actions were base of our campaign.
-78-Collaboration with the government
NPO's actions are only inside the community even if we do the best. On the other hand, thegovernment's action also has various limitations. The most important thing is that NPO and thegovernment realize by themselves what we can do or not, and collaborate together. The residents
trust and cooperate with the collaboration after ripening relations. But it is difficult to have agood relation from the beginning. This is the result of continuous efforts.
Effect of our campaign
Collaboration among NPOs, the government and the private companies
Each NPO has been campaigned separately for a long time. They had a limitation of their action
area and action issues. We also have known that Ayasegawa River was the most polluted river inJapan, but NPOs did not any collaboration and cooperation. Saitama prefecture asked for thepolicy of the campaign to NPOs in 2006. Only 5 NPOs attend the campaign at first. After thateach NPO cooperated together, asked for other NPOs to join. Now more than 40 parties attend.
Clean up campaign is sometimes done by one NPO, and sometimes by many NPOs. Non NGO
members such as the government and residents become to attend frequently. This change means
the progress of our campaign. Our NPO is also encouraged.
The system of governmental administration is not so simple. Ayasegawa River is not so long
river (64 km), and the downstream 10 km is administrated by capital Tokyo, the upstream 40 km
is administrated by Saitama Prefecture, and the middle 15 km is administrated by the national
government. It has 60 branch rivers. Each river is administrated by 13 cities. No controlled
systems between these organizations existed, so the actions are decided individually, and thegovernment noticed that this situation was worse, but less effort for improvement was tried.
Recently the improvement among the governments is progressing, and collaboration with theresidents is also tried.
Collaboration with the private companies is also progressing. They release large amount ofeffluent and some chemical compounds. In 2007, 40 companies support economically. The basincompanies also hope to have a good relationship with the basin residents, and to make the riverclean. They cooperate with NPOs and educate in their office. We, NPO, visit the companies, tellthem to thank and report our campaign. This causes a good relation and collaboration.
Clean up campaign is one of the most familiar activities for the NPO. The action is introduced
above. This action did not go well without collaboration with the government and NPO, but
most case goes well. The volume of the waste is gradually decreasing. The people who throw
away the waste is decreasing, because the active NPO becomes to increase. Clean up campaign
is quite simple. Clean up campaign means that picking up the waste thrown by others, so people
feel bad. But the mind of picking up the waste, not throwing away the waste and willing to clear
a river is the same as the mind of loving the water. And this is the origin of heartwarming
communication.
Campaign of cooperation with school becomes more active. The campaign is held from 50 to
100 times a year around Ayasegawa River. Many NPOs support each other depending on theissues and themes.
Collaboration among NPO, the government and the private companies is really progressing. The
residents do not believe and cooperate without the collaboration. We convinced that the
campaign becomes powerful, and becomes to have fruitful results, because the collaboration isgoing well, and the residents believe and feel how the collaboration runs.

Conclusion
We were surprised that Ayasegawa River got status of the most polluted river in Japan. It lasted
for 15 years and 19 times. We appreciate and thank that the government made a decision ofstarting "Campaign breaking the most polluted river in Japan". The greatest finding in the
campaign is that the drainage treatment of domestic wastewater occupied 79 % in thewastewater would be the most effective. Besides, we decided that main activity in the campaign
should be an improvement for manner of domestic wastewater. We convinced that the decision
is right.
The residents attending the campaign really recognized useful. As a result, Ayasegawa Riverjumped up from the worst position and got an honor of the largest improvement river in Japan(against 10 years ago, 20 years ago).
Progress in collaboration among the government, the prefecture, cities and NPOs will be a great
driving force around the issue.
Saitama prefecture decides that they really try to improve a maintenance level of Johkaso. It is awonderful decision. The decision leads the residents to cooperate.
We had a confidence our activity because our responsible campaign gave a great result. Finally,tightening network of the residents and formation of the manner are also another effect.
What we have been pursuing for 15 years is that Ayasegawa River becomes the cleanest andclearest river in Japan. The aim has been fulfilling as expected.

Abstract
The future quality of water is one of the most pressing environmental problems in most Asiandeveloping countries, like Philippines. With urbanization, water governance has to cope withincreasing demands for steady supply and access to potable water, both for the immediate andlong term. National institutions usually manage water supply/quality and sanitation. However,
local governments still lack the ability to ensure efficient and sustained delivery of basic
water services. Thus, some institutional development interventions among local governments
were initiated to monitor, improve and sustain water quality and conservation for domestic,
industrial, agricultural and other uses. Strengthening the local government's mechanism isimportant for integrating efforts, coordinating and managing integrated water resources andrelated water operations in the area and driving the different sectors involved to treat water
resource in an integrated manner. Such initiatives hopes to shift from fragmented to integrated
local water agenda and action, to be catalyzed by an integrated management scheme at the
local government level. Specific targets for capacity-building are the strategic planning anddevelopment of the local government and the public utilities sector that manages the water
treatment facility. This paper presents case studies on water quality management programs
and intervention reforms for sustainability.

Introduction
In response to the growing problem in water quality, the Philippine government enacted the
Clean Water Act (CWA) in 2004 and its Implementing Rules and Regulations (IRR) the year
after. Praised for its innovations in water quality management, the Act and its IRR require
integrated approach, stronger collaboration among stakeholders, and promotion of coownership of the water bodies. From 2001 to present, the Department of Environment andNatural Resources-Environmental Management Bureau (DENR-EMB) through its regional
offices have monitored 238 water bodies either for classification or for regular water quality
monitoring. Depending on the regions’ resources, monitoring for these water bodies is done
monthly or quarterly. In ADB’s publication "Asian Water Development Outlook 2007” or
AWDO 2007, the ADB warned that water availability in the Philippines could be"unsatisfactory" in eight of its 19 major river basins and in most major cities before 2025
(ADB, 2007). The ability of groundwater to meet future water demand has been projected tobe limited, amounting to only 20 percent of the total water requirement in the country's nine
main urban centers by 2025. This development review study is focused on qualitative data,
through interviews and observations, and quantitative data, where cause and effect is sought-81-

to produce generalizations on policy issues and challenges. Some case studies on local
governance initiatives on water quality management program (WQMP) and intervention
reforms, as well as best practices and lessons learned on WQMP are presented and discussed
in the succeeding sections.
Water Quality Management Programs (WQMP)
Philippine water quality is assessed based on the set beneficial use as defined in the DENR
Administrative Order (DAO) 34, Series of 1990. Under this DAO, there are 33 parametersthat define the desired water quality per water body classification. Accordingly, a water bodymust meet all the criteria of each applicable parameter 100 percent of the time to maintain its
designated classification. In the absence of a water quality index, an interim methodology
based on compliance to DAO 90-34 water quality criteria is used for all surface waters.
Parameters monitored include: (a) dissolved oxygen (DO), biochemical oxygen demand(BOD), total suspended solids (TSS), total dissolved solids (TDS), and heavy metals forinland surface waters; (b) fecal coliform, nitrates, and salinity (chloride content) for
groundwater as defined in the Philippine National Standards for Drinking Water; (c) DO,
coliform, and heavy metals for coastal and marine waters; and (d) biological parameters suchas phytoplankton, zooplankton, and benthos were monitored in selected water bodies. On
legal and policy aspects on water quality management, the Philippines has an extensive water
and water-related legislation and regulations that provide the legal bases for programs onwater quality management. From 2001 to 2005, one major legislation on water quality
management was passed. This was RA 9275, otherwise known as the Philippine Clean Water
Act (CWA) and signed into law on March 22, 2004. Water quality management in thePhilippines is spearheaded by the EMB of DENR. In support to the DENR’s mandate, othergovernment agencies, financing institutions, and donor agencies have also implemented
programs and activities on water quality management. The Philippines is a recipient ofofficial development assistance for water quality management. Its main donors are: thegovernment of Japan through the JICA and JBIC, ADB, USAID, United Nations system, and
the WB. Grants have been provided by bilateral agencies as environmental assistance, whileloans to finance investments in environment projects have been provided by ADB, JBIC, and
WB.
Best Practices and Lessons Learned in WQMP
This section presents best practices and lessons learned in water quality management,
including waste minimization efforts that could be adopted by others. This process will not
only give credit to those “good performers”, but will also allow others to duplicate thedocumented “best practice in water quality management.” In addition, this section showcases
efforts of government agencies, private sectors, business or industry associations, LGUs, civilsociety, communities, academes and others (Fruh,2003).
River Water Quality Management - Initiated as part of the USAID project on Sustainable
Agriculture and Natural Resources Management, the Philippine Water Watch (PWW)
capacitated local farmers in understanding and performing water quality monitoring that was
focused on drinking water quality and its impact to public health (World Bank, 2003).
Moreover, local farmers developed the capacity to address problems on bacterial
contamination, soil erosion, and sedimentation. A successful technology transfer wasdemonstrated through exchanges in technology adoption. For instance, after the PWWvolunteers used the Easygel rapid method for E. coli testing, it was adopted by the AWW. In-82-

the same manner, methods for TSS and stream discharge sampling that were initially used in
the Philippines. The PWW program resulted to the formation of three active groups in
Mindanao and Bohol. Together, they have collected thousands of stream water samples. This
multi-year information documents a clear gradient of declining water quality across four subwatersheds of the Manupali River, which is related to human population, deforestation, andagricultural development. Drinking water supplies have been identified as contaminated, andpublic health risks have been minimized through remediation. PWW volunteers have been
active in educating their neighbors in water issues by giving presentations at village meetingsand in schools. The pioneering effort of the PWW has attracted local and national attention,with great potential to impact water policy. The data and the process of community-based
water quality monitoring have been incorporated into the Natural Resource Management Planof the Municipality of Lantapan, Bukidnon. The local government of the Province ofSarangani initiated a similar water quality monitoring program in their region. Moreover, thePWW data were used by the Philippine Institute for Development Studies to advise Congresson the value of community-based water monitoring during the formulation of the CWA.
Lake Water Quality Management - Laguna Lake is one of Southeast Asia’s largest inland
water bodies. Since its establishment in 1966 through RA 4850, the LLDA has beenprotecting and preserving the quality of the Lake as well as the 21 river systems that flow into
it. The holistic and integrated approach that LLDA is implementing not only reduces pollution
draining into the lake and improves lake water quality but also becomes the benchmark inwater quality management. Some of the best practices that LLDA carries out include: (a)Controlling point source of pollution through the EUFS – A market-based instrument thatencourages companies to invest in and operate pollution prevention/abatement systems within
their establishment. Applying the “Polluter Pay Principle”, the system provides direct
accountability for damage inflicted to the Lake. Since the implementation of EUFS in 1997,
the LLDA observed decreasing annual BOD loadings from 5,402 MT in 1997 to 193 MT in2004 (Figure 21) generated by 222 firms; (b) Cleaning up river system by creating additional
livelihood – Tagged as ‘Environmental Army”, this group convenes monthly to haul out
wastes from various rivers in the Lake’s basin. Once biodegradable river wastes are collected,
these are fed into drum kilns, until they are carbonized and later pulverized. The carbon
particles are then mixed with a binder and pressed into their final shape and form. After which,these are dried, packed, and sold for PhP15/pack of 25 pieces. The briquette-shaped charcoal
is more solid and slower to burn than the flake-shaped charcoal being sold commercially. It
provides livelihood to poor fisherfolk and creates opportunities for small business enterprises
around the Laguna Lake Region, in the provinces of Rizal and Laguna, and in Metro Manila.
Though the project offers a host of environmental benefits and provides livelihood
opportunities for the marginalized sectors, marketability of the briquettes has become astumbling block for the project’s sustainability. Local acceptability and finding potential
investors are some of the issues that have to be solved. However, despite the set-back in themarketability of the converted wastes, the environmental army initiative on river clean-up has
created an advocacy among the communities to take active roles in river/lake rehabilitation.
Public-Private Sectors’ Collaboration to Promote CP – Promotion and adoption of CP is one
key strategy that is strengthened under the CWA to prevent point sources of pollution. Interagency collaboration has demonstrated success in transforming the paradigm of industries tofocus on an integrated, preventive environmental strategy to processes, products, and services
to increase efficiency and reduce risks to humans and the environment. A successful
collaboration was illustrated by the Metro Cebu Environmental Initiatives Council (MCEIC)-83-

and its partner agencies and industries in Region 7. To give due recognition, a MOA wassigned in April 2004 by the MCEIC, Pollution Control Association of the Philippine, Inc.
Region 7, Cebu Chamber of Commerce and Industry, Inc., and the DENR-Region 7.
Signatories of the MOA agreed that companies that document and submit their CP practices
be given due recognition. A total of 21 firms submitted their CP program documentation andwere then reduced to 10, following this set of criteria: (a) Innovativeness of CP Technique
Used; (b) Pollution/Waste Reduction Attained; (c) Cost Savings Result; (d) Increase in
Production Efficiency; (e) Proper Resource Use/Management. These firms were given“Award for Outstanding Cleaner Production Practices” in June 2005. As an added incentive,
Region 7 granted the awardees environmental permits with five-year continuous validity.
Pilot and Demonstration of Water Actions (PDA) - This PDA strengthened the Baguio City
government's mechanisms for coordinating and managing water resources. Baguio City inNorthern Luzon, located 1500 meters above sea level, is home to 250,000 people (ADB,
2007). Tourists by the thousands drive to this mountain resort every year, adding to the city’s
problem of short freshwater supply. This proposed PDA will focus its institutional
development interventions in Baguio City, Philippines. The city faces problems withunaccounted for water aggravated by the growth of small-scale water suppliers andsettlements along watershed areas and presence of minerals that affect water quality. Attempts
at charting directions and investments to efficiently manage the water resources in Baguio
City have been initiated. In the regional and provincial plan documents, the role of Baguio
City is to protect and preserve watersheds within its territorial jurisdiction. In a separate reportcontaining the urban plan for Baguio, water issues were sketched under the infrastructurecomponent that tackled water supply, surface water sewerage, sanitation and sewage disposal.
This PDA hopes to enable Baguio city to shift from fragmented to integrated local water
agenda and action, to be catalyzed by an integrated management scheme at the local
government level. Specific targets for capacity-building are the city planning anddevelopment office as a coordinating and management office of the city government, and the
public utilities sector office that manages the water treatment facility. The expected results ofthis PDA are as follows:(a) an Integrated Medium-Term Local Water Operational Plan and Investment Priorities of
Baguio City; (b) a Cost-Recovery/Sustainability Plan for the City's Water Treatment Facility;(c) information and Communication Materials that Capture the Lessons Learned from theProject. This PDA assisted in the formation and design of a multi-sectoral, multi-functional,
and multi-lateral City Water Governance Committee (CWGC) for better and sustainable water
governance in Baguio City; and encouraged the participation of local governments andnational agencies in a seminar to disseminate lessons learned from Baguio City’s experience.
One of the main purposes of the AWDO 2007 is to focus the attention of national leaders andkey decision makers on the need to increase investments in the water sector if the MDG
targets are to be achieved by 2015. Although some countries have made good progress, others
need to make dramatic improvements as can be seen from Table 1. Nearly half of the targets
for 11 of the countries in the table will not be met by 2015. Simply providing access does notnecessarily mean all problems are solved and all benefits are received. For example, an
improved water supply must also provide good quality water delivered at the tap, andimproved sanitation must include effective waste disposal and wastewater treatment (ADB,
2007).

Food and Water Quality Management Programs at MMSU
Various academic institutions are actively pursuing studies on water quality management.
Their activities range from regular water quality monitoring to special studies on analyticalmethod formulation and/or validation and testing of substances to assess impacts on waterpollution and food product development to help local entrepreneurs. A GPS-guided survey forabout 250 food processors in Ilocos Norte were conducted by MMSU researchers to assess
their food processing and explore to improve their food products packaging and development
for food safety, use of clean water and enhanced their income (MMSU, 2007). At MMSU,
initiative is being done to conduct current good manufacturing practices (cGMP) on food andwater resources for crop production, dormitories, faculty houses and water refilling projects
for MMSU and for food processors of vinegar/wine, local sausage and other local foodproducts in the community. Moreover, WQMP is also being instituted in the university toprovide clean water for the community and for food processing. A water refilling station is
now being established as well as a mobile food and water packaging toll facility to help small
entrepreneurs in the rural areas to process their food products with clean water for foodproduct development and drinking water, for cGMP. As a continuing effort of the university,a team is assigned to monitor the water and food quality in the community, as well as
promoting water conservation techniques such as rainwater harvesting, growing drought
resistant crops and soil and water conservation measures.
The implementation of the Philippine Clean Water Act of 2004 by the DENR, other national
government agencies, LGUs, private sector, civil society, and other concerned entities requireappropriate planning processes, regulations, capital investments, and resources. It is evident
that more actions and resources are needed to build on existing water quality management-85-

programs. Due recognition should be made on the interrelationships and collaboration amongagencies and stakeholders responsible in addressing water quality problems. The framework
should pave the foundation for a cohesive direction, involving stakeholder participation
towards the implementation of various water quality management strategies. The active
involvement and participation of stakeholders should be enhanced in implementing water
quality management programs. It should promote a sustainable proactive approach to
managing water quality particularly at the local level. Successful water quality management
requires a strong community-based effort with diverse stakeholder involvement, good
partnership building with consensus, and effective and collaborative decision making on best
management practices. The challenge is to internalize the message that water is an importantresource and that everyone has to play a role in the conservation and management of ourwater resources.
Conclusion
Major water quality challenges that the country needed to improve the quality of its surface,ground, and coastal waters. The government should pursue aggressive strategic plans toaddress the seemingly decreasing trend of the quality of our water bodies. This implies safe
drinking and bathing waters and water bodies that foster production of our aquatic resources.
The active involvement and participation of stakeholders should be enhanced in implementing
water quality management programs. It should promote a sustainable proactive approach to
managing water quality particularly at the local level. Successful water quality management
requires a strong community-based effort with diverse stakeholder involvement, good
partnership building with consensus, and effective and collaborative decision making on best
management practices. The challenge is to internalize the message that water is an importantresource and that everyone has to play a role in the conservation and management of ourwater resources.

Abstract
Livelihood challenges of the communities in catchments area of and along the Hong Kaesemi-artificial drainage channel in Vientiane Capital, Lao PDR.
Wastewater in Vientiane Capital has drained to Nong Chanh Marsh. There are two main semiartificial channels, Hong Kae and Hong Xeng, functioned as gravitational drainage channels
connected between wastewater storage of Nong Chanh Marsh and the ecological wastewater
treatment system of That Louang Marsh, about over three Km length, before draining into
Mekong River at the South of Vientiane Capital at Houy Mak Hio River Mouth. The study
area is based water quality monitoring in the particular Hong Kae Channel, which is one of
the large channels in Vientiane that stores wastewater from the communities in the urban area.
There fore the objectives of the study are to: Monitor dynamic changes of water quality andtheir distinctions in different seasonal periods in one of the main drainage channels in
Vientiane Capital, Hong Kae; and Assess major economic and social impacts to somecommunities residing around Hong Kae channel. Methodology of the study is part of the
program on water quality monitoring and social economic impacts, for particular water
quality monitoring and impact analysis on Hong Kae Channel, the study team, Field survey
was conducted by preparing questionnaires and interviewing of representatives of 32
households, residing around Hong Kae area in 3 villages of Xaysetha District.
Based on household interview, 59.4% of interviewees used water from Hongkea for theiragricultural and fishery activities, while 40.6 % was never. From all of these interviewees,
87.5% of them claimed that wastewater created physically and mentally disturbance for their
daily lives. Within these, 93.8% claimed of bad odor, 56.3% of too much garbage, and 21.9%of less water. Most of interviewees reported that the serious wastewater disturbances started
from 2000.
According to the study in three periods as a model, it was analyzed that water quality status in
the Hong Kae Channel was terribly deteriorated, especially since 2002. This drove a numberof possible impacts to the communities as well as living things and ecosystem in thecatchment of and along the Hong Kae Channel. It is, therefore, recommended that relevantorganizations should pay their stronger attention for wastewater management in the Hong Kae,
as well as other channels in the Vientiane. These may include effective planning ofwastewater and solid waste management; intensive water quality monitoring and information
sharing; awareness campaigning on conservation of water resources, ecosystem andenvironment, basic hygiene and health care, and regular channel clean-up.

Vientiane is the Capital City of the Lao PDR at where about over 6 hundred thousand
inhabitants resided in its urban area. Wastewater in Vientiane Capital has drained to Nong
Chanh Marsh. There are two main semi-artificial channels, Hong Kae and Hong Xeng,
functioned as gravitational drainage channels connected between wastewater storage of Nong
Chanh Marsh and the ecological wastewater treatment system of That Louang Marsh, aboutover three Km length, before draining into Mekong River at the South of Vientiane Capital at
Houy Mak Hio River Mouth.
The study area is based water quality monitoring in the particular Hong Kae Channel, which
is one of the large channels in Vientiane that stores wastewater from the communities,
restaurants, markets, factories, hospitals in the urban area of Vientiane capital. The length ofHong Kae Channel form Nong Chanh to That Louang Marsh takes about 3,400 m. Before
2000, Hong Kae used to be irrigation channel supplied water from Mekong and Vientiane
flood water to the Northeast part of Vientiane, where the agricultural areas existed. These
agricultural areas have been narrowed due to the urbanization of Vientiane Capital. The
system was modified as domestic wastewater and Vientiane flood water transport andtreatment facilities. There fore the objectives of the study are to:• Monitor dynamic changes of water quality and their distinctions in different
seasonal periods in one of the main drainage channels in Vientiane Capital, Hong
Kae; and• Assess major economic and social impacts to some communities residing around
Hong Kae channel.
Methodology• The study is part of the program on water quality monitoring and social-economic
impacts, conducted by the Faculty of Environmental Science and Development,
National University of Lao PDR, which had been taken place in that Louang
Marsh and its draining channels during 2002 – 2008.
• For particular water quality monitoring and impact analysis on Hong Kae Channel,
the study team, included my self Oulavanh Sinsamphanh and Ms. Souksamone
Latsachanh, Bachelor Students of the Faculty of Environmental Science andDevelopment, National University of Lao PDR, was formed, for this particularpurpose.
• The study had been advised by Dr. Bounthan Bounvilay, Vice Director of Facultyof Environmental Science and Development, University of Lao PDR, and Mr.
Panya Simounkhoun, Lecturer of the mentioned Faculty.
• Field survey was conducted by preparing questionnaires and interviewing ofrepresentatives of 32 housholds, in which 65.6% was female and 34.4% was male,residing around Hong Kae area in 3 villages: Sysangvone, Hong Kae andPhonthan of Xaysetha District.
• Secondary data were also collected from reviewing the Water Quality Monitoring
Report in 2002 – 2003 of the Faculty of Science, Department of Chemistry, theNational University of Laos and the Study Water Quality of That Louang Swamp
Wetland by Integrated Physical-Chemical and Biological Factors, May 2004.
Accordingly, the data was analyzed comparing the values of some key water
quality indicators resulted in September and December 2002, and May 2003.
• Based on the results, conclusions and recommendation were conceptually prepared.

Results and Discussion
Chemical and Physical Analysis
In 2000, the Science Technology and Environment Agency issued a Decision on Wastewater
Management and Monitoring. The Decision set the classification of domestic effluent water
quality standards and Ambient Water Quality Standard. The aim of the decision is to set thefoundation for managing and monitoring of domestic wastewater and agricultural discharge
water quality. Numbers of applied parameters and their set standards are shown in Table 1.

Due to the study was to integrate physical-chemical and biological Factors for the morecomprehensive results as it would suitably be used for reflecting impacts from water quality
to the surrounding community. Therefore, some of the parameters applied for the study are
not included in the issued standard, eg. EC, DO, nutrients values of NH3-N, NO3-N, NO2-N, PO4-P,
Total-N, and Total-P. On the other hand, some parameters applied in the standards are not part of-89-

Based on seasonally periodical monitoring and analysis found that:









Rages of temperature were between 24.1°C and 32.6°C, in which the minimum
temperature was in December and the maximum is in May of the study periods.
Trends of water temperatures in the Hong Kae Channel were consistent to the seasonal
air temperatures, which was observably considered as normal condition;
pH values were ranged between 7.73 and 8.75, which were considered as minorchanges and still within the limitation ranges of issued standard;
Electrical Conductivity was ranged between 266 and 438 micro/cm. It was analyzed
that within the physical factors, distinctions of EC values were caused by theincreasing of dissolved solid ion in the channel wastewater in each season. This
reflected the increasing pollution in the channel and diluted by flow volume indifferent seasons.
Dissolved Oxygen in September 2002 (Rainy Season) had the highest value of 2.8
mg/L and dropped to the lowest in May 2003 of 1.1 mg/L. It was observed that ingeneral the average DO value in the three observed periods was lower than thestandard ranges (>2 mg/L). This was caused by high concentration of pollutant during
the low flow and high temperature period, which was consistent to the Oxygen
demand by bacteria for solving the increasing organic matters in the opposite directionof DO;
Bio Oxygen Demand values were changed based on seasonal measures. The BOD
value was at minimum level of 39 mg/L in September 2002 and maximum level of
78.3 mg/L in May 2003;-90-

− According to the analysis of DO and BOD values, which were considered asimportant factors for water quality monitoring in theological context, we canobserve that trends of these two parameters will change in opposite direction.
In each measure, BOD was increased while DO was decreased. It was foundthat BOD values extracted from each monitoring period were over thedomestic wastewater discharge standard, issued by STEA in 2000 (4 mg/L).
The results of monitoring of Ammonia Nitrogen in the three study periods had shown
that: in September 2002, the Ammonia Nitrogen values in September and December
2002 and May 2003 were 0.249 mg/L, 0.461 mg/L and 0.389 mg/L, respectively. In
comparing the three values, it was analyzed that the Ammonia substance caused a
considerable impact to aquatic ecosystem during and at the end of rainy season, whilehigh pH value in dry season caused relatively high Ammonia value and exceeded thestandard (Std = 0.4; pH > 7.5), which drove dangerous to aquatic reproduction process
in the Hong Kae Channel.
The results of monitoring of Nitrate Nitrogen in the three study periods had shown
that: the concentration of Nitrate in rainy season reached the highest value of 0.831
mg/L and lowest value in dry season of 0.455 mg/L.
The results of monitoring of Phosphate concentration in the three study period had
shown that: Phosphate values during rainy and the end of rainy seasons of 2002 anddry season of 2003 were 5.4 mg/L, 5.9 mg/L and 6.4 mg/L, respectively.

Generally, it was observed that trends of water quality in the Hong Kae Channel fromprevious up to date has been gradually deteriorated and drove more seriously impact to innerand surrounding environments, especially in the dry seasons when low flow and highpollutant concentration were occurred. It was analyzed that major influences to the water
quality in the Hong Kae Channel were the causes ofThe increasing number of population in nearby and within catchment area of thechannel as of urbanization and immigration. The building structures and domestic
sanitary and drainage systems in Vientiane including the study area were already poor
coupling with low environmental awareness of dense residential dwellers and newly
household community-scale businesses and industrial processing activities created in
the area who directly and indirectly disposed and discharged to the channel system;
More intensive agriculture practices in outer skirt of the urban area of Vientiane center.
Even though the agriculture land had gradually diverted to urbanity, however
agriculture waste was still one of the major sources of pollution in the whole drainage
system, including Hong Kae Channel. In order to improve the productivity, more
intensive agriculture was practiced which consumed more fertilizers and pesticides
were applied which drove more concentration of chemicals and fertilities in thedrainage system; andThe channel improvement project conducted by the Vientiane Urban Development
and Administration Authority. The project consolidated the channel from earth toconcrete structure which considerably reduced bioactivities and natural treatment in
the channel;

Social and Economic Impact Analysis
Based on household interview, 59.4% of interviewees used water from Hongkea for theiragricultural and fishery activities, while 40.6 % was never. From all of these interviewees,-91-87.5% of them claimed that wastewater created physically and mentally disturbance for their
daily lives. Within these, 93.8% claimed of bad odor, 56.3% of too much garbage, and 21.9%of less water. Most of interviewees reported that the serious wastewater disturbances started
from 2000.
Interviewee’s opinions regarding existing wastewater that 65.6% claimed relevantorganizations ignored sufficient wastewater management, 12.5% claimed industrial factories
discharged their used water without prior sufficient treatment, 65.6% claimed the wastewater
source from domestic discharges, 68.8% claimed the lack of environmental awareness village
communities due to the lack of awareness program at village and community levels, 12.5%
claimed some villagers / farmers applied chemicals for their agricultural practices, and 9.4%
claimed the use of pesticides.
Regarding time dimension of wastewater evolution based on the interviewee individual
observation, 78.1% reported water in Hong Kae Channel was in fresh condition before 2002
and only 9.4% reported water in the channel was remain fresh after 2002. Before 2002, only
34.4% reported their observation of dense domestic solid wastes in the channel, which
increased to 81.2% after 2002.
Another observation was that water weeds were rapidly spread throughout the channel, while
aquatic lives, e.g: natural fish, were reduced. Further more, there were common responses on
the impacts that some water-borne diseases occasionally spread in the communities, such as
diarrhea and cholera etc. 68.8% of interviewees believed that pollution in channel water
impacted their health through consuming vegetables from their gardens where they usedchannel water for irrigation, however actual residues has not been detected; 56.3% observedthat soil fertility was degraded; and 40.4% reported their gardening products were increased,
while 31.1% reportedly reduced.
Conclusion and recommendations
According to the study in three periods as a model, it was analyzed that water quality status in
the Hong Kae Channel was terribly deteriorated, especially since 2002. This drove a numberof possible impacts to the communities as well as living things and ecosystem in thecatchment of and along the Hong Kae Channel. It is, therefore, recommended that relevantorganizations should pay their stronger attention for wastewater management in the Hong Kae,
as well as other channels in the Vientiane. These may include effective planning ofwastewater and solid waste management; intensive water quality monitoring and information
sharing; awareness campaigning on conservation of water resources, ecosystem andenvironment, basic hygiene and health care, and regular channel clean-up.

Abstract
A potential of water resources in Myanmar is abundant for demand of agriculture production
and other sectors. Agriculture is a major economy of country so as to enhance irrigation
system for promotion of agricultural production especially for rice based system development.
After the construction of irrigation system, crop production can be promoted any time with anavailability of stored water in the reservoir in irrigation system. It is also urgently necessary toadopt more appropriate ways for generating the complex water resources project in Myanmar
to meet requirement of all sectors. At the same time, water conservation with appropriate
management and planning practices are also required in view of the rapid socio- economic
development of the country as well as for protection against water related environmental
degradation. The paper discusses the water potential in Myanmar, water resources utilizationand challenges, opportunities and threads in water resources development scheme, water
quality protection and its standard and government actions for pollution control, water sector
profile and international cooperation. In connection with technical and institutional bodies ofwater resources utilization should be adjusted to support for solving economic, social andenvironmental issues through successful implementation of IWRM.
Keywords: Water resources utilization, opportunity and threats, Legal and institutional frame
works, water quality protection.
Introduction
Myanmar is rich in water resources. The total utilization of the nation's water resources isonly about 5 percent or 45 million acre- feet (56 km³). It is clear that the physical potential forfurther development of water resources in Myanmar is substantial. Among them, thefreshwater resources are mainly used by the agriculture sector with small quantities being
used for domestic, industrial and other purpose. Due to the importance of the agricultural
sector, the Government has accorded high priority to its development, and numerous
irrigation facilities have been implemental since last two decades for irrigation and watersupply to monsoon and summer paddy crops. Apart from the agricultural sector, thehydropower sub-sector is also the most important in terms of economic development andinvestment. Moreover, dry-season irrigation, especially by use of river pumping project, hasbeen successfully increased as a result of power demand is also increasing annually. In fact
that, renewable hydropower generation is very important to contribute considerably to socioeconomic growth in country. Therefore, electric power generation projects are being
implemented wherever possible in order to meet the demand for electricity supplies.
At the same time, the Government is implementing plans for water conservation withappropriate management and planning practices so as to support for the rapid socio- economic
development of the country as well as for protection against water- related environmental
degradation.

Water Potential in Myanmar
Myanmar is geographically located between 9˚ 32' and 28˚ 31' North Latitude and 92˚ 10' and101˚ 10' East Longitude. It is characterized by mountain ranges in the north, east and west anda long coastal strip in the south and west. Lengthwise, it stretches about 1280 miles (2060 km)
north to south and approximates 587 miles (945 km) east to west thus leading to the area
coverage of 67.65 million hectares (676553 sq km) for the whole country. It has common
international borders with China in the north, Thailand and Laos PDR in the east, India and
Bangladesh in the west and again with Thailand in the south.
The water basin characteristics in Myanmar are quite variable due to the differences inphysiographic features. The principal water courses flowing separately in Myanmar comprisefour major rivers, the Ayeyarwady, Sittaung, Thanlwin., Bago and their major tributaries. All
rivers with the exception of the Thanlwin within Myanmar territory and can be considered
nationally own water assets. Their drainage area is spread widely over the country, amounting
some 876.73 million acre/ft (1,082 km³) of water volume per annum from a drainage area of
about 284,800 sq-miles (738,230 km²).
The monthly distribution of river flow vary according to the pattern of rainfall, ie. about 80
percent during the rainy season ( May- October) and 20 percent in the dry season( November- April). The estimated groundwater potential in Myanmar is about 495 km³ ineight principal river basins in Myanmar.
On the basis of stratigraphy, there are eleven different types of aquifers in Myanmar.
Depending on their lithology and depositional environments, ground water from thoseaquifers has disparities in quality and quantity. Out of these, ground water from Alluvial and
Irrawaddian aquifers are more portable for both irrigation and domestic water use. Howeveron the water scared regions, ground water from Peguan, Eocene, and Plateau Limestone
aquifers are extracted for domestic use.
Water Resources Utilization and Challenges
Myanmar is an agricultural country with an abundance of water resources. The agricultural
sector is the most basic economic of the state as well as the main source of livelihood in rural
areas, since the rural population represents some 70percent of the nation's population. At
present, the state has been systematically disseminating advanced techniques and support forthe development of the nation's economy. Dams are now irrigating more than, 1.7 million haof farmland. In addition to the dams, river water pumping stations, underground water tapping
stations and small dams have been built throughout the nation.
A total of 305 river pumping projects are irrigating about 188,000 ha of cultivated land. In
addition, 8136 numbers of tube wells have been provided to irrigate 48,000 ha of farmland.
Total irrigated area is increased up to 18% of the sown area in 2006-2007.
Tributaries originating in the western hill region and southern part of the country constitute
some 10 percent of the catchment areas and surface runoff. The hydropower potential of thesetributaries is considerable. According to studies by the United Nations and other sources, thehydropower potential of Myanmar is estimated to be as much as 41,000 MW. By 2008, 35hydropower stations ( including 15 medium scale projects had been completed with a total-94-

estimated generated power of 390 MW, which as almost 1 percent of potential generatedhydropower in Myanmar.
Moreover, the Development Affairs Committee under the supervision of the Department ofDevelopment Affairs (DDA) has implemented projects for sinking 15,715 no of tube wells to
supply drinking water for about 10,602 villages by using funds from the Government, the
DDA and donors from inland and abroad. The projects have been implemented withparticipation by international and non- governmental organizations.
The water sector faces some challenges including unusual and uneven rainfall patterns insome years, flooding and drought in some of the main agricultural areas of the country due toclimate change,, and also negative basically by the impacts of shifting and slash and burn,cultivation, illegal logging in watershed areas as well as management conflicts of interest andlack of coordination and cooperation within agencies. The most important challenges includes,(a) to strengthen the legal framework for ensuring the effective and harmonious
integration of water resources management, development and protection activities
into the socio- economic development process of the country.
(b) to enhance and consolidate of the existing systems(c) the operation, maintenance and rehabilitation of facilities safely, reliably andefficiently(d) to enhance organizational capacity and effectiveness of the water resources
coordination system.
Mission and Vision Statements
The mission statement for the water sector is to establish a beneficial framework and effective
mechanism for managing, developing and protecting water and related resources in anenvironmental and economically sound manner in order to meet the needs of the people of
Myanmar. "This statement is adopted by the Government and will provide a guiding lighttowards establishing national strategies for both short and long term efforts by all agencies,
people and stakeholders towards the common goals of national socio- economic development
and environmental conservation.
The vision statement of Myanmar is : Sustainability of water resources to ensure sufficientwater quantity of acceptable quality to meet the needs of the population in terms of heath,food security, economy and environment' and which clearly mentioned/ identified in
Myanmar Agenda 21 for more efficient freshwater resources management.
Opportunities and threats in water resources
A different kind of Water Resources Projects has been constructed throughout the country. It
consists of isolated and multiple- reservoir systems, ground water and river pumping projects,
diversion head- works and sluice gates for flood protection and saline water intrusion.
According to the country's agriculture base economic development policy, those
infrastructures were implemented especially for irrigation in conjunction with hydropower
generating for industrial and domestic water supply, and environmental sustainability.
Although Myanmar has abundant water resources and no scarcity of water at present, proper
management and a strong policy on sustainable and continuous development of the economy
and the conservation of the environment are required for the security of future generation.

-95-

And also to provide innovative and integrated solutions for sustainable management of water
resource to meet national developments.
Sedimentation is one of the major adverse effects of storage dams and in the lower courses ofrivers. Mining and deforestation along the upper reaches of river basins cause serious
watershed erosion problems, Transported sediment is reducing the storages capacity ofreservoirs and the bed level in the lower reaches of river is rising.
Flooding in the downstream of river and navigation faces serious problems. Although somenutrients and some sediment are needed to support the aquatic environment, the Government
is emphasizing the implementation of the terrace farming system to reduce shifting cultivation.
The development of industry and increasing population density will cause increasing demand
and also increasing river pollution and health risk for people living close to the rivers. Carefulmanagement of groundwater extraction is also required in order to avoid contamination ofarsenic.
Moreover, current legal and institutional frameworks also threaten to the water resources
development in Myanmar. Present organizational arrangements at the national and provincial
levels generally support the achievement of national policies, but the current institutional
problems in the water sector are mainly related to (a) weak of coordination and collaboration
between agencies within the sector and with those of other sectors and (b) inadequate
communication and coordination between the national agencies and authorities.
Despite the many Acts, Laws and regulations related to the water sector, should be amended
and reviewed with a view to enacting a unified water resources law in order to promote a
more effective legal framework for coordination and management of water resources.
Other weaknesses in the water sector are limited manpower, scare financial resources, and alack of appropriate monitoring facilities, proper and systematic record keeping and regularmonitoring and surveillance of water quality. As for water quality control, basic standards ofquality for drinking water were recommended in 1990, but have not yet been approved.
Anyway, joint efforts of the Government, local communities and NGOs, will be the key to thesuccess of water resources management programmes. Moreover, institutional strengthening,
capacity building and public awareness are essential elements of development work.
Water Quality Protection and Standards
The main courses of deteriorating water quality are sewage, solid waste industrial waste andagrochemical waste. For water conservation through water quality protection is undertaken byconcerned local City Development Committee. Actually, the control of wastewater is both amunicipal and industrial problem. In cities that are undergoing rapid industrialization , themunicipal treatment issue is complicated by the addition of untreated or semi treatedindustrial discharges into the municipal sewage system, thus stricter law to control the water
quality should be imposed. Mover over, there is still facing the problems of direct discharging
waste water from factories into the river or stream. Recently, NCEA ( National Commission
for Environmental Affairs) and NGOs propose effluent standard for proper disposal of waste
water from factions. By the way, it is seen that to disseminate the knowledge about the proper-96-disposal of waste water and public cooperation are essential to conserve the quality of natural
resources.
In agriculture sector, the government and ministry concerned has banned impact of sometoxic pesticides and encouraged utilization of conventional bio- fertilizer as a substitute forchemical fertilizer to mitigate the water quality deterioration. At present controlling of water
quality for various purposes are based on the WHO standard. Deforestation in the catchmentsarea and environ of water sources caused a serious problem of degradation water quality andquantity. It physically generates topsoil loss and land degradation by gully and sheet erosion
leading to excessive level of turbidity in receiving water and off- site ecological and physicalimpact from deposition in river and lakebed. And chemically, the silt and clay fractions, thecarrier of absorbed chemical, are transported by the sediments in to the aquatic system.
In order to control the quality of water resources, effluent quality standard of domestic waterand industrial waste water which are discharged on the land mass or discharged into water
body should be established.
In the current situation, concerned ministries and departments have organized a forum ofexpert on Water Quality issues. WHO proposed standard was adopted as a reference. Water
quality control measures were being taken as case- wise, especially for bottle drinking waterproduction. Arsenic and other parameters have been tested in collaboration with Water
Resources Utilization Department (WRUD), Department of Development AFFAIRS (DDA)and United Nation International Children Emergency Fund (UNICEF).
Laws regulation and legislation and legal support
Since the early 1900s, there have been established in laws, regulation, legislation and legal
support for water resources development, management and utilization in the water sector.
However, there is still needs that to be reviewed, improved and amended in line with IWRM
improvement for the sectors. The existing laws and legislations in the water sector and water
related sectors should be reviewed and, if necessary, new ones in line with national andinternational laws for IWRM should be added in the sectors.
Laws of Govern Pollution
In relation to pollution, Myanmar has no specific laws to govern water pollution. There is a
general provision in section 9 of the Public Health Law of 1972 which empowers the Ministryof Health to carry out measures relating to environmental health, such as garbage disposal,
use of water for drinking and other purposes, radioactivity, protection of air from pollution
and food and drug safety. However, detailed provisions do not exist to ensure more effective
and comprehensive regulation of these matters. In the regulation for hotels and tourism, there
are no provisions whatever for pollution control. Although the" Burma Ports Act of 1908"
contains a paragraph about harbor pollution, this merely focuses on the detriment tonavigation. The only control of water pollution in the country is through guidelines issued inJune 1994 by the Myanmar Investment Commission. These guidelines require that newinvestment projects have waste water treatment systems. River and Lake pollution fromsewage, industrial waste and solid waste disposal are serious problems in Myanmar, but are
not regulated explicitly by any laws, so new laws relating to pollution should be enacted.

Water sector profile in Myanmar
At present, Myanmar can be identified as low stress country concerning with water use.
However, Myanmar has now reached a major turning point in the use of water resources for
all-round development of the country. Several government agencies and departments under
different ministries are operating their own programs independently without proper
coordination with the principal executing agency.
In fact that, from fragmented sectors water resources management to a holistic integrated
management, Myanmar has to strengthen the capacity to undertake IWRM exercises,
developing projects in water supply, irrigation and hydropower without regard to theintersectional effects. Provision of the agricultural water is the first priority in water resourcesmanagement for the country at present and in the future as well. It was found out that about(91) percent of the water use was for agriculture, about (8) percent was for domestic
consumption and (1) percent was for industrial purpose.
International Cooperation
Myanmar becomes a permanent member of International Committee on Irrigation andDrainage (ICID) since 1982. MCID was established in 2001 and had formulated its
constitution in 2003 and actively associated with irrigation and drainage activities in theregion as well as international level. In 2003, Irrigation Department as a focal point agency of
Myanmar, cooperating with FAO and UNESCAP, had launched program to develop“Myanmar Water Vision” with a view to implement and realize the World Water Council’s
Water Vision. Moreover, this “Myanmar Water Vision” can become a basic guidelines andframework for the preparing of IWRM which is formulated by the year 2006 in Myanmar.
After that UNESCAP discussed with Irrigation Department ( ID ) to carry out Strategic
Planning Management (SPM) as the follow up activity.
Myanmar, former SEATAC member is actively participate in GWP-SEA activities andattended series of meeting and training program for upgrading awareness. Moreover,Irrigation Department as a focal point agency of Myanmar has close cooperation with otherorganizations such as WEPA, AQUGARINE, PWA, and INWRAF and so on.
Institutional bodies for water resources utilization
Several government agencies and departments under different ministries are engaged
independently both in surface and ground water use but the extent and type of water use aredifferent from one another.
Agriculture is the main sector of the utilization of water in Myanmar as water is very
important for cultivation of crops. The Irrigation Department is harnessing such resources, notonly concentrates in providing efficient increase irrigation for the development of the
agriculture sector, but also embraces objectives pertaining to adequacy of drinking water,
protection of environment and generating of hydro-electricity.
Water Resources Utilization Department also takes parts on developing water resources, both
surface and groundwater, for socio-economic development through provision of irrigationwater and drinking water.

-98-

Department of Hydroelectric Power Implementation is being the primary user of water for
power production. Public works, the Department of Development Affairs, City Development
Committees, and the Department of Human Settlement & Housing Development are
responsible for domestic water supply and sanitation works in urban areas and undergroundwater controlling works in Yangon City, while Department of Health taken care for the waterpollution and water borne diseases.
Department of Meteorology and Hydrology is responsible for measurement of discharges ofmajor rivers yearly to compute Runoff data for each stations and monitoring water quality atsome places.
Fisheries Department involve in water sector is to enhance food security conjunction withsustainability of mangrove ecosystem and conserving natural resources. Forest Department
also take responsible for the conservation and management of watersheds.
Watershed Protection
With the aim of ensuring sustainability of water resources of country, forests of Myanmar are
well conserved and safe guarded covering 50% of the nation will contribute to fulfill thehuman needs. Shifting cultivation and slash and burn practices provide significant
contribution to forest loss and at the same time, it can adversely affect the environment in a
number of ways such as soil erosion and degradation, deforestation, rapid silting ofreservoirs , rising of river bed, causing flood at the downstream and navigation problem, etc.
Therefore the government is making arrangement to reclaim the highlands and majorwatershed areas to substitute terrace farming for shifted cultivation.
In recent years a special programme has been launched by Forest Department for greening of
13 districts in central dry zone which is the most critical region in terms of degradation ofland conservation of forest and establishment of forest plantation as follows:
(a)

(b)

Plantation of fast growing multipurpose tree species at the rim and its
periphery of the basin boundary such as 50,000 trees for high dams, 40,000 for
medium dams and 20,000 trees for low dams to prevent watershed degradation
as well as to restore ecological balance.
Land rehabilitation and soil conservation activities in the most criticalwatersheds of upper Myanmar.

Concluding Remarks
Myanmar being an agro- based country; development of the agriculture sector is one of the
key factors that can spell the enhancement of people's economic life, living standard and foodsecurity. As water is the most fundamental requirement for agriculture, steps are being taken
to ensure that there is sufficient water for the cultivation of crops at the required time. The
construction of irrigation facilities meant not only for the agriculture purpose but also forgreening the environment, for supplying drinking water to local people and for generating
electricity wherever possible. In this case proper water resources management is important toensure the long term benefit and improved socio- economic life for farmers, the majority ofthe population.

-99-

It is also important to emphasize and disseminate new practices and farmers participation onfarm level for effective use of irrigation water. In Myanmar, several agencies are engaged
with supply and management of water. Lack of cooperation and coordination among water
related agencies is main issues for the proper management of water resources.
It is important for the enhancement of public awareness and public participation for successful
implementation of IWRM in the country. We would like to call on the stakeholders, national
entrepreneurs, and international organization to make concrete efforts to participate for thedevelopment of agriculture, livestock, and power and forestry sector in Myanmar.

-100-Role of MSMA in Promoting Sustainable Urban Drainage Systems in Malaysia
Md Nasir bin MD NOH, PhD
Deputy Director Urban Drainage Division
Department of Irrigation and Drainage Malaysia

Abstract
The Urban Stormwater Management Manual for Malaysia (MSMA) is a guideline publishedby the Department of Irrigation and Drainage Malaysia (DID) in 2000 to indulge the longterm nationwide directions and needs in ensuring sustainable urban drainage systems are fully
utilized. Concurrently, the Cabinet gave full approval and directive for this manual to bereferred and followed by every development project starting from 1st January, 2001. The
manual enables overarching issues like flash flood, excessive sediment outflow and water
quality deterioration generated by any land opening activities are controlled within its own
project boundaries.
The emphasis on the control at source techniques proposed by MSMA could be divided into
three main items, which includes water quantity control, erosion and sediment control, andwater quality control. Water quantity control is measures to curb post construction flash flood
problems while erosion and sediment control is measures to minimize erosion andsedimentation problems during construction stage. The final item, which is the water quality
control; measures intended to reduce post construction non-point source pollution problems.
This paper intends to scrutinize the evolution of MSMA as a focal urban stormwater
management guideline in Malaysia and share the milestones faced in promoting andimplementing it. The paper also elaborates some of the success stories achieved since the last
8 years of implementation while outlines some of the strategic directions and action plans
required to cushion any unprecedented debacles through practical and sound engineering
practices so that MSMA will hold itself as a prime reference in Malaysia for all stakeholders
i.e. the public and private sectors.
Keywords: Control at source, water quantity control, erosion and sediment control, water
quality control, enforcement activities and strategic directions
Introduction
Since 20 to 30 years ago Malaysia’s pace of development is unimaginable. Towering
structures, airports, highways and railways, massive industrial and housing estates are justsome parts of on going natural landscape alteration processes. With yearly precipitation
between 2000~3000mm, the degree of excess runoff generated from these areas is tremendous.
Flash flood, scenes of garbage flowing into rivers and silts generated from on going andabandoned construction areas are some common views causing severe damages to naturalriver system and its habitat.
To tackle these problems, the Government embarks programs like Clean Our River Campaign
since 1993 to discourage people from throwing rubbish in rivers, streams and drains; followedby the establishment and utilization of MSMA in Malaysia in 2001. In a matter of few years,
eco- friendly stormwater management facilities as proposed by MSMA become compulsory-101-yet popular among the public especially potential buyers. Value added infrastructures that
support the livelihood of urban community become future development trend. This induces
stormwater management facilities to be compulsory structures; proudly visualized among
various urban infrastructures.
Background
MSMA has been introduced as a replacement of the previous Urban Drainage DesignStandards and Procedures for Peninsular Malaysia, published in 1975. The manualemphasizes on control at source strategy with in depth explanation on water quantity control
and water quality control through best management practices (BMPs). Besides enabling all
new development areas to practice sound erosion and sediment control techniques through theimplementation of Erosion and Sediment Control Plan (ESCP), MSMA is also meant toensure peak discharge generated by extra runoff should align according to the downstream
river capacity. In this respect, the extra discharge to be released by any developed area should
be contained within that compound itself especially during peak flow. Once the flood recedes
the extra volume accumulated could be released towards the downstream section without
affecting the livelihood of the downstream community.
Immediately after launching, the 1st phase of MSMA focuses on the water quantity control
agenda where requirements are instilled within all Drainage Layout Plans submitted bydevelopers. Two (2) years later in 2003, the 2nd phase of MSMA was initiated where DID
started to promote the Erosion and Sediment Control Plan (ESCP) as part of Earthwork Plan.
In this respect, all development projects have to submit ESCP to ensure earthwork does notpose unnecessary threat to receiving water bodies. This is followed by the 3rd phase of MSMA
where post construction water quality control measures were emphasized utilizing treatment
control facilities like gross pollutant traps (GPTs), constructed wetlands, engineered
waterways, fat oil and grease traps (FOGs), infiltration facilities, bio-retention facilities,
sediment forebays, swales and etc.
Furthermore, DID as the focal department promoting MSMA initiates extra role throughretrofitting exercises to ensure rapid disposal facilities are converted to eco-friendly
stormwater facilities. This exercise involves heavy financial needs and investment; hoping by
2020 this program shall visualize its own and unique success stories. In terms of training andawareness, more than 10,000 stakeholders have attended conferences, seminars, workshops
and courses that are related to MSMA consists of professional like engineers, planners andarchitects from Government Agencies as well as consultants, developers and contractors.
Until today, DID still faces obstacles in promoting MSMA especially in terms of maintenanceof completed stormwater facilities. With more than 2000 detention ponds already constructedby developers, the amount of funds required for maintenance program is tremendous. To
avoid any negative perceptions, DID embarks special exercises where detailed cost benefit
analysis was conducted. Consequently, the economic analysis shows that these detention
ponds are saving billions of tax payer’s money due to the fact that without these stormwater
facilities, the public will have to finance more towards unnecessary flood mitigation works.
On the yearly basis, the ratio of saving is four to one (4:1).

Water quantity control
Stormwater management in Malaysia has traditionally focused primarily on managing theimpacts of flooding by adopting conveyance-oriented approach. Stormwater systems
designed in accordance with this approach provide for the collection of runoff, followed by
the immediate and rapid conveyance of the stormwater from the collection area to the point ofdischarge in order to minimise damage and disruption within the collection area. Stormwaterrunoff is viewed as a nuisance to be disposed of as quickly and efficiently as possible.
Until recently, stormwater management has developed to the point where there are now two
fundamentally different approaches to control the quantity, and to some extent, the quality ofstormwater runoff. In addition to the traditional conveyance-oriented approach, a potentiallyeffective and preferable approach to stormwater management is the storage-oriented
approach. The function of this approach is to provide for the temporary storage ofstormwater runoff at or near its point of origin with subsequent slow release to thedownstream stormwater system or receiving water (detention), or infiltration into thesurrounding soil (retention). This approach can minimise flood damage and disruption bothwithin and downstream of the collection area. Runoff may also be stored for re-use as asecond class water supply for irrigation and domestic purposes. The principal elements andtechniques used in a storage-oriented system are stormwater detention facilities and retention
facilities like on-site storage, community storage and regional storage.
Retention facilities are also utilised and designed to reduce the volume of stormwater runoff
from small frequent storm events by storing collected runoff and allowing it to infiltrate into
the surrounding soil. Retention is a suitable technique for infiltrating pre-treated runoff into
areas with relatively high permeability soils. Pre-treatment by filtering to remove coarse
sediment and debris is necessary to minimise blockage of the infiltration media. Regular
maintenance is also essential for their effective operation.
Water quality control
The primary objective of stormwater quality control is to achieve good water quality
standards released from completed development project. The activities outline in this programis based on three types of best management practices (BMPs).
Housekeeping BMPs: Housekeeping BMPs are techniques that aim to change humanbehaviour to reduce the amount of pollutants that enter stormwater systems by targeting thecontrol and/or prevention of pollution at its source. These techniques are:• community education and participation activities;• management activities, such as landuse planning and development control;• operations and maintenance activities, such as garbage collection and street sweeping,and• improved site planning and management.
Source Controls BMPs: Source controls BMPs are those practices that tend to keep both
runoff and pollutants contained at their source. These include pervious areas and buffer strips
towards which runoff is directed, infiltration controls, porous pavement, erosion and sedimentcontrol plan (ESCP), which include the submission and compliance to the approved plans andetc.
Treatment Controls BMPs: To protect the quality of local streams, lakes, and river systems,
a number of treatment controls BMPs may be adopted as follows:-103-• the establishment of lakes, primarily as biological treatment systems;• the utilisation of water quality control ponds and wetlands, as physical and biologicaltreatment systems, upstream of lakes;• the incorporation of gross pollutant traps on inlets of lakes and water quality control
ponds and wetlands to intercept trash and debris and the coarser fractions of sediment,and• the incorporation of 'off-stream' sediment basins into land development to intercept(and chemically treat if necessary) runoff prior to its discharge to stormwater systems.
Erosion and sediment control
Erosion and sediment control (ESC) activities during construction works is based on the
preparation of Erosion and Sediment Control Plan (ESCP). Accordingly, six principles of
ESC are governed, which include 1) Planning Considerations, 2) Vegetative Stabilization, 3)
Physical Stabilization, 4) Diversion of Runoff, 5) Flow Velocity Reduction, and 6) Sediment
Trapping/Filtering. Some of the ESC measures outline in the ESCP are topsoil stockpile,
preserve vegetations, seeding and planting of vegetations, mulching, stabilization, earth bank,diversion channel, slope drain, outlet and inlet protection, check dam, sediment fence, sandbank barrier, brush or rock filter, sediment trap and basin.
The utilization of ESCP for developed areas becomes compulsory since October 2005 after
being endorsement by the National Council for Local Government. In short, every
development project that is more than 1 hectare has to submit ESCP and Earthwork Plan
together to DID to be reviewed and endorsed before approval is given by Local Authority. For
area that is less than 1 ha, ESC measures shall be put straight away inside the Earthwork Plan
allowing small scale development to skip full ESCP submission.
Enforcement activities
Model study conducted in the State of Selangor since 2005 shows that enforcement activities
need to be addressed collectively by various Agencies steered by strong political commitment.
Current legislation like Street, Drainage and Building Act (SDBA) has been used in Selangoremphasizing on polluters pay policy. Until the middle of 2008 more than RM15 million
compounds have been collected by Local Authorities from developers that failed to comply
ESCP requirements e.g. poor earthwork controls. Since the success of the program in securing
clean runoff water, the Federal Government has approved its utilization for the entire nation in
August 2008 through the endorsement obtained from the National Water Resources Council.
Future success of this program is vital to ensure developers, contractors and consultants arealigned with national strategic stormwater programs.
Strategic directions
Under the Vision 2020, Malaysia is targeted to be a developed nation. The current manual
paves the way for a nation to achieve its vision through a sustainable fashion. To ensure
achievable goals, the strategic direction was set especially to examine existing problems arise
among stakeholders and streamline specific actions that should be taken by decision makers.
The National Stormwater Management (SWM) Goal – “Stormwater shall be managed so thatit contributes towards sustainable development of the country”. The strategic direction is-104-

divided into three areas 1) SWM infrastructure asset, 2) Stormwater and related eco-system asa resource, and 3) Stakeholders and users of the resource and the SWM infra asset.
SWM Infrastructure AssetTo develop a world-class SWM infrastructure accompanied with an equally world-class O&M
to achieve an efficient, safe and eco-friendly SW management system. World-classinfrastructure shall embody the contemporary best practices and technologies benchmarked
against those found in developed countries. Strategies related to this program are i) upgrade
existing infrastructure, ii) improve operation and maintenance, iii) improve development
planning and control, iv) address point source pollution, v) tighten regulatory andenforcement, vi) knowledge and development and vii) training and education.
Stormwater and Related Eco-System as a Resource
To have an equitable, beneficial and sustainable utilization of the resources. The resources
may be utilized as alternative source for non-potable use in urban areas, allow recreation,
conducive to tourism and as a source for water supply and for the eco-system. This program
elaborates on i) establish policy on stormwater utilization, ii) promote stormwater througheducation with strong provision on resource control, and iii) strengthen legal aspects.
Stakeholders and Users of the Resource and the SWM Infra Asset
To promote effective stakeholder participation towards the development of stormwater
facilities and environment while at the same time benefiting from their proper use. This
program emphasizes on i) education, ii) improve framework for public participation, and iii)
improve regulatory and enforcement.
Way forward
Stormwater management is a continuous process involving various stakeholders. Future
activities that up hold the strategic directions need to be addressed tactfully to ensure MSMA
continuously indulges Malaysia in becoming a developed nation by 2020. Among important
future activities are establishing the Total Maximum Daily Loads (TMDL) in various
catchments, tax incentives initiatives for developers and investors that fully complied MSMA
requirements and revision of the existing manual and guidelines to include additional needs
like climate change.
In terms of providing adequate experts to fulfill the knowledge gaps, capacity building
programs embarks by DID shall focus on training and accreditation exercises. Consultants,
contractors and site supervisors shall be required to attend and pass certain minimum
standards before being allowed to submit drainage and ESC plans. The program also ensurescompetent consultants responsible for the design while competent site supervisors handle site
supervision works. Most of the training courses conducted by DID nowadays focus on hands
on programs so that the level of knowledge increases according to the current and futureneeds.
Conclusions
Stormwater Management Program especially in urban areas is vital for a developing nation.
Spearheading by “VISION 2020”, stormwater program in Malaysia is moving forward
towards streamlining the strategic direction into strategic action plans. Most of developed
nations have developed their own National Stormwater Management Framework complete-105-with their vision, mission, objectives, targets and strategies. Some countries have succeeded
their short, medium and long term programs to the extent of full scale strategic action plans
implementations.
In its 8th year of implementation, MSMA has evolved into a main stream guideline to ensure
nation building programs fulfill sustainable development agenda as required by various
international standards and signatory bodies. Malaysia is committed in promoting sustainable
development and it is obvious that MSMA achievements set clear directions; thus, filling thegaps created by our ancestors while provides hopes for our children to inherit.
Malaysia still has a long way to go in getting full success in this program. The basic
foundation for eco-friendly urban stormwater management program has been launched morethan 5 years ago. With more than 12 years to go before reaching the year 2020, it isindispensable to strengthen this effort by exercising coordinated and integrated management
approaches among relevant Agencies to ensure all requirements are fulfilled at the stage ofpre-construction, during construction and post construction. Consequently, the targets forhigher quality of life through sustainable development could also be achieved concurrently
without compromising the environmental needs.

Abstract
About 2 decades after "Renovation", Vietnam economy is developing remarkably; beside fast
economic growth, it is the fact that all river basins in Vietnam are now facing pollution
problems. Among many river basins in Vietnam, Cau, Nhue-Day and Dong Nai basins belong
to the most polluted group. The river water is polluted with organic compounds, oil,suspended solids, etc, since untreated wastewater is often discharged freely into the rivers
from cities, towns, industrial zones and craft villages. The pollution is threatening health of
the basins' residents. Some efforts of Vietnam on improving river basins' environment
management were presented.
Keywords: River basin, Cau, Nhue-Day, Dong Nai, water quality, pollution
River basins in Vietnam: An overview
With 13 large river systems, which cover 10,000 km2 in total, Vietnam is considered to havea complex and dense river network with most of the large river systems linked. Amongst
those 13 main river systems, 9 have basins which contribute to 90% of total river basin area inthe whole country. The 9 main river basins are those of Red, Thai Binh, Bang Giang-Ky Cung,
Ma, Ca La, Thu Bon, Ba, Dong Nai, and Cuu Long river. The Red river and the Mekong river
systems have the largest basin areas (155,000 and 795,000 km2 respectively) as well as thehighest total volume of water flow. Other than that, each river system has its own distinctive
characteristics, thus environmental management approaches may vary greatly from one river
basin to another, depending on socio-economic conditions, land use, environmental factors,
and their economical and ecological values, .etc.
In this short review, 3 river basins chosen to focus on are of the Cau, Nhue-Day and Dong Nai
river. The Cau river, a large river of the Thai Binh river system, is 288 km long and passes
through Bac Kan, Thai Nguyen, Vinh Phuc, Bac Giang, Bac Ninh, Hai Duong provinces andHanoi before it merges with Thai Binh river. The whole river basin area of Cau river and its
branches is originally rich in natural resources such as forests, minerals, etc. However, thosenatural resources have rapidly depleted together with the economic growth of the provinces
along the river. Many human activities such as mining, agriculture, establishment of craft
villages, ...continue to add more pressure on the natural resources. Moreover, the population
density of the Cau river basin is twice as high as the average population of Vietnam (427 perkm2) and is unevenly distributed between the rural and the urban areas. Although the GDP ofthe provinces along Cau river has recently rise up, there is a reduction in environment
condition here.
Nhue-Day river system includes Day river, which is linked with the Red river but has its own
basin with tributary rivers such as Nhue, Tich, Thanh Ha, etc. The Nhue-Day river basin-107-

(7,665 km2) stretches from the mountainous Ha Tay, Hoa Binh provinces to Ha Nam, andfinally to the coast Ninh Binh, Nam Dinh provinces. After dam construction and reform, theDay river (237 km) is now a draining river and serves to diverge floods in the rainy season.
The Nhue-Day river basin, which mainly is plain, creates many advantages for building andeconomic development. In addition, many branches (Tich, Thanh Ha, Hoang Long river) flow
through towns, cities and industrial zones and provide important water sources for agriculture
and industrial production. Again, the population density of the basin is about 3.5 times higher
than the national average, with most of the population concentrates in Hanoi, Ha Tay andNam Dinh. In recent years, the expansions of big cities like Hanoi and Ha Tay, together withthe spreading of residential areas, industrial zones, and craft villages have brought up the
GDP of provinces along the Nhue-Day river system. At the same time this economic
development has put the river environment in great danger.
Different from the 2 river systems described previously, Dong Nai river system flows in thesouth Vietnam and passes through 11 provinces and cities in total. That includes HCM city,
Lam Dong, Binh Phuoc, Binh Duong, Tay Ninh, Dong Nai, Dak Nong, Long An, Ba RiaVung Tau, Binh Thuan and Ninh Thuan provinces. The river basin covers an area of 14,800
km2 and has 266 rivers and streams of over 10km each. The Dong Nai basin system is reachwith minerals resources such as gold, iron, tin, zinc, etc. which are being exploited rapidly.
Besides mineral resources, this basin system is also covered by tropical forests with a great
biodiversity of tropical ecosystems. These forests also protect the area from flash-flood in therainy season and maintain water lever for Dong Nai river in the dry season. However, fasturbanization in the basin and the high growth rate of the population have contributed togradual deforestation. Although the basin has a rapid economic development and urbanization,
the environment is concerned and protected to an extent. As a result, this is considered one of
the economic development regions which have achieved fast and sustainable economic
growth.
The current state of Vietnam river basins pollution
After the Renovation, Vietnam has been developing nonstop in economy. However, thiseconomic development is faster than the establishment of the infrastructures. As a result,
growth puts increasing pressure on the environment in general. The river systems’
environment also shares the same fate; many reports have described the dramatic decrease ofriver water quality and the high concentration of various toxins in the water. The level ofpollution varies among different river systems and also among different parts of one system.
In this part, the particular situations of the 3 concerned river basin systems are described
separately.
In general, the surface water of Cau river is locally polluted by organic pollutants, suspended
solids and oil waste. In the section passing through Bac Kan province, the river is polluted
heavily with BOD5 and suspended solids. The part flowing through Thai Nguyen city isprobably polluted the most, due to the untreated waste water released by heavy industrial
factories, paper mill, mining (gold and coal mining) and agriculture activities along the river.
Pollutants in this part of Cau river are mainly organic compounds (eg. Nitrogenous
compounds) and oil compounds which give the river a distinct oily smell. The river section
from Vat bridge to Pha Lai has been severely polluted with organic substances and the levelof pollution becomes far higher than the permitted standard. This organic pollution wascaused by waster water from domestic, urban and tourism activities as well as oil pollutants-108-from industrial waste. Moreover, this part of the river system has many craft villages
established along the bank. These villages mainly focus on food processing, animal husbandry,
paper recycling, scrap recycling, metallurgy, etc. and waste water is often discharged directly
in to the river.
In comparison to the Cau river, the Nhue-Day river basin is facing an alarming level ofpollution caused by the release of waste water from domestic, industrial, agricultural andaquaculture activities. In the case of the Nhue river, since the To Lich river heavily polluted
water mixes with the Nhue river, the section flowing through Ha Dong of Nhue is tainted with
COD and BOD5 at a level 4 times higher than the standard. The Nhue river after the
confluence point with To Lich has water darken with scum, sludge and has a fishy smell. Thiscondition only worsen in the dry season as the pollutants are less diluted. Moreover, thepollution of the Nhue river causes a chain reaction which leads to pollution of the Day river,since the 2 rivers are linked. The section of Day river from Ha Dong to Phu Ly town is mainly
polluted with organic substances; however, the flowing section to Hoang Long suffers fromboth Nhue river’s pollutants and waste water discharged from Phu Ly town. To sum up, theNhue-Day river basin is one of the most polluted basin systems in Vietnam with domestic
waste water contributing 56% of the river total volume.
Similarly to the 2 described river basins, the Dong Nai river basin is also severely affected bypollutants resulted from fast economic growth with little regard to environmental issue.
Especially, the downstream section of Dong Nai is heavily polluted with organic, suspended
solid substances and has lead concentration few times higher than the permitted limits. The
water downstream is also seriously salinized to the point that can not be used for domestic andagricultural purposes. In the part of Sai Gon river system, rivers are severely polluted withorganic pollutants (eg. N-NH4+ level is about 30 times higher than VN standard), coliforms(3-168 times higher than permitted limit) and heavy metals (eg. Fe content in Be river: 10-12
times higher than VN standard). The most critical case is Thi Vai river, which is highly
contaminated with mercury, zinc, organic compounds, etc. With this severe pollution, almost
all species are unable to survive and the river is now a dead river.
Water quality management
As described in the previous parts, many of the river basins in Vietnam are now sufferingfrom heavy pollution level. Therefore, protecting the river basins’ environment is a crucialpart in water resource management. However, water quality management in river basins
meets many difficulties. They include the unclear definition of responsibilities andcompetences among ministries and sectors; the lack of mechanism to acquire resources fromprivate, non-governmental, international organizations and communities in water resource
protection, etc. Recently, environmental legislation has been adapted by the Vietnamese
government to support the water source protection. Some of the most important laws are theLaw on Environmental protection (2005), the Water resource law (1998), the Land law (2003)
and Systems of Vietnamese Standards – river/lake water quality standards. Although, theenvironmental legislation has provided the activities of water resource protection a legal
ground, the application and implementation of those laws are still limited and inadequate.
Water quality management of the river basins is separated to 2 levels. In the national level, theMinistry of Natural Resources and Environment (MONRE) was established in 2002 with themain task of preparing master planning on water resource protection, management and use in-109-the principle river basins. With this task, the MONRE has promoted institutional preparationfor effective water management and submitted to the Government for issue. In addition,
MONRE has also contributed many guidelines for environmental legislation improvement. At
the regional level, the provincial Departments of Natural Resources and Environment(DONREs) have been established. Therefore, the water quality management started withfocusing at the localities. However, these local organizations have no common voice, unity or
close cooperation in water resource management, thus their activities still have little effect on
improving the river basin environment. Some of them even have the wrong concepts ofenvironmental protection purposes for the river basins and their responsibilities in organizing
environmental protection in the local river basin.
Another important step in water quality management is examination and inspection. This is an
important action to ensure that the environmental laws are being obeyed and protect the river
basins of the illegal waste water discharge from industrial zones, craft villages and domestic
uses. The importance of this step has been emphasized by the incidence of Thi Vai river,where Vedan company had illegally released untreated waste water for 14 years before being
exposed earlier this year. Even though this release of waste water has been stopped but Thi
Vai river has turned to a “dead” river which will take billions to restore its water quality.
These billions would not be wasted if only the illegal activities were discovered earlier. The
inspection can be periodic or spontaneous; also there are insitu inspection in which theindustrial zones and establishments analyse their own environmental conditions and exsitu
inspection carried out by MONRE and/or DONREs. The inspection activity also helps
identifying the economical activities which release the most contamination into the river
basins, as well as companies causing serious pollution and ones having environmental
friendly practices. From the result of inspection and examination, legal activities can beapplied to establishments which purposely breach environmental laws and adjustment would
be considered to ensure a sustainable economic development in Vietnam river basins.
However, in fact both water quality management planning and inspection activities are limited
since the environmental protection organizations’ lack of man power and financial resources.
Moreover, the environmental legislation is still developing, and needs years of experimentand correction to tightly regulate the activities of water resource management.
Some priority solutions to protect the water environment of river basins in Vietnam
As mentioned in the previous parts of the report, the level of pollution in river basins isincreasing rapidly together with the fast growth rate of the economy. In this situation,
preventing increased pollution and restore the polluted rivers to their previous condition areurgent tasks. The common solutions for these tasks are improving legal regulations,management and inspection activities, cleaning technologies and public awareness. Firstly,
the law on water resources are needed to be revised to give clearer definition of
responsibilities and coordination mechanisms between central and local authorities, among
ministries and among local governments of provinces in one river basin. Moreover, anenvironment protection mechanism for one particular river basin with clear indication ofenvironmental problems and provision of codes of conduct for relevant parties should bestated for every river basins. In addition, the inspection and monitoring system should be
strengthen. Not only the enterprises that cause serious pollution are carefully investigated, theestablishment of potential new pollution sources should be strictly banned. The governmentalorganizations have to carry out regular environmental inspection and investigation; moreover,the government should encourage the enterprises to implement self-monitoring programs and-110-regulations according to the Law of Environmental Protection (2005). Beside the industrial
zones, the local water environmental protection organizations should cooperate to give carefulmeasurements of pollution generated urban domestic activities. The fees on waste water
discharged should also revised and issued basing o the principle “polluters pay”. The finecollected would then be invested on improving environmental technologies as well as man
power in environmental protection organizations. Public awareness is an important part in
improving the water environment protection. As the residents in the river basins aware of theconditions of the basins and how that affects their lives, they would be more responsible andparticipate in protecting the surrounding environment.
In the particular cases of the 3 river basins concerned in this report, the solutions are more
specific regarding the different conditions of the 3 basins. For Cau river basin, the immediate
action should be to treat waste water released from industrial and mining activities in Bac Kan
and Thai Nguyen, waster water from Bac Giang and Bac Ninh craft villages and domestic
waste water from cities along the basin. The most serious polluted areas in the basin should be
more concerned and controlled and investment permits for industrial activities such as mineral
exploitation and paper pulp production should be strictly limited.
In Nhue-Day river case, the treatment of domestic waste water from Hanoi and other cities
should be focused on. Moreover, a strict control should be applied to severely polluted areas
such as To Lich river. In this basin, 5 industrial types that threaten the water environment(cassava starch processing, basic chemicals production, dying, leather tanning and paper pulp
production) should be carefully considered before permission.
Finally, in Dong Nai river basin a similar treatment of domestic waster water should beapplied not only to HCM city but also to other cities in the same basin. Several heavily
polluted areas like Thi Vai river, Sai Gon river, Tay Ninh canal, etc. should also be strictly
controlled like in other basins. However, there are 5 industrial types that should be temporary
banned from this river basin instead of limiting like in others. They include cassava starch
processing, rubber latex processing, basic chemicals production, dying and leather tanning. At
the same time, there are 5 other industrial types whose investment permission should be
limited. These are plating industry, fishery processing, agricultural chemicals production andfertilizers production, and paper pulp production in Thi Vai river basin.

Water Quality Monitoring and Water Quality Situation in Thailand
Thiparpa Yolthantham
Director of Inland Water Division
Pollution Control Department (PCD)

Thailand can be divided into four main geographical regions: the North, the Central Plains,
the Northeast, and the South. The North is mainly mountainous which serves as the origin of
four major rivers (Ping, Wang, Yom, and Nan) which converge to become the Chaopraya
River, the lifeline of the Central Plain. The South covers a number of short rivers and coastal
areas. The Northeast occupies one-third of the country’s total land area and is the mostpopulous and lowest income region. Large parts of this region regularly experience standing
with periods of floods and alternating with periods of drought. In term of geographic feature,
there are total 25 river basins in the country. The side of the basins is difference from basins
to basins.
The results of water-quality monitoring program showed that most receiving waters were still
compiled with the national water quality standards. However, rivers in populated areas were
polluted due to the excessive discharges of wastewater from various point sources. Thus,
mitigation measures such as construction of wastewater treatment plants, solid waste
management, agricultural waste management, industrial waste control, and management ofother pollution sources are required.
In Thailand, water pollution from land-based activities is largely associated with urbanization,industrialization, and agricultural activities. Thus, the major sources of pollution are domestic
sewage, industrial wastes, and agricultural wastes. The main pollutants that pose to natural
water quality problems are organic wastes, bacteria, nutrients, and other chemical substances.
Observation of water quality for the receiving waters was carried out in terms of dissolved
oxygen depletion, fish kills, high ammonia nitrogen, high coliform bacteria, and occurrence ofeutrophication phenomena. The major impacts of water pollution are the deterioration ofwater supply sources, effect on aquatic ecosystem, and public health. As a consequence,sources of water supply become scarce whereas the demand is rapidly increasing. The
surveillance and monitoring program of receiving waters are therefore very important toassure the good water quality status for aquatic ecosystem as well as protection the humanhealth effect.
Water Quality Monitoring
There are many water quality variables that causes water pollution problems, such as BOD,
nutrients (nitrogen and phosphorus), toxic substances, bacteria, and solids. There are total 28
variables in the National Surface Water Quality Standards. Surface water quality weresurveyed and designed for monitoring program. The program has been implemented since in1980. Sampling stations were identified into two sources: surface and ground waters. There
are totally 368 station s in 48 river in the country. Water quality samples were taken 2- 4
times a year covering wet and dry seasons. Water quality parameter measured were physiochemical parameters (pH, turbidity, conductivity, total suspended solids, total phosphorus,
total solids, biochemical oxygen demand (BOD), dissolved oxygen (DO), nitrate-nitrogen,heavy metals), and biological parameters (fecal and total coliform bacteria).
-112-

The method of water sampling and analysis procedures were followed the Standard Method
for the Examination of Water and Wastewater (1998). The quality assurance/quality control(QA/QC) was also performed during the analysis.
PCD has also operated 28 automatic sampling stations along major rivers in the country. The
water quality information can be measured using continuous real time system. Each station
measure only basic water quality variable such as temperature, pH, conductivity and DO.
Water Quality Standards
The ambient water quality standards has been established since 1994 and served as guidelinesof supposing the receiving waters based on major beneficial uses. The surface water quality
standards are classified into 5 classes as follows:
Class 1: Extra clean for conservation purposes
Class 2: Very clean used for (1) consumption which requires ordinary water treatment
processes (2) aquatic organism conservation (3) fisheries, and (4) recreation[DO > 6 mg/L, BOD < 1.5 mg/L, Fecal Bacteria < 1000 MPN/100ml)
Class 3: Medium clean used for (1) consumption but passing through an ordinary
treatment process and (2) agriculture [DO > 4 mg/L, BOD < 2 mg/L, Fecal
Bacteria < 4000 MPN/100ml)
Class 4: Fairly clean used for (1) consumption, but requires special treatment process
and (2) industry [DO > 2 mg/L, BOD < 4 mg/L)
Class 5: Waters are not classification in class 1-4 and used for navigation
The details of the National Surface Water Quality Standards are shown in Appendix.
Water Quality Situation
The main pollutants that pose to water quality problems are organic wastes, bacteria, nutrients,and solids especially in the lower parts of the central river basins. The water quality has beenless than the Surface Water Quality Standard and its classification. The major water quality
problems were high coliform bacteria (in term of total and fecal coliform bacteria, 34 %),high solids (in term of turbidity and total solids, 31 %), total phosphorus (TP, 15%), lowdissolved oxygen (DO, 12 %), Ammonia-nitrogen (NH3-N, 6%), and high organic matter (interm of biochemical oxygen demand (BOD, 2 %), as shown in Figure 1 and 2 (Simachaya,2002). Generally speaking, these problems were perceived to be most serious during summer
low flow periods when there is minimal dilution capability available.
Water Quality Policy
The National Economic and Social Development Plan for 2007-2011 and the National
Environmental Quality Plan for 2007-2011 continue to emphasize the rehabilitation of natural
resources and the environment by strengthening environmental management and increasing
local and community participation. Under the plans, policies for water environment aim toaccelerate the rehabilitation of water quality in major water resources, to reduce and control
water pollution originating from domestic, industrial, and agricultural activities, to apply thepolluter pays principle, and to promote and support private sector investment in solving waterpollution problem. The goal of water quality of the water bodies in the country was set up tocomply with the ambient water quality standards under fair and good condition of not less-113-

than 85 % of water bodies in the country. Under those plans, area approach for water
resources management is concerned. This should be integrated water quantity, water quality
and relate resources as a whole basin or a boundary of geographical area. The best practices
of water quality management in developed countries are implemented under basin approach.
The approach is included the following step: (1) identifying basin uses, (2) setting appropriate
water use and water quality targets, (3) determining the current “state of the basin”, (4)identifying specific issues and management options, and (5) developing a process for public
consultation (Heathcote, 1998).
In Thailand, there is no such integrated approach applied to water environment management
since 2000. The management has been separated between the quantity and quality of water
due to agency responsibilities and their respective regulations. For major rivers in the country,
observed water quality problems were dissolved oxygen depletion, fish kills, high ammonia
nitrogen, high coliform bacteria, and eutrophication phenomena. Generally speaking, these
problems were perceived to be most serious during summer low flow periods when there isminimal dilution capability available and first flush of high flow periods. Thus, once water
quality problems have been identified, it is necessary to develop targets for restoration toundertake the planning exercise on a basin-wide basis (Wijarn, 2000). The strategy and planshould identifies key areas for water quality improvements as well as a framework of actions
for interested stakeholders, including: (i) ensuring better environmental governance throughinstitutional restructuring, compliance, and decentralization; (2) introducing a sustainablefinancing mechanism, i.e Polluter Pays Principle; (3) promoting more active community
participation in water resource management ; (4) improving waste and wastewater
management in large cities in the country; and (5) improving water environment of the majorriver basins (World Bank, 2002).
Management Approaches and Implementation on Water Quality
Command and Control
Command and control is usually normal approach to control waste discharges from point
sources of pollution which is based on European and American pollution control models. In
Thailand, this model has been implemented with the establishment of effluent standards andtheir subsequently enforcement. The lists of parameters and values of each parameter of
effluent standards can be found at http://www.pcd.go.th/. Number of effluent standards frompoint sources of pollution have be established such as factory, industrial estate, building, pigfarm, gas station, and shrimp pond. The size of point source pollution has also been classified
and implemented the effluent standards. From the results of monitoring the discharges by
PCD, some point sources have not been complied with the effluent standards especially fromagricultural activities. Thus, PCD is currently developing a compliance assistance centre toassist the polluters. The pilot program has been established for pig farm.
Wastewater Treatment and Disposal
The Government of Thailand has made slightly progress in collection and treatment of urban
wastewater over the past decade compared to other countries in the region. Wastewater
management services are currently provided by the local government authorities, although-114-

agencies of the central government play the dominant role in sector planning and funding.
Under investment in environmental infrastructure is clearly evident in the municipal
wastewater management sector. Only a small proportion of total urban wastewater generation
presently receives any treatment. At present, Thailand has 95 central wastewater treatment
plants installed in large communities and major tourist attractions. The 70 treatment plants,
total capacity about 1.13 million m3/d, are in operation, total capacity about 1.87 million
m3/d, are now under rehabilitation and construction. These facilities will finish within theyear 2008. As a result, the estimated total capacity about 3 million m3/d of wastewater orapproximately 21% of total generated domestic wastewater in Thailand (14 million m3/d by
2003) will be treated properly before discharging into receiving water. However, there arestill large amount of untreated wastewater drained into the environment causing many vitalwater sources to gradually deteriorate.
Although, the government’s achievement in addressing urban wastewater management in the
country are praiseworthy, there are many problems behind that such as wastewater fee
collection, operational and maintenance the facilities, efficient technical staff, and nonfunctioning equipment. The main problems have been identified as the poor performance inoperating and maintaining of wastewater facilities due to the lack of funding and suitably
qualified staff. However there are still difficult political and social obstacles to be overcomein the introduction of effective, sustainable funding of wastewater facilities, including theperceived low willingness for beneficiaries to pay for wastewater services and the general
unwillingness of the water supply sector to combine collection and billing of charges forwater supply and the resulting wastewater. Currently there are three local organization
authorities utilizing the wastewater tariffs and a few more are working toward the idea. Dueto the economic crisis in Thailand and problems of the large central treatment facilities inSamut Prakarn, implementing wastewater treatment facilities have been reduced.
For industrial source, there are more than 120,000 factories and about 30 industrial estates inThailand. Industrial wastewater management services are mainly undertaken and funded byindividual industries. Only industries located in designated Industrial Estate can discharge
their influent, after pretreatment, to the central wastewater treatment facility provided by theIndustrial Estate Authority of Thailand (IEAT). From monitoring program by PCD, sometreatment facilities are not functional and the discharges are not complied with the effluent
standards.
Voluntary Approach
The Cleaner Production (CP) is most popular of voluntary approach that initially starts as atool for industrial sector to prevent pollution from its sources. Currently, the concept has been
expanded into various sectors which include processes, products and services. CP is also the
backbone in “Sustainable Consumption and Production” which is the umbrella method
supporting sustainable development. The Thai Government has developed the National-115-

Cleaner production Plan for the year 2001-2009. The vision of the plan states that “Principleof cleaner production will be applied to all activities with efficiency for the achievement of
production, reduction and control of pollution, natural resources and environmental
management, quality of life with benefits from the country development”. Since then, CP has
been widely applied to reduce waste discharge from industries in pilot areas such as factory in
the Thachin and Songkla Lake basins. Ministry of industry has also promoted cleaner
production for small and medium enterprises (SMEs). The government is currently
developing the green procurement to support waste minimization.
Basin Management
The basin management approach can support the concept of protection of the water
environment by keeping pollutant loads to the environment within carrying capacity of thenatural purification process. This approach incorporates with water quality and quantity,
aquatic resources and land development. Human activities as well as natural events that occur
in a basin or watershed can effect water quality throughout the entire system. The basin
approach is a coordinated and integrated method to link science, waste discharges under
permit system, and other water pollution control and prevention activities to meet the goals or
water quality standards. The Pollution Control Department (PCD) has developed masterplans for water-quality management for all 25 river basins in Thailand. In the water quality
management plans, major river basins were undertaken which mainly include wastewater
management in the plans. Priority to construct wastewater treatment facilities inmunicipalities was principally recommended as well as the controlling of wastewater fromindustrial and agricultural sources. Water quality modeling and the geographic information
systems (GISs) have also been continually developed and used as the tools to help decisionmakers in water quality management processes.
Currently, local municipalities carry out the role of river and basin management. There is no
single administrative body that takes responsibility for planning and management of the basin
as a whole. Consequently, basin management and planning is typically uncoordinated andcarried out without due consideration for upstream and downstream effects. Up to now,
integrated water resources management such as basin management, has not yet been put into
practice in Thailand. PCD has been taken a leading role by firstly developing a water quality
improvement master plan at the Thachin River Basin as a whole basin in 1996 and theninitiating implementation of the action plan since 2000. Since then, there is not much progress
due to the lack of cooperation and budget availability especially for construction treatment
facility at the lower part of the basin. Currently, water quality of main stem of the Thachin
River is still severely polluted and the quality of water is less than the level of water quality
standard especially in the middle and lower parts of the river due to excessive organic loads.

-116-

Public Participation
Public participation in water quality management in Thailand is becoming more progressive
especially in the water quality monitoring activities. The volunteer or civil society groups
were formulated. The volunteer groups monitor the conditions of streams, river and lakes.
They want to help for protection of water resources for beneficial uses. Many projects aim at
raising awareness of basic water management issues, human and nature links and theimportance of water quality to aquatic life, plus integrating local environmental studies into
the school’s curriculum in line with national educational policy such as in the Songkarm
River in the northeastern and the Thachin River in the central parts of the country.
Development of water curriculum is also the challenges to encourage school to bring theirchildren to learn about the environment problems situation. When they knew the situation,
they will participate to solve the problems. In Thailand, public has been participated asvolunteers in various activities such as litter cleanup, water quality monitoring,macroinvertebrate sampling, tree planting, stream inventory, and educational exhibits. The
civil society or non government organizations (NGOs) have been established in some areas
for implementing some activities related to water issues.
Partnership Formulation
In 2002, the Director General of the PCD, and the four Governors from provinces in theThachin River Basin agreed to cooperate for restoration the basin by signing the Partnership
Agreement of the Thachin River Basin. It aims to cooperate of reducing waste loads fromvarious sources of pollution in their political boundaries, to monitor water quality, to establish
the center of Thachin database, to promote and support public participation, and to support for
implementing the Thacin Rehabilitation Plan. The meeting of the Partnership was set once a
year to evaluate and review of the implementation plan. However, the Partnership Agreement
was not maintained and the governors were transferred from the basin. Beside, partnership
between government agencies and private sector should also be established especially withmajor polluters in the basin while public can participate and monitor the progress of action
plan implementation (Wijarn, 2003b)

Conclusion
Currently, surface water quality in the most part of Thailand can be considered as fairconditions, while some rivers flowing through large communities are adversely. Water
quality problems are affected by domestic and industrial wastewater discharges, agricultural
point and non-point source discharges, deforestation, and development projects. In many
parts of the country, surface water quality is severely polluted which has affected aquatic
resources, water uses for various proposes as well as human health. Enforcement of relating
regulations has to be seriously practices. To management water quality in the wholewatershed, integrated approaches should be taken into account in future such as ecosystemapproach. Public participation should be also promoted.
-117-

Thai government has launched many projects to resolve these problems, few of theseattempted to take a basin-wide approach. Most actions to date have been local in nature, withthe result that water quality continues to deteriorate in the river. Currently, the most urgent
water quality problems relate to dissolved oxygen depletion or excessive organic loads andhigh loadings of ammonia and bacteria, primarily from agricultural and domestic sources. The
government has put in place policies, plans and water quality standards in an effort to combat
the problem and has embarked on an ambitious program for the management of waterpollution generated from various sources especially municipal sources. But a lack of an
integrated approach combined with laws that go no enforcement, weak capacity, insufficientinvestment, and poor operations and maintenance systems have exacerbated the problem.
Limited community participation and low involvement of the private sector has further
pushed the onus on the government.

Recommendations
To maintain and improve water quality in major rivers in Thailand, the following
recommendations should be considered:- Since many pollution problems occurred as a result of improper land use in the basin.
Regional water quality planning at basin level is required because it provide logical areas
for water quality management. Basin is natural system with readily identified boundary. The
basin approach for water quality management should be applied because it highlights theconnection between land, water, and people. Water quality is impacted by population
growth, industrial development, agricultural production, and urbanization and development.
This approach incorporates on both point and non-point sources of pollution control. Thus,
the implementation of basin-wide total pollutant loads controls should be considered.
- As agriculture is a dominant land use in most of river basin in the country and is thus an
important source of pollution to the basin wide. Intensive study of water quality
degradation due to non-point sources of pollution is needed to be investigated.
- Waste load allocation should be applied to management wastewater discharges from various
sources of pollution. This depends on the assimilative capacity of the receiving water bodyand guidelines to attaining receiving water quality standards.
- Economic instrument for water pollution control should be applied. These instruments canprovide incentive that will result in a changed behavior of water users and polluters such as
pricing, tax etc.
- A water quality model and a geographic information system (GIS) should be applied as atool for water quality management. These technologies can assist stakeholders in evaluating
the impact of various management scenarios base on priority or strategies and land usechanges on the basin.
- Government should promote public participation on water quality management. Partnershipprogram between government agencies and public or private sector should also be-118-

developed. This will help government agencies for implementing the water quality action
plan.
- To address water pollution, Thailand should develop an integrated approach for water
resources management. This will involve:- fostering local community participation in water resources management;- harmonizing functions and regulations by addressing overlaps in institutions and jurisdiction,- improving the efficiency of budget allocation and rationalize investments for the wastewater
and water resources management sectors; and- promoting opportunities for private sector participation and public awareness about the stateof water environment.

Lao PDR

Introduction
Lao PDR is in the midst of relatively rapid economic growth and natural resource
development. Hydropower, mining and forestry are major areas of activity, while tourism,
agriculture and fisheries are also developing and changing. Urban areas are also growing as
population shifts and commercial and industrial development takes place. As a result there
are increasing pressures on the environment and an increasing need to manage natural
resources in a sustainable manner.
The country is generally rich in water resources. Total available surface water resources(including the flow of the Mekong River and its tributaries) are 55,000 m3 on an annual per
capita basis, the highest in Asia. However, little of the national water supply has beendeveloped. Total storage capacity of large reservoirs is less than 3% of annual surface flow.
Up to the present time the focus of water quality work in Lao PDR has been on generalenvironmental monitoring, project-related environmental protection (EIAs, EMPs, etc) andpublic awareness and education. The current rapid development of water resources andimpacts on watersheds is now bringing about greater risks for water quality deterioration.
Recommendations have been made in various contexts for improved water quality monitoring,modeling and other technical strengthening. However, rather than addressing individual areasof weakness, there is a need for a more systematic approach.
The objectives of this discussion paper are to:give a brief description of general situation and the issues affecting water quality in
Lao PDR and particularly in the Nam Ngum River Basin;make recommendations regarding institutional arrangements on water quality
monitoring and management, and other water quality related activities for further
technical strengthening.

Water Quality Situation in Lao PDR
The Water Quality Laboratory of the Ministry of Agriculture and Forestry reports that overthe past 15 years of monitoring, water quality in Lao PDR has generally been good and is not
significantly affected by human activities. This is in agreement with a Mekong River
Diagnostic Study by MRC which indicated that “water throughout the Mekong River Basin is
generally of good quality, but there are localized exceptions.”-122-However, with the pressure of rapid demographic growth, economic development andurbanization, water quality is increasingly likely to deteriorate. The major issues which may
arise include:

The installation of hydropower schemes pose some important water quality problems
or risks. In most deep-water reservoirs in the tropics, in the first few years following
impoundment, oxygen depletion will take place in the lower part of the reservoir. Thissituation is mainly due to thermal stratification and the decomposition of submergedbiomass or organic matter (overhead vegetation and carbon contained in the soil).
Water quality in the downstream river is strongly affected by water quality variationsin the reservoir. If the turbined water comes from a single, low-level discharge fromthe reservoir, it will be low in dissolved oxygen (anoxic) and may be high in noxious
compounds (methane, mercury, etc).
Lao PDR is rich in mineral resources and is increasing its exploitation of theseresources. In a number of parts of the country exploration, planning and actual mining
are underway. Mining uses water in both the mining and ore processing stages,
although little information is currently available on the amount of water which isconsumed. Water use is not included in mining licenses. In some cases mines,
processing areas and mine tailings (waste) storage areas are close to rivers andreservoirs.
Population growth in cities, towns and villages leads to extensive municipal waste andorganic matter release to waterways. No urban centers have access to comprehensive
piped sewerage systems. Treatment and disposal of urban waste water is generally notsatisfactory; most households rely on soak pits for wastewater disposal. Urban drains
act as secondary sewers, carrying industrial discharges and septic tank seepage andoverflow in the rainy season. As a result, water in the drainage system is invariably
contaminated with faecal matter from latrines and coliform from septic tank effluent.
The growing number of industries has increased the incidence and risk of pollution.
The larger mills and industries of concern in Lao PDR are pulp and paper, timber,food processing, garment manufacturing and cement factories and gravel pits. Most ofthese have only limited wastewater treatment systems for reducing waste
concentrations and loads in the final effluent discharge to waterways.
Organic and nutrient pollution and sediment can be discharged from agricultural areas.
These contaminants tend to increase during the rainy season’s high runoff and riverflows. The use of agricultural chemicals in Lao PDR is still relatively low and is
expected to remain so during coming years, apart from areas of more intensive,commercial production, including animal production. Increased irrigation can lead toincreased nutrients, pesticides and sediment entering waterways through agriculturaldrainage. An increase in the extent of irrigation can also open new areas forwaterborne disease vectors (mosquitoes, snails).
In mountainous areas, forest cover has been reduced by slash-and-burn agriculture,
conversion of land to agriculture, road construction and logging. The main trend inslash-and-burn systems has been a rapid decline in the length of fallow periods due toan increased demand for land and resources. Rotational cycles have declined to as low
as 3 – 5 years. Such short rotations ultimately degrade the soil and increase the timethat steep slopes are exposed and susceptible to serious erosion, leading tosedimentation, changes in the downstream flow pattern and other impacts on thedownstream water ecosystem.

-123-If special precautions are not taken, pollution discharges and the resulting reduction ofambient water quality will increase in frequency and impact. Aquatic ecology will be
particularly affected.
Water Quality Management Capacity in Lao PDR
Institutional Arrangements
The water resources in Lao PDR have been developed and managed by a number of line
agencies. As part of this multi-sectoral system, some agencies carry out water quality
monitoring, laboratory services, management of EIAs and other functions. The main agencies
with responsibilities for water quality management together with the respective samplingstations and parameters monitored at their target sites are shown in Table 1 and table 2,
respectively.
Water quality issues may be very important at a local level and involving small streams andother water bodies. These local issues may have a large impact on the safe water supply forhuman consumption and other uses, fisheries and other aspects of the environment. The mosteffective way to identify and deal with these local water quality problems may be throughwatershed planning and management.
Water quality monitoring is an important part of environmental monitoring under the MRCS
Environmental Program. Water quality monitoring has been carried out for many years
throughout the Mekong River Basin. MRCS has supported the monitoring and laboratory
work of the Water Quality Lab (WQL) in the Department of Environment. Samples havebeen taken from a network of 19 monitoring stations throughout Laos and 18 parameters havebeen analysed.
Water quality data is forwarded on a monthly basis from WQL to MRC and forms part of the
MRC water quality data base for the Mekong basin.

Policy and Legislation
The major policy and legislation on water quality is the Law on Environmental Protection(LEP) (adopted 3 April 1999) and related legislation.
Water and Water Resources (adopted in 1996) determines principles, rules and measuresrelative to the administration, exploitation, use and development of water and water resources.
In water quality context, it states that the Government will set standards for waste water
discharge. It prohibits the discharge of waste and waste water which lowers the quality of the-126-receiving water source. The relevant Government agencies must set standards, must take into
account the classification of the receiving water source, that water resource development is inaccordance with approved plans, and that regulations are followed. This implies a complete
water quality monitoring, planning and inspection / enforcement process.
Ambient water-quality guidelines for surface water have been expressed in the Draft
Regulation for Adoption of Ambient Environmental Standards (1999) of the former Science
Technology and Environment Agency (STEA).
Drinking water quality guidelines have been developed by the Ministry of Health inconjunction with WHO / UNICEF. The Decision on the Management of Quality Standards
for Drinking Water and Household Water Supply (2005) defines standards for drinking andhousehold water supply, including bacteriological, physical-chemical (aesthetic), and healthsignificant chemical parameters.
At the Mekong River Basin level, the Chiang Rai Agreement on Mekong River cooperation(1995) elaborates the international agreement to make every effort to avoid, minimize andmitigate harmful effects that might occur to the environment, especially the water quantityand quality, the aquatic (eco-system) conditions, and ecological balance of the river system,from the development and use of the Mekong River Basin water resources or discharge of
wastes and return flows.
Water Quality Monitoring and Management in the Nam Ngum River Basin
General features
Nam Ngum River Basin is the forth largest sub-basin of the Mekong River within the territoryof the Lao PDR. The basin is one of the most important in Lao PDR in terms of population,
economic activity, water resources and water resource development.
The existing water quality monitoring sites in the Nam Ngum River Basin is shown in Figure
1 and the locations, parameters measured and length of record of the permanent monitoring
network is shown in Table 3. Of the existing water quality monitoring stations in the Nam
Ngum basin, four are on irrigation reservoirs off the main stream of the Nam Ngum and only
two are on the main river – one on the Nam Ngum itself, below the NN1 dam, and one at
Thalath (on the lower Nam Lik). One site (Tha Ngon) has been discontinued. The station at
Ban Hai is on the Mekong River and not within the Nam Ngum basin.

This sampling site was set up to monitor water quality used
for irrigation and agriculture, fishery and domestic use. Wateris always clear. Water in the reservoir is stored during wet
season and released during dry season to enable a secondary
crop. About 50% of the water flow through the canaldischarges into the Nam Ngum river some 10 km from thispoint. Agriculture is practiced and consists of paddy rice
field and grazing land. The major water quality development
issues upstream of this sampling station now, or in future arelikely to be tourism development, future resort facilities, fish
cage culture and livestock farming. Water from sewage andwastewater could also enter the water body if not properly
designed.

This station is identified as a local or secondary station.
During the dry season from mid December to April water isdischarged from the reservoir and flows through the canal.
During the wet season the water is stored for secondary crops
in dry season. In the immediate area of the sampling site,
there are paddy rice fields with livestock rearing. There are
tourist resorts but of relatively small size. Future
development of tourism, fish cage culture and livestock
farming are likely. Monitoring will be continued to ensure
water quality is maintained for domestic, irrigation,
agriculture, and fishery uses.

The main purpose of this station is to provide information on
the impacts of upstream development. There are villages onboth sides of the river. There are, floating restaurants, fish
cages, livestock husbandry, tourism, agriculture withpumping irrigation system. A village is producing 2,000Kg ofsalt per day about 10 km upstream of the station. Continued
observation is needed due to rapid upstream urbanization,hydropower development, tourism and agriculture expansion.
Problems related to microbiological hazards or eutrophication
may arise in the future and contamination to the Mekong
mainstream is possible. A new water supply treatment plantof 40,000m3 per day for Vientiane city is planned near thisstation.

Water Quality Conditions in the Nam Ngum River Basin
The Water Quality Laboratory report indicates that over the past 15 years of monitoring,water quality in Lao PDR is still good and is not significantly affected by human activities.
There has been no significant change in water quality for all stations recorded.
Total suspended solids are variable during the year and generally loads increase during thehigh water season. Likewise, the high organic and high nutrients parts follows a seasonalpattern. Erosion and sediment transport are increasing at some sampling sites. The use ofchemicals is still modest and will be so in the short term due to lack of money for investment
and hence low demand.
The effect of urban and industrial activities in Lao PDR affects small local areas, and is not an
immediate threat to water quality mainly due to the relatively large flows of the MekongRiver and its tributaries, even during the dry season.
Water quality monitoring near mining sites is absent and is needed as more mines quarries arebeing established. Those new water quality monitoring sites will allow collection andmonitoring on water quality parameters that might be harmful and hazardous from the waste
water discharge and disposal of dangerous chemical agents. There has been at least one serous
release of hazardous chemicals into Lao rivers in recent years.
Water quality management in Lao PDR is at an early stage of development in regard to theinstitutional frame work, standards and experiences. The main constraints are poor facilities
and lack of financial support, limited human resources, need of efficient management
including data evaluation and calibration to assure reliability of reports.
Recommendations
The Water Resources and Environment Administration (WREA) needs to play an active andleading role in water quality management in line with its mandate on water resources andenvironment. Up to the present time the Department of Environment (DoE) and theEnvironment Research Institute (ERI) have made progress on general environmental
assessment, environmental regulation (through the EIA / EMP process) and public awareness.
Provincial offices have been established and some capacity building has been carried out.
The formation of WREA now means that the roles of DoE and ERI as well as DWR andDMH need to be clarified. Water quality monitoring, lab analysis and information need to bestrengthened. Stronger water quality policies and strategies are needed to deal with the rapid
development of water resources and possible impacts on water quality and ecosystems. The
updating of the National Water Resources Policy and Strategy and the possible review of the
Law on Water and Water Resources will provide the opportunity for this policy and strategy
development.

-130-

A “Water Quality Task Force” should be set up with representatives of each of the WREA
departments / institutes and other water quality related agencies. The Task Force should
prepare an action plan which should include subjects such as:Carrying out an assessment of water quality labs and making recommendations on
coordination and upgrading;

Setting up new water quality monitoring sites where needed, ensuring that data isforwarded from other government agencies and from private projects;

Development of a national water quality information system;Inclusion of water quality in the National Water Resources Policy and Strategy and theLao IWRM Support Program;

Inclusion of water quality in watershed planning;

Carrying out a training needs assessment and preparing a training plan, including all of
the main water quality agencies. Also providing a water quality awareness courses.

Abstract
Bang-Pa canal located in Ratchaburi province is a natural waterway passing through different
communities with its various usages. An alteration in canal’s geography due to thedevelopment of industrial estate coupled with the pollutant discharges by upstream
community has hindered the use of canal water for the downstream community who depends
on the canal most. This research project is carried out to mobilize stakeholder’s participation
on environmental issues of Bang Pa canal. It involves capacity building of the community inwater quality conservation through water quality monitoring and biological assessment using
macroinvertebrates. For this, 60 volunteers from four sub-districts were actively involved.
The integrated results of water quality and macroinvertebrates analysis show that the
upstream water quality of the Bang-Pa canal is better as depicted by physico-chemical andbiological parameters (water quality index). As the canal passes through the community, thequality deteriorates as the polluted water flows into the canal through alternative paths. The
activities of the project have been integrated with the ongoing environmental efforts of thevillagers on the conservation of the canal to maximize the effect. The involvement of local
administration was rated as satisfactory by the community towards the issues of the canal.
However, participation especially from the women residents is further required forconservation of water quality.
Keywords: Water quality, biomonitoring, macroinvertebrates, community participation,
capacity building.
Introduction
Bang-Pa canal is a natural waterway located in Ratchaburi province, a fast growing peri-urban
community 80 kilometers southwest of Bangkok. The canal has a total length of 37 kilometers
spanning from Potharam District to Muang District of Ratchaburi Province. The canal passes
through six sub-districts, namely, Klongkoi, Chedsamean, Don Sai, Sam Ruan, Pikulthong,and Bang-Pa. The uses of Bang-Pa canal varies as it passes through one community to another.
During the past decade, the geography of the canal is altered due to the construction of
Ratchaburi Industrial Estate located in Chedsamean sub-district where parts of canal werefilled up in order to create land area set aside for future development. Nowadays, the canalblockage has hindered the usages of canal water in the surrounding areas where the waterway
is prone to discharge from industries and also as a channel to receive wastewater discharged
from household and livestock farms on daily basis by the villagers (Ongsakul, R. andThongbhakdi, A., 2006).
The eminent pollution problem not only create burden and loss for those who rely on the usesof canal water but also creates conflict on transboundary social issues among thestakeholders; especially in the downstream area of Sam Ruan Sub-district since people here-132-

depend on water from the canal for their daily activities. Many villagers are engaged in theornamental fish business (for export), fruit, vegetable and rice farming. An initial effort wasmade with the collaboration of PDA (Population and Development Association) through theestablishment of conservation clubs as community based organizations (CBOs) for“Conservation of Bang Pa Canal” which is funded by Ratchaburi Power Plant. Their activities
are confined to plantation of trees, establishment of small parks along the banks, growing
grass as natural water treatment system, and collecting garbage and weeds. However, theconservation groups organized in each village do not have good coordination of theiractivities among each other. As a result, the core problems remain in place and the pollutions
in Bang Pa Canal continue to persist.
The project is carried out in the lower part of Bang Pa canal covering 4 sub-districts namely:
Don Sai, Sam Ruan, Pikulthong and Bang Pa, with the collaboration of PDA focusing on thedevelopment and capacity building of community for water quality monitoring system using
biosensors for water quality conservation. Sam Ruan sub-district was the main focus area ofthe project and the other 3 sub-districts were considered as the dissemination area.
Methodology
Preliminary survey was performed through questionnaire distributed to the members of local
conservation clubs and local people randomly in order to identify the linkages between
community and their activities with respect to the existing canal condition. Questions werealso asked to verify the level of satisfaction of the community towards the various aspects oflocal governmental actions on canal conservation. Opinions were distinguished based on
gender equality.
The project had identified volunteers through series of meetings based on the existing
conservation clubs, active groups such as: women groups, local school and local
governmental agencies for the mobilization of local community within their own villages.
During the meetings, activities to be conducted were presented for prioritization by theparticipants. Prioritized activities maximized the level of public participation in the projectthrough their own decision making according to Appreciation Influence Control Process(AIC) which helped in better implementation the of project activities. However, for eachgroup of volunteers, different activities were developed in order to integrate the activities into
their own agenda or annual plan based on “Conservation of Bang Pa Canal” funded by
Ratchaburi power plant. These volunteers participated in water quality assessment,
monitoring, and determination techniques.
A total of 11 sampling points (identified as RA1-RA10) had been determined and all recordedwith GPS coordinates which includes; 1 reference sampling point (man-made irrigation canal)and 10 sampling points located along the canal and waterways which passes through the 4
sub-districts. A detail sketch of the canal and waterways including 10 sampling points isgiven in figure 1.
Field analysis of physico-chemical parameters for water quality was conducted with the active
participation of volunteers. Parameters that were measured include pH, Dissolved Oxygen(DO), Conductivity, Total Dissolved Solids (TDS) and Temperature using onsite using
portable field instruments. Phosphate analysis was done in the laboratory. Apart from water
quality analysis using physico-chemical parameters, biological samplings for-133-macroinvertebrates were carried out in Sam Ruan sub-district to develop a biologicalcommunity based water quality monitoring system.

Figure 1. Schematic sketch of Bang Pa canal and the location of 10 water sampling points.
This was carried out along the water sample collection with the collaboration of PDA, local
volunteers and project team. Samples of macroinvertebrates collected were identified on-siteusing a reference guide (Tilling and Kanjanavanit, 2000). Unidentified samples were
preserved in 90% ethyl alcohol and taken back to be identified at the laboratory. Water
Quality index was developed based on giving pollution score to the macroinvertebrates andassessment of water quality was done by using the water quality index (Tilling andKanjanavanit, 2000).
Training on water quality monitoring for the local community was conducted by thedevelopment of a learning center at the local school for their technical capacity building. The
center was developed as a base for information system and laboratory for water quality
analysis. The center provides learning resources based on the skilled level of the community
regarding water quality monitoring and the management of environmental issues raised by thecommunity members. Volunteers were trained at first at their respective conservation clubs
during water and macro invertebrates sampling. The formal training was performed at thelearning center for the school children, volunteers of each village PDA officers and thecommunity with the presentation of results of water quality monitoring.
Results and discussion
Bang Pa canal plays an important role in livelihoods of people living along the entire path ofthe canal, especially in Sam Ruan sub-district. Due to its flat topography, the area is suitable
for agriculture. Villagers are involved in ornamental fish farming (Moo 3), vegetable and rice
farming and cattle farming. The canal is therefore used as an input of water for fish pond,
vegetable gardens and paddy fields.

-134-

It was found from preliminary survey that there is still high level of dependency on the use of
canal water (73%). Among them 74% are male and 26% are female. Canal water is utilized
primarily for domestic use (cooking, laundry, dishwashing) and also for bathing and otheruses such as plant watering, car washing. Only 47% of the respondents who use canal water
do pre-treatment before using. Around 44% of the whole population is involved in canalconservation activities (32% male, 12% female) such as removal of aquatic weed, clean up
along the canal, providing environmental knowledge to the community and improving
environmental surroundings along the canal. The villagers opinion towards the local
governmental agency Tambon Administration Organization (TAO) about the pollution issue
was some how satisfactory in terms of priority but the satisfaction level decreases when
considered the policy and promotion done by TAO.
Water quality assessment through physico-chemical and biological analysis
A total of 60 volunteers were identified by the project team from 4 sub-districts during themeetings for the community based water quality monitoring. They are the members of theconservation clubs, heads of villagers, local public health officers, members of women groups,
ornamental fish farm owners, senior elders, members of local government agency (TAO),
public health officers, local school teachers and students.
Bang-Pa Canal is classified as “Surface Water Type 2” under PCD’s (Pollution Control
Department) Surface Water Quality Standard. Water depth in the canal is generally more than
two meters with some exceptions where the canal passes through the main communities,
water depth is decreased due to large amount of sediments. The canal channel is wide (> 6
meters) with the shape of stream bank steeply sloped. The bottom of the stream is muddy.
There are several species of aquatic plants covering the surface of the canal. The dominant
species is water hyacinth which hinders the flow of water in the canal. Stream sides are being
used as grazing area for cattle. The sites are also used as place of waste dumping and openburning near the houses. Water flow is interrupted at the upstream of Sam Ruan sub-district
by the development of a blockage between Don Sai and Sam Ruan sub-districts in order toprevent the flow of polluted water from upstream communities into Sam Ruan sub-district.
The dissolved oxygen concentrations of Bang Pa canal varied from 1.53-4.04 mg/l. The
lowest value (RA1:1.53 mg/l) was measured at the blockage point of Don Sai (Don Sai side)
sub-district where water is totally stagnant. Dissolve oxygen values were higher at the
upstream of the canal (RA2:4.04 mg/l, RA3:3.96mg/l) in Sam Ruan sub-district where
upstream polluted water could not pass through from Don Sai to Sam Ruan (Figure1).
Additionally they are located near irrigation canal which receives clean water from Tha Rab
sub-district. But as it passes through the community of Sam Ruan, water quality deteriorates(lowest RA5: 1.81 mg/l, near Nong Tha Pae swamp) as the water from upstream flows into
the canal through alternative paths (Nong Tho Pae swamp) along with the pollution from
community.
Conductivity was measured together with the determination of Total Dissolve Solid (TDS) in
water. In general, conductivity values measured (ranging from 337 to 1042 µs/cm) werehigher than the established standard of type 2 (< 500 µs/cm). The highest value was obtainedat the point of lowest DO (RA5). Higher values were obtained from two sampling points:
RA1 (994µs/cm) and RA2 (999 µs/cm) which are situated at the opposite site of the blockage
point.

The nutrient loading in terms of phosphate concentration varied from 0.1566 to 0.5058 mg/l
within Sam Ruan sub-district. The upstream of Moo 4 had the lowest value. The results ofmacroinvertebrates sampling were translated into Water Quality Index (WQI) and assessmentof water quality was done based on that index. Table 1 and 2 shows WQI developed based on
the number of total macroinvertebrates found during the survey conducted by the project teamwith the identified volunteers and the assessment of water quality based on that. The
assessment shows that the water quality varies from average to rather clean water. When the
results of physico-chemical analysis were integrated with the results of macro invertebrates, it
showed that the quality of upstream water in Sam Ruan sub-district of Bang Pa canal is better.
This is mainly due to the location of the blockage point and the irrigation canal. Although
polluted water cannot pass through the blockage but the people still experiences the pollution
at the downstream through alternative paths.

The training (figure 2) was conducted covering all the basics technical knowledge of water
quality monitoring through classroom activities for volunteers from conservation club as wellvillages, PDA officers and school children. The technical capacity of the individual was build-136-

during the training by lending the equipment and analyzing the samples for water quality andmacroinvertebrates by themselves. Apart from the classroom lessons, field survey wereconducted around the community and environmental management sites, which made themable to identify the sources of pollution and best sustainable solution for the management of
the canal. These were also discussed during the training. The training allowed the project tofind the strength and weakness of each community so that, the strength of one community
become a valuable knowledge to be transferred and shared with other communities andenhance inter-community participation.

Conclusions and recommendations
The obtained results imply that water condition in Bang Pa canal has been deteriorated
dramatically at some points within Sam Ruan sub-districts ( DO value 1.81 mg/l) fromanthropogenic point sources and non-point sources (agricultural runoff) due to the daily
activities of the villagers. The better quality of upstream water is due to the human madeinterruption of water flow. Conversely, the results from questionnaires show that there is stillhigh dependency on the use of canal water. An effort was made by the project to implement a
low cost simplified method of biomonitoring technique and to maximize the public
participation on canal conservation activities through training.
Since its initiation, the project has brought together many different stakeholders from various
sectors including local communities, governmental agencies and community basedorganizations in pollution prevention and canal conservation.
The increase in interest in water quality domain can be made through stakeholders/local
community participation. It is necessary to increase local community involvement including
both genders in water projects as this participation helps to ensure public perception in termsof environmental awareness, trust and ownership towards the initiation of community driven
water quality monitoring program.

Abstract
Access to sufficient amounts of clean water is both a fundamental human need and right. Yet,
more than 1 billion people worldwide can not access clean water and 2.6 billion people live
without adequate water sanitation (UNDP 2006). Improving the access of poor people towater has the potential to make a major contribution towards poverty eradication. In Lao PDR
where 78% of the population is rural, many inhabitants are likely to be exposed to water
quality-related hazards due to lack of access to potable water and/or water sanitation. In thiscontext, this study focuses on stream water quality along a Mekong tributary that flows within
a mountainous, composite land-use catchment of northern Lao PDR. Water quality was foundto vary greatly depending on (i) the location along the stream (ii) the prevailing rainfall
conditions and (iii) stream flow conditions. Overall, water quality reflected the balance
between the stream self-cleaning potential and human pressure on the riparian zone. Besides
these human induced pollutions we also noted spontaneous enrichments in metals in swampy
areas fed by dysoxic groundwater. Based on our survey, we propose recommendations toimprove or maintain stream water quality and for environmentally friendly management of
surface water resources in the uplands of northern Lao PDR.

IntroductionMore than 60% of developing countries' rural populations (i.e. more than 2 billion people asper 2004) lack access to sufficient amounts of clean water (WHO-UNICEF 2006) and are at
risk of exposure to water quality-related hazards such as infectious diseases and intoxicationby chemicals and/or radio-elements. In Lao PDR, 78% of the population is rural, living
standards are very low overall and numerous communities still lack adequate water supply
and sanitation infrastructures. A decade ago, the United Nations (UN 1998) concluded
optimistically on stream water quality in Lao PDR. This conclusion was partly based on alimited dataset (34 measurements made in the country's main rivers), and on the fact that thecountry's population density is low. While the population density remains low today (24people per km2; NSC 2005), we undertook this survey to test whether water quality
assessment based on main rivers only properly reflects water quality as experienced at thecommunity level. The Mekong basin includes hundreds of waterways upon which many ruralcommunities rely to fulfil their daily needs. Most such waterways get very turbid during
periods of storm flow (Maniphousay and Souvanthong 2004), which greatly increases theoccurrence of infectious diseases and intoxication, via particle-bound transport (Lamaningao-138-

and Sugiura 2004). Our survey was conducted in a typical composite land-use catchment ofnorthern Lao PDR, near the city of Luang Phrabang, along a perennial third order stream
passing through villages close to the Mekong corridor but having no direct access to the main
waterway. While, we did not intend to identify and analyse all factors and processes
contributing to surface water quality, we tried to identify the main causes contributing to thespatial variability of some water quality indicators in the context of northern Lao PDR.
Among the underlying factors studied, we paid attention to (i) land use along the riparianarea; (ii) wastewater discharge along the stream and (iii) suspended sediment loads during
floods.
Materials and methods
The Houay Xon catchment
The study was conducted along the Houay Xon stream, part of the Mekong basin in northern
Laos (Luang Prabang Province). This stream drains a catchment of about 22.4 km2 and flows
into the Nam Dong River before its confluence with the Mekong (Figure 1). The 10.6 km long
perennial stream flows down along a mountainous environment representative of the sloping
lands of the Mekong valley. Within the catchment, altitudes range from 280 to 1336 m, with amean slope gradient of about 31%. Composite land uses typical of northern Lao PDR occur
within the catchment. The Houay Xon flows through five villages, successively. The overall
land use units (Figure 1) roughly match the catchment's main morpho-hydrological units: (1)the south-eastern Phu Phung massif predominantly covered by old secondary forest; (2) the
upland areas of the north-eastern and south-western parts, under shifting cultivation with short
fallow; (3) the residential areas surrounded by teak plantations found along the main stream;and (4) the irrigated gardens in the peri-urban area of Luang Prabang, located on an alluvial
terrace of the Mekong. The mean annual rainfall recorded at Luang Prabang from 1960 to2006 is 1263 mm, about 77% of which falls from mid-May to mid-October, with high interannual variability (SD 345 mm, coefficient of variation 27%, min. 444 mm, max. 2100 mm).
In 2007, the year this study was completed, the annual rainfall was 1139 mm.
Field survey
To relate water quality data to the catchment's spatial features (land use, human activities,
etc...), we made spatially distributed measurements. Temperature (T), pH, electricalconductivity at 25ºC (EC), redox potential (Eh), and dissolved oxygen content (DO) were
measured using a YSI MPS (Multi Probe System/Data Logger) meter. All sensors werechecked daily before starting measurements. DO data were transformed to oxygen saturation(DO-sat) in %, using the formula of Hua (1990). To analyse the effects of land use on water
quality at baseflow, 109 point-observations were made along the Houay Xon (83, 100-m apartstations) and its main tributaries (26 stations), at the end of the dry season (31 May 2007)
until the confluence with the Nam Dong River. To examine the impact of floods, regardless ofdomestic wastewater discharge, 11 observation stations were established 20 metres apart,within the Houay Pano catchment (upstream Houay Xon). These stations were sampled once
during a low flow period prior to the rainy season (28 May 2007) and then again during thefirst storm flow of the rainy season (4 Jun 2007) (Table 1). The sampling point locations wereapproximated using a portable GPS (GARMIN XL12) and an altimeter (SUUNTO
Instrument). Stream discharge at the different sampling points was estimated by chemical
tracing (Silvera et al 2007).

Water sample collection and laboratory analysis
Seventy water samples were collected to determine the suspended solid load (SL) and totalcolony count at 37ºC (CC37). Samples were collected on the day or the day after each of thephysico-chemical surveys described above. Samples were collected by immersing bottles,
neck pointing upstream, so that there was no contamination by bed sediments. SL, expressedin mg l-1, was estimated as the weight of solid retained on a pre-weighed 0.45µm membrane
after filtering a known volume of sample (about 1 litre). Sampling was always carried out at
the same time of the day, i.e. mid morning to early afternoon. Water samples for total flora
determinations were stored in a cool, dark ice box and delivered to the Nam Papa Laolaboratory in Vientiane within 12 hrs. CC37 was estimated following the standard pour plate
method. The results are expressed as colony forming units (CFU) per ml.

Results and discussion
Potential hazards due to naturally contaminated groundwater
In the upper part of the catchment (Houay Pano stream, land under shifting cultivation),orange-coloured iron oxide flocculated at several points within the stream channel. These
metal-rich colloidal features occurred at a location where reducing conditions prevail: DO-satof 12 % (triangle 1, Figure 2), pH=6.9 and Eh=88 mV. The Eh-pH measured at this station iscompatible with the presence of soluble ferrous iron hydroxides (FeOH+) in stream water,corresponding to local ex-filtration of subsurface water (Ribolzi et al 2005). Soluble ironcompounds are common in soil solutions with high levels of organic matter (1-6 % in Houay
Pano soils). When dissolved organic matter enters groundwater, the water may become
anaerobic and iron becomes soluble. During the ex-filtration process, aeration of the Fe2+
charged groundwater leads to the precipitation of amorphous oxides, due to the rapidoxidation of Fe2+ at near neutral pH (Stumm and Morgan 1981). This in turn alters the pH in
the vicinity of groundwater inflow sites. Oxidizing bacteria may accelerate this flocculation-140-

process. The presence of dissolved iron or colloidal features in streamwater should not be
considered hazardous in itself; yet, it indicates local physico-chemical conditions under which
toxic metals can be mobilized (e.g. Cu, Cd, Zn, As). Farmers commonly use suchgroundwater sources for various purposes: fish ponds; drinking water; small irrigation;watercress beds. Such practices may not be innocuous as streambed sediments, stream waterand aquatic vegetation exposed to subsurface inflows can accumulate metals. To avoid thisrisk, such seepage waters should only be used after aeration and deposition of their metallicions (e.g. into streambed sediment).

Impact of land use and human activities along the riparian area on water contamination
Livestock roaming
In the upper catchment under shifting cultivation, livestock was seen roaming close to and in
the stream causing sediment particles to be mobilised and SL values to reach up to 2 g.l-1(Figure 2, triangle 2). This increased turbidity was associated with local microbiologicalpollution (CC37>2000 CFU ml-1). This is consistent with previously reported correlation
between faecal bacteria (Escherichia coli) load and turbidity at near-base-flow in a mixed-use
watershed (Randall et al 2006). Stream water contamination by faecal coliform through soilleaching also seems higher in areas partly or fully covered with pastures than in forested andcultivated areas (George et al 2004). In the Houay Xon, bacterial contamination was very
local, most probably due to dung piles rolling down from a livestock shelter into the stream. It
is noteworthy that, due to the filtering effect of aquatic plants, acceptable levels of suspended-141-solid content and sessile (attached) bacteria were recovered a short distance (~100 m)
downstream from the contamination point.
Use of fertilizers
In addition to increased sediment load in the river (Valentin et al., 2008), water quality in the
Houay Xon is affected by a variety of pollution sources. Upstream Herbicide use amongst
upstream farmers has recently become more common. The chemicals used are principally
Paraquat Dichloride and glyphosate-isopropylamonium. Paraquat is classed as toxic forhumans and presents a serious risk to aquatic environments.Glyphosate-isopropylamonium isless toxic for humans and the environment but there is still the potential for the water table tobecome contaminated (PAN, 2007). While fertilizers are not used in the Houay Panocatchment, their use is widespread the market gardens where at least two types of fertilizers
are used. Downstream, rice growers frequently use chemical and organic fertilizers. The
most common chemical inputs are urea (N46 P0 K0 and N16 P20 K0). Manure is extensively
used because it is 5 times cheaper than chemical fertilizers. Fertilizers often end up in thestream, either during application in plots adjacent to the stream or through runoff, soil erosion
and the occurrence of landslides.
Fish breeding activities
Fishponds found in Ban Lak Sip and Ban Donkang are filled by diverting the stream or byplacing a pond directly in the course of the stream, which means that wastewater flows
directly into the Houay Xon. None of the fish farmers own equipment or have set up a systemfor collecting or treating the wastewater. The waste consists primarily of fish food andexcrements. Whilst the food is mostly organic, fish excrement, affects the microbiologicalquality of the stream by encouraging the growth of coliform bacteria. Thus this economic
activity poses a serious risk to the health of the surrounding villagers. Measurements of the E.
coli concentration, an indicator of health risk, show that after Ban Lak Sip the stream is
unsuitable for swimming/washing, with a level of 230 MPN/100mL, more than double thesafe standard. It is difficult to calculate the volume of wastewater released by the ponds,
especially since 80% of the informants leave the ponds open to the stream permanently.
Given that the system for managing the water level in the ponds is approximately the same inthe studied area, we can calculate an average outflow of > 80 m3 per week per fish farm. The
pollution caused by the fish farms is thus of a relatively small scale in terms of toxicity but theamount of waste is large.

Domestic wastewater and household refuse
The physico-chemical characteristics of the stream water changed dramatically when it passed
through the first upland village (Ban Lak Sip): DO-sat decreased from 88 to 5%, CC37

-143-

doubled, EC increased from 298 to more than 400 µS.cm-1 (Figure 2, triangle 3), temperature
increased from 26.0 to 30.2 µC, pH decreased from 8.2 to 7.2 and Eh decreased from 220 toless than 120 mV. These changes were clearly related to (I) domestic wastewater discharge,(ii) human and animal excrements and (iii) household refuse accumulation in the stream bed.
These factors, in association with low stream discharge conditions, led to organic matter
enrichment of the stream and a decrease in the stream velocity, which in turn induced anoxic
conditions (Figure 2). After a distance of about 1km downstream from Ban Lak Sip, natural
filtration and other processes led to the recovery of stream quality back to its initialcharacteristics (Figure 2). Then, in and up to 900 m downstream from ban DonKang, DO-sat
remained high (i.e. between approximately 80 and 110%) in spite of numerous waste water
discharge points and domestic activities. This rather steady oxygenation rate is due to thestream being fed by oxygenated tributaries (dilution effect) and, above all, a turbulent flow
regime that maintains aerobic conditions. Further downstream, the DO-sat suddenly decreased
down to 32% because of organic-rich waste water discharge from an alcohol distillery (Figure
2, triangle 5). Once again, it took approximately 1 km for the DO-sat to return to its originallevel. Contrary to DO-sat, CC37 increased considerably from Ban Donkan onwards (Figure 2,
triangle 4), and remained high until the confluence with the Nam Dong. Tributary inflows did
not lower the CC37.
Impact of floods on water contamination
The stormflow measurements described below were conducted within the Houay Panocatchment during the first main runoff event of the 2007 rainy season. This event occurred ashort time after the farmers of Ban Lak Sip had slashed and burned approximately 42% of thecatchment area for annual cropping. Almost all the riparian zone and large hillslope areas
were therefore bare; the soil surface and stream banks were unprotected, hence exposed toerosion. This flood was the result of a sudden intense downpour of 54 mm (maximal rainfall
intensity of 110 mm.h-1 calculated over 6 min time steps) that produced considerable amountsof suspended sediments at the main outlet of the Houay Pano catchment (1.7 Mg ha-1, i.e.
~23 % of the annual suspended yield). Table 1 presents a comparison between base and storm
flow observations. No significant differences between base and storm flow were found for
DO-sat (P value > 0.025). In contrast, stream flow dilution by rainwater lowered T, EC and
pH during storm flow, while Eh increased significantly. Unsurprisingly, SL was much higher
under storm flow conditions, corresponding to i) soil erosion in inter-rill areas (Chaplot et al2007), rills and gullies (Chaplot et al 2005) and ii) the washing-out of free aggregates andsome of the fragmented organic matter accumulated at the soil surface throughout the dry
season. All the samples collected during the flood and one collected at base flow had SL >1
g/l, values which may greatly affect water usage and aquatic life, from phytoplankton to fish,by limiting light penetration. SL, especially when particles are small (less than 63µm), carry
many substances that are harmful or toxic. In rivers, these fine particles are a food source forfilter feeders which are at the base of the food chain, leading to biomagnification of chemical
pollutants in fish and, ultimately, in humans. High SL also limits reservoir life throughsedimentation of suspended matter. Microbiological studies of waterways are usually not
carried out during rainfall-runoff events. Even though, during and after such events, there areoften significant increases in turbidity and suspended solid loads, which are frequently
interpreted as an indication of bacteriological contamination. Table 1 also shows that CC37
soared under storm flow conditions. These observations are consistent with those of George etal (2004) who reported that, in small streams, fecal coliform bacteria were linked to particles
and that their abundance was proportional to the suspended sediment content.

Conclusions and recommendations
The expansion of Luang Prabang and its population growth pose a major challenge to city
planners. In the near future, it will lead to an increased demand for sanitation infrastructuresand freshwater resources, notably for irrigated peri-urban market gardens. The current
expansion follows a centrifugal dynamic that radiates from the historic peninsular city andproceeds uphill along the course of waterways. The following recommendations are suggested
in order to reduce or mitigate potential negative impacts of this urbanisation process on water
quality:•••

Riparian zones along streams and rivers should be managed in an environmentallyfriendly and sustainable manner.
Extraction of stream water for industrial and irrigation purposes should be managed
according to estimates that take into account rainfall variability and upstream land use.
Over-extraction of stream water will place freshwater resources under stress.
Authorities should encourage the development of community-based water sanitation
systems as unprocessed domestic wastewater discharge is currently rising.

To support the above mentioned recommendations, we suggest that an agreement between thecity of Luang Prabang and the surrounding villages be implemented. This agreement may
follow the Payment for Environmental Services (PES) concept: rural dwellers could loosen
the pressure on riparian areas in return for which the urban citizens could finance sanitation
infrastructures upstream via, for example, the taxation of profits made on certain tourist
activities in Luang Prabang. Finally, our study raises the issue of the spatial scale relevance offield observations regarding the question that needs to be answered, i.e. do upland people ofnorthern Lao PDR have access to good quality surface water? Strategies that consist inmonitoring large rivers generally provide a smooth integrated fingerprint of entire watersheds(e.g. UN 1998). This is unquestionably useful for global water resource management at theregional scale. However this approach may mask system internal variability and hence part ofthe local community level reality. Conclusions from such large scale studies should therefore
be considered with the greatest care.

Abstract
The Kingdom of Cambodia has tremendous water resources and natural assets, which kept as
major tools to the national development. Besides these resources, agricultural sector isrecognized to importantly support the socio-economic development, meanwhile more than
85% of people are farmers. Industrial, tourist, transportation, etc., are also crucial sectors forthe national development. Significantly, these kinds of development require necessarily toabide by the environmental legal instruments to ensure the environmental sustainability. Itmeans that the maintenance and protection of water environment should be considered andimplemented in parallel with development concept. Vice versa, the water environment mightby deteriorated or polluted by unsound environmentally development, that means to destroy
ourselves, our benefits, including our next generations.
The water pollution concerns were identified, and there are still gaps in: (i) our understandingof the integration of water environment management into sectoral development; (ii) our
ability to recovery of degraded water environment and water quality decline we have done toit; and (iii) our knowledge of the cost of failing to take appropriate action to abate its
degradation.
Up to now, it is still less possible to assess the state of water environment and water pollution
at both national/ provincial levels, including its management, and the Royal Government of
Cambodia, is now taking much attention to deal with the water environment management andprotection we already know exist. Series of related legal instruments, strategic development
plan and policies, and their applications ─ all are evident implicating to above captioned
targets.
Carrying out these legal instruments, under the collaboration with key stakeholders, the MoE
is taking action to regularly monitor and control various activities which harm to water
environment and human health. During the implementing, the MoE still confronts with many
constraints that require improvement. Capacity building, institutional strengthening,technological transfer, key stakeholder participation as well as the cooperation among
concerned ministries/ institutions, international organizations and NGOs, and with othercountries in the region, all these are key elements aiming at minimizing and phasing out theabove constraints.
BackgroundCambodia lies in Southeast Asia in the southwestern part of Indo-Chinese peninsula. It is
located between latitudes 10° and 15° North and longitudes 102° and 108° East in the-147-Tropical North, and covers an area of 181,035 Km2. Cambodia shares its 2,438 km borderwith Thailand, Laos PDR, and Vietnam. The country maximum extent is about 580 km fromeast to west and 450 km from north to south. The total boundary of the country is 2,600 km ofwhich approximately 5/6 is land and 1/6 is coast.
The country receives abundant water quantities from the Mekong River, Tonle Sap River,Bassac River, Tonle Sap Great Lake, their tributaries in between rainy season, but more partsof the country are confronted to water shortage for household uses and irrigation during thedry season, due to an insufficiency of water storage, canal and irrigated systems, meanwhile
farmers are accounted for 80%. Water resource is determined as an invaluable natural asset
for Cambodians with multi-functions for the development of various sectors such as:
agriculture, fisheries, industry, tourism, navigation, hydropower, transport, etc., which is the
crucial resource for poverty alleviation. Of course, with these tremendous water resources andrichness inundated habitats, Cambodia becomes the home of endangered and rare wildlife
species, especially waterfowls and fish species in Tonle Sap Great Lake (waterfowl camp),
freshwater dolphin in Mekong River (Stung Treng and Kratie Provinces).
Up to now, the exploitation and aquatic resources based development, commonly recognized
to be caused severe concerns to the environment and loss of biological diversities, including
water pollution, unless the environmentally sound management and practice was applied.
Therefore, the implementation of environmental norms/standards is absolutely required by theenvironmental law and related statutes in order to ensuring sustainable and/or richness
conditions of water and its natural resources, as well as the promotion of public and/or
community participations. It means the conservation and protection of water environment andits related resources should be considered and implemented in parallel with the development
concept.
Pollution aspects to water environment
In a brief, some kinds of development activities in Cambodia are being caused pressures towater environment and human health of which the Ministry of Environment (MoE) and line
institutions are paying attention in parallel the taking action to intercept and minimize throughthe application of real countermeasures 1 and public awareness raising. The occurrence ofnegative effects resulted from many types of activities as follows:a) Both treated and untreated effluents from industrial sector are being discharged into
receiving waters;b) Agricultural development by using agro-chemical which is more popularly consumed inpaddy fields, specially in gardens along and/or closed to watercourses;c) Rapid growth of urbanization which is beyond the land use planning, and without acentral wastewater treatment, therefore, domestic wastewater are directly discharged into
sewage system, and finally run off to retention pound to take the treatment process by
natural conditions;d) Activities of gold mining and other mining are closed to water sources;1

Based on the environmental legal tools-148-e) Solid and liquid wastes discharge from slaughterhouses, poultry, piggery farms, and thelike;f) High sedimentation load resulted from soil erosion at upstream and local watersheds 2 ,including river bank collapse;g) Fuel-oil transportation by waterway without adequate safety facilities and emergency
planning. Floating oil stations/selling are found to locate in dense-floating communities
along main watercourse, e.g. Bassac river, and Tonle Sap Lake; andh) Transboundary water pollution resulted from various development activities at upstream
riparian countries.
Environmental Legal Tools and Their Application
The series of environmental legal instruments including relevant statutes have been enteredinto forces which aim to protect and conserve water environment and its related resources.
These include such as: (i) Law on Environmental Protection and Natural Resources
Management; (ii) Law on Water Resources Management; (iii) Sub-Degree on Water Pollution
Control; (iv) Sub-Degree on Solid Waste Management; (v) Sub-Decree on EIA Process; and(vi) Sub-Decree on Air Pollution and Noise Disturbance Control. To abide by these legal
frameworks, stakeholders (both public and private sectors) pay more attention to implement
them based on their functions, and the national strategic plan (NSDP, 2006-2010) tocontribute the application of poverty alleviation in parallel with the initiative of environment
and the sustainable development.
Sub-Decree on Water Pollution Control
In the context of specific water environment protection and conservation, this report isfocused mainly on the Sub-Decree on Water Pollution Control 3 , e.g. its stipulations andapplication to various activities and/or sources, which cause the degradation of water quality
and aquatic life as well. The Sub-Decree on Water Pollution Control (SWPC) has establishedbased on the stipulation in Article 13, Chapter 5 of the Law on Environmental Protection andNatural Resources Management.
The Sub-Decree aims to minimize and phase out various activities that tend to pollute and/or
polluted public water areas, including improve wastewater management for sustaining goodwater quality suitable to human desires. The standard for discharging of effluent into public
water areas or into sewer, and the standard for water quality at public water areas forbiodiversity conservation and for public health protection.
To abide by the SWPC, MoE officials do a monitoring and control programme at various
pollution sources such as: factories, handicrafts, hotels, etc. Two sub-programmes are being
implemented at pollution sources: (i) a routine effluent monitoring at normal factories, hotels,
etc., is conducted within an interval period of 90 days; and (ii) a routine effluent monitoring atfactories those use chemicals and/or chemical compounds for their production, is taken in aninterval for 45 days. This application is done in order to ensure treated wastewater which isdischarged to receiving sources without impact to the environment and public health, as

It was approved by the Council of Ministers on April 06, 1999

-149-

stipulated in the Article 19 of the SWPC: "The Ministry of Environment shall take sample atevery discharge point of pollution sources. The owner or responsible person of pollution
sources shall collaborate with and facilitate the environmental official to take sample while
carrying out their technical task".
MoE officials within the monitor and/or control programme, take effluent samples andanalyze in order to identify a nature quality of discharged effluent at respective pollution
sources. If discharged effluents were found to be exceeded the standard, the MoE, incomplying with the Article 23 and Article 24 of the SWPC, has to instruct owner to properly
treat those effluents before discharging to receiving sources, and vice versa, a penalty will bedone by case.
Article 23: The owner or responsible person of the pollution sources as stipulated in thearticle 11 of this sub-decree shall: be responsible for determining the method of the treatment and the discharge of theireffluent so that it responds to the effluent standard as stipulated in the article 4 andarticle 5 of this sub-decree as well as the standard of pollution load as stipulated in
the article 7 of this sub-decree; have enough facilities and means to prevent the pollution of the public water area
when there is eventual danger caused from his/her pollution source; and hold the responsibility for installing an equipment for measurement of flow,
concentration and amount of pollutant contained in his/her effluent and also keep theresult for record keeping.
Article 24: Even if it is found out that the discharge of effluent from any pollution source do
not respond to the effluent standard as stipulated in the article 4 and article 5 or is not in
consistence with the pollution load standard as stipulated in the article 7 of this sub-decree,
the Ministry of Environment shall:

issue a written order requiring the owner or responsible person of such pollution
source to correct the violation activities immediately within a specified time period, if
that activity has not caused a harmful impact to human health or an adverse effect tothe water quality yet; andissue a written order requiring the owner or responsible person of such pollution
source to stop his/her activities temporarily until the violation is corrected, if that
activities cause an adverse impact to human health and water quality.

On the other hand, based on the Article 31 and Article 32, in Chapter 6 of the SWPC, if water
environment at public water areas 4 are polluted, MoE officials have to do an inspection andassessment the scope of water and environmental pollution in order to effective take action tominimize and eliminate these negative impacts, in closed collaboration with inter-ministries
and local authority.
Article 31: Where if there is complaint or report that any source of pollution discharges
effluent containing substance which cause danger to animal or human health or public
property or causes pollution to any public water area, the Ministry of Environment, in
collaboration with concerned ministries, may enter the site of this source of pollution andconduct inspection and take sample for testing.
4River, sea, lake, stream, creek, pond, canal and so on-150-

Article 32: In the case of serious accident or imminent danger resulting from pollution at
public water area, the Ministry of Environment shall make urgent inspection on the above
problem and shall inform the concerned ministries and local authority.
Besides effluent control and monitor 5 , MoE officials applies the Article 26 and Article 29 of
the SWPC, to monthly monitor/control some main watercourses are located surrounding
Phnom Penh Municipality (Mekong river, Bassac river, Sap river) and Chhnok Tru area
(Tonle Sap Lake).
Article 26: The Ministry of Environment shall regularly control and monitor the situation of
the water pollution at public water areas throughout the Kingdom of Cambodia in order totake measure to prevent and reduce the water pollution in public water areas.
Article 29: Even if it is fount that any public water areas is suffering of pollution which
could threaten human life or bio-diversity the Ministry of Environment shall immediately
notify the public about this danger and shall take measure to prevent the water pollution andto restore the water quality of such public water areas.
The MoE also provided a license/permission towards the discharge of solid and liquid wastes
as requested by factory/enterprise owner, after finding the discharging does not impair to theenvironment based on the environmentally sound management.
Law on Water Resources Management
The Law on Water Resources Management was prepared by the Ministry of Water Resources
and Meteorology (MoWRAM), and it has adopted by the National Assembly in 2007. The
general purposes of the law aim to foster the effective management of the all kind water
resources of Cambodia to attain socio-economic development and the welfare of the people.
Relevant activities to water quality management were found in the Article 22, Chapter 6 of
the Law. This Article stipulated as below:"Various discharge, disposal or storage of hazardous substances or wastes whichmight impact to water quality, human health, animals and plants shall ask for apermission or license.
Above captioned hazardous substances or wastes by types and technical standard for
effluent discharge will be identified by the Sub-Decree. All application of this Article,
the MoWRAM shall consult with inter-ministries."
Under the support of water quality monitoring network 6 , officials of the MoWRAM has takenwater sample at designated sampling stations to analyze since 1993. Historically, theprogramme has commenced since 1993 under the MRC support: (i) 05 stations were operated
in 1993; (ii) 06 stations were operated in 1995; and (iii)there are 11 stations are being
operated. Remarkably, the stations are classified to primary and secondary stations. There are:(a) 19 stations so-called as primary station (10 existing and 9 new proposed stations); and (b)2 stations for secondary network (1 existing and 1 new proposed stations). The primary5

One main MRC Programme-151-station was set up to monitor and control various transboundary issues, basin-wide
significance.
Conclusion
The efforts in protecting and conserving the environment and water environment are being
conducted under closed collaboration with stakeholders, including international communities
with remarkable outcomes. However, some constraints are recognized and required to
improve from now on such as: (i) capacity building and institutional strengthening; (ii)technical supports from international communities/donor; (iii) public awareness raising byother doable means and public participation; (iv) strengthening the carrying out ofenvironmental legal instruments; and (v) closed cooperation among countries in the region.

Introduction
The Ciliwung River Basin with an area encompassing 347km2 starting upstream at Tugu
Puncak, Bogor Province until downstream at the Jakarta Bay area which acts as the River
Basins outlet. The growing development at the River Basins, from the upstream area until thedownstream area is extremely rapid due to the increasing rate of population caused by thehigh developments in the JABODETABEK (Jakarta, Bogor, Tanggerang and Bekasi City)
area.
The development that is being done inside the Ciliwung River Basin area causes the decreaseof the lands capability in absorbing water, and thus lowering the surface protection of the land
from erosions, which in the end causes the rate of runoff and erosions. The floods in Jakarta,
the decrease of river water quality, landslides and droughts happens to be an indicator of
failure in managing natural resources for the population.
On the other hand, the usages of water resources from the Ciliwung River have not yet reachan optimum level. For example, the clean water usage in DKI Jakarta reaches 413 million
cubic meters a year, but the clean water supply from the District Water Utility DKI Jakarta’s
reservoirs is limited at 200 million cubic meters each year. In short, the rest of the 213 million
cubic meters of clean water needed by DKI Jakarta is dependent on underground water
reservoirs. Based on a yearly debit count, the water resources from the Ciliwung River, to be
exact 500 million cubic meters of water each year, is wasted to the ocean. The same also
happens to the Grogol, Pebauran and Pesanggerahan Stream that posses the combined
potential of 300 million cubic meters a year. To sum it up, over 800 million cubic meters
worth of water resources that is wasted to the ocean.
The other problem is the change of land development happening around the River Basins
Area. The change in land development around the River Basin Area during the last three
decades happens very rapidly, the conversion from the land full of vegetations into housing
and tall buildings increased without control. The results are the decreasing quality of support
from the ecosystem thus creating critical lands, the decrease in land fertility and water quality,
drought during the dry season and floods during the wet season. Seen from the amount offlow rate, evapotranspiration and infiltration alongside the debit fluctuation index, planting
vegetations in open lands like bush fields, meadows, and unused land, are the most viable andeffective choice to defend the hydrology functions of the River Basins.

The Capacity Limit of Pollution in The Ciliwung River
The entire length of the Ciliwung River from upstream until downstream reaches 89
kilometers. Flowing through a District two Cities and one Province, which are; The District ofBogor, The City of Bogor, The City of Depok, and the Province of DKI Jakarta.

Abstract
A methodology has been developed for the removal of arsenic (As) and manganese (Mn) fromunderground water using natural manganese dioxide (MnO2) and diatomite mineral basing on
the adsorptive process. The results showed that 90-96% concentration of As and/or Mn had
been removed from water samples by MnO2 and diatomite adsorbent materials. After treating,the concentration of As and Mn is lower than Vietnamese underground water quality standard(0.05 mg/L for As and 0.1 mg/L for Mn). Natural MnO2 and diatomite mineral are able toremove a total of As (III, V) without the oxidation reagents. The removal of As and Mn byusing diatomite is more efficient than using MnO2. Using the nature MnO2 and diatomite
mineral are extremely efficiency for removing As and Mn in the underground water.
Keywords: Arsenic, Manganese, Manganese dioxide, diatomite mineral, underground water,
adsorptive method
Introduction
Arsenic contamination in underground water was found in various countries in the world
as Bangladesh, India, China, Mexico, America and ect. About 30-40 million people of
Bangladesh, 13 million people in America, are now at risk of Arsenic contamination.
Arsenic and concentration at higher level than WHO recommended value is found of 51%
in the tube-wells in Bangladesh [1]. The geology of the Red river delta in Vietnam, likethe geology of Ganges River in Bangladesh, also has been finding the arsenic
contamination in underground water in some provinces as Hanoi, Hatay, NamDinh,
HaNam and etc. New investigations have shown potential problems related to thepresence of arsenic in alluvial deposits in the Red River region and in tube wells pumping
water from lower aquifer. This requires further study and careful assessment. In addition,
manganese level above the admissible standards are found both in the Red River and
Mekong River Delta [2].The arsenic contamination survey data in 351 tube wells, theresults showed that 351 water samples in which 25% have 0,05 mg/l higher concentrationof arsenic contaminated and 68% are 0,01 higher than permitted Vietnamese standard[3].Using arsenic and manganese contaminated water source for a long time will cause tiredness,
affect nervous system, even stomach cancer and other internal organs [4,5].
To eliminate arsenic and manganese from water source, development of feasible technologies
to their treatment process as well as house-hold scale is essential requirement in Vietnam [6,7].Therefore, study and assessment of the nature MnO2 and diatomite mineral adsorptive abilities totreat Mn and As total in underground water was carried out. Those processing technologies are-160-

simple, low-priced, and easily-operated. Utilizing mobile and statically absorptive ability is amethod of assessing the arsenic and manganese eliminating process from underground water bydermining the maximum adsorption capacity into the nature MnO2 and diatomite mineral which isinvestigated with hopes to contribute a part of technology and science to solve this urgent
problem.
Experimental
The MnO2 and diatomite mineral were pulverized from available raw materials. Arsenic andmanganese solutions were prepared by diluting the initially standard solution of 1 g/L concentrationfrom Merck Chemical Co. Ltd. All other chemicals were of analytical reagent grade. An atomic
absorption spectrophotometer system (AAS) using graphite and flame techniques was used tomeasure As and Mn.
Determination of As and Mn by statically absorptive method
Adsorption isotherm is a kind of graphic representing the relation between 1/a and 1/c(inversion of adsorption capacity of adsorbent material and inversion of concentration ofadsorbent at the level point). This diagram can present the maximal adsorption capacity andconstant Longmuir KL for every material. Basing on experimental result, the adsorptive
isotherm of metal ions (As and Mn) and the maximal adsorptive capacity are established. The
adsorption isotherm of As (V) on every material can be drawn and the maximum adsorption
capability is of Arsenic. Therefore, adsorbent capacity of Arsenic on different material is able
to be assessed.
Preparation of sample (2.1*):
Firstly, 1g of MnO2 and /or diatomite mineral was poured in to a beaker, which previously
contained 100 mL of a mixed solution of 0.1 mg/L arsenic and 4 mg/L manganese. The solution
was mixed and stirred gently with constant speed for 3 hours. Filtering this solution, As and Mn
were determined in extracted solution.
Secondly, 1g of MnO2 and /or diatomite mineral was poured in to a beaker, which previously
contained 100 mL of 0.1 mg/L arsenic solution or 1 mg/L manganese. Next, the solution was stirred
gently with a constant speed for 72 hours. Filtering the solution, As and Mn were determined in thatextracted solutions.
Determination of As and Mn by mobile absorptive method
Prepare experiment: Put 10 g materials (means 7.5 cm3 for capacity) to column, whichcontained glass wool. The solution, having As and Mn is poured into the column with flowrate as 1.6 mL/min. After every 24 hour, check sample and analyze content of Arsenic andManganese. This experiment is illustrated as the below figure 1.

The experimental condition for Arsenic treatment:
The condition for As treatment is quite similar. As initial concentration (C0) is 0, 1 mg/l.
Asd1-01, Asd1-02 ... Asd1-240 is the sample mark, corresponding to adsorbent reduction
time. The results in table 2 shows that the concentration of As has not much been removed-162-

after 10 days for using MnO2 ore. This result indicated that almost As was not adsorpted
into MnO2.
Investigation of the adsorptive ability of MnO2 and diatomite ore for removing arsenic andmanganese in the under ground water by statically adsorptive method
For determination of Mn: Sample using diatomite natural coded Do-Mn-03 and anotherusing manganese dioxide coded M-Mn-03. Soak 1g materials into 100mL of Manganesesolution which has 4mg/L of concentration. The procedure is described above (2.1*). The
results in table 3 indicated that Manganese was well treated by Manganese dioxide anddiatomite natural. It means MnO2 and diatomite ores are very good at treating Mn in thewater. MnO2 is not only oxidized but also adsorbent material.

For determination of As: The condition for As removal is similar as Mn. 100mL Arsenic
with concentration of 0,1mg/L is stirred with constant speed in 3 hours. Result in table 4
showed that the absorbent ability of As into MnO2 was very good. Processing efficiency
was nearly 97% and concentration of Arsenic in sample after treatment was below
Vietnamese standard. Arsenic is well treated by diatomite due to the high As adsorption
capacity of diatomite. Possibility, diatomite natural was made up of many other mineralmaterials like Al2O3, Fe2O3, betonies and ect.
Gauge adsorbent isotherm and determine maximal adsorption capacity of As and Mn ontosome materials
To make the calculation of adsorptive of material, it is necessary to identify the maximal
adsorption capacity of substance on materials basing on adsorbent isotherm. Figure 2 isillustration of adsorbent isotherm of As onto MnO2 while figure 3 is that of As onto
Fe2O3/diatomite natural. Adsorbent isotherm of Manganese on MnO2 ore is in figure 4 andfigure 5 is that into diatomite natural.
Study results showed that As treatment efficiency was high up to 80% with adsorbent
capacity calculated by Longmuir formula 1:
Am=2,08mg/g (y=1,535x+0, 48)(1)
The adsorptive of Fe2O3/Diatomite is dependent on ·OH group, which adhesion onto
diatomite surface, can be replaced As in that. The adsorbent ability of arsenic into diatomite ishigher than that intoMnO2. The maximal adsorbent capacity (am) can be calculated byformula 2
Am = 2, 5 mg/g (y= 20,03x + 0,406) (2)-163-

Figure 4 can be explained that MnO2 is oxidability and minus chargeable, therefore, it can be
attracted Mn2+ ion and created Mn2O3. Maximal adsorption capacity calculated by Longmuir
formula 3:
Am=12,7mg/g (y= 10,29x + 0,079) (3)Therefore, the adsorptive of Diatomite natural onto Mn is apparent (Fig. 5). At the moment ofinvestigation, Oxidized Mn2+ and dissolved oxy possibly appeared in this solution, even low
concentration of Mn2+.
It is due to adsorption and flocculation ability of Diatomite or Mn (OH) 4 which was createdthrough oxidization process which played an important part for Mn oxidization process.
Adsorbent capacity of Mn is calculated by Longmuir formula 4:
Am=15, 15 mg/g (y= 7,508x + 0,066) (4)Conclusion
The adsorptive ability of MnO2 for manganese removal in underground water by mobile
adsorptive method is very good. Using 10 g material, it can treat 1mg/L Mn with thetreatment productivity is of 99.9%.This method can not applied to As case.
The adsorptive ability of MnO2 and diatomite ore for arsenic and manganese removal inunderground water by statically adsorptive method is excellent. It means MnO2 and diatomite
ores are very good for Mn treatment in the water. Manganese dioxide is not only oxidized but also
adsorbent material. Arsenic is well treated by Diatomite due to the high As adsorption capacity of
Diatomite.

-164-

Those above results proved that natural manganese dioxide, diatomite mineral werepotential adsorbent materials which could be applied to treat Mn and As in water source.
Using manganese dioxide and diatomite mineral would concurrently treat both Mn and As
in the supply water.

Abstract
Over the last two decades, intense urbanization in Delhi area created several cut slopes of therugged topography. Iso-contours and multi-component mixing models of pollutants andisotopic composition of groundwater provided a unique understanding of the pollutants
dynamics in groundwater. Over 60% of the wells have become vulnerable to increased
chloride and nitrate contamination based. The major sources of chloride and nitrate areanthropogenic wastes, landfills, sewage irrigation and sewage treatment plants, turf grass
fertilizer and surface water runoff. 18O isotope and major elements that accompany in the
groundwater may distinguish sources of nitrate with less ambiguity, under different land use
conditions. Cl, Na, Mg, Ca, SO4 and NO3 show promising results as nitrate tracers on ternary
diagram and through element vs. element plots. Additional Ca2+ may be released to
groundwater by corrosion of subsurface concrete materials. Guidance has been provided on
the overall approach for protection of groundwater resource.

Introduction
Over the years, increase in population, urbanization and industrialization in Delhi area createdseveral cut slopes of the rugged topography. Indiscriminate disposal of anthropogenic wastes
and leaching of pollutants from these resulted in an ever-increasing threat to the quality ofground water resource base. Large-scale groundwater withdrawal for domestic, irrigation, andindustrial purposes lead to widespread decline of ground water table. For protection ofgroundwater from pollution, it is a matter of concern for the planners and decision makers toclearly characterize the groundwater renewal, quality of water and causes of its deterioration,
sources of pollution, trace the movement of pollutants and containment of spreading fromknown sources. The characteristics of pollutants level and transport in groundwater areassociated with variations in one or two parameters at one scale and several parameters at
another scale. While, a broad qualitative understanding of most of the aforementioned effects
is known, most of the various parameters and physico-chemical process as a whole in thehidden complex groundwater system are not completely understood. Iso-contour diagrams
and multi-component mixing models of pollutants and 18O isotopic composition ofgroundwater along the flow path provided a unique understanding of the groundwater flow
system and its vulnerability.
Physiography, Geohydrology and Climate
The semi-arid Delhi region (Figure-1) (area: 1483 Sq.Km. between 28o24'17"-28o53'00" Nand 76o50'24"-77o20'37" E), situated on the banks of the river Yamuna which flows from
north to south, is a part of the Indo-Gangetic Alluvial Plains.
-166-

The aquifer disposition in the area is overlain predominantly by sand in the top 20-30 m, andclay and kankar below that. The Alluvium thickness in the area varies from 100 m to morethan 300 m and groundwater occurs under semi-confined conditions. The hydrogeologicalsituation is characterized by the occurrence of alluvial and hard rock formations.
The climate of the region is semi-arid. The average annual rainfall (1931-99) is 711 mm, mostof which falls between June to September and is generally erratic, infrequent and heavy
sometimes. The average normal rainfall during July, August and September is 192.3 mm,
192.4 mm and 139.6 mm respectively. The mean minimum and maximum temperatures are
18.7oC and 30.5oC respectively.
Analytical Methods
Through extensive field survey and topographic survey, representative sites under changing
land use were selected, geographically equitably distributed covering the area, representing
various geohydrological conditions. Groundwater samples were collected at sixty-sevendifferent locations during June-July, 2003; at hundred different locations during June, 2004, at
84 locations during March, 2005 and at 84 locations during October, 2005.
Temperature, pH, specific conductance were measured in the field. The samples wereanalyzed as early as possible for the major anions (HCO3, Cl, NO3 and SO4), cations (Na, K,
Mg and Ca), and electrical conductivity by standard methods. The analytical precision for themeasurement of major ions is generally kept within ± 5% and expressed in mg/l or meq/l. The
18 16
O/ O ratio was measured following a modified Epstein-Mayeda technique and using
Micromass Isotope Ratio Mass-Spectrometer, by equilibrating a tank CO2 gas at 25°C. The
isotopic composition of water samples is expressed in terms of per mille deviation (δ ‰) withrespect to the isotopic ratio of the reference Standard Mean Ocean Water (SMOW). The
analytical reproducibility of the laboratory standard is ± 0.1‰.

-167-Groundwater isotopic and chemical composition

The isotopic data reveals that the aquifer in the studied area does not constitute a
homogeneous system in its lateral extent. The groundwater recharge variation (<1% to 66.0%)
from location to location, and pumping induced groundwater intermixing through different
flow pathways (Datta et al, 1996), result in wide range of spatial variations in the stable
isotope (18O) signatures of groundwater, with δ18O values as highly enriched + 0.59‰ to as
depleted as – 7.59‰ during 2003-04; from –0.60‰ to –7.70‰ in March, 2005, and –1.80‰
to –8.10‰ in October, 2005. In general, the groundwater isotopic composition is relatively
enriched as compared to the long-term weighted average value (-6.09‰) of Delhi rainfall(Datta et al, 1991). The groundwater are mostly alkaline with pH ranging from 6.9 to 7.7, andare moderately to highly saline, with EC ranging from 567-10340 umhos/cm in northernparts; 440-11944 umhos/cm in northwestern parts; 810-15370 umhos/cm in western parts;
680-2420 umhos/cm in southern parts; 550-3231 umhos/cm in eastern parts and 764-6950
umhos/cm in City parts. The Chloride levels range from 10-7160 mg/l in northern parts; 104100 mg/l in northwestern parts; 50-860 mg/l in City area; 60-6080 mg/l in western parts; 10280 mg/l in southern parts and 10-830 mg/l in eastern parts.
Large part of the area to the west of the ridge is severely affected by nitrate pollution ofgroundwater (Datta et al, 1997), exceeding the WHO prescribed maximum permissible limit(45 mg/l) in drinking water at many places. During 2003, the Nitrate levels in groundwater
ranged from <1-135 mg/l in northern parts; <1-159 mg/l in northwestern parts; 2-32 mg/l inCity area; 2-716 mg/l in western parts; 19-303 mg/l in southern parts and 1-69 mg/l in easternparts. During 2004, the Nitrate levels in groundwater ranged from <1-197 mg/l in northernparts; <1-193 mg/l in northwestern parts; <1-433 mg/l in City area; 1.5-445 mg/l in westernparts; 2.2-173 mg/l in southern parts and <1-158 mg/l in eastern parts. During March 2005, theNitrate levels in groundwater ranged from <1-250 mg/l in northern parts; <1-220 mg/l innorthwestern parts; 4.9-958 mg/l in City area; 7-504 mg/l in western parts; 24-465 mg/l in southernparts and <1-144 mg/l in eastern parts. During October 2005, the Nitrate levels in groundwater
ranged from <1-7.4 mg/l in northern parts; <1-14.5 mg/l in northwestern parts; 1.6-387 mg/l in City
area; 2.5-82 mg/l in western parts; 2.5-26 mg/l in southern parts and <1-35 mg/l in eastern parts.
EC, Chloride and Nitrate levels show an increasing tendency during the last decade in thenorthern parts, in the southwestern parts and in the western parts. Chemical composition of
the groundwaters, in general, remained more or less the same from year to year.
Isotopic distribution and chloride dynamics in groundwater and recharge zones
Superimposition of δ18O (‰) distributions on the Surfer-8 based topography model suggeststhat the pattern of δ18O (‰) distributions has remained unchanged from year to year (Figure1). But, groundwater in 2004 and pre-monsoon 2005 is highly saline, contaminated andisotopically enriched, as compared to rainwater mean δ−value of -6.09‰, suggesting selection
effect in favour of isotopically enriched rainfall in contributing depression focused recharge,
with longer time stay on low elevated land. Post-monsoon 2005 is relatively depleted,suggesting dilution effect due to lateral flow from surrounding areas, as observed earlier(Datta et al, 1994).
In the aquifer, adjacent to the western bank of the Yamuna river at some stretches, similarly
enriched 18O composition of both river water and groundwater compared to that of rainwater
during pre-monsoon, 2005 suggests that the river water recharges the groundwater after being
subjected to evaporative effects. However, relatively depleted 18O composition of both river-168-

water and groundwater during post-monsoon suggests fresh rainfall recharge to thegroundwater in these locations, and possibly contributions from the transport of the top layersof the groundwater from the nearby surrounding areas, as induced by pumping. A simple
mixing model (Datta and Tyagi, 1995), based on the spatial and depth variations in 18O/16O
ratio of groundwater and canal/river water, considering equal inflow of groundwater throughthe screens of the tubewells, indicated that canal/river water contributes to the groundwater
recharge upto 5-10m depth of the aquifer adjacent to the canal/river.
Moderate to highly saline groundwater occurrence suggests that the rainfall recharge is very
limited and that groundwater flushing is incomplete. Iso-contouring of chloride and nitrate
dynamics (Figure-2 & 3) indicates that from 2003 to 2005, there had been lateral extension ofhigh pollutants plumes towards the central urban parts along specific flowpaths, possibly
induced by withdrawal not in balance with recharge. The chloride distribution further suggeststhat due to excessive concretization of the region, recharge area from direct infiltration of
rainfall has reduced considerably and changes from 2003 to 2005, and the potential rechargezone remained confined only in the piedmont areas of southern parts. During 2003, there aresmall patches of potential recharge zone along the western Yamuna canal almost on theboundary separating the northern and northwestern parts and adjacent to the Yamuna river in
the northern parts. Another recharging zone is along the southern and eastern boundary ofsouthern parts.

-169-

On a regional scale good positive straight-line relationships between groundwater Cl and δ18O
(Figure- 4) indicate multiple source of high salinity groundwater mixing with good quality
water along two or more visualized specific flow pathways, due to changes in the hydraulicheads (Datta et al, 1996), induced by indiscriminate pumping. Except in southern parts,
eastern parts and City area, significant variation in groundwater chloride with almost nochange in 18O isotopic composition suggests salinity increase contributed by verticalinfiltration of chloride containing chemicals in soil with rainwater or irrigation water. The
lateral flow water also carries contaminants alongwith it through specific flow-pathways(Datta et al, 1996), influenced by mixing and the extent of the hydrodynamic zones (asindicated by small isotopic gradients).
Identification of sources of recharge based on major ion chemistry
AQUACHEM based major-ion trilinier diagrams (Figure-5) indicates that the groundwaters
have different chemical compositions, viz., Ca-Mg-HCO3; Na-Ca-HCO3-Cl; Mg-Na-HCO3;
Na-HCO3; Na-Cl-HCO3; Na-Mg-Cl; Na-Cl and Ca-Mg-Cl. While, Calcium bicarbonate water
is originated as rainfall-derived recharge, over decades to centuries, Calcium-sodium
bicarbonate water, are more likely derived from recharge of rainfall that carried saline water
mixing alongwith. Since, the clay mineralogy of the area indicates presence of 60% to 80%
Illite (Datta and Tyagi, 1996), which apparently is highly resistant to weathering process, theabundance of (Ca+Mg) in most of the groundwaters in the Delhi area can be attributed tomainly carbonate weathering, as observed from earlier studies (Datta and Tyagi, 1996).
Presence of ‘Kankar’ carbonates in the alluvial sediments and occurrence of metamorphosed
dolomitic limestones in Delhi Aravalli rocks could favour this process.In addition to this, thegroundwater chemistry seems to be significantly affected by the dissolution of concretematerials. Additional Ca2+ may be released to groundwater by corrosion of subsurface
concrete materials such as building foundations and basements.

-170-

Very highly saline waters (EC>10000 μmhos/cm) are of Na-Cl type. Moderately saline
groundwaters (EC: 3000-6000 μmhos/cm) are of Na-Mg-Cl type. However, sodium shows nocorrelation with salinity (Electrical conductivity). Highly correlated linear trend between Na
and Cl (Figure-4) indicates mixing of two groundwater bodies with different end member
composition (i.e. fresh and saline). It is interesting to observe that in every year, most of thegroundwater samples lie below the equiline in the scatter diagram of Na vs. Cl, suggesting
influence of anthropogenic activities. Groundwaters with low SO4 and high Cl probably
indicates localized SO4 reduction. The very high Cl and SO4 concentrations in some of thegroundwaters may be related to the long history of evaporation and to oxidation of reduced
sulphur gases from land in the relatively lower elevations of flood plain regions, (Datta andTyagi, 1996). Further the possibility of contribution from anthropogenic sources can not be
ruled out.
In ground water of the northwestern and southwestern parts, Sodium-chloride water might
have been acquired by mixing with a large component of relict saline water in the deep
aquifers (60-200ft) during geologic time. Calcium-magnesium-bicarbonate-sulfate water
genesis may be due to longer periods of weathering in contact with aquifer sediments. The
groundwaters, plotted on the trilinear diagram on a mixing line between Calcium-sodium-171-bicarbonate and Sodium-Chloride waters, represent the continuum between rainfall-driven
recharge, and relict saline water. The ground waters with mixed cation- bicarbonate andmixed-cation bicarbonate-chloride water, found in surface water or shallow ground water,
represent mixtures of various waters (Figure-6). In contrast, mixed-cation bicarbonate waterwith "depleted" stable isotopic signature, were found both very shallow (15 ft) and relatively
deep (60 ft or greater). The deeper mixed-cation bicarbonate water might have evolved bygeochemical interactions with aquifer sediments. Ternary diagrams of the major cations andmajor anions show that agricultural land use produces calcium-sulfate type water due toliming and the application of fertilizers. Residential land use produces water more enriched in
sodium and either chloride or bicarbonate, due to an increased contribution of road salt, and inpart to the elevated levels of these ions in sewage plumes.

Concluding remarks
The study establishes that groundwater has become more vulnerable to contamination andisotope studies should be conducted as part of comprehensive geohydrological andhydrochemical investigation of ground water vulnerability. There are indications of pollutants
transport from the western, northwestern and southwestern areas to the urbanized andoverexploited parts. In the northwestern and western parts, there is evidence of increasing
ground water pollution and leachate transport to ground water through surface drainage.
Further systematic research is needed on hydrogeologic characteristic of the groundwater flow
under natural and stressed conditions, dynamics of groundwater contaminants, and its linkage
with spatial and temporal variability in concentration, depth variation in contaminants level in
relation to well structure and casing conditions, denitrification potential of soil andgeohydrology in limiting contamination. Iso-concentration maps of contaminants levels ingroundwater should be prepared and revised time to time, in relation to the changes in landuse
pattern. The scope of this study has broader significance, since urbanization can place similarpressures on the water resources worldwide.

Actions for groundwater conservation(1) Declaration of the Groundwater Preservation City
Our actions for ground water conservation have started with the adoption of the “Declarationof the Groundwater Preservation City” by the city council in March, 1976. Protest movements
against apartment construction sites near the source of our drinking water stimulated the city
council to adopt said declaration. The following year, we enacted the Groundwater
Preservation Ordinance, organized an official office to oversee the groundwater system andextraction, and began to establish observation facilities.

*Groundwater is shared by 14 municipalities （ hereinafter referred to as Kumamoto
Region） including Kumamoto City, as well as a layer formed by Mount Aso’s eruption
provides the main aquifer for our groundwater.
*The Kumamoto Region receives 2 billion cubic meters of precipitation a year;
approximately one third of it evaporates, another one third of it flows into river, and theremaining one third of it, around 600 million cubic meters, forms groundwater.
*Of the total of 600 million cubic meters of groundwater, 46% are cultivated in paddy fields,
41% are cultivated in dry fields or grass fields, and 13% are cultivated in mountainous areas.
In other words, our agricultural land serves as the main source of the groundwater.
*Groundwater takes about 20 years to reach Kumamoto City from the outer rim of Mount
Aso.
(3)Mount Aso and the feudal lord Kato Kiyomasa
The volcanic Mount Aso experienced violent eruptions with pyroclastic flows four times from
270,000 years ago to 90,000 years ago, when the pyroclastic flow deposited and accumulated
to more than 100 meters in thickness, which would later serve to foster our groundwater.
In addition, about 400 years ago, Kato Kiyomasa, the feudal lord of Higo, present day
Kumamoto, promoted cultivating paddy fields in the surrounding land, which is easy topermeate with groundwater. This concept worked considerably well and allowed Kumamoto
access to a far greater amount of clean water.
In other words, the achieved system of creating groundwater in Kumamoto can be said to be a
combined balance of the “natural system” of Mount Aso and the “human efforts” made many
individuals such as Kato Kiyomasa.
(4)The current status of our groundwater
According to the municipal observation report, Kumamoto’s groundwater flow has beensteadily decreasing. There are two main reasons for this. One is the advancement ofurbanization; the other factor is the adjustments in rice production.
After the Second World War, the central urban area broadened with economic development.
Vast areas were laid with concrete or asphalt for urban expansion and it became difficult for
rainwater to naturally absorb into the earth. Groundwater has become harder to accumulate inrecent times.
In addition, as rice consumption in Japan has decreased, the amount agricultural land used as
paddy fields has also been reduced by 50 percent. This is a serious problem for Kumamoto
because our paddy fields are a major source of groundwater.
We have officially recognized the actual state of groundwater via observations, which haverevealed the nature of these problems, and have begun to promote effective groundwater
conservation measures which are in accord with the natural groundwater system.

(5)Groundwater cultivation which fully utilizes paddy fields
First of all, I would like to mention our programs of groundwater cultivation which utilize
paddy fields.
Science proves that the ancient paddy fields, which were cultivated by Kato Kiyomasa, thatare located in the towns of Ozu and Kikuyo, neighboring towns of Kumamoto City which lie
towards the center of the Shirakawa River, are precious groundwater recharge areas for
Kumamoto City. The city therefore concluded an agreement of groundwater conservation
with these two neighboring towns in January 2004. Furthermore, we have established asubsidy system which encourages farmers to irrigate their rice fields even after these fields
were no longer to be used to produce rice under the production adjustments. Currently, withthe aid of more than 400 farmers, we create more than 1,000 cubic meters of clean
groundwater a year. We also work with a coalition of upstream sites regarding these ancientand influential paddy fields by arranging exchange programs and promoting “local production
for local consumption”.
(6)Maintenance of watershed protection forests
Secondly, I would like to expand upon the maintenance of watershed protection forests.
Irrigation water for paddy field in the central part of the Shirakawa River is all derived from
Shirakawa River. To ensure a stable river flow and to create sufficient groundwater, we haveconcluded an agreement for forest maintenance with our neighboring towns and villages andstrive to maintain 656 hectares of watershed protection forest. In addition, we aim for local
forest development with the support of volunteer citizens.
(7)Fostering a rainwater percolation
Third of all, we have addressed the issue of groundwater cultivation in order to foster a
rainwater percolation in the urban areas. We have also implemented an original subsidy
system for installing this rainwater percolation equipment or PVC greenhouses in dry fields
which help rainwater get adequately absorbed. Moreover, we revised the “Kumamoto City
Groundwater Preservation Ordinance” last July in order to ordain the practice of
implementing the equipment or facilities to foster rainwater percolation even whenconstructing new buildings, an approach that has never been used before in Japan.
(8)Development of the citizens’ movement for water conservation
Next, I will tell you about the citizens’ movement for water conservation.
The quantity of groundwater extraction in Kumamoto City is on a downward trend after
peaking in 1984. The quantity of the extracted water for industrial or agricultural use has also
declined; however, groundwater for use in everyday life, which accounts for 70 % ofgroundwater extraction in Kumamoto City, has not declined in quantity.
We have been promoting this water conservation movement and working towards efficientwater-saving methods at home with citizens since 2004. We have also made July a campaign
period for water conservation, having reported citizen water usage everyday, which we aim to
reduce the total amount by 10 % in 5 years.
(9)The Kumamoto Water Heritage Registration Program
I would like to continue by introducing you to the Kumamoto Water Heritage Registration
Program.
This program is designed to maintain the various local cultures and trades which are deeply-176-linked with our water, such as architecture, customs, or food, for future generations to come.
So far 43 concepts have been registered, and the bus tour to those Water Heritage sites is quite
popular among citizens.
(10)Establishment of the Kumamoto City Official Water Examination
Next, I would like to explain about the challenges faced in establishing the official water
examination. To conserve our water culture and pass it down to the next generations after us,
it is vital that we instill awareness into citizens about our current water situation of
Kumamoto. We have established the official water examination of Kumamoto City, withwhich you can enjoy learning about water of Kumamoto, and have been implementing thisprogram since last August.
With this examination, we can spread the knowledge about our water culture and enlighten
people about the challenges involved in maintaining our precious water supply. We promote
groundwater conservation while advertising Kumamoto City as a pure groundwater city.
(11)Environmental education and lifelong learning programs
We also work hard to provide environmental education and lifelong learning programs.
We created and regularly distribute supplementary readers for elementary students to learn
about water. Regarding lifelong learning programs, we have arranged some courses of waterthat citizens can take at home as well as offering them in various locations. These courses
contain topics such as Kumamoto’s groundwater, Kumamoto’s rivers, water conservancy,
Kumamoto Water Heritage, and the official water examination of Kumamoto. City employees
present these materials at schools or community centers.
(12)Kumamoto City won this year’s highest national award for water resource management,
the Japan Water Grand Prix.
This prize is to be given to a person or an organization who improve the distinguishedprograms regarding revitalizing water circulation and aim to achieve a Japan in the 21st
century where all water is safe, clean, and enjoyable.
This is because we are highly praised with our cross-administrative-district work forgroundwater conservation over the past 30 years combining citizens and businesses, such as
the establishment of the Groundwater Preservation Ordinance, groundwater cultivation
programs which fully utilize our watershed forests and paddy fields, and involve citizens’
movement for water conservation.
(13)The 100 best waters of the Heisei Year in JapanThe Ministry of the Environment has selected Suizenji Lake Ezu springs and Mount Kinpo
springs in Kumamoto City as two of the 100 best waters of the Heisei Year.
These two springs were valued because of not only their water quality and size but also
because of the communities’ or NPO’s proactive and continuing conservation activities forthem.
Message from Kumamoto City, home of the richest groundwater in Japan, to our Asianneighbors
As we have explained above, Kumamoto City is the most groundwater rich city in Japan.
However, there are currently many people who cannot obtain safe drinking water in Asia. We
strive to spread awareness of such water-related problems in Asia and are considering sharing
the information and message of our programs for groundwater conservation to other parts of
the world.

This year marks 400th anniversary of the completion of Kumamoto Castle, which was
originally built by the feudal lord Kato Kiyomasa. Honmaru Goten Palace has been restored
and it attracts many visitors from both Japan and abroad. You can see panoramic views ofdowntown Kumamoto City as well as Mt. Aso from main tower of the castle.
We hope everyone attending this forum today will visit Kumamoto someday, enjoy the
Kumamoto Castle or Lake Ezu or Mount Kinpo springs, and even enjoy tasting ourgroundwater that we feel so passionate about.

Abstract
Farmers' perceptions about groundwater and drinking water quality are important, which
influence their willingness to adopt protection measures either individually or collectively.
This study attempts to capture the factors influencing farmers’ perceptions and their
willingness to protect groundwater from nonpoint sources of pollution, and their willingness
to support the local government to supply drinking water through alternative arrangements.
Six villages are identified in the Lower Bhavani River Basin, Tamil Nadu, India on the basisof their long-term groundwater nitrate concentrations and sources of irrigation. A prestructured questionnaire survey (face-to-face interviews) has been administered to 395 farmhouseholds across six villages during June-July, 2006. Results show that farmers’ perceptionsof risks related to groundwater nitrate pollution vary across the villages, and mimic the actual
groundwater nitrate situation. Estimated results of binary choice Probit models show that
farmers from comparatively high groundwater nitrate contaminated villages are willing toprotect groundwater as compared to farmers from less affected villages. Demand for safe
drinking water varies across the villages, based on the variations of socio-economic
characteristics of the sample households and groundwater quality of the villages.
Keywords: Groundwater Quality, Nonpoint Source Pollution, Willingness To Protect, Rural
Water Supply, Subjective Risk Assessment, India.
Introduction
Pollution abatement strategies for water resources in India and other developing countries
have given priority to point sources of pollution. However, it is increasingly becoming
evident that improvement of quality of surface and ground water resources will also require
the control of pollution from nonpoint sources (NPS). Nonpoint source water pollution
control is particularly crucial in rural areas where groundwater is an important source ofdrinking water. In several parts of India, growing access to irrigation facilities along with
unbalanced and overuse of nitrogenous fertilisers, unlined and open storage of livestock
wastes, and insanitary disposal of human wastes have led to high concentration of nitrate ingroundwater. There is limited information on the level of pesticide contamination of water
sources. However, there is substantial secondary information on the level of nitrate ingroundwater as well as surface water.
Consumption of nitrate contaminated drinking water poses various short and long term healthhazards to various age groups (Fewtrell, 2004; WHO, 2004). Nitrate (NO3) concentration inwater used for drinking should be less than 50 milligram per litre (mg/l) (WHO, 2004). In-179-

India water having nitrate levels greater than 100 mg/litre is considered to be harmful, if used
for drinking (ISI, 1991).
Nonpoint Source Pollution Control Options
Due to large number of sources and diffused entry points, it is technically difficult andfinancially infeasible to monitor the contribution of individual nonpoint sources to theambient concentration (Dosi and Zeitouni, 2001). Though monitoring and taking regulatory
measures to protect groundwater is the responsibility of the Pollution Control Boards (Trivedy,2000), there is no legal provision to regulate individual polluters. As a result, pollution control
of nonpoint sources is mostly neglected in India. Economic instruments like nitrogen andpesticide taxes are not feasible in the Indian context at this time, although they have been usedin some European countries (Zeijts and Westhoek, 2004 and Rougoor et al., 2001). In India,
nitrogenous fertilisers have been subsidised to encourage use by farmers. This has led to
overuse of fertilisers by farmers and the consequent problem of nitrate pollution of thegroundwater (NAAS, 2005). Proper pricing of fertilisers may lead to more careful use(Chelliah et al., 2007). Voluntary approach like collective action to adopt best management
practices (BMPs) by the farmers may be a long-term solution to control NPS groundwaterpollution. Collective action is needed to ensure that restraint in the use of fertilisers ispractised by all the farmers in a particular village or area.
Environmental Sustainability of Sources of Drinking Water
One of the targets of the United Nations’ Millennium Development Goals (MDGs) is to“halve by 2015 the proportion of people without sustainable access to safe drinking water andbasic sanitation” (Target 10 of MDGs). Pollution from nonpoint sources (NPS) makes
groundwater resources unsuitable for drinking. Thus environmental sustainability of safe
sources of drinking water for future generations is at stake.
Environmental and natural resources conservation from quantitative depletion and qualitative
degradation, should be an integral part of any economic and development policy, which isalso one of the targets of United Nations’ Millennium Development Goals (Target 9).
Both qualitative and quantitative aspects of protection of drinking water sources need to beaddressed to meet the drinking water needs of the people. Major challenges that rural watersupply sector in India is facing today are not only to meet the large investment requirement toaugment the water supply, but also additional investment burden to tackle the water quality
related problems. Achieving equity and greater access to safe drinking water for a large
section of the populace will remain a distant dream, if we cannot protect our drinking water
sources from all possible sources of pollution. Since groundwater serves as a decentralised
source of drinking water in rural areas, the rural population become vulnerable to various
water-borne diseases when groundwater is polluted. And it is mostly the poor and marginal
section of the population who suffer the most, as they cannot afford to protect themselvesfrom the impacts of pollution.
Access to safe drinking water is vital for human well-being (UNDP, 2006). People exposed topolluted drinking water are vulnerable to various water borne diseases. Costs associated withmortality and morbidity of water-borne diseases are high. For example in India water borne
diseases annually put a burden of USD 3.1 to 8.3 million in 1992 prices (Brandon and
Hommann, 1995).

The Comptroller and Auditor General of India (2000) reports that about 10 per cent of water
sources in the state of Tamil Nadu are not potable due to excessive nitrate. The nitrateaffected belt is mainly in the western districts of Tamil Nadu. Foster and Garduño (2004)
reported elevated concentration of nitrate in drinking water wells during dry season atnumerous locations in Tamil Nadu. In Coimbatore and Dharmapuri districts of western zone,
more than 20 per cent of drinking water wells had nitrate concentration greater than 50 mg/l
and in large number of wells nitrate concentration exceeded 100 mg/l. They attributed
infiltration or leaching of nitrate from human and animal excreta as the major cause ofgroundwater nitrate in those areas. Controlling pollution from nonpoint sources will be thefirst step towards sustainable access to safe drinking water in rural areas. In this study, we use
the Lower Bhavani River Basin in Tamil Nadu as a case study of nonpoint source pollution.
Nitrate Pollution in the Lower Bhavani River Basin, Tamil Nadu
The Bhavani river is the second largest perennial river of Tamil Nadu, and one of the mostimportant tributaries of the Cauvery river. The Lower Bhavani River Basin is an extensively
irrigated area, and farmers apply nitrogenous fertilisers way above the doses recommended by
the Tamil Nadu Agricultural University (Shanmugam and Mukherjee, 2004). As a result highconcentration of nitrate has been reported both in shallow and deep aquifers. Secondary dataon groundwater quality indicates that the level of nitrates in the groundwater is high (> 100
mg/liter) in many pockets of Coimbatore and Erode districts of Tamil Nadu in which thebasin is located. Due to growing incidence of groundwater nitrate concentration in the basin,
the environmental sustainability of safe drinking water sources is at stake. In some instances
the public water supply authority has provided drinking water from alternative sources tonitrate affected rural habitations. However, a large section of the society is still dependent on
decentralised drinking water systems and exposed to high nitrate contaminated drinking water.
It is expected that drinking nitrate-contaminated water may have various short and long term
health impacts. However, due to inadequate secondary health information it cannot be
confirmed.
Objectives
Community participation in environmental conservation is a new area of research and it is in
this regard that this study attempts to understand (in ex ante) individual farmers’ perceptions
about groundwater quality, and factors which influence his/her individual decision to protect
groundwater either individually (through adoption of agricultural BMPs) or collectively - bysupporting local government to supply safe drinking water through alternative arrangements.
This is the first step to study the possible emergence of collective action. The decision tocooperate in collective action is an individual’s decision where his/her economic motives,socio-economic background and other factors play a crucial role. Apart from individual
specific factors, social connectivity (social capital) and factors like information/consultation
sources play a crucial role in his/her decision.
Methodology
To capture the spatial variations across the basin, we have selected six villages on the basis of
their water availability, sources of irrigation, intensity of agriculture (as measured by total
cropped area as a percentage of total area), intensity of irrigation (as measured by irrigatedarea as a percentage of total cropped area), long-term groundwater nitrate concentration andlevel of urbanisation. The villages differ in their sources and access to drinking water.
-181-

However, all the villages have access (to a limited extent) to safe drinking water from TWAD
Board’s Combined Water Supply Schemes (CWSS) running from the Bhavani river. Amongthe 6 villages two are from the Lower Bhavani Project (LBP) canal command area – Elathur(ELA) at the head reach of the canal and Kalingiam (KAL) at the middle reach of the canal,
two are from the old system – Kondayampalayam (KDP) depends on Arrakankottai canal for
irrigation and Appakoodal (APP) depends on the Bhavani river for irrigation and two are fromrain fed and groundwater irrigated area – Madampalayam (MDP) and Kembanickenpalayam(KNP). Apart from the sources of irrigation, villages differ with respect to their level ofurbanisation and socio-economic status. Appakoodal, Elathur and Kembanickenpalayam are
Town Panchayats (TP) and Kalingiam, Kondayampalayam and Madampalayam are Village
Panchayats (VP). Out of six sample villages from three irrigation systems – old system, newsystem and rain fed area - one TP and one VP falls under each of the system (Table 1).
Groundwater data analysis shows that Appakoodal, Kembanickenpalayam andMadampalayam have comparatively higher groundwater nitrate concentration - more than 50
per cent of the samples have NO3 concentration more than 50 mg/l. Elathur, Kalingiam andKondayampalayam have comparatively lower groundwater nitrate concentration - less than 25
per cent of the samples have NO3 concentration less than 50 mg/l. Average groundwater
nitrate concentration for Madampalayam is comparatively higher (for all seasons) than otherfive villages selected for our case studies.

A detailed questionnaire survey has been carried out among 395 farm households spread
across six villages in the Lower Bhavani River Basin during June to July, 2006. Bothqualitative and quantitative information collected through face-to-face interviews with thehead of the farm households. On an average 60 farm households were selected randomly fromeach of the six villages on the basis of their availability of own agricultural land and interestin the subject of our research. Voluntary participation of the farm households was sought forinterviews, based on their availability of time. Both the information leaflet and household-182-

questionnaire schedule were translated into Tamil, and a background of the objectives, scopeand coverage of this study was described before starting the interviews. Apart from household
questionnaire survey, various information related to land use pattern and drinking water
schemes/systems of the villages were collected from the village agriculture office and village
panchayat office respectively.
Results
The estimated results of binary choice Probit models show that:• Farmers from comparatively high groundwater nitrate contaminated villages correctly
perceive (subjective) their groundwater quality and they are willing to protect groundwater
quality as compared to farmers from less affected villages. Therefore, it shows that any
groundwater quality protection programme from nonpoint sources of pollution should take
into consideration the site characteristics and socio-economic characteristics of the
stakeholders.
• Farmers’ groundwater quality perceptions vary across the villages and mimic the actual
groundwater nitrate situation. Households depending on their socio-economic
characteristics, social- and information-network and the characteristics of the resource(alternative sources and quality of drinking water) derive a subjective risk assessment of
their groundwater quality. Regular monitoring of groundwater quality, assessment(objective) of risks of consuming contaminated groundwater and communication of risks tothe stakeholders could help the farmers to take measures/initiatives either individually orcollectively to protect groundwater from NPS pollution.
• Demand for safe drinking water varies across the villages, based on the variations of socioeconomic characteristics of the sample households and groundwater quality. However, withreference to farmers’ willingness to protect groundwater quality, their willingness to
support local government shows different results. For example, farmers from villages
having higher concentration of groundwater nitrate, are willing to protect groundwater
quality and reluctant to support local government. However, adoption of demand driven
approach for provision of drinking water may not be suitable specifically when the risk ofconsuming contaminated drinking water is not commonly perceived by the consumers, as
the presence of nitrate does not change the taste, odour, colour or any other commonly
perceivable quality/characteristics of drinking water.
• Farmers’ knowledge about impacts of agricultural practices on groundwater quality
significantly influences their perceptions about groundwater quality and willingness toprotect groundwater. Therefore, provision of agricultural information and education alongwith basic agricultural extension services could induce the farmers to protect groundwaterfrom NPS Pollution.
• Both socio-economic characteristics of the households and the characteristics of the subject(groundwater or drinking water) significantly influence the farmers’ perceptions.
Knowledge of agricultural BMPs and their impacts on environment positively influences
farmers’ perceptions and willingness.
• Farmers’ perceptions about groundwater quality influence their willingness to support local
government to supply safe drinking water. Irrespective of sources of drinking water,
farmers are willing to support local government• Memberships in social participatory institutions and sources of agricultural information,
significantly influences farmers perceptions and willingness.

The role of stakeholders and their voluntary participation in agro-environmental managementin general and water resources conservation/management in particular is a new area of
research, at least for a developing country like India. The study will be useful for policy since
there are many areas in India and other developing countries which are facing similar
groundwater pollution problems. The issue of groundwater pollution from nonpoint sources isa growing concern not only for a relatively water scarce country like India, but also for waterabundant countries around the world.

Abstract
Weihai as a coastal city in China enjoys the preferential policies and unique location, theurbanization and economy developed very fast, that also causes severe environmentalpressure especially for the water. Weihai introduces market mechanism into the water
management, using discharge fee, pricing, BOT, polluter pay principle, encourage the watersaving, solved the fund shortage problem, established a public-private partnership, though theGDP, urban population and developed urban area grow very fast, but the water quality
remains the same as before.
Keywords: market mechanism, water pricing, BOT, polluter pay principle, public-private
partnership
BackgroundWeihai is located in the eastern tip of Shandong Peninsula of China, opposite to the Liaodong
Peninsula, the Korean Peninsula and Japanese Islands across the sea. Weihai has a history ofover 600 years. It had been a small frontier town till the 1980s with a population less than
70,000.

-185-

In 1987, Weihai was founded as a prefecture level city. Three lower level cities are under its
jurisdiction; the total area is 5436 square kilometers, with a population of 2.47 million. Weihai
has 986km coastline with attractive beaches, beautiful landscape, numerous historic sites anda pleasant climate. The GDP was only 3.4 billion yuan in 1987, mainly from fisheries andlight industries, the environmental quality is one of the best in China, and these make Weihaia famous tourist city.
When China began to open up and move on to the current fast track to development, Weihai
as a new developing coastal city，enjoys many preferential policies and a unique location，
this lead to a rapid development for the city and economy. In 2007, compared with thefoundation of Weihai city in 1987, the developed urban area grew from13.1 to 109.0 km2; theurban population grew from 233,000 to 632,000; GDP grew from 3.42 billion yuan to 158.35
billion yuan. The GDP growth rate is 21 % annually. The rapid development also brings highpressures on the environment, especially the water quality.
Shandong peninsula is a water shortage area; the annual precipitation in Weihai is 770mm.
Because Weihai is a hilly land, most of the rainwater runs into the sea immediately, and there
is no river transfer water from inland to Weihai, the annual available water resource is only
548 m3 per capita, just about 1/4 of the China’s national average, which itself is only ¼ of theworld average. This means that the water resource per capita in Weihai is only 1/16 of theworld. But along with the rapid development of urban and industry, the water demand
increases rapidly. In the central city, the supplied running water was 6.90 million tons in 1987,
increased to63.30 million tons in 2007. Making the situation even worse, the scarce water
resource face severe pollution because the increased wastewater discharges from human andindustrial activities.
During 1999 and 2000, Weihai experienced a severe drought; the precipitation was 316 and
460 mm, only about 1/2 of the annual precipitation. The water level in the reservoir, the water
resource of the city, dropped to the bottom, the whole city faced a severe water shortage
problem. To ensure the residents’ daily water supply, the government limited the water use of
the factories; some big water consuming factories even were shut down. In the spring of 2001,
before the rainy season came, the whole city especially the mayor was greatly alarmed. The
rains finally came when the city had only 7 days of water left in the reservoir!
After this critical test, we thought about the water issue carefully. What are the problems?
How can we solve them? The mayor held several meetings focused on the water issue. He
directed the water resources, environmental protection, urban construction and industry
administration departments to carry out investigation, present their suggestions and discussthese with each other. We found: yes, Weihai is a water shortage area; that is God gives us. We
cannot change it. What we can do is increase the water use efficiency; protect the water
environment, keep all the water clean enough for use; explore new water resources. To
achieve this goal, introduce the market mechanism into the water environment management,
establish public-private partnership is the key instrument.

-186-

Description of the initiative
The initiative focus on the follow area:
Collect pollutants discharge fee, force the industrial structure reform
In Weihai, 2/3 of the running water is consumed by industries and the same percent ofwastewater discharged from industries accordingly. So reform of the industrial structure,establishing water saving industries in Weihai, is the key to solving the water shortage andwater pollution problem.
In China, we have a policy, if the factories discharge pollutants into the air, water body or soil,
they should pay the pollutants discharge fees to the government. The discharge fee calculated
according the concentration and volume of the pollutants. But in practice, in most of the cases,
because the local government leaders pay more attention on the economic development thanthe environmental protection, and the local environmental protection agency lack thetechnique and supervision force, this policy has not been carried out thoroughly. Before 2000,
the situation is almost the same in Weihai. After the initiative, the mayor pay more attention
on the environment; invested 8 million RMB, established a automatic-continuous air quality
monitoring system, installed 30 on line water quality monitoring equipment on main
wastewater discharge points; recruited 16 university graduated students, stressed thesupervision force, that makes the environmental policy be carried out more thoroughly. In
1999, the collected pollutants fee was only 2.5 million; in 2007, it reaches 16.8 million, 6.7
times than 1999. The enforcement of the environmental protection law forces the factories tochoose clean production, clean process, then improved the industrial structure.
In China, most of the town level cities have pulp & paper mills and ethanol factories. Theyuse grain stems to produce paper and use sweet potatoes to produce alcohol. In some area
they are the main contributors of the government revenue. But these industries consume a lotof water, discharge a lot of water pollutants, and create problems for water environment.
Before 2000, Weihai has 4 pulp & paper mills and 4 ethanol factories; they cause a bigpressure on the environment. We monitor their water discharge and collect discharge fee
stringently, makes them no much profit, combine with the national and provincial industrial
policies, these mills and factories were gradually be shut down. By 2000, only one pulp &paper mill was left. In 2001, we made the decision to shut down the last one. Now in Weihai
only allow use recycled paper to produce paper. This decision can save 3 million ton water ayear, reduce the same mount of wastewater discharge and improved the water environmental
nearby very much.
These years, because the preferential policy and advantage environment, many investors came
Weihai to open factories or do business. During the approval process, the relative departmentsof Weihai municipal government insisted on the principal of non-pollution and efficient wateruse, and refused to issue permits to polluting industry though it might make a big contribution
to the local revenue. During the last 7 years, we rejected about 230 projects with total
investment about 120 million USD.
Now the main industries in Weihai are electronics, garment, machinery manufacture,
medicine, food processing and service. This kind of industrial structure consumes less energy
and water resources, making the development more sustainable.

Using pricing mechanism, encourage water saving
Before 1978, China had a centrally planned economic system. After China open up to theoutside of the world, it began to conduct economic reforms, gradually changing the centrally
planned system to a market system. During the planned economic period, salaries were very
low, but the residents enjoyed subsidies for most of their living cost. The government owned
companies allocated apartments to their employees, charging only a very small rent. The
government also subsidized food and water. All the investment for water supply came fromthe government revenue, the price charged for the residents covered only a small part of its
real cost. In this case, there was no motivation for the residents to save the water in order tosaving their money.
After the economic reform, China follows market principle, began let the beneficiaries pay thecost. In order to stimulate public saving water, we gradually raise the water price. In 1999, thewater price for the residents was only 1.20 yuan per ton, now is 2.85 yuan that including 1.70
yuan for water supply, 0.8 yuan for sewage treatment and 0.35 yuan for water resources. We
also use the progressive pricing mechanism that means the more water you consume, thehigher of the water price is. For example, if a house uses more than 12 tons per mouth, theprice of the water will be double than 12 tons below. This mechanism is designed to protect
the poor and punish the waster. In 1999, the water price for factories was only 4.00 yuan perton, now is 6.85 yuan that includes 5.00 yuan for water supply, 1.10 yuan for sewage
treatment, 0.35 for water resources and 0.40 for other cost.
Now in Weihai, at the household level, most people use water saving equipment, change thescrew tap to one action tap, use urinals with a volume of less than 6 L. Some householders
even store the water after washing hands and vegetables then use it for flushing the urinal.
For industries, more factories use clear product process. The water is recycled, reused asmuch as possible. Some factories even take the sewage treatment plant as their water resource;
use the treated wastewater as cooling water or for other purpose. From 2002 to 2005, the 3heating & power stations in the central city invested 150 million RMB, changed the heating
system from supplying steam to circulated hot water that can save 1.5 million ton water every
year. Now the industrial water reuse rate is 93.14%.
The entire municipal infrastructure maintenance, like irrigation of grassland and trees, roadwetting, use recycled water. In municipal engineering, most of them use rainwater fromreservoirs and pools nearby. In down town of Weihai, along the coastline, there are several
large parks with grass and trees. Here we constructed pipelines under the ground andconnected the parks with a sewage treatment plant, use treated water to irrigate the grass andtrees. With this project alone we saved 0.16 million tons fresh water in 2007.
Using BOT method, absorb private company invest in the sewage treatment plant
In the early 1980s, after a careful study from both the environmental and economic aspects,
we found that compared with the individual sewage treatment system, the district sewage
treatment system has many advantages. It costs less, has higher efficiency, is easier toadministrate and the environmental quality is better. So Weihai government decided to use the
district sewage treatment system. According the urban development, landscape, sewage
discharge volume and water environment, we made a plan for sewage collection andtreatment plants construction, let the municipal administration bureau to construct the sewage
treatment plants accordingly. We do not demand the factories and hotels build their own-188-treatment facilities, except those factories, like electroplate plants, whose wastewater is notsuitable for the biochemical treatment method.
The No1 sewage treatment plant began to operate in 1985; that was also the No1 in Shandong
Province. At that time one could count on his fingers the total number sewage treatment
plants in China. Its capacity is 15000 t/d, total investment is 12 million RMB. The No2
sewage treatment plant began to operate in 1995, with a capacity of 80,000 t/d, investment is
120 million RMB. The first phase of No3 sewage treatment plant began to operate in 2000
with a capacity 10,000 t/d, investment is 50 million RMB.
When we constructed the No1 sewage
treatment plant in 1985, No2 sewage
treatment plant in 1995 and the first phaseof No3 sewage treatment plant in 2000, all
the investment came from the government
revenue. When we expanded the No2 andNo3 sewage treatment plants in 2005 and2006, we used the BOT (Build, Operation
then Transfer) method, absorbing private
investment in the city’s infrastructure. The
expansion of No2 sewage treatment plantinvested by a company headquartered in
Beijing. It takes care of all the design, construction and operation, the capacity is 40,000 ton
per day; the total investment is 62 million RMB. The beneficiaries pay the sewage treatment
fee, 0.91 yuan per ton. After 25 years of operation, the company will transfer the plant to the
local government with zero payment. The expansion of No3 sewage treatment plant is done
by a company headquartered in Qingdao. The capacity is 40,000 ton per day, total investment
is 61 million. The beneficiaries pay 0.93 yuan per ton. Its operation period is 25 years. Afterthat time, the plant also will be transfer to the local government with zero payment.
Using the BOT method, the government does not have to spend money, but solved the sewage
treatment problem properly. In 1999, the sewage treatment rate in Weihai was 59.99 %,increased to 83.56 % in 2007.
Follow the polluter pay principle, collect sewage treatment fee
Before 2005, in most of the cities in China, the running cost of the sewage treatment plants
was covered by the government; it was free of charge for both residents and factories that is a
big burden for the local government. In some cities, the local government constructed the
sewage treatment plant under pressure of environment with the assistance of central
government, but can not afford the running cost, so they just lay the sewage treatment plant
there, only operating when the investigation team came. In 2005, the central government ofChina issued a regulation, orders all the cities must collect the sewage treatment fee, graduallyraises it, till covers the running cost and the property depletion.
Weihai is the pioneer of sewage treatment fee collection. In 2000, the Weihai government
issued a regulation to collect a sewage treatment fee from beneficiaries, 0.40 yuan/t forenterprises, and 0.20 yuan/t for residents. In 2006, we raised the treatment fee to 0.8 yuan/t
for resident, 1.1 yuan/t for factories. Now the sewage treatment cost in Weihai is about 0.9
yuan/t. In this case, the sewage treatment fee collected can almost balance the cost.
-189-

The collection rate of the sewage treatment fee is another problem. In some cities theresidents and factories refuse to pay the sewage treatment fee, they argue the amount they
discharged, because usually there is no meter for the sewage, and in most of the cities the
responsibility of water supply and drainage are belong to different government departments, it
is difficult for the drainage staff to prove it. In order to improve the water management
efficiency, in August 2003, Weihai reformed water management system, established Weihai
Water Affairs Group. Weihai municipal government gives all the responsibility and power forboth the water supply and drainage to this group. Now the responsibility is clear and the work
efficiency is higher. The Water Group collect wastewater treatment fee with the water supply
fee together, if no special reason, from how much water consumed, they can calculate howmuch sewage have discharged. If somebody refuses to pay the sewage treatment fee, hecannot get the running water. So the sewage treatment fee collection rate is almost 100%.
Using market mechanism, encourage new water resource exploration
In Weihai urban area, the population and industry have developed very fast, and this trend willcontinue for some time. Water shortage is a strategic bottleneck for the development of
Weihai. Water saving alone cannot solve the problem in long term. We must explore newwater resources to meet the demand of development.
Before the initiative takes place, because the running water price was low, the other water
alternative resources can not compete with it, so the factories have no motivation to explore
new water resources. After the initiative, the running water price for industrial usage has beenraised from 4.00 yuan to 6.85 yuan, that give the chance for water alternatives.
Weihai is a coastal city; we have 986 km of coastline, the longest of any city in China.
Desalination is one of the alternatives. Before 1999, we only use seawater for industrial
cooling. There were no desalination stations because the cost is higher. But during the 19992000 drought, the water means survival or death for some factories, and after the runningwater price raise and the desalination technology improvement, the cost of the desalination
almost can compete with the running water, desalination stations began emerging.
The first desalination station in Weihai was constructed by Huaneng Weihai Power Station in
2001. This power station is the biggest water consumer in Weihai. During the drought season,
it faces high pressure, which led them to find an alternative in constructing a desalination
station. The capacity is 2500 tons per day, the investment was 18 million yuan RMB, and therunning cost is about 7 yuan RMB per ton. The second desalination station was constructed in
2002; it was built by the Weihai Water Affaires Group. This station is constructed on an island,
to solve the drinking water problem of the residents on the island. Its capacity is 500 tons perday; total investment is 8 million yuan RMB. The third desalination station was constructed in2003 by a fishing company, to solve the water shortage problem for the nearby area. Its
capacity is 5000 tons per day, total investment is 40 million RMB.
Another alternative is reuse treated wastewater. Now we have three sewage treatment plants
in the central city. Most of the treated wastewater is discharged into sea directly. This is awaste. In 2003, the Weihai Water Affairs Group constructed a water purification plant, using athird treatment method, deeper treat the water discharged from the second treatment plant,
makes it meets the standard for most of washing, irrigation, cooling and engineering. The
capacity is 10,000 tons per day, and investment is 30 million RMB. They sale the treated-190-wastewater at 1.00 yuan per ton, that much cheap than the running water, so most tree andglass land irrigation use this water, some factories use it for cooling and washing, some office
and residents buildings use it for toilet flushing.
In recent years, some cities try to store rainwater for industrial and municipal usage. That is a
new idea for us. We began to do some investigation and feasibility study in this area.
Strength environment education
In order to stress the public participation in water management, we pay much attention on
environmental education. We set up an environmental program on TV and radio; a column inthe newspaper Weihai Daily; publishes environmental information, environmental law andgood practices. We disclose the environmental information, established a website,www.whep.gov.cn, where the public can get the environmental regulations, standards,
statistics and environmental qualities. We opened the mayor’s mailbox, mayor’s hotline 12345,
and environmental hotline 12369, to answer questions and receive complaints about theenvironment. Whenever we want increase the water price, we held a public hearing, consult
with the public, collect their opinions, after reach a general agreement, then make the decision.
Housewives are the important players in thewater environment management. We
encouraged local communities to organize
housewives to participate in various
environmental activities, to share theirexperience on water saving, visit thereservoir and sewage treatment plants andincrease their awareness of the water
environment.
ImpactSince the initiative of water environment management began, the effect is obvious. In 2007,
compared with 1999, the supplied water increased from 43.67 million tons to 63.30 million
tons; the industrial water reuse rate increase from 89.62% to 93.14%; the sewage treatment
rate increased from 59.99% to 83.56 %. Though the urban population and GDP grew very
rapidly as mentioned, but the water environment remains good quality. All the rivers, the sea
water, the supply water resources can meet the national standard.
Weihai received the awards of 1st National Sanitary City, National Model Cities forEnvironmental Protection, National Garden City, and National Excellent Tourist City. Weihai
has twice got the International Award as the Best Practice for Comprehensive Management of
the Living Environment by UN-HABITAT in 1996 and 2000; got the UN-Habitat Scroll of
Honor Award in 2003; got the name of Eco-City from the National Environmental
Administration of China in 2006.
Replicability
Most of the cities in China face the same problems as Weihai, water shortage, environment
pollution and lack funds. The initiative in Weihai is the pioneer in China, the experience in
Weihai is a very good show case for other cities. After the No.3 Sewage Treatment Plant BOT
project completed in October 2006, until now, there are 90 delegates, 300 visitors come fromother cities visited the plant. Experts from UN ESCAP and IGES are also interested in-191-Weihai’s experience, try to organize a study tour in Weihai, let other cities in Asia and Pacificregion to share the experience in Weihai.
Lessons Learned
There are some issues that still need to be improved in the water environment management in
Weihai, mainly are:
The pollutants discharge fee. China created the regulation for pollutants discharge feecollection in 1982, emended the regulation two times later, increased the fee rate and scope.
The pollutants discharge fee is a good mechanism, that encourage the company to save theresources, decrease the pollution. But now the rate of the fee is a little bit low, in some cases
can not cover the damage it caused; and the enforcement of the regulation is weak. So weneed to increase the fee rate and scope again and stress the enforcement, let it has thepunishment effection.
Public participation. Public participation in environmental protection in China is justbeginning. Though the item has appeared in some environmental laws and regulations, only a
few are in practice. Public participation in water environment management in Weihai still in a
primary stage, they still lack the knowledge, the information, and especially organization.
Using the market mechanism. Several years ago, all the cost for the water environment
management came from the government revenue, these years we introduced the market
mechanism into this area, but we are still in the early stage and lack experience. BOT is agood option to cover the needed investment. But there is no law to follow until now in China.
If there are some disputes, it will be difficult to solve them.

Abstract
The Philippine Clean Water Act (CWA) of 2004 specifies the designation of certain areas as
Water Quality Management Areas (WQMA) using appropriate physiographic units such as
watershed, river basins or water resources regions. The WQMA shall have similarhydrological, hydrogeological, meteorological or geographical conditions which affect thephysico-chemical, biological and bacteriological reactions and diffusion of pollutants in thewater bodies or otherwise share a common interest or such as similar development programs,
prospects, or problems. Each WQMA will have a Governing Board, a Technical Secretariat
and a Water Quality Multi-sectoral Group to carry out planning and implementation activities.
The designation of WQMA is one of the strategies identified to effectively enforce the CWA
and improve the water quality of water bodies through focused interventions or actions thatare designed to address specific water quality issues of the areas. Therefore, the designationof WQMA shall take into consideration water quality problems, its sources of pollution, andthe beneficial use of the receiving water body; and shall determine what combination ofcontrol measures can effectively achieve water quality objectives or improvements.
To date, officially designated WQMA are the area within the jurisdiction of the Laguna Lake
Development Authority, the Tigum-Aganan Watershed WQMA, and the MarilaoMeycauayan-Obando River System WQMA. Activities for the designation of Iloilo-BatianoRiver System WQMA in and Sarangani Bay WQMA are on-going.

Introduction
Republic Act (RA) No. 9275 or the Philippine Clean Water Act (CWA) of 2004 is the basic
law on water quality management in the Philippines. CWA was published on 21 April 2004
and subsequently took effect on 6 May 2004. The Implementing Rules and Regulations (IRR)of CWA was approved as Department of Environment and Natural Resources (DENR)
Administrative Order No. 2005-10.
In Article 1, Section 2 of RA 9275, the policy of the CWA is stated as follows: “The State
shall pursue a policy of economic growth in a manner consistent with the protection,
preservation and revival of fresh, brackish and marine waters” using the framework ofsustainable development. Section 3 of the CWA further states that water quality management
shall primarily apply to the abatement and control of pollution from land-based sources.
-193-

The water quality management areas (WQMAs) are designated as part of the water quality
management system as provided in the entire Chapter 2 of the CWA. Water Quality
Management Areas are certain areas using appropriate physiographic unit, such as watersheds,
river basins or water resource regions. These management areas shall have similarhydrological, hydrogeological, meteorological or geographical conditions which affect thephysico-chemical, biological and bacteriological reactions and diffusion of pollutants in thewater bodies or otherwise share a common interest or such as similar development programs,
prospects, or problems. Each WQMA shall have a Governing Board (GB) which shallprimarily serve as the planning, monitoring, and coordinating body of the said WQMA. The
GB shall also review the WQMA Action Plan prepared by the DENR through the EMB. A
Technical Secretariat and a Multi-sectoral Group for water quality monitoring andsurveillance shall also be provided to the WQMA.
The designation of WQMA is one of the strategies identified to effectively enforce the CWA
and improve the water quality of water bodies through focused interventions or actions thatare designed to address specific water quality issues of the areas. Therefore, the designationof WQMA shall take into consideration water quality problems, its sources of pollution, andthe beneficial use of the receiving water body; and shall determine what combination ofcontrol measures can effectively achieve water quality objectives or improvements.
Guidelines for the designation of water quality management areas
The policy of the DENR is to develop a holistic national program of water quality
management through the designation of WQMA, the identification of non-attainment andattainment areas, and the preparation and implementation of WQMA Action Plans to improvewater quality of water bodies. This should be achieved within the integrated water resource
management (IWRM) framework and implemented through the proper delegation andeffective coordination of functions and activities.
The Guidelines for the Designation of Water Quality Management Areas was developed withthe following objectives:
1. To provide the process through which a WQMA is delineated and designated.
2. To provide useful information for use by the EMB, the Local Government Units(LGUs) and other stakeholders that would ensure that the process of designation of
WQMAs is done uniformly.
3. To explain the technical requirements and participatory approaches to direct theusers in effectively initiating/implementing the designation of WQMAs.
A WQMA will consist of surface waters, whether natural or man-made and include streams(rivers and creeks), lakes, and marine waters. Only the water bodies that have been classified
by the DENR through the EMB based on its beneficial use will be included in considering
WQMA designations. A WQMA will also cover the land that is within the hydrologic unit
identified, including residential, industrial, commercial, agricultural, tourism, forest andprotection areas.
A.

Conditions in Designating a Water Quality Management Area
There are four major conditions that must be present when a WQMA is designated.
These are:-194-

1) The WQMA shall utilize an appropriate physiographic unit, such as a watershed,river basin, or water resource region. However, the use of the lowest appropriate
level (such as the sub-basin or micro-watershed) is deemed more suitable from thestandpoint of ecological, financial, organizational and institutional considerations.
2) The WQMA shall have similar hydrological, hydrogeological, meteorologicalor geographic conditions which affect the physicochemical, biological andbacteriological reactions and diffusions of pollutants in the water bodies.
3) The WQMA shall share a defined common interest, such as, but not limited to,similar water quality-related development programs, prospects, or problems.
4) The water quality of specific water body/ies within the physiographic unit
chosen may be:i) A non-attainment area (NAA) that needs immediate water quality management
interventions to improve the water quality. This a body of water in which thelevel of a criteria water pollutant is higher than the level allowed for its
classification under the water quality guidelines.
ii)
A combination of NAA and Attainment Area (AA). AA is a body ofwater that has acceptable levels of water pollutants and therefore meets the water
quality guidelines. The designation of a WQMA with a NAA and an AA isapplicable when there is a need to improve water quality and the management of
the existing and potential pollution sources must be addressed through specificinterventions.
iii)
An AA, but water quality management interventions are needed to
improve and/or preserve its condition.
Even if the WQMA without a NAA is justified given the above conditions,priority should be given to the areas where water quality has already exceeded
the water quality guidelines to ensure that limited resources is efficiently used.
The screening of a WQMA proposal therefore, may be made according to theintensity of the pollution problems and its impacts on public health and on theregional economy.
B.

Process of Designation
There are two ways by which a WQMA may be initiated. The first way is throughthe DENR RO, as specified in Section 5 of the CWA, and Rule 5.1.1 states:“Initiating the process of designation. The Regional Office of the Department
shall initiate the process of designation by evaluating information using the criteria
to be developed by the Department.”
The second way is proposing the designation of a WQMA from other sources or
proponents aside from the DENR RO through the EMB RO. Rule 5.1.1 states:“Initiating the process of designation. . . . However, any concerned government
agency, including local government units, Protected Area Management Boards,
watershed councils, Fisheries and Aquatic Resources Management Councils,
government corporations with relevant concerns, or civil society, may propose thedesignation of WQMA in their area to the DENR and submit the relevant
information. The concerned agency or organization shall follow the generalprocedure for designation outlined herein and coordinate with the Department
throughout the process of consultations and data gathering.”-195-

In any case, whether or not the process to designate a WQMA is by the EMB orother proponents, the designation process will pass ten (10) main steps, as shown in
Figure 1. Procedure for Designation and Re-designation of WQMA. These steps
establish a consistent way to designate and re-designate WQMA, while still
maintaining the flexibility to accommodate the distinctiveness of each WQMA.
The EMB Regional Office (RO) shall be the lead agency for this activity.

Figure 1. Procedure for Designation and Redesignation of WQMA
-196-

1. Gather Relevant Data/Information
Among the relevant data/information that should be collected include maps; major threats
to water quality, sources of pollution and other related data; common interest such as
water quality-related development programs and prospects in the areas to be covered by
the proposed WQMA; stakeholders’ Support; and socio-economic data.
2. Evaluate the Data and Information
The data and information gathered must be evaluated against a set of criteria to ensure thatthe data is adequate to designate a WQMA.
3. Coordinate with the National Water Resources Board
In designating a WQMA, the Department will coordinate with the National Water
Resources Board (NWRB).
4. Convene Key Stakeholders
Key stakeholders will be identified afterwhich information dissemination and consultation
activities will follow.
5. Conduct Public Consultations
Not only the key stakeholders are to be informed and consulted on the proposal todesignate a WQMA, but also the general public. Public consultations provide an
opportunity to inform, educate and communicate with an identified or targeted public.
6. Evaluate Proposal by the EMB Central Office
The proposal to designate a WQMA must pass evaluation by the EMB Central Office(CO), in particular, its Water Quality Management Section. If found to have fullycomplied with the law, then the proposal will be forwarded to the Office of the
Department Secretary with the recommendation for WQMA designation, based on having
met the prerequisites for designation such as the completion of all data requirements, andthe conduct of key stakeholders and public consultations. However, if the proposal isfound to have not fully complied with the requirements, then it shall be returned back to
the EMB RO, with notations.
7. Recommend WQMA Designation and Composition of the GB to the Department
Secretary
All final recommendations for WQMA designation and composition of the GB are
addressed to the Department Secretary, and shall emanate only from the Director, EMB
CO. This ensures that each proposal has passed strict evaluation for its compliance withall the requirements found in the CWA.
8. Designate WQMA by the DENR Secretary
Rule 5.1.7 of the CWA IRR states that the designation of the WQMA is made by the
DENR Secretary upon the recommendation of the EMB. The designation, therefore, shalltake the form of a Department Administrative Order (DAO).
9. Inform the LGUs, NGAs, Business, Civil Society/NGOs, GOCCs and Water Utility
Sectors to Submit Nominations in the GB
The main provision on the designation of the WQMA GB is found in Section 5 of the
CWA, which states:“. . . Said management area shall be governed by a governing board composedof representatives of mayors and governors of member LGUs, andrepresentatives of relevant national government agencies, duly registerednongovernmental organization, water utility sector, and business sector. The
Department representative shall chair the Governing Board. In the case of the
LGUs with membership on more than one (1) management board, the LGU-197-

shall designate only one (1) single representative for all the management areas
where it is a member.”
10. Submit Names of GB Membership to the DENR
The names of the permanent and alternate members of the GB shall be submitted to theSecretary of the DENR for approval.
11. Re-designate WQMA
The re-designation of a WQMA can be undertaken as stated in Rule 5.1.7 of the IRR
CWA:“Thereafter, these initial WQMA may be subject to review and consultations
for re-adjustment of boundaries and representation in the Governing Board, if
necessary.”
Designation of water quality management areas and creation of the governing board
Per Section 5 of RA 9275, the area within the jurisdiction of the Laguna Lake Development
Authority (LLDA) was designated as one WQMA under the administration of the LLDA.
Aside from the Laguna Lake WQMA, there are two officially designated WQMA, namely,
the Tigum-Aganan Watershed WQMA in Iloilo province (Region VI) and the MarilaoMeycauayan-Obando (MMO) River System WQMA in Bulacan province (Region III)through DENR Administrative Orders (DAO) Nos. 2006-18 and 2008-07, respectively. The
DAO also created the Governing Board for the said WQMA. Activities for the designation of
Iloilo-Batiano River System WQMA in Region VI and Sarangani Bay WQMA in Region XII
are on-going.
The following section will focus on the designation of the Marilao-Meycauayan-Obando
River System as a Water Quality Management Area.
The MMO River System WQMA is within the province of Bulacan in Region III and parts of
the National Capital Region. The area is at the southern end of the Central Valley Basin where
major rivers (including Pampanga, Angat, and MMO Rivers) flow from the north and eastthat eventually drain into Manila Bay.
The MMO River System was prioritized for the WQMA designation due to the following
issues:1.

2.
3.

MMO River System is one of the priority rivers for rehabilitation by the EMBDENR. There is an immediate need for water quality management
interventions to revive the Marilao-Meycauayan-Obando River Systems. Thisis due to various sources of pollution such as domestic wastewater, industrial
effluent, dumpsite leachate, agricultural run-off upstream, and nutrient buildup due to aquaculture downstream.
The MMO River Systems has an active group of NGOs fully supported by the
LGUs, concerned NGAs, and the private sector.
Water quality monitoring data is available.

Identification and evaluation of candidate sites
Identification of water quality problems and possible actions to address the
problems
Verification of water classification and use of the proposed WQMA
Gathering of relevant primary and secondary data
Evaluation of data for boundary setting
Convening of the key stakeholders
Conduct of public consultations

The Governing Board (GB) for the MMO River System WQMA is being chaired and cochaired by the Environmental Management Bureau Regional Directors of DENR Region III
and NCR, respectively. Members include representatives from the LGUs in Bulacan,
Valenzuela, and Caloocan; relevant national government agencies; Laguna Lake
Development Authority; business/industry; water utility; non-governmental organizations;and the academe. The composition of the GB is in line with the policy of the Philippine Clean
Water of 2004 which encourages the participation of an informed and active public in water
quality management.
The “success” of the MMO River System WQMA lies in the preparation and implementationof the Water Quality Management Action Plan through multi-stakeholders participation.

Abstract
Integrated Water Resource Management (IWRM) principles, where the need of holistic andsystematic management approach is required, has been accepted by the Malaysian
Government and these needs are already in the government policy statements such as in the
RM8, RM9, OPP3 and the National Water Vission.
The Federal Government has encouraged all state governments to establish its own water
management system i.e. in complying with the standard IWRM policies. The state of Kedahand Sabah has recently gazette their own water management act. The Selangor State
Government has already established the Lembaga Urus Air Selangor (River BasinManagement Authority) Enactment way back in 1999 to improve their river basins
management.
One of the river basins in Selangor which need a serious and systematic approach ofmanagement is the Putrajaya Lake Catchment. The planning, approval, monitoring andenforcement jurisdiction over all land development and human activities in this catchment
area will have a direct impact to the Putrajaya Lake. The Lake is an urban lake, created rightin the middle of the newly developed Putrajaya, the Government Administrative City of
Malaysia.
Putrajaya was planned to be developed into a “City in a Garden” with the 600 hectares
Putrajaya Lake and Wetland as its focal point. The lake has to be always in acceptable urban
setting condition with a high water quality level to cater its multi-functional uses such as forboating, fishing, recreational and water sport.
This paper discusses the Putrajaya Lake Catchment system and the various mechanisms that
had been implemented for an effective and best result to ensure the high water quality level ofthe lake is continuously maintained. It also describes some problems in implementing aneffective catchment management.
Keywords: Catchment management, Putrajaya lake and wetlands, management issues,
implementation, enforcement, monitoring and funding.
Introduction
The Malaysian Government in its policy statements and other planning documents has
included the Integrated Water Resource Management (IWRM) approach as part of its
development programs. This holistic water management approach is already in thegovernment policy statements such as in the RM8, RM9, OPP3 and the National Water
Vision.
-200-

All the State Governments had been encouraged to establish their own water management
system that complies with the standard IWRM policies. The states of Kedah and Sabah havegazetted their own water management act for this purpose. The Selangor State Government
had gazetted the Lembaga Urus Air Selangor (River Basin Management Authority)
Enactment in 1999 to improve its river basins management.
The Putrajaya Lake Catchment and LUAS
One of the river basins in Selangor which need a serious and systematic management
approach and control is the Putrajaya Lake Catchment.

Figure 1. The Putrajaya Lake Catchment is only a small part of the bigger Sungai Langat
River Basin.
The Putrajaya Lake Catchment is a small river catchment of about 52.4km2(squarekilometers), located in the middle of Sungai Langat River Basin, 25 km south of Kuala
Lumpur. It extends about 12 kilometers in the north to south direction and about 4.5 km in theeast to west direction.
Figure 1 shows the location of this small catchment within the large Sungai Langat River
Basin. In this small catchment area lies the Putrajaya City – the newly developed Government
Administrative Center of Malaysia. The 600 hectares Putrajaya Lake is the focal point of this“City in a Garden”. The lake is use for activities such as recreational, boating, fishing andwater sport, in addition to enhancing the aesthetics of its waterfront characters.
Even though it is an urban lake in the middle of a city, the Putrajaya Lake has always to be in
its acceptable good water quality conditions to cater for its multi-functional uses.
As an urban lake with active human activities around it, the planning, approval, monitoringand enforcement jurisdiction over all land development and human activities in its catchment
will have a real and direct (normally negative) impact to the water quality and the lakecharacteristics.

Development projects within Putrajaya boundary, which occupies about 60% of the Lake
catchment area are complying to the Putrajaya Masterplan and stringent regulatory enforcedby the Perbadanan Putrajaya (PPj).
However, the remaining 30% of the same catchment area but located in the upstream partoutside the Putrajaya boundaries (in the state of Selangor as in Figure 2) belongs to various
landowners and without coordinated control over its development and acitivities programs.
This has become a serious concern to the Selangor State Government as well as to the
Perbadanan Putrajaya.

The Putrajaya Lake integrated catchment management
Why is it important to manage the catchment?
Being a man-made lake in an urban setting, the Government recognizes that careful planningand management of the physical as well as the human issues within the catchment isnecessary.
The task is to achieve and maintain The Putrajaya Lake Ambient Water Quality Standards(PLWQS) (which is of higher level than the DOE’s Interim Water Quality Standards of Class
IIB) and other objectives set for Putrajaya Lake and the allowable activities in it.
One of the major issues is the control of development activities in the catchment. There is aneed to develop a pragmatic and implementable plan of action to ensure that the catchment
area of Putrajaya Lake and the water resources within the catchment area are protected from
pollution and the water quantity is maintained.
Furthermore, the design objectives of the artificial wetlands were only to improve the water
quality of the surface runoffs flowing into the lake from the upstream areas. It was designed
to treat only certain level of pollution loading i.e. the level of pollutant in the runoff should be
limited to a certain acceptable level to enable the wetlands to function properly.
In the year 2000, Perbadanan Putrajaya has developed the Catchment Development andManagement Plan (CDMP 2000) for Putrajaya Lake Catchment. This document is for easy
reference to all stakeholders and it provides guidelines on the various methods/control toachieve and maintain the water quality level required for the Putrajaya Lake. The guidelines
also define the land-use, drainage and sewerage master plans for the areas within the small butvery important catchment.
Lembaga Urus Air Selangor (LUAS)
The CDMP 2000 has clearly defined the role of LUAS in implementing its power to manage,
control and enforce the necessary rules to the landowners and stakeholders within the 30% of
the Putrajaya Lake Catchment area in Selangor.
During the last eight (8) years of applying the CMDP 2000 guidelines, however, shows thatthe planning control for land use, drainage, environmental pollution control and coordination
tasks empowered to LUAS is not easily applicable and implemented by the agency.
At the same time, realizing its role to ensure the success implementation of the IWRM and
IRBM in the state, a strategic empowerment review of this organization is necessary to arrest
various setbacks experience so far.
Thus, the challenges face by LUAS can be defined which includes the following:••••

The problems are known;
The causes are often complex and the problems cannot be solved overnight;
The main task will include the decision on how to implement a successful
coordination and programs agreeable by all stakeholders; andThe Putrajaya Lake Catchment is the testing ground of its capabilities to apply the
IWRM principles to all other areas in Selangor.

Catchment Management Plan Policy Statement
Recognizing the importance of careful planning and management control for the attainment of
the city vision, Putrajaya Lake Catchment Management Plan need to be based upon thefollowing policies:
i.

iv.
v.
vi.
vii.
viii.
ix.

Pollution control measure shall focus on the minimizations of pollutant generation atsource;The drainage system shall base on vegetated landscape drainage corridors andconversion of flood detention and water quality enhancement ponds into miniwetlands;
The Putrajaya Wetland will be considered as an additional (last stage) water quality
enhancement or “polishing” mechanism. It will integrate with the upstream water
quality enhancement features, such as vegetated landscape riparian buffers, drainage
corridors and upstream mini-wetlands cum flood detention ponds.
Diversion or alteration of the natural drainage lines in the catchment shall not beallowed, however, improvement of its flow profile will be considered;All development activities in the catchment shall be in accordance with an agreeable
and approved Catchment Development Land-use Master Plan.
All pertinent regulatory agencies shall coordinate (LUAS will play major role) theirfunctions and enforcement effort to attain the catchment management objectives andtargets;
Active participation of the catchment stakeholders and communities in the
management of Putrajaya Lake;
Equitable sharing of the cost for the implementation of the catchment management
programs including the maintenance cost shall be recovered based on the policyof ”the polluter pay” and “the direct beneficiaries pay”.
Realization of that, the cooperation and mutual agreement among all stakeholders inachieving the common goal of best water quality level of the surface runoff flowing
through a catchment will be the best Integrated Water Resource Management outcome.

The successful implementation of ICDMPThere is a need to update the CDMP 2000 to incorporate eight (8) years of implementation
experience and taking into consideration the latest policy, legal, current and future landuse
plans of the catchment stakeholders. This will include the identification of the relevant clausesin the LUAS Enactment and develop the required institutional framework to enable LUAS towork with Perbadanan Putrajaya to protect Putrajaya Lake Catchment.
The Review Strategy
i. Development of institutional structure and identification of necessary legal provisions
in LUAS Enactment to enable management of the 30% of the Putrajaya Lake
Catchment, which is in Selangor, to be upgraded to the same level as that implemented
by Perbadanan Putrajaya;
ii. Proposed institutional structure for managing the Putrajaya Lake Catchment, utilizing
the provision in the LUAS Enactment (e.g. Clause 56 that is to enable the Putrajaya
Lake Catchment to be a “Declared Catchment” with a management body involving all
pertinent stakeholders);

Legal guidelines to support LUAS and Perbadanan Putrajaya in implementing atransboundary catchment institutional framework, utilizing the existing provisions in
the LUAS Enactment, and other related laws;
Updating of CDMP 2000, so that an integrated lake catchment management andmonitoring system can be implemented by the developed institutional structure
especially by LUAS and its legal provisions; andInfo-sharing among catchment’s stakeholders to support Integrated Catchment
Management System (ICMS)
Effective telemetry system to enable real-time, remote measurement and reporting oflake catchment monitoring information centre.

Aspects of Management and Planning
The CDMP 2000 review will cover the details for the integrated regulatory control for theareas outside Putrajaya especially on the following aspects:a) Planning and Land-use Control;b) Drainage Planning and Water Quantity Management;c) Sewerage Planning;d) Environmental Management and Water Quality;e) The Lake and Wetlands;f) The information System study; andg) Legal and Coordination Between Regulatory Agencies
The management scopes and its recommendations for review on various aspects are as inAppendix A.

Implementation requirements
i. Successful implementation requires co-ordination, co-operation and collaboration
between existing planning authorities and between different interest groups andstakeholders.
ii. CDMP is more than a technical and engineering solution to catchment management,
providing a platform for integration of various stakeholders’ interest, besides
establishing an overall guidance for consistent implementation of policies.
iii. Legislative and institutional framework has to be put in place first to establish thediscipline and direction.
iv. It is necessary to establish a mechanism that can merge co-ordination and seek cooperation not only across sectors, but also political and administrative borders.
The Catchment Development and Management Committee
In keeping up with the catchment development on-going progresses, cooperation andcoordination amongst the stakeholders together with the implementation of various
regulations and control of land development and human activities, A Federal and State intergovernment committee consisting of officers from different government agencies, local
authorities and stakeholders will need to be established.
Known as the Putrajaya Lake Catchment Management Committee (PLCMC) as
recommended by the CDMP 2000, the formation of this committee will be in accordance to
the Selangor Waters Management Authority Enactment (SWMAE, 1999).
The earlier recommended committee chaired by the State Secretary of Selangor (as listed inAppendix B) with Lembaga Urus Air Selangor (LUAS) and Bahagian Tasik Perbadanan
Putrajaya as the joint-secretariat, however, has no legal powers. Thus, to facilitate themonitoring and implementation of legislative enforcement of the catchment area, a legallyconstituted Management Committee is to be formed under the SWMAE (1999).

-206-

To expedite the legal process in implementing, monitoring and enforcement of the SWMAE(1999) Act, Perbadanan Putrajaya and the Selangor State Government through LUAS is
preparing the formulation of the “Study on Operationalisation of LUAS’s 1999 Enactment for
Institutional Development and Integrated Catchment Management for Putrajaya, 2008”

Conclusion
The success of the implementation of an Integrated Catchment Management especially for an
urban catchment depends largely on the cooperation and coordination between thestakeholders (landowners), government agencies and the local authorities involved.
Although through the cooperation of LUAS, MPSJ, MDS and Perbadanan Putrajaya, theexisting by-laws and guidelines can be executed within the CMDP, the real challenge iswhether the authorities can work together with all the landowners and stakeholders for acommand goals of achieving a predetermined water quality of a lake.
The success, however, will be seen more effectively whereby the by-laws and guidelines iscarried out by all the stakeholders of the lake catchment voluntarily for the benefit ofeverybody within the catchment.
The practical application of this arrangement will also be a showcase of our legislative
frameworks and the much-awaited effective solutions for the use of all the other water basins
management for the whole of Malaysia.

Appemdix A: Catchment Management Scope Review and Recommendations
SCOPE

DESCRIPTIONRECOMMENDATION

Water Quality
Management

The current water quality in the lake is
within the permissible values of Putrajaya
Lake Water Quality. It is recognized that themost effective way to attain the desired water
quality objective is to minimize thegeneration of pollutants at their source. Also,
it is recognized that erosion and transport of
sediment during the land clearing,
earthworks and construction phase pose avery serious threat to lake water quality.

Water Quantity
Management

It is important that all possible runoff arisingfrom lake catchment should enter into theLake system. Also, there should be proper
control over the amount of water drawn for
irrigation or other purposes and no diversion
or alteration of the natural drainage lines in
the catchment is to be allowed.

To manage pollutants at source.
The drainage system should be based on vegetated landscaperiparian buffers, drainage corridors and mini-wetlands water
quality enhancement ponds.
To prevent the entry of rubbish
Gross pollutant/sediment trap (GPT) structures are to beinstalled at the ends of all concrete drains flowing into thevegetated landscape drainage corridors.
To ensure effective control of erosion and sediment during
earthworks.
It is recommended that a new “Erosion And Sediment Control
By Law” be enacted by Putrajaya Corporation and Majlis
Daerah Sepang. The recommended By- Law should be
supported by a new “Standards For Erosion And SedimentControl” Manual.
Compensation flow equal to 10% of the Annual Average Flow
may be allowed during the in-filling of the main dam.
A well field of 6 groundwater wells can be developed,
downstream of the main dam, to supply 0.013 m3/s (10,000g/hr) of groundwater to meet any water demand.
A separate irrigation masterplan study on the impact of the
proposed rainwater harvesting within the catchment on thewater quantity in the lake

Pollutant Sources
Management

The sewage effluent discharge from outside
have been identified as the major point
source pollutant. They are controlled in thesewerage masterplan.
Accident associated with the oil tankers
moving along the road passing through thewetlands can be a major point source
pollutant. Thus, the pertinent authorities(JKR, Putrajaya Corporation) has to ensurethat Emergency.
Response Plans and Procedure are preparedand implemented to handle such potential
emergencies.

Non-point pollutant sources from road runoffs are to becontrolled through the implementation of the drainage system
based on vegetated drainage corridor. Those from fertiliser andpesticide input from MARDI, UPM, IOI, and Cyberjaya are to
be controlled by regulatory measures using the prepared MP
guidelines on the use of fertilizer and pesticides.

Abstract
Promoting local initiatives in participatory environmental governance to improve water
quality would ensure more effective success and sustainable. The problem within local
initiative in Indonesia, however, is that poor who should become active actors in theirdevelopment are often beyond easy reach. Within the Indonesian decentralization policy withsuch ambiguities, the participatory process has descended into an arena for predatory politics.
It is about the credibility of elites and governments with such temptation to weaken, delegitimize, incorporate or indeed repress social movements. If that so, the papers will takeadvantage of the possibility for a critical perspective afforded by some community
development programs at helping communities to attain the right to clean water as poverty
reduction strategies in the shaping of specific developmental intervention by donor. In
particular, a primary role is played by processes of “collective learning” which result in a“socialized” growth of knowledge and embedded not only in the internal culture of local
community but, particularly, for the private sectors. Pilot testing the use of a participatory
assessment in Surabaya is designed to promote specific measures of design andimplementation that take better account of participation, community demand, gender, andpoverty perspectives.
Keywords: participatory environment governance, water quality, collective learning
Introduction
The best way for development agency to facilitate local initiative is just not to focus on
capturing, codifying, and documenting knowledge of individuals, but rather to concentrate on
ways, through which knowledge can be shared, discussed and innovated (Smith 2003;
Mittendorff, 2006). It needs to generate a shared repertoire of ideas, commitments, andmemories which in line with developing of various resources such as tools, documents,
routines, vocabulary and symbols. Along with social network, a development agency will also
contribute to attune their values with their stakeholders, clarify their social responsibilities,
develop new local knowledge and innovative solution to overcome problems, enhance mutual
understanding and built the trust and commitment necessary for collaborative action(Svendsen and Laberge, 2005). However, Bebbington (2006) raised question to the credibilityof elites and governments with such temptation to weaken, de-legitimize, incorporate orindeed repress social movements. For external actors, i.e. community or non-governmentorganization, such governments can become the object of policy which the process can be-211-fraught with tensions both within government as well as in its relationships with other sectorsof society.
Following the Indonesian decentralization policy, local initiative has been emerging as acentral issue for adaptive co-management, particularly in order to fulfill the basic right onclean water. Many programs for community water, such as irrigation management reform
program, water resources and irrigation sector management program or green and clean
competition emphasize a participatory approach to the management in a decentralizedadministrative and fiscal framework. Through Act no 25/2004, it is a mandate to both national
and local government to conduct development planning which aims to maximize citizen
participation”. For the biggest archipelago country with 50% of 215 million populations
living within $2 per day income per capita, the task of involving poor people in the planningand implementation of development efforts has to deal with contests between competinginterest. Involving community in developing program seems to be threats for those who havebeen having privilege on local resource. Some others view participation with deep skepticism
and argue that communities prefer to do simply argue within development to get some morefinancial support rather than focus on the long term goal. With some legal contradictions andambiguities, the participatory process has descended into an arena for predatory politics. If
that so, the question comes up to what the best way to motivate all community members toshare repertoire of ideas and build commitments.
The papers would like to share the best practices about community development program forthe types of water issues we encounter in Surabaya inner-city environments. It generates thequestion on what type of learning result on how the program responds to particular water
issues in the urban context and what the particular challenges faced in translating community
development into social-ecological change within today's urban setting. To investigate thesequestions, we describe a recent participatory assessment in some local initiatives in City ofSurabaya Indonesia which concern on improving water quality. The research leads to somelessons for practitioners, such as the need to build "constant" elements into community
development projects.
The Legacy of Local Initiative
Basically, the local initiative to environment improvement has been a common activity for allcommunities in Indonesia, particularly as part of activity to celebrate the independent day.
Started at early August, the citizens conduct a communal work of cleaning the vicinity of theirhouse and environment. This spontaneous work is called “kerja bakti”. Kerja means work,whereas bakti means devotion. They do it in a “gotong royong” way, which means work handin hand with each other to dress up their kampong, clean up the disposal of waste water, andfor rapid run-off of rainwater. During the economic downturns in 1998, the activity on doing
garbage collector has also become local economy activities in Surabaya in which more poor
people took a job to waste picking as a survival strategy. One of the most popular jobs ismetal waste picker, which common to Madurese ethnic who living in northern part ofSurabaya City. While poor and inaccessible areas are plagued by pollution from uncollected
wastes, many inhabitants of these areas depend upon waste recovery and recycling to meetsome of their basic needs for shelter, food and employment.
Responding to the economic crisis in 1997, a community development program began in
Kampong Rungkut Lor in 1999 initiated by PUSDAKOTA. At the early stage, the-212-development organization would like to address the source of poverty, particularly
unemployment through job creation for communities who lost their jobs during the crisis.
Instead of adopting high class professor, the program was involving some young social
workers who easily live up with community within poverty condition. The community
development workers were envisaged as a "helper", "encourager" and "facilitator". Focusing
on capturing, codifying, and documenting knowledge of individuals for two years, theorganization came up with conclusion that the main problem in Rungkut Lor was not
economic issue but environment, such as flood, sanitation, health, and waste due to poor
water quality. What need to be done was not offering the community with such bulk offinancial resources and making them hope the financial support. If that so the program
initiated with strong effort on doing informally integrated between communities and the social
worker to generate a shared repertoire of ideas, commitments, and memories which in linewith developing of various resources such as tools, documents, routines, vocabulary andsymbols. As González et al, 2007 pointed out, there is a growing consensus that the best way
to improve community learning is not to (simply) focus on capturing, codifying anddocumenting knowledge of individuals, but rather to concentrate on ways through whichknowledge can be shared, discussed and innovated.
Started at the end of 2001, Pusdakota organized a community in Kampong Rungkut Lor toseparate the communities' household waste. Struggling with local commitment building, they
were request to separate between organic and inorganic waste from their own houses. These
projects have come to incorporate source segregation of wet and dry wastes and thus reduce
waste picking. In the years of 2004, the community collaborated with Kitakyusu International
Technology Association (KITA) Japan to improve technology on waste management that
resulted in the Takakura Home Method (THM). The milestone on environment governancewas designed in a simple way to process the organic waste resulted from the household
activities to reduce the volume of organic waste at family level. Made from a basket, skin ofrice as a filter, carpet, and organic bacteria and finally, it was patented by PUSDAKOTA forsocial purposes. About 4000 THM has been distributed to families in Surabaya and other
cities in Indonesia. KITA further developed the technology that is able to compost domestic
waste in seven day cycles generated from the largest market in Jawa Timur.
Transforming the slum teeming with unorganized residents into the green, healthy andhygiene-conscious community is basically success of the social workers to encourage urban
worker conducted the former work activities in rural area, as a farmer. As a pilot project, thecomposting communities in Rungkut Lor have been actively proliferating places with organic
vegetables and herbal plants in the spaces of their house. For the plants they use compost, as
the organic fertilizer, that resulted from the household composting process. One approach
favored by Pusdakota is the encouragement of partnership of waste collectors, which
commonly informal workers. Involving group of women, the movement expanded into othercommunities such as Kampong Wonokromo and Gadel. The communities develop plantationin their limited yard spaces to their waste management and effective communal work schedule.
In Kampong Gadel, another slump area, the community is chopping up the mounds of waste
vegetables and fruit that pile up around them from making sure that the waste is whittled
down to just the right size to fit into the “Bambookura”, a specially designed bamboo basket.
The waste processed activities have made compost ready to sell for Rp.500 per kilogram.
Another driving force to the eco-management is coming from the women movement of the
Family Empowerment and Welfare Coordinating Team (Tim Penggerak PKK) City of-213-

Surabaya which all of the leaders are wives of local government leaders. The head of theorganization which is the wife of the Surabaya Major enthusiasm enact local initiative topromote local movement on waste management. She manages the distribution of the national
subsidy programs, such as food subsidy program, health assistance for older people who areeconomically disadvantaged and baby health program for children from economicallydisadvantaged families. Now, it is a mandate for the women organization which spread forevery kampong in Surabaya to incorporate source separation of wet and dry wastes and thus
reduce waste picking.
Moving into Domestic Water Treatment
The water treatment model was initiated with community-based approach. However, at an
initial stage, the ceaseless outpouring of development agency’s initiatives were affecting the
local initiative and the overbearing burden of monitoring that development agency any
statutory funding program demonstrate a profound lack of trust and indeed respect for third
sector organizations. Secondly was some indication that the term originated in the voluntary
sector itself which now most keen to clarify the difference between volunteering andmandated activity. Unfortunately, the former donor policy made ‘easy money’ for thecommunities. Everyone who involved the activities initiated by donor will get allowance.
That made the traditional voluntary system was damaged. It has been raising question onsustainability of the ‘change’.
One of the key actors for improving water quality came is women communities. Dealing withhousehold daily activity, they are very sensitive with water quality. Wells were used toprovide water for non-drinking needs due to poor quality. They were relying supplies ofdrinking water from street vendors on a daily basis. It made them keep asking for some water
quality improvement programs. They has also raised some issues on the need of public toilets
and washing facilities. Conversely, male who spent most of their time for working at office orfactory preferred to improve road facilities. While a group of women and men were asked
about their role in social-ecological policy, they stated that they were capable of participating
on issues of domestic responsibility could be easily resolved with simple implementation,such as domestic waste management. However, they stand in a different relationship to theirenvironment, in particular that women group are more responsive to their household activities
related impacted the water. The group of men more concern on financial income and theirwork activities rather than their household environment.
Responding to those different interests, the community development program preferred to thevulnerable group, the women and children. Instead of conducting activities with children, theprogram arranged community movement for participatory water management. Starting fromset up a model of water embankment to reduce the annual flood in 2002, the program wasgradually moving into dealing with sanitation and water treatment. There were many optional
technologies to improve quality drinking water, such as chlorination, filtration (biosand andceramic), solar disinfection, combined filtration/ chlorination, and combined flocculation orchlorination. However, based on the urgent issue which risen by the community, the program
set up water embankment for three kampongs, locally called “rukun warga”. With pressure
from the local leaders, they believed that it would benefit community organization if they
were involved as they were often the people with hands on responsibility for resolving
individual and community issues. Without doubt, the leadership role of the women who
experienced as group leaders and consolidation the communities have been fundamental in-214-solving their housing problems and in successfully moving from an individual to a collective
vision.
To attain a sense of ownership of local communities which is very important for sustainability
and better management, the setting up of independent institution in communities is one of thecore important aspects of it. The best practice of solid waste management has opened up new
avenues for communities and confidence on them that they can do for clean water. What has
been done by social workers were just about listening the communities, raising their idea, andencouraging the communities to get the right to water. In those women organizations weobserved, there were informal hierarchical social networking. When critical decisions were to
be made, individuals often enlisted support above the level of their immediate superior. Thisis an informal network system for making decisions, particularly when the communities
determined the priorities issue. Moreover, the local leader pays more and more attention on
monitoring effort. As a consequence, the social worker reduces their monitoring effort. It canbe beneficial for the local social worker to volunteer to be the group leader. The model was
expected to encourage other kampong to adopt the best practices.
Competition with Local Government’s Initiative
Most of activities belong to government and private company rather than social enterprises
which should consider as blending the fields of entrepreneurship, social change, social
responsibility and venture philanthropy (Srivastva, 2004). With support from some private
enterprise and non government organization, the City Government of Surabaya also promoted
some local initiative to engage environment program. Emphasizing on basic physicalinfrastructure, Surabaya City engaged Kampong Improvement Program in 1990s which also
provided alongside the footpaths for the disposal of waste water and for rapid run-off of
rainwater. It facilitated each house to have its own septic tank which is emptied regularly.
Public toilets and washing facilities were also provided. A water supply network with standpipes was provided throughout the Kampung, with each stand-pipe serving 25-35 families.
Supplies of drinking water were also purchased from street vendors on a daily basis. Wells
were used to provide water for non-drinking needs and the quality of this water continues tobe improved. During the years 1984-1990, 70 km of access roads and 150 km of footpaths
were improved, 93 km of drains and culverts were constructed and 56,000 m of water pipe
was set up. Eighty-six public bathing, washing and toilet facilities were built (Silas, 1992).
Currently, the high-profile activity to promote Green and Clean Kampong has raisingcompetition to each kampong to dress up kampong. Conducting at the time to celebrate theIndependent Day in August, the City Government conducts annual competition to chosen thecleanest kampong. Some innovations have been coming up from local communities. Since
making green need more water, some kampongs have initiative to set up water treatment fromtheir home to ensure that their three get enough water supplies.
Along with support of some multinational corporations, the competition provide cash award
about Rp25 million or $3000 for each kampong. Those even organizers thenacknowledgement that the best kampong was their communities. There has been much dispute
over the acknowledgement of the actors behind the success of the best kampong. Some local
leaders disappointed that the ones who provided award to the competition (i.e. governmentand companies) admitted that the success to transforming their kampong belongs to theircorporate social responsibility. Rp 25 million was nothing compare to the community effort
for many years. However, other cities follow to hold the annual Green and Clean Competition.
Since being held in Surabaya, Jakarta is the second city which held the similar competition,-215-

following by the city of Jogjakarta. In 2008, it will also be held for the first time in Makassar,
South Sulawesi. It remained us with the hypothesis of Bebbington (2006). It is about thecredibility of elites and governments with such temptation to weaken, de-legitimize,
incorporate or indeed repress social movements. For community or development agency, suchgovernments can become the object of policy which the process can be fraught with tensions
both within government as well as in its relationships with other sectors of society.
Conclusion
In the case of Surabaya City, the most prominent characters in the pattern of promoting local
initiative takes the form of contribution and help in certain specific situation (short-run
program) than of maintenance on a more regular basis which has to deal with the complex
local paternalistic relationship. For becoming or sustaining a learning community, local leader
is the one who has the important role to make the best possible use of the knowledge of theworkers in the community. Involving within communities as a leader, development agencies
would invest on the human capital that holds the most valuable potential for community
learning. Unless integration community, implicit learning results in tacit knowledge, which iscontext-specific, personal and difficult to communicate. Moreover, the sustainability ofcommunity learning on dealing with clean water needs to be examined to the next challenge
on getting right to drinking water.

Introduction
The National Hydraulic Research Institute of Malaysia (NAHRIM) is a government institute(under the Ministry Of Natural Resources and Environment). NAHRIM engaged itself in
research and specialist consultancy in all aspects of water hydraulics and water environment.
As with most research organisation, NAHRIM aspires to become the premier water research
institute in Malaysia and also within Southeast Asia and to assume the role as an expert
referral centre in the same field. As part of this effort objective, NAHRIM is in the processof establishing a “National Water Information Repository Centre”.
It is a known fact that much of the researcher’s time is spent on finding information. Hence,the project aims to assist researchers in this tedious process by providing a point of access forwater related information. The Information Repository is currently being populated and when
fully developed, it can then not only serve the staff and management of NAHRIM, but also
the various government departments and agencies, academicians, consultants, students and the
public.
These users can have access to the information available in the repository to serve their needs
which can varies from research, design, planning and implementation, coordination,
environmental management, policies and decision support, socioeconomic activities andothers.
BackgroundThe basis for any information repository system has to be robust, easily expandable and easily
accessible to the many communities requiring the information. The vast availability of ICT
networks in Malaysia provides the passage and opportunity to allow for the smooth flow ofvast information and data and NAHRIM has taken advantage of the current advancement in
ICT to develop the system.
In hydraulic and water environment related researches, many types and format of information
are prepared, collected and analyzed. These collections of information will not be fully
utilised if it is not manage properly. Many valuable information lay idle and a lot of time canbe wasted in searching, collating and integrating of data needed for research where it may
already have been gathered by other researchers. There are instances whereby the same
information was collected over repeated number, at the expenses of public funds.

-218-

In order to avoid this duplication of efforts, an Information Repository centre was developed
where all water related information are grouped, categorized and digitized, to assist in all
water related research and development (R&D) activities.
One of the most significant aspects of this Water Information Repository is to provide
NAHRIM with a single water related information platform. It brings together experimental
data from many research projects into one consolidated searchable database. As more
research works are being done in NAHRIM, this repository will continue to grow andsubsequently become an increasingly significant asset to the country and the international
research communities.
Objective and Methodology
The objectives of the project were multiple including the creation of an Information
Repository that contains all the water related information available in NAHRIM. Hereinformation are digitize according to the respective R&D activities. The Information
Repository will act as an electronic support system within NAHRIM and can serve as theInformation Repository for other decision support systems.
The system that was developed also allows archiving of information that may otherwise be
scattered or even lost. The system has been designed to provide sufficiently comprehensive
and granular information so that they are informative and at the same time easily reused orprocessed for presentation in various formats to meet the user’s requirements which finallywill be used to generate a consolidated reports of various resource types.
During its first stage, that is the first six months of the project had been focusing around
NAHRIM research activities. However, in the second stage, new methods and tools will be
developed to make the information compatible with emerging standards, hence making iteasier to be linked and cross analysed with related information from other sources.
Currently, the focus of work covers the collection, compilation and development of theInformation Repository for the following divisions in NAHRIM:
a.
b.
c.
d.
e.

Research Center for River Management,
Research Center for Coastal Management,
Research Center for Water Resources Management,
Research Center for Water Quality and Environment, andHydraulic and Instrumentation Laboratory

From then, the information as translated into several main subjects including collecting,compiling and developing databases for the following repository:1.

9. Waternews, and
10. NAHRIM Water Information Repository Portal
The next step that was carried out is to provide an information management framework thatcan be customised to suit the needs of the Information Repository. The framework must
include facilities to manage the following types of information:
a.
b.
c.
d.

Documents in proprietary format,
Pictures, images, maps, charts and diagrams,
Records of reports, surveys, modelling outputs, field data, assessments etc.
Unstructured and semi-structured information in HTML and XML format.

The final step is then to store only inputs to and outputs information from modelling andanalysis applications for easy reference. It will not include facilities to process unprocessed
information as they will require custom built applications for their handling. For example
hydraulic engineering applications will include specialised methodology in their processing,analysis and presentation of the outputs.
What has been stored?
There are 9 repositories were developed to realize the need of researchers. The information
stored from various resources was mapped and group according to issue that related to
NAHRIM core R&D activities.

ObjectiveSpecial Features of the repository
NAHRIM Water Information Repository Centre shall be based on an information
management framework. The final framework when ready shall have the following
features:i)

Document management
The information source for the repository is most likely to be in the form of
documents in various formats. It is therefore crucial for the repository to beable to store and manage these documents in their native format. Users shouldbe able to browse and search for the documents available using metadata. It
should also provide support for hyperlinks and the definitions of these links inthe other documents in the repository. The repository should also be able tomaintain different filing structure of each division as it depends on their needs
and current practices.

ii)

Information architecture and structure management
The application to be developed for the various divisions in NAHRIM will
require customised information architectures to suit their diverse needs.
Information architecture is defined as the structural design of shared
information environments. It is the practice of structuring information for a
purpose.
In the Information Repository, the information architecture will be used as thenavigation structure for users to browse, explore, group and filter therepository. It will also be used as a place holder for the resources to be
captured.

iii)

Document-centric computing
All information stored in the Information Repository will be in the form of
documents. The information type identified will be entered using HTML
forms where these HTML forms will have to be designed to meet therequirements of the different resource types over their business processes.
These forms may require to be revised from time to time to meet new
requirements.
To ensure productivity and reduce errors in the information capture, theseHTML forms must incorporate various constraints and validation rules;
provide pick-lists based on the information captured in the Information
Repository. Information from existing documents may also need to betransferred to the forms during data entry to reduce inputs and typing errors.

-225-

iv)

Water related descriptors
A key to the success of the Water Information Repository is for similar
information to be described in a similar manner. This will help reduce
redundancies and ensure that the collected information can be easily comparedor consolidated. This requires the use of water related descriptors.
Descriptors are not to be confused with the term specification that engineers
and researchers are more familiar with. Specification specifies what isrequired whereas descriptors describe what is already there. The descriptors
list shall contain the descriptive fields for all the technical information
handled by the division. The descriptors shall be arranged into sections inline with the current practices of the division.
Where the descriptors are for quantitative information, a description of how
the quantitative information is to be determined must be provided together
with the recommended units of measurement.
Some descriptive fields may require a controlled vocabulary or qualitative
scales and these must be provided by the specialists together with descriptionsof the vocabulary used.
The highly discriminative descriptors must be identified so that when thedescriptors are used, they are mandatory.

v)

Ease and efficiency in populating the Information Repository
The Information Repository is generally found to be easy to be populated
either using a desktop application or a web browser. The desktop application
provides native access to all the information in the Information Repository
with extensive searching, navigating, filtering, export and import capabilities
which may not be available on the web-based applications.

vi)

Flexible querying and reporting abilities
The Water Information Repository collects all related information throughout
NAHRIM. It organises the information for study and make it completely
flexible for intensive reporting and analysis. In order to do so, a searchingfacility needs to be provided for the user, for example searching information
by full text or by common sets search.
The information can also be grouped under multiple categories and can be
related to any other information based on its relationship. This can be use to-226-

describe, summarise and compare data, hence providing a more meaningful
report generation.
vii)

Spaces and Security Policies
Each division in NAHRIM is given the privilege customized application for
their business processes and needs. Some work-in-progress information may
also be stored to serve the division needs and should not be exposed to users
outside the division. In other words, the divisions would like to work in theirown spaces.
Management, on the other hand is more interested in the final information andthe status of the projects in progress. They need to look at the information
across all the divisions. Typically the information may need to be grouped
into geographical units, resource types and time frame. Management may
also require consolidated reports across the various divisions. As such, themanagement space is different from the division spaces. Collaborators andother users will also require their own space.
The information stored in the data repository will require information indifferent subject areas to be stored in different models. The security policies
will need to be defined at model, folders, document types and resource type’slevels. Security policies can also be defined for the various actions that can beused for work-flow and documents updates.

Challenges
Among the issues and challenges faced in developing Information Repository are:
(a)
(b)
(c)
(d)
(e)
(f)

Content development must be based on industry practice and usage. This includes
descriptors categories in each information repositories.
Active participation from various divisions to process the reports and to populate
the repository and to take the ownership of the repository.
To ensure desk officers and support staffs are familiar with the informationarchitecture of their respective application and the various functionalities
provided.
Acquiring more reports and information in digital format to be used for
populating the repository.
Creating a critical mass of information in the repository so that it will become theprimary reference for water related technical information by the researchers.
Enforcing quality control measures to ensure the accuracy of the information in
the repository. This will determine the success of this project where the success ismeasure through quality, usefulness and also quantity of information available in
the information repository.

-227-

Development Progress
To date the development progress of the system is 80% completed and over 12,344
reports and document have been processed. The system is currently available for the useof researchers in NAHRIM.
For Waterpedia and WaterNews repository, these 2 modules are ready to be used.
However, from time to time refinement will be done to enhance repository.
Conclusion
Capacity building can be in varied form and one of them is through the provide access to
information. NAHRIM repository is aimed at that objective and hopefully will reduce theamount of time taken to produce research findings. Once fully populated it is hope to be auseful referral platform not only to NAHRIM officers but to those who are involved in all
aspects of water related research.

Abstract
With the rapid urbanization the provision of a safe and reliable water supply has become thebiggest challenge for urban areas of Pakistan. As compare to whole of the Asia, Pakistan has
the lowest water tariffs but still its collection is low due to people’s reluctance to pay forunsatisfactory service. Water and Sanitation Agencies (WASAs) which cover 44% of urban
population in Pakistan is responsible for Water and Sanitation activities in the urban areas ofthe major cities. WASA is able to recover only 50 to 60% of annual O&M costs at best. Thisis an unsustainable situation considering these figure do not include any debt servicing or
capital cost repayments. This paper will examine how the current situation may be improved
through introduction of public sector reforms, involving private sector, provision of technicalassistance, and improvements in service deliveries by capacity building and institutional
strengthening of WASA Lahore.
Keywords: urban water, public sector reforms, private sector involvement
BackgroundPakistan's population estimated at 135 million in 1999 is growing at about 2.3 percent
annually. Its water supply and sanitation infrastructure has already become inadequate to copewith this rapid growth though compared to the rest of the world and in particular thedeveloped nations, water consumption has very low figures in Pakistan (see Figure 1). Thishas forced the government to put potable water and sanitation at the top of the national
agenda and it is strongly reflected in Pakistan Water Sector Strategy (PWSS) (MOWP
2002) and the National Environmental Policy (NWP) (MOE 2005).

The Government's overall target was to provide safe drinking water to 68 percent andsanitation facilities to 44 percent of the total population by 2004 but it failed to meet thistarget due to numerous reasons. However, it is always blamed on limited financial resources.
Figure 2 shows the increasing gap between water demand and urban population over a 30 year
period.

Figure 2. Growth in Urban Population with corresponding coverage
Further, despite very low tariffs, collection efficiencies remain low pointing to the fact thatpeople are not satisfied with the quality of service provided and hence avoid paying. In
none of the cities in Pakistan there is a 24 hour 7 days a week water supply.
Water And Sanitation Agency (WASA)- Lahore
WASA was created in 1976 as subsidiary agency of Lahore Development Authority (LDA)
to take care of water supply, sewerage and drainage requirements in Lahore.

WASA’s failure as an institution to manage urban water supply remains at the heart of thecrisis and much of problem can be attributed to the quality of human resource and thestructure of incentives that govern the operation. The potential factor considered responsible
for the downfall and poor services are:Absence of legal and regulatory frame work.
Lack of alignment between the interests of WASA’s owner (LDA) and its primaryfinancier (Provincial Government)
Institutional constraints (Overlapping of activities between different departments such as
WASA, the Public Health Engineering Department (PHED) and municipal committees/
corporations).
Inability to recover costs and finance services locally which is further aggravated by pervasive
misallocation between capital and recurrent expenditures
Limited autonomy of WASA as financial support is coming from Provincial government
which is also interfering departmental human resource management and field operations in
the absence of human resource and career management mechanism.
Unrealistic development plans and inappropriate pricing of resources and services based on
outdated data
Insufficient personnel strength and capacity of the individuals in current organizational set
up.
Limited role and discouraging attitude towards local community and private sector
involvement
Poor working conditions, work acknowledgement and salaries of the staff.
Unfortunately till now every effort has been directed towards tariff increase and no real
attempt has been made in understanding the reasons of poor collection. In order to address
the key determinants, following three approaches are worth consideration:
Improvement in WASA’s performance without institutional reforms/realignment
Outsourcing / Privatization of selected activities of WASA
Introduction of Institutional reforms/realignment
Improvement in WASA’s performance without institutional reforms/realignment is seeked
through introduction of performance criteria and implementation of short term strategic andimprovement plans. The core values of this concept are:
Visionary leadership
Customer-driven excellence
Organizational and personal learning and capacity building
Valuing employees and partners
Innovative management
Informed management using geographical information system (GIS).
Social responsibility and environmental responsibility
For the visionary leadership, WASA has already hired professional Managing Directors (MD)at competitive market rates to act as the champion for this cause. Further, the Urban Unit
(Urban Sector Policy and Management Unit), formed under Planning and Development
Department, Government of Punjab is helping WASA towards development of a geographicalinformation system (GIS). It has already developed a geodatabase for the WASA major-232-infrastructure for up-to-date and informed decision making. New customer complains centres
whose complaints database can be directly accessed by the MD are under development. It is
hoped this will assist in implementing some kind of monitoring mechanism and will also help
in restoring customer’s confidence to pay WASA for its utility services.
In Pakistan both the National Water Policy (GOP 2008) as well as Pakistan Water Sector
Strategy (MOWP 2002) highlights the importance and the need for Private Sector
Participation (PSP) for the following reasons:Financial/Budgetary constricts of Public Sector Organizations
Expansion of existing infrastructure and introduction of new technologies
Assumption that Private sector works more efficiently than the public sector
However suggestion of outsourcing / privatization of selected activities of WASA have raised
many eyebrows due to misapprehension and misunderstanding about PSP in the provisionof urban water supply and sanitation services. Actually the concept of PSP in the municipal
water industry is still relatively new and it should be tailored to suit particular needs of acommunity bearing in mind constraints and limitations which are bound to exist in any
situation.Although there is little doubt that without PSP the future needs of a growing
urban population can never be met. But it is important to understand that private sector runs
the business solely for profit while water supply and sewerage are low tariff public utility
services usually taken for granted.
The foremost requirement for PSP to succeed is that of a strong regulatory framework.
The need for PSP is greatest where governments are weak and have failed to meet waterneeds of people. Unfortunately, the risks of PSP failing are also where governments are
weak and are unable to provide proper regulation and oversight to protect public interests(Bundschuh and Fuertes 2001). It is up to the governments to define and enforce laws andregulations.
Equally important is a legal framework under which PSP contracts are negotiated andawarded. The legislation should be clear and unambiguous allowing all stakeholders toenter into a contract which is fair to both and at the same time protects public interest. Thisrequires provisions ensuring the quality of service and a regulatory regime that istransparent, accessible, and accountable to public. Because contracts are usually mucheasier to enforce when signed with private parties, PSP should be encouraged, primarily for
improving the quality and the efficiency of the Water Supply & Sewerage (WSS) service.
PSP in WSS can take many forms (ADB 2006) such as:
Simple short term “Service contracts” for commercial (meter reading, billing, collection),maintenance (plants or networks), or non revenue water (NRW) reduction activities;
Medium term “Management contracts” with part of the remuneration of the Provider linked
to its technical and/or commercial performance;
Medium term “Lease” and “Affermage” contracts for which revenues from collections areshared between the Owner and the Provider; andLong term “Concession contracts” (with existing WSS assets transferred to the Concession
for its duration but still remaining owned by the WSS Utility)-233-

“BOOT: Build, Own, Operate and Transfer” for new plants and/or networks which bothtransfer most risks, including that of financing extension of WSS assets, to the Operator
and Joint ventures
Earlier on, an attempt to introduce PSP in Lahore failed due to ill conceived notions andthe process adopted. In 1998, a multinational British company was invited to carry out due
diligence and put forward proposals to privatize Lahore WASA. Negotiations took placebehind closed doors and a deal was almost finalized when nuclear testing resulted ininternational embargoes against investments in Pakistan. In 1999 LDA again entered into
negotiations with a private company, this time a German utility to privatize WASA but
again this failed due to lack of transparency and an absence of legal framework. Further
PSP approach is still unable to gain any in house support from the WASA operational field
staff.
To be successful, PSP in WSS requires significant preparation. The recently publishedtoolkit on “Approaches to Private Participation in Water Services” (World Bank/PublicPrivate Infrastructure Advisory Facility (WB 2008) explains in great detail the main steps tobe followed for implementing a “acceptable” PSP arrangement.
Introduction of Institutional reforms/realignment envision transforming the existing WASAs,
currently working under the Development Authorities, into autonomous, efficient,accountable, customer oriented and financially viable WSS corporatised utilities throughfollowing interrelated priority steps:
Transforming WASA into an autonomous entity, and establishing a renewed corresponding
institutional framework of accountability
Strengthening the new WASA, into a responsive well managed institution able to deliverworld class services in its jurisdiction
Preparing a business plan for the services including the strengthening and capacity building
programme, andDesigning and carrying out a integrated water and sewerage investment program
Preparatory and design activities required within the reformed sector structure are identified
as (FICHTNER 2006) :Sector objectives, goals and targets in such detail to be used as the basis for planning WSS
Legislate drinking water quality standards and monitoring responsibilities
Appoint independent technical auditors to monitor performance
Appoint financial auditors
Define detailed rules for tariff determination and make their implementation mandatory
Revise and clarify the appraisal criteria for investment funding and performance standards
Facilitate transfer of WSS assets and responsibilities for investment to local governments
Develop draft service agreements to be used by service providers to outsource O&M andother services
Given the time needed to establish new institutions and build their capacity, it is necessary toconsider transitional arrangements, particularly to deal with the planning and management of
new investments in WSS assets. The final organizational arrangement following transition isshown on Figure 5. It refers to a future condition in which the WSS providers are no longer-234-mainly dependent upon Provincial government grants for infrastructure development (> 10years in the future).

Source: (FICHTNER 2006)

Figure 5. Final Institutional Arrangements
At this point the Local Government authorities would have to take over the function of
performance monitoring in connection with tariff approvals. Each Tehsil Municipal
Administration (local government administrative unit) will establish a new WSS management
department with the following functions:
To have representation on the Supervisory Board of the WSS corporatised utility and thus be
involved in all governance issues
To prepare the statutes for the corporatised WSS utility
To recruit and engage the General Manager (GM) of the corporatised utility (paying at market
rates) and to establish performance contract
To review business plans inline with the Master Planning (co-ordination with urban planning)
To review tariff change proposals prior to approval by the relevant authority
To lobby for investment support to state institutions on behalf of the corporatised utility.
In order to ensure the success of the reform programme, the Government of Punjab will needto co-operate with the local government bodies and the service providers to prepare short-term
WSS projects for each city participating till the complete implementation of reforms.
Conclusion
As Pakistan’s population grows and economy develops, unconventional initiatives are needed
to meet challenges of rapid urbanization and water scarcity. It is the right time to understandthat without strengthening the institutions and defining a definite role for them, it will be
impossible to run the system in an efficient manner. It is significant to understand that
introduction of any change or reforms in the institutions in the absence of regulatory & legal
frame work as well as proper political backing will not deliver the desired results.
-235-

It is also imperative to recognize that the urban water service problems are not the result ofsome inherent properties of the services but are products of urban governance, the availabilityof human and economic capital, the political will and the strategic preferences. By identifying
the strengths and weaknesses of existing system this paper presented a framework for
promoting institutional complementarity through a cohesive governance system where
superiority of one form of governance takes shape depending on the issue in place.

Abstract
Problems of water resources are becoming important factors restricting social and economic
development of our country. Water resources of Mongolia are dramatically sensitive toclimate change that a small alternation in the precipitation might bring about severe water
shortage. In the recent 50 years, it is obviously warmer in southern of Mongolia than before.
The particularly obvious warming in winter had not only resulted in a greater evaporation andreduction of runoff volume, but also intensified the conflicting of water supply and demand.
The impacts of climate change on water resources are displayed in every sector of water
system. In this paper, we will pay attention to develop integrated water recourse management
plan.
Keywords: water, water supply, climate change, evaporation, precipitation, wastewater.
ClimateThe Mongolian climate is extremely continental with a short, hot summer and a long, cold
winter, high temperature fluctuation (both daily and seasonal) and a relatively high number ofcloudless days. The average annual temperature is between -7.8°C and +8.5°C (Figure 1,

Mongolia is situated in more sensible region with climate change than in many other regionsin the world. The main cause for this fact is that the country is located in a narrow inland-238-

transition zone between the great Siberian taiga and the Central Asian desert, highly elevatedabove sea level.

Figure 3. Spatial average of normalized annual temperature over Mongolia
In the past 60 years, the annual average temperature has increased by 1.9 °C; more
specifically, for the winter period by 3.6°C, the spring and fall period by 1.3-1.8 °C, and insummer time by 0.5°C (Figure 3). During this time, the annual average precipitation has
decreased by 10% within the country (Figure 4).

Surface water resources of Mongolia are composed of rivers (34.6 km ), lakes (500 km ) and3
glaciers (62.9 km ). The 36.5 % of the total lakes are distributed in the Gobi region and 410
33
km of total lake water resource 500 km , is fresh water. The 75.2% of the total glaciers are
the mountainside glaciers, the 21% are valley glaciers and the 3.8% are denudation surface
glaciers. The 50-70 percent of annual runoff of rivers in Altai mountain area forms from snow
and glaciers contribution, while 5-10 percent from rainfall. In case of rivers originating from
Khuvsugul, Khangai and Khentei mountain ranges, the 56-76 percent of annual runoff forms
from rainfall. Highest runoff is observed at Selenge-Sukhbaatar site. The variation of rivers
water resources is presented in Figure 5.

are presented in the Figures 9, 10, 11.
It is very important to determine climate impacts on the river regime and balance, andtendency according to the time and the space.

Climate change impact on surface water volume
Scenarios generated by the Hadley model (England) show that by 2040-2070 runoff will
increase in the Pacific Ocean basin and to a less extent in the Arctic Ocean basin. For theCentral Asian Closed basin it is expected that until 2040 runoff will increase a little and thenby 2070 runoff will decrease.
In 2004, meteorologist L. Natsagdorj determined that potential evaporation had been
increased by 3.2-10.3 % in steppe and Gobi region in last 60 years and 10.2-15.0 % instmountain and forest-steppe regions and in the first half of 21 century the total evaporation
will increase by 6-10 times than precipitation based on summarizing the total surface
evaporation studies estimated by other researchers.
Groundwater resources
The groundwater resources are formed differently depending on geological formation, climate,geomorphologic and hydrological conditions. In 1958, groundwater resources was estimatedfor the first time in Mongolia by the Russian scientist A.T. Ivanov and later, the Institute of
Water Exploratory Research (IWER) in 1973, Russian scientist N.A. Marinov (1977),
scientists G. Davaa, M. Myagmarjav (1999) and scientists Sh. Jadambaa, G. Tserenjav (2003)
estimated the groundwater resources using different methods. These estimations are
summarized in the following table.
In 2003, Dr. N. Jadambaa and G. Tserenjav estimated the groundwater resources that could be
used for economic use of pastureland, shown in the table 2. Their estimation was based on a
proposed distance between four water points in the whole territory of the country and it took
into consideration different types of water bearing rock formations and possible rates ofdischarge when calculating the groundwater resources.

Water quality
Surface water quality per basin
In terms of the assessment of surface water quality per basin, the surface water in themountainous region of Mongolia is fresh and soft, and it is included in the hydrocarbon
calcium classification. In the Arctic Ocean Basin which occupies 19.5 % of the territory ofMongolia, the Selenge River and its tributaries, the Sishged and Huremtei Rivers`
mineralization is at maximum 320.0 mg/l in winter. In summer, when it is fed by spring snow
melting and rainfall floods, the mineralization becomes at minimum 53.3 mg/l, pH =7.40-8.30(low alkali) and average hardness is 2.30 mg-ekv/l. At the all sample sites along Selenge river,water is fresh (mineralization is 200-320 mg/l), soft (hardness is 2.30 mg-ekv/l), withnd
pH=7.40-8.30 (low alkali), and belongs to 1-2 types of Hydrocarbon Calcium classification.
Near to upstream of Orkhon river, Ulaan, Tsagaan rivers and Tsenkher, Tsetserleg, North
Tamir, South Tamir, Khoshigt, Jargalant and Mogoi tributaries are very clear, soft and notaffected by human influences. The mineralization of Eroo river which is the biggest tributaryof Orkhon river is not more than 70 mg/l and the hardness is 0.30 mg-ekv/l. Therefore, thisriver is very clear, soft and its chemical composition resembles with rain water. The Kharaandriver belonging to 2 type of Hydrocarbon sodium and calcium classification is clear and soft.
All tributaries near to upstream of Tuul, are mountain clear, soft and not affected by human
influences.
In the Pacific Ocean Basin, the average mineralization for the Onon, Ulz, Kherlen and Khalkh
rivers is at maximum 120-300 mg/l and the average hardness is 2.0 mg-ekv/l. They haveconsiderable fresh and soft water.
-242-

In the Central Asian Internal Drainage Basin, the average concentration level ofmineralization of the Bulgan, Uyench, Bodonch, Buyant, Khovd, Tsenkher, Tsagaan, Sagsai,and Sogoot rivers with their tributaries which are Bokhmoron, Turgen, Ongi, Taats, Tui and
Baidrag etc. is about 60-450 mg/l, which is very fresh. Their hardness is 0.80-3.80 mg-ekv/l.
By research materials of surface water chemical composition, mineralization of most rivers is
mainly determined as 300-500 mg/l so that it is almost suitable for any economic sectors uses.
On the other hand, mineralization of the main lakes is different from each other. For example,
mineralization of Uvs, Khyargas, Khar, Boontsagaan, Sangiin dalai, Khukh and Oigon Lakes
is 2’000-15’000 mg/l, but mineralization of Khar Us, Khuvsgul, Buir, Tolbo, Terkhiin tsagaan
and Khoton Lakes is 50-300 mg/l.
Groundwater quality
Mongolian ground water quality and chemical composition can be defined by 4 physicalgeographical zones.
The Khangai- Khenti mountainous region involves most of the forest steppe area (30% of
Mongolia) and covers the northern part of the country. The mineralization of the samples
taken from this region range between 100-800 mg/l, with rare exceptions of having >1000
mg/l. Average mineralization equals to 450 mg/l. Hardness of water in the region equals to
4.5 mg-eqv/l.
The Altai mountainous region involves Mongol Altai, Siilhem, Kharhiraa, Turgen and GobiAltai mountains of western Mongolia. Average mineralization for the region is 640 mg/l andhardness is 4.8 mg-eqv/l which is higher than the previous region. The water for the region issalty and fluorinated.
The Mongolian Dornod steppe region’s average mineralization is 950 mg/l, average hardness
is 5.6 mg-eqv/l and it is characterized by a high concentration of iron.
The average mineralization for the Gobi region is 1120 mg/l and hardness is 5.4 mg-eqv/l
which exceeds the standard for drinking water. Water quality in more than 100 soums does
not meet the drinking water quality standard since 60% of the soums have water rich inmineralization, 40% have high hardness and over 80% of them have a high magnesiumhardness degree.
The groundwater mineralization and chemical composition of the Mongolian territory arechanged from north to south by principle that the chemical composition is altering fromhydrocarbon into sulphate, then chloride but cation altering from calcium into magnesium andsodium.
Water pollution
The regime and quality of water resources become more and more affected by human
influences, global climate warming and changing soil and vegetation cover to. A state
inventory for surface water conducted in 2003 showed that although most of the rivers stillcontain mountain fresh water, for at least 28 rivers in 8 provinces riverbeds have changed
and/or are polluted due to mining activities. For example, the large Orkhon, Tuul, Kharaa andEroo rivers in the Selenge river basin have been polluted from the impacts of gold mining
industries, urbanization and industrial activities within the basin.
-243-

As impacts of mining activities, the aquatic ecosystem with insect and fish populations havebeen changing. Fresh water fishes cannot survive in heavily polluted blurry rivers and theamount of fishes which get infected by diseases is increasing. Groundwater sources which areclose to Ulaanbaatar city and other bigger cities are polluted by urban waste and garbage since
the regulations for protected zones are not obeyed.
Water resource scarcity
In recent years, water resource scarcity is appearing in some regions from reason of climatechange and human impacts.
A state inventory for surface water conducted in 2003 shows that the total number of rivers in
Mongolia is 5565 and from them 683 dried out in the last few years. Also 1484 springs of
total 9600 springs and 760 lakes of total 4193 lakes dried out.
According to the LANDSAT7 satellite information of the glacier study in Kharkhiraa, Turgen,
Tsambagarav and Tavanbodg mountains, the glacier area decreased by 30% from 1940 to2002
A state inventory for surface water was conducted again in 2007. As the preliminary result,the abovementioned situation has become worse that the total number of rivers in Mongolia is4290 and from them 887 dried out. Also 2096 springs of total 7244 springs and 1164 lakes of
total of 2569 lakes have dried out. These results show that the water resources are rapidly
becoming scarce. Water resource scarcity raises trouble for state, public and water user andneeds to be well concerned on account of life base. A comparison of the state inventories forsurface water conducted in 2003 and in 2007 is presented in the following figure.
Conclusions
Because of its geographical location and rugged topography, Mongolia is highly vulnerable toanticipated impacts of climate change on water resources. Due to the cross cutting nature ofwater resources, increased mean temperature, recurrent drought and floods, retreating glaciersand permafrost, and more intense and infrequent rainfall patterns will have a wide ranging set
of impacts on water resources.
Water is most likely source of conflict, with different sectors for resources that will in many
places become scarcer. These increased vulnerabilities to climate hazards will compound
current water governance problems in Mongolia. Therefore, governance structures and water
use practices will need to adapt to climate change. Good examples of Integrated Water BasinManagement should be developed.

Legislative Approach to Water Quality Management in Malaysia – Success andChallenges

HASHIM DAUD
Director (Marine and Water Division)
Department of Environment Malaysia

Introduction
Water resources in Malaysia come in the forms of rivers, lakes and groundwater. As long as
we can remember, rivers have served as the sole source of water supply for our consumption
in almost all parts of the country. Since achieving independence, the country has developed
itself in leaps and bound from an agriculture-based society to an urbanised and industrialised
nation. Both this shift and a rapidly growing population have threatened rivers as a vital
source of water supply. In addition, the river water quality has deteriorated making its
availability for consumption much more difficult than in the past. The continual pollution ofrivers will deplete this water resource even further and will have serious repercussions on thenational agenda to become a fully developed nation by the year 2020 if essential steps are nottaken to improve our river water quality. This paper describes the legislative approach towater quality management in the country, and its success and challenges.

National Policy
The National Policy on Environment states that the nation shall implement environmentallysound and sustainable development for the continuous economic, social and cultural progressand enhancement of the quality of life of Malaysians. It is based on eight inter-related andmutually supporting principles and where water is concerned will include the sustainable useof water resources, conservation of a river’s vitality and diversity, and the continuous
improvement of its water quality. The policy outlines the strategies and measures to be taken
towards an effective management of water resources, pollution control and prevention ofenvironmental degradation. A holistic approach is required to manage our river water quality.
Water quality management
Legislation
Laws are used as a form of management response to environmental problems in Malaysia.
Amongst the laws relevant to water quality management include the 1929 Mining Enactment,
the 1930 Waters Enactment, the 1954 Drainage Works Ordinance and the 1974 Street,
Drainage and Building Act. These laws are largely sectoral in character and focused on
specific areas of activity. The increasingly complex environmental problems faced by
Malaysia required a comprehensive piece of legislation which came in the form of the 1974
Environmental Quality Act. The Act came into force on 1 April 1974 for the abatement andcontrol of pollution and enhancement of the environment.
Three pieces of subsidiarylegislation were formed as an initial legislative approach to water quality management. Thesewere:( i ).

Environmental Quality (Prescribed Premises)(Crude Palm Oil) Regulations 1977;-246-

( ii ).

Environmental Quality (Prescribed Premises)(Raw Natural Rubber) Regulations 1978; and( iii ).

Environmental Quality (Sewage and Industrial Effluents) Regulations 1979.

Sources of pollution that threatened our water environment have been subjected to theseregulations since the 1970s. It is essentially a command and control approach utilising
effluent discharge standards. For pollution sources upstream of public water supply intakes,
the effluent discharge standard was made much stricter than those downstream of such intakes.
In addition to making use of these laws to control pollution, additional legislation is also inplace to effect prevention of pollution into a river or water body. A third mechanism
involves a continuous assessment or monitoring of all the rivers in the country to ascertain the
improvement or otherwise of our river water quality.
Prevention
The legislative approach in water quality management effected by the 1974 Environmental
Quality Act makes use of Section 34A where a report on impact on the environment resulting
from prescribed activities (EIA requirement) is mandatory. Among the prescribed activities
or projects that can cause water pollution include airport, housing, industry, mining,
petroleum, power generation, resort and recreational development, and waste treatment anddisposal facilities.
For non-prescribed activities, site suitability evaluation would also be carried out so as toassess the capacity of the area to receive additional pollution load and the requirement for
waste disposal.
The Environmental Quality (Sewage and Industrial Effluents) Regulations 1979 also requirethat written permission be obtained before the construction of any building or carrying out
any work that may result in a new source of effluent or discharge.
Water Pollution Sources and Control
Malaysian rivers are degraded by both point and non-point sources of pollution. The major
point sources of pollution are sewage treatment plants, agro-based industries, manufacturingindustries, sullage or grey-water from commercial and residential premises, and pig farms.
Non-point source (or diffuse) pollution is largely due to storm runoff after a downpour.
Earthworks and land clearance activities contribute to siltation of rivers and can be both point
and non-point sources of pollution.
Agro-based industries
The earlier post-independence years saw a proliferation of agro-based industries such as raw
natural rubber factories and palm oil mills which polluted our rivers. The control of pollution
from these sources involved a combination of both economic and command-control
instruments which has proven to be very successful. These industries did not only invest in
pollution control research and development but also made great efforts to comply as rapidly
as possible with the stipulated effluent-discharge or land-disposal standards. They were
induced to install effective wastewater treatment systems instead of paying the prohibitive-247-

effluent-related or pollution fees imposed under the licensing requirements that came into
force since 1977. The organic pollutant load dumped into rivers has been greatly reduced bymore than 90 percent of the total load generated.
Manufacturing industries
A new set of environmental problems emerged as the nation progressed in its industrial
development. In addition to organic pollutants, manufacturing industries generate inorganic
pollutants, toxic wastes and persistent organic pollutants. All manufacturing industries are
required to install wastewater treatment systems to arrest their water pollutants before being
dumped into rivers.
The achievement in controlling effluent discharges from thesemanufacturing industries varies from industry to industry. The small and medium scaleindustries have difficulties in complying with discharge standards. Constraints cited include
financial problems and lack of space for the construction of wastewater treatment facilities.
The manufacturing industries are encouraged to implement alternative options such as
cleaner production, waste minimisation and waste re-utilisation in order to reduce waterpollution further. Such options could also enhance production efficiency, reduce waste
generation and thereby its final disposal cost. They are also encouraged to adopt theapproach of self-regulation and strive for ISO 14001 Certification not only to ensurecompliance with discharge standards but also to attain competitiveness in the global arena.
Efforts are also being stepped up to eliminate indiscriminate disposal of toxic wastes anduncontrolled release of persistent organic pollutants. The management of toxic wastes isbased on the cradle-to-grave concept. There are laws in place to control their generation,
storage, transportation, treatment and disposal. An integrated state-of-the-art treatment anddisposal facility has been set up and is in full operation since August 1998 to assist the
manufacturing industries in the proper management of their toxic wastes.
Sewage Disposal and Sewerage Works
Sewage is a major polluter of our rivers. This is a problem of the past centuries that
continues to plague the nation as it enter the 21st century. Initial efforts to control sewage arevery much focused on protecting public health but there is now a gradual shift to protect water
resources and the natural environment.
A private company has been tasked to manage
sewerage works and sewage disposal in the country since 1994 but
currently it is only
responsible for 86 out of 144 local authority areas. The management of sewerage in these 86
areas is far from holistic since there are sources that do not come under the private company
such as private sewage treatment plants, individual septic tanks, sewage from primitive
systems and discharges of raw sewage from squatters. There are still a lot of efforts required
and measures needed to reduce the sewage pollutant loads so that river water quality can be
improved.
Sullage (Grey-Water)
An important source of point pollution is sullage or grey-water which originates fromresidential and commercial premises but is often overlooked. The wastewaters can comefrom places such as kitchen sinks, bathrooms, washing machines, restaurants, wet markets
and car washing centres. As rivers pass through urban areas and populated places the sullage
will become a major contributor of water pollution. Usually a stream in an urban area does
not have enough assimilative capacity to absorb pollutant loads and will contribute organic
pollutants, ammoniacal nitrogen and nutrients to a river nearby. At present, sullage is not-248-treated and poses a problem to improving river water quality.
Pig Farming
Pig farming cannot continue to be a backyard industry if it is to flourish in the country. This
industry has a high demand for water and discharges large quantities of wastewater into rivers
with a high organic content. Designated pig farming areas are required not only to ensure aproper control of its wastewater discharges but also for disease control.
Non-Point Pollution and its Control
Non-point pollution is pollution that comes from many diffuse sources and is associated with
rainfall moving over and through the ground. As it moves, the runoff picks up and carries
away natural and man-made pollutants, and deposits them into lakes, rivers and even groundwater. This runoff pollution can come from many different land uses over large areas and is
far more difficult to control than pollution from point sources. One of the best ways tocontrol this pollution is to implement best management practices.
There are at least three types of runoff pollution in the country. Firstly, agricultural runoffthat carries pollutants that originate from activities such as pesticide spraying, fertilizing,
planting, harvesting, feedlots, cropland, grazing, plowing and irrigation. The runoff willdeposit manure, fertilisers, ammonia, pesticides, livestock waste, oil, toxins, soil and sediment.
Good agricultural practices are required to manage these activities so that runoff pollutants areminimized.
Secondly, forestry runoff associated with activities such as timber harvesting, removal of
streamside vegetation, road construction and use in forested areas, and mechanical preparation
for tree planting Good forestry practices are required to minimize soil erosion and siltation,
destabilisation of stream banks and disruption of river habitats.
Thirdly, urban runoff that will deposit many and high amount of pollutants into rivers andother water bodies. Some of the measures that can be implemented include installing storm
water filter to treat drainage and runoff, construction of gross pollutant traps at appropriate
places, maintaining vegetation as filters along contours, and constructing wetlands whereverfeasible as a good revegetation practice to improve river water quality.
The control of non-point pollution is far from satisfactory but the problem is not unique to thiscountry. Its control is also a major challenge in other parts of the world including the US andcountries in Europe.
Erosion and Siltation Control
In the pursuit of national development, the country has embarked on rigorous land clearance
activities and many earthworks for constructions purposes. These have resulted in soil
erosion and the dumping of sediments into rivers. Significant negative impacts on the rivers
are occurring not only in the form of siltation but also losses of river habitats. Control
measures are necessary to be imposed on developers to comply with the “Erosion of Soil andControl Plan” made by the Drainage and Irrigation Department and also the “Guidelines forPrevention and Control of Soil Erosion and Siltation” issued by the Department ofEnvironment (DOE).
River quality monitoring
The DOE has established a river monitoring network since 1978 to establish the status of river-249-

water quality, to detect changes in the water quality and wherever possible to identify
pollution sources of rivers.
It also serves to support environmental management andplanning in the country. There are 1085 water quality monitoring stations sited within 140
river basins throughout the nation. The monitoring programme includes both the in-situ
measurements and laboratory analyses of as many as 30 physico-chemical and biologicalparameters. In addition, 15 automatic water quality monitoring stations are installed to detectchanges in river water quality on a continuous basis at strategic locations on major rivers
basins. Water quality levels for specific parameters can be transmitted real-time to the DOE.
Between the years 1998 to 2005, the numbers of clean rivers have risen from 33 to 80 while
polluted rivers remained between 9 and 15 (see Figure 1). Over the some period the numberof polluted rivers, as measured in terms of biochemical oxygen demand (BOD, ranged
between 14 and 31 rivers (see Figure 2). This organic pollutant originated from agro-basedindustries, manufacturing industries, sullage, pig farms and sewage. The estimated BOD
loads from agro-based industries, manufacturing industries and pig farms were dwarfed by the
BOD loads from sewage (see Figure 3). This suggests that while industries and pig farms aremajor polluters nevertheless sewage remains as a significant major polluter whose loadingneed to be reduced drastically.

Challenges
In addition to challenges outlined earlier there are a number of other challenges that need to
be given consideration. The uniform discharge standard is applicable throughout the country
and does not take into account the assimilative capacity of a river or water body. For better
protection, there is a need to develop river or stream standards and for effluent discharge
standards to be set accordingly in order to comply with these river or stream standards.
A number of sources are not able to comply with existing discharge standards and there is anecessity to review these standards to be in line with current acceptable international
standards and availabity of treatment technology.
Some State governments are requiring palm oil mills to comply with much stricter discharge
standards than those imposed by the Federal Government.
Conclusions
The legislative approach in water quality management using the 1974 Environmental Quality
Act has been successful in reducing pollution to a certain extent. It has involved pollution
control, prevention of pollution and continuous assessment (monitoring) of the riverenvironment. There are still many challenges that need to be addressed to achieve a holistic
water quality management. Much of the past and present efforts are very much directedagainst controlling pollution from point sources while non-point pollution probably continued
unabated. The necessary technical, institutional and legal arrangements are also necessary totreat sullage (grey-water) adequately before it is discharged into rivers. The nation willcontinue to use the water from its rivers for many years to come and it is imperative for theauthorities to reduce pollutant loads and improve river water quality on a sustainable basis

Abstract
Urban rivers are vulnerable to different processes and activities that pollute and degrade the water
ecosystem. Restoring their health poses a huge challenge to governments and other actors. This paper
examines a ‘success’ case of a LGU-initiated river rehabilitation program in the Philippines in two
sequential phases; the first phase which targeted physical restoration of the riverbanks and solid waste
clean-up of the river (1992-1996) and the second whose main task is mitigating liquid discharges andimproving river water quality (currently ongoing).
Despite noteworthy achievements at the local level, effectively addressing two no less difficult tasksof trans-boundary nature of the water quality problem and the integrated and adaptive management
required for maintaining healthy rivers seems to lie beyond the overall capacity and mandate of thelocal government in a decentralized system of government in a developing country such as thePhilippines.

Introduction
Urban rivers are vulnerable to different urban processes and activities that cause pollution anddegradation of the water ecosystem. Restoring the health of rivers poses a huge challenge togovernments and other actors in the public domain. While the rehabilitation and/or restorationof urban rivers in developed countries offer measures and pathways to follow for developing
countries, the differences in circumstances between the developed and developing countries
including the various local conditions do not warrant simple replication and immediatelytransferable fixes.
Developed countries are able to effectively clean up their rivers backed up by adequate
resources, strong public sector capacity and public institutions whereas developing countries
struggle to rehabilitate theirs in the context of limited capacity and resource base and, often in
the absence of appropriate public institutions, legal framework and strong regulatory
enforcement capacity. This is particularly so in many local government units (World Bank,
2007). The Philippines is no exception. Decentralization resulting from the Philippine Local
Government Code of 1991 had local governments grappling without the necessary power,
authority, resources and training to manage a plethora of urban resources, facilities andactivities (UNESCAP, 2006).
The Manila Times (2006) reports that water quality throughout the country has been
deteriorating owing to high population growth, rapid urbanization and industrialization. As
early as 1996, monitoring of the country’s rivers showed that only 51% of the classified rivers
still met the standards for their most beneficial use. The rest were already polluted from-253-

domestic, industrial and agricultural sources (EMB, 2007). The major source of waterpollution is domestic wastewater, accounting for 48% of the total pollution sources. Whiledomestic wastewater is pinpointed to be the principal cause of organic pollution of water
bodies, only 3% of investments in water supply and sanitation were going to sanitation andsewage treatment (EMB, 2007). More than 90% of sewage is not treated and disposed of in anenvironmentally sound manner. Residents rely on private solutions such as open drains andpoorly constructed septic tanks to dispose of human and liquid wastes thereby polluting anddegrading the surrounding urban areas and water bodies (Manila Times, 2006). It is no
surprise that the Department of Environment and Natural Resources-Environmental
Management Bureau (DENR-EMB) lists the rehabilitation of rivers as one of the key
challenges faced by the country. The bureau initiated a Sagip Ilog Program (Save Rivers
Program) and selected 19 priority rivers, including Marikina River for monitoring.
The River Rehabilitation Program
Marikina River is the town’s main waterway and is a major tributary to Pasig River. It
stretches from Rodriguez, Rizal to Pasig City. During its heyday, it was the picnic ground of
the town folks who held fiestas in the vicinity of the river. But some four decades ago, theriver was all filth and stench due to uncontrolled encroachment and indiscriminate disposal ofboth domestic and industrial wastes causing the deterioration of its water quality (Fernando,
1994). Borje et.al. (2004c) writes that the river merely served as a dumping area and no one
ever dared to go near it.
The ‘Save the Marikina River’ Program was then conceptualized and implemented to revive
by rehabilitation the Marikina River and its environs and, develop it as the city’s biggest
recreational and sports area. The program was implemented during the incumbency of former
1
Mayor Bayani Fernando (1992-2001) as stipulated in his Program of Government. The
former Mayor even promoted a program’s principle;
The people have to touch and smell the water. It is hoped that this experienceand exposure will galvanize them to muster enough political pressure for thegovernment and the rest to act and conserve the river (Fernando 1994, p. 1).
The Mayor intended to showcase river rehabilitation not simply as one of those government
programs on environmental preservation, but to communicate to his constituents that the local
government is seriously working on such a program and that it is its business to entice them toclean up, follow what the laws say about sanitation, encroachment, among many others (Borje
et.al., 2004c).
Marikina City started river rehabilitation work since the early part of 1993, without any
completion date. After more than a decade of development, the landscape was transformed
from being much polluted, flood-prone and adorned with informal settlements to one with
free-flowing water, less flooded areas and with river park amenities such as an 11-km
jogging/biking lane, skating rink (reportedly the biggest in the country), tree planting pockets,
picnic and play grounds, sports amenities like baseball field and basketball court, a YouthCamp, a Chinese Pagoda, a Roman Garden, a gazebo, a riverboat, floating stages,
1

Now Chairman of Metro Manila Development Authority (MMDA), Bayani Fernando served three consecutive
terms (equivalent to nine years), as Mayor of Marikina-254-amphitheater and a Senior Citizens’ Lifestyle Center (Borje et.al., 2004c). The task ofrehabilitating was by no means simple. It involved relocating riverbank communities,
addressing flooding problems and conducting dredging operations before the river had to be
developed into a recreational park. These interrelated issues were dealt with strategically fromthe top while specific projects and activities were assigned to particular Departments and/or
Offices within the city. The then Mayor oversaw the general plan and had the direct and final
word on many aspects of it, a case illustrative of a top-down management style.
The events leading to the creation of the Marikina River Park generated mixed responses fromthe relocated communities, national government agencies and international organizations.
Some of the informal settlers in the river were receptive while others were indignant. But
more than a decade after the relocation, the affected communities are generally more satisfied
with their present conditions having more secure lands and houses with improved access to
infrastructure, community facilities and services. These present circumstances seem to‘justify’ the non-consultative and compelling nature of the demolitions in the past.
The City’s rehabilitation program received various citations and awards as well as further
support for related supplementary projects. But even if the river had been cleaned of its
squatter settlements, which were believed to be major sources of pollution in the past, water
quality remains to be a big problem and domestic sources account for much of the pollution
loading according to an article in Manila Water (2007) so then the city turns toward abatingwater pollution and improving the river’s water quality via the introduction of Wastewater
Treatment Plants (WTP). The latter project not only advocates for the construction of WTPs
all over the city, but also calls for the appropriate construction of septic tanks in order toprevent groundwater contamination.
The Clean Water Act of 2004 provided, in part, the impetus for Marikina and Manila Water tocoordinate efforts at treating wastewater, the latter being the agency mandated to provide
water and wastewater services in the city. Further partnerships were also entered into by thecity giving birth to the ‘Clean Water, Clean River’ project with USAID’s ECO-Asia as theprimary funding institution. These collaborations thereby created a different management
structure for the city’s water quality improvement project, now including the private sector
and the donor agency, both of which have their own upheld organizational norms andprinciples. While Marikina may not be obligated to Manila Water, it is compelled to respect
and follow the working principles of USAID, having signed a memorandum with it as thedonor. This meant a compromise from the top-down, local government-centered planning andimplementation of the first phase to a more collaborative approach on planning with theparticipation of stakeholders as espoused by the donor agency.
Interestingly, the policy instruments used by the local government have also been greatly
influenced by its donor, with particular focus on information and education campaign or‘social marketing’ in the second phase. These have not only informed people but have also
involved representatives in the planning process at their respective level and area. A
regulation on septage management is underway also but there is very little mention of
incentives for treating wastewater. On the contrary, individuals who avail of the wastewater
service may be asked to pay for the service thereby complicating the problem for a service
that is new and an (environmental) aim which has been sought after by Marikina City alone.

Marikina River Rehabilitation vis-à-vis Comprehensive River Management
Marikina was successful in removing and relocating previous riverbank communities into incity resettlement sites. It also provided those resettlement sites improved access to basic
services, infrastructure and communal facilities such as basketball courts, playgrounds andcommunity halls (MSO, 2007). The local government also boasts of an effective solid waste
management system, with a garbage collection efficiency rate of 98% (WMO, 2007). The
system had been established with the aim of preventing direct or indirect dumping of solid
wastes on waterways. Another component which the local government was also able toaddress is the problem on flooding. The LGU improved the river being the city’s principal
drainage system through massive dredging operations and bank improvements. Flooding was
reduced significantly from that which used to cover an area of about 27.52% (6.4 km2) of theentire city in 1992 to 19.04% or 4.4km2 in 2004 (Borje et.al., 2004a). Floodwaters also recede
faster due to the decreased build up of sludge at the riverbed. Finally, the city developed thewhole stretch of the river into a recreational park. Trees were planted on the banks to prevent
erosion and communities field their own patrols to stop those who dump garbage (Gallego,
2004). Mini plazas were created and these provided venues for programs and games thereby
bringing back a sense of community seldom seen in the harried world (Ramos, 1994). In fact,
the World Bank and National Disaster Coordinating Council (2004) reports that thedevelopments in Marikina River indirectly benefited the LGU in terms of higher property tax
revenues resulting from a 10-fold rise in property values.
Despite these improvements, the river ecosystem particularly in terms of its water quality andthe species that thrive in it are two major challenges which the local government is struggling
with. Water quality remains to be worst than class D according to the Laguna Lake
2
Development Authority (2005) and the river is suffering from Pterygoplichthys pardalis
infestation. Although these do not pose any direct threat to humans and other fishes, they
multiply rapidly, eat voraciously, compete with other fish for food and further eat the eggs ofother fish species thereby causing the latter’s depletion. They also bore holes on the soft,
muddy banks to create breeding nests, damaging the river’s plant life and causing the river’s
sides to erode (ADB, 2006).
Furthermore, while the rehabilitation of Marikina River has been well-recognized by local,
national as well as international organizations, the efforts remain confined and concentrated toMarikina alone. There is no steering committee, no legal and institutional framework inmanaging the entire river basin, over and above local administrative boundaries. As well, thefact that the river and its rehabilitation brought fame not only to the city but also to its leader
may have affected other politicians who would like to build their own legacies and therefore
choose to have different priorities and programs. In any case, the program was exclusively
done by the city with very limited interaction and collaboration with those outside of thecity’s sphere of influence.
Although the exclusivity in the first phase offered ease of control for the LGU to direct its
resources in solving its riverbank squatting issues, flooding as well as solid waste
2

The rise of Pterygoplichthys pardalis, more commonly known as janitor fish posed greater problems not just in
Marikina but also in neighboring Pasig River and Laguna Lake. This affected fishers who now report reductionof fish catch and loss of livelihoods and incomes. The DENR and other agencies are still experimenting ways tocurb Pterygoplichthys pardalis infestation in these water bodies.

-256-management problems, the second phase needed to address the trans-boundary nature of thewater and therefore its vulnerability to pollution from different sources. Even with the passing
and implementation of the Clean Water Act four years ago (2004), there is still no
institutional framework or river basin plan established mainly for the management ofMarikina River. Marikina City, per se, lacks the financial capability, technical expertise andappropriate technology as well as local knowledge and awareness on sanitation and theenvironment (ECO-Asia, 2006). The lack of funds compels the city to seek and maximize
external sources of funding for its programs. It had since then partnered with Manila Waterand USAID’s ECO-Asia, the former for the provision of WTPs in strategic areas in the citywhile the latter for capacity-building, social marketing and a pilot project on decentralized
WTP. The city resorts to incremental and decentralized approaches to wastewater treatment
instead of the more expensive centralized WTPs. These approaches, in turn, requiresignificant levels of community mobilization and stakeholder cooperation in the operation andmaintenance of the systems.
Conclusion
River rehabilitation is a complex environmental management program so that its planning andmanagement need to adapt to the change in circumstances. This is the challenge in the second
phase, with river water quality improvement heavily dependent on community support andexternal donor provision due to the lack of public funds. The question on why therehabilitation of Singapore River only took ten years to conclude its success can partly beanswered by the availability of resources and the enhanced capability of the nation-state toaddress its problems (UNEP, 1997). On the other hand, developing country cities such as
Marikina lack the necessary capacity in terms of expertise and funding required to fully
undertake infrastructure projects so that it must rely on other means of ensuring sustainability,of balancing economic development with resource conservation and environmental resourcesmanagement (UNESCAP, 2006). While developed countries have already looked into
adaptive, integrative and river basin management frameworks that cross local administrative
jurisdictions, urban rivers in developing countries have yet to establish institutionalframeworks that effectively operate over and beyond the political boundaries of local
governments. Marikina illustrates a local initiative that is neither shared by any other city nor
municipality in the entire River Basin despite the fame of the river’s transformation. Although
the nature of the water quality problem in the river is trans-boundary, there was not and there
is no river basin commission created to govern the river so that the efforts of Marikina areweighed down by continued pollution coming from elsewhere. Public participation in water
resources management processes has also been limited and only very recently initiated by the
local government, which according to Lorenzo (2007) is still bureaucratic.
The case proves the claim of the World Bank (2007) on the limited capacity of LGUs ingoverning environmental and natural resources. As posited by UNESCAP (2006), local
governments need to be trained in managing urban resources, facilities and activities they aremandated and authorized to govern. Aside from this, it must be noted that while there had
been widespread decentralization since the 1980’s, nature does not follow political andadministrative boundaries set by governments. As such, local initiatives will remain
insufficient no matter how participatory and inclusive the planning had evolved to include
communities and various stakeholders. Unless and until the entire resource is managed
holistically, the problem on pollution and mismanagement remains. The Marikina River
Rehabilitation Program indeed demonstrated how small initiatives can generate noteworthy-257-

improvements and enthusiasm from various groups. At the same time, it also highlighted thelimitations of these local initiatives in improving the overall condition of a publicly sharedresource. Environmental management, water resources and river management, in particular,need to be integrative, adaptive and, more importantly, to cross political boundaries. These
management modalities tend to go against the principles of decentralization with its(fragmented) management of resources based on territorial jurisdictions.

Overcoming Pollution in Japan and the Lessons Learned

Hirokazu Iwasaki
Deputy Director, Water Environment Division,
Environmental Management Bureau, Ministry of the Environment, Japan

Abstract
In the 1950s and 1960s, Japan experienced unprecedented environmental pollution andaccompanying health damages, or so-called pollution diseases. The four major ones in Japan
are Minamata Disease, Niigata-Minamata Disease, Itai-Itai Disease and Yokkaichi Asthma.
Other Asian countries are now experiencing, or are going to experience, environmental
degradation including pollution as their economies develop, but the distress caused bypollution in Japan should not be repeated by its neighbors. This paper describes the severe
water pollution Japan experienced, how Japan overcame it, and the efforts being made bygovernments and enterprises to alert other countries not to make the same mistakes as Japan
made.

Introduction
Pollution problems in Japan occurred as early as the Meiji era (in the late 19th century). The
Ashio Copper Mine mineral poison case is recognized as the original pollution problem inJapan. The Ashio Copper Mine opened in 1610 and after its control was transferred to a man
named Furukawa in 1877, the extraction of copper increased after the discovery of new veins
and the modernization of production technology. It eventually grew into the largest coppermine in Japan. On the other hand, slag flowed into the Watarase River (especially during
floods) from around 1890, destroying fish populations and causing damage to crops. The
aggrieved farmers made petitions to the prefectural government, submitted written inquiries tothe Diet, and resorted to other tactics. As a result, the Ashio Copper Mine mineral poison case
was addressed by Japan’s Diet in 1891. Even so, the company failed to take any substantial
steps to prevent further pollution. It was not until 1974 that the Furukawa mining plant
consented to pay ¥1.5 billion in compensation.

Severe pollution Japan has experienced
BackgroundIn 1955, Japan’s economy experienced unprecedented growth. In the late 1950s and early
1960s, 8.8 % and 9.3 % annual economic growth figures were attained respectively. Heavy
industries and chemical industries grew at high rates due to increased investment in facilities
and exports from the private sector, as well as active public investment. Heavy and chemicalindustries emitted more potential pollutants per unit than other enterprises in general.
Processing in Japan of the products to be exported causes emissions of more pollutants in the-260-country than those commensurate to the end consumption of the products in the country. Also,
investment for pollution control measures was less, in contrast to the high speed of growth.
The enterprises’ investment for anti-pollution was rather small, i.e. only 3% (about ¥30
billion) in 1965, which is the first year for which relevant data is available. This is one of thefactors that caused severe industrial pollution in Japan.
Progression of water pollution
As the Japanese economy rapidly grew, water contamination became more serious at a highspeed. The Sumida River, for example, had clean water in which many kinds of fish lived in
the late 1940s through the 1950s. The river also served as a place of rest and recreation forpeople and provided a livelihood for fishermen. Since around 1955, however, the river it has
become a sewage laden canal in which fish could not live any more and emitted a malodorous
stench.
In those days, water pollution became serious mainly because of the effluents discharged fromfactories and business establishments. The effluents discharged by Honshu Paper Co.’s
Edogawa plant without any pre-processing caused severe damage to the fishing industry in
the Urayasu area in suburban Tokyo in 1958. The aggrieved fishermen entered into
negotiations with the company and petitioned the relevant governmental agencies yet failed toattain any resolution. Later, an event occurred where about 700 fishermen broke into thefactory and scuffled with police.
Severe damages from pollution
Minamata Disease, Niigata-Minamata Disease, Itai-Itai Disease, and Yokkaichi Asthma arecalled as the four major diseases caused by pollution in Japan. Yokkaichi Asthma is caused byair pollution, so it will not be referred to in the following pages.
(1) Minamata disease
Nippon Carbide Firm, one of the predecessors of Chisso Corporation, built its Minamata plantin 1908. Soon after, the plant began to discharge effluents into the sea nearby. In the early
1950s, massive fish populations were killed in the Minamata Bay while cats and pigs on land
died in madness inducing disorders.
In 1956, a report was made to the Minamata Healthcare Center in Kumamoto Prefecture that ahospital took in a patient who was suffering from a brain disease whose cause was unknown.
This was the first identified case of Minamata Disease. Minamata Disease is a toxic disease
which affects the nervous system and is caused by methyl mercury. The Chisso Minamata
plant was using non-organic mercury as a catalyst in the acetaldehyde manufacturing process.
The catalyst generated a slight amount of methyl mercury which was discharged into the sea.
It accumulated in fish through biological concentration. Heavy consumption of these fish
caused Minamata Disease in humans.
Similar symptoms were discovered in patients near the Agano River in Niigata Prefecture in
1960. This disease was called Niigata-Minamata Disease. In this case, the cause of the disease
was the methyl mercury disposed of by the Kanose plant of Showa Denko K.K. locatedupstream on the Agano River.

There were around 3,000 legally-certified victims of both Minamata and Niigata-Minamata
Diseases in total and the damages (to the health of the victims due to contamination of bottom
sediment, and to fisheries) are estimated to amount to ¥378.9 billion in total.
The Supreme Court decided that such diseases and damages were the responsibility of thenational and Kumamoto Prefectural governments because they neglected to enforce regulation(Minamata Kansai lawsuit case, 2003). Today, five damage suits are pending (filed by about
1,500 plaintiffs) demanding the relief of about 20,000 victims.
(2) Itai-Itai Disease
Itai-Itai Disease is a pollution disease that frequently occured in the watershed of the
Jintsugawa River in Toyama Prefecture. It became noticeable in the mid-1950s. The name“Itai-Itai” (Ouch! It hurts!) comes from the fact that patients of this disease suffer severe bone
pain and always cry “Itai, itai!” It was found that this disease was caused by ingesting rice orwater contaminated by cadmium over an extended period of time. Kamioka mining plant
owned by Mitsui Mining & Smelting Co., Ltd. upstream on the Jintsugawa River had beendischarging, without pre-processing, effluents containing cadmium after refining zinc, causing
the contamination of water and soil.
The Law Concerning Pollution-Related Health Damage Compensation and Other Measures
specified Itai-Itai Disease as one of the designated diseases to be awarded compensation for
medical treatment expenses, etc., to certified patients. The legally-certified victims amount to
195, and they are still increasing as of 2008. The damages, including those to health andagriculture, are estimated to amount to ¥50.7 billion.
How pollution diseases were addressed
The conflict between fishermen and the paper plant over the fishery damages caused byeffluents from the plant in 1958, as mentioned above, led to enactment of the Water Quality
Control Low and the Factory Effluent Control Law, which are called the “former two water
quality control laws”) in the same year.
These laws ordered the national government to establish water quality standards for public
waters designated by it and to impose regulation on factories’ effluent.
However, these laws were enforced in such a way that further problems occurred. First
problem is that the water area was designated after polluted. Second problem is that the laws
had another purpose: to harmonize the health of citizens and preserve the living environment
with industrial development, securing water quality to the point where the benefits ofvictimizing and victimized industries were in harmony. Accordingly, they were not sufficientfrom the point of view of pollution regulation.
As a result, degradation of quality in public waters became observed in other cities in various
districts as industrial development even after the former two water quality laws were enacted.
Growing momentum of citizens’ movements
Frequent occurrence of environmental problems attracted wide attention from common people,
leading to citizen movements.
-262-

In 1960, there were widespread protest movements, including citizen rallies and signature
campaigns against a petrochemical complex planned for the Numazu area of Mishima City,
eventually forcing the plan to be cancelled in 1964.

Efforts in overcoming pollution
Conflict between prevention of pollution and economic growth
When promoting anti-pollution measures, it is important to solve the burden of costs required
for mitigating/preventing pollution. In principle, such costs should be paid by the enterprisesthat generate contaminants. However, it was often stressed that the cost of anti-pollution
facilities did not directly contribute to production and would also be a burden to industries.
Therefore, anti-pollution measures were believed as a factor obstructing industrial
development in Japan where small and medium-scale enterprises accounted for the majorityof all enterprises. As a result, the Japan Pollution Control Corporation was established in 1965
as an agency specializing in aiding the cost for prevention of pollution.
Also in 1967, the Basic Law for Environmental Pollution Control was enacted under theconcept that individual and first-aid-type regulations as intended under the former two water
quality control laws were insufficient, and that it was important to declare the basic principles
of anti-pollution measures and to promote such measures comprehensively and uniformly.
The Law declared that the prevention of pollution was very important for securing the healthy
and cultural life of citizens, establishing the “polluter-pays” principle and the environmental
standards which served as administrative targets. The Law was superseded by the Basic
Environment Law enacted in 1993, which took over almost all of the contents of the former
Law.
“Pollution session of the Diet” and establishment of Environment Agency
The national government made active efforts in taking measures against pollution since the
Basic Pollution Control Law was enacted. Given the fact that the sections in charge of taking
the measures covered many ministries, the government established Pollution Control Officeheaded by the prime minister in July, 1970, to enforce the laws more powerfully. Under theleadership of the Office, new efforts were started in order to develop a legal system forpollution prevention.
In an extraordinary Diet session in 1970, pollution problems were front and center in responseto the then public demand for anti-pollution measures and high public interest in the problems.
This session of the Diet was called the “Pollution session of the Diet.” The national
government submitted fourteen bills, including an amendment to the Basic Pollution Control
Law and the Water Pollution Control Law, all of which were approved and enacted by theDiet. Those bills featured: (1) Deletion of a clause providing for harmonization with theeconomy. This clause was deleted to cast aside the public’s skepticism that the former laws
might have put priority on the economic development over pollution control measures; (2)Introduction of national-wide regulations instead of regulations only in designated areas andalso strengthening regulations by adding to the number of substances. This was applied to
Air pollution and water pollution control; (3) Strengthening the power and authority to local
governments. Substantially, all authority over business operators was delegated to local-263-

municipalities, and the provisions for additional regulations were made to reinforce theauthority of the local municipalities.
In addition, the Pollution Control Office was resolved developmentally, with the Environment
Agency established in July, 1971.
New system of pollution control measures
The Water Pollution Control Law was enacted superseding the former two water quality laws,
after they were reflected upon. The Law may be summarized briefly as follows: (1) The Law
aimed to prevent contamination of public waters, thus protecting citizens’ health andpreserving their life environment, by regulating the effluents discharged by factories andbusiness establishments into public waters; (2) The regulation covered the effluentsdischarged by the factories or business establishments having specific facilities, which might
be specified not only in the manufacturing industries but also in any other industries; (3) The
standards for effluent regulation covered all the public waters from the viewpoint of theprevention of water contamination in advance, and, if the standards were considered to be
insufficient for any public waters, a prefecture might issue an ordinance adding stricter
standards; (4) To ensure compliance with regulation, the Law provided requirements for thereporting of the installation, etc., of the specified facilities, the issuance of orders to change
the plan reported, the issuance of orders to improve the waste water treatment processing
method, and so on. In addition, the Law provided a direct penalty system in which any
violation of the effluent standards would result in immediate punishment; (5) The Law
provided that a governor of a prefecture could order a factory or business establishment to
reduce the volume of effluents discharged into the public waters or to take other measures if
contamination increased due to exceptional drought or other reasons; (6) The Law obligated
the governors of prefectures to vigilantly monitor the levels of contamination in public waters
and to make this information available to the public.
To enhance the anti-pollution system, the staff of municipalities in charge of pollution
prevention were increased (from about 300 in 1961 to about 12,000 in 1975, (a 40 foldincrease) and the budget for pollution prevention was also increased. (¥73.3 billion of thenational budget in 1970 to ¥333.1 billion in 1975, that is about five fold increase). In 1972,
1,426 orders for improvement and 6,554 administrative directives were given to persons who
violated the Law or regulations. But the direct penalty was imposed on only 13 violators,
which was a rather small number. This shows that the administrative measures such as orders
and directives, were adopted as final measures to enforce the anti-pollution regulations.
Efforts made by pollution generating enterprises(1) Anti-pollution managerial system
Many of the factories obligated to comply with effluent regulations had no satisfactory system
to prevent pollution. Accordingly, the Law Concerning the Improvement of Pollution
Prevention Systems in Specific Factories was enacted in 1971, obligating those factories toestablish a committee with experts in prevention of pollution.
(2) Pollution Control Agreement
These days, more and more enterprises, municipalities and citizens’ organizations are entering
into Pollution Control Agreements, which provide stricter regulation standards than the-264-government’s, on-the-spot investigation, liability without fault, etc. The conclusion of suchagreements is encouraged partly by the fact that an enterprise experiences difficulty inoperating its factory without getting consent from the community as to location, and it can
avoid unwanted protests by entering into such agreements.
(3) Increase in investment for anti-pollution measures
The enterprises’ investment for anti-pollution measures increased substantially between 1967
and 1975 due to the long-term and low-interest fund that was made available by the Pollution
Control Corporation or other related institutions, and that favorable tax policies were put into
practice, including reduction of the fixed asset tax on anti-pollution facilities, reduction of thedepreciation period, etc. (Table 1).

Among the investments in facilities made by enterprises, the revision of production processes
and reuse of industrial water to reduce effluent, made radically substantial contributions tocleaner water, more so than the contribution made by improved effluent processing
technology at the so-called “end of the pipe.”
Both anti-pollution investment and the ratio have declined since 1976. The reasons may
include the fact that the measures taken by enterprises to comply with anti-pollution
regulations have advanced, reaching a plateau. This fact shows that anti-pollution investment
is not necessarily required infinitely.

Environmental restoration
The Sumida River flowing through central Tokyo had 60 ppm of BOD at one time because ofincreased effluents from factories and houses as mentioned earlier. It was said that therecovery of the original state of the river before the contamination might be impossible. Yet
today, the river has been returned to life and became the “Face of Tokyo” by means of theregulation on effluents from factories, improved sewage systems, dredging of bottom
sediment, and the introduction of cleaning water. In other districts as well, water quality has
been improved substantially, achieving environmental standards at high achievement rates
with the exception of some lakes, swamps and closed sea waters.

-265-Conclusion
One of the lessons Japan has learned is that the earlier the anti-pollution measures are taken,
the better the result (Table 2). Once damages are incurred, they require costs for compensation,etc. Taking preventive measures is much more economical as shown in the table below.

Today, Asian countries are achieving noticeable economical growth. It is desired that they
may not go through the same experience as Japan has, but overcome the problem ofenvironmental degradation, and take measures against global warming, a new issue as well.
For that purpose, Japan has set up the “Clean Asia Initiative,” and also will continue topromote the WEPA which is included in the initiative.
