VISION

Achieving good and healthy environment tosupport environmentally sustainable
development in South Sumatra

MISSION• Pursuing better quality of environment, including

water, air and land cover•Controlling the increase of Green House Gas Emission•Enhancing Capacity Building of Environmental Agency

on Managing Environment

Activities on Managing and Controlling Environment

Managing Environment:
1. Assessing environmental performance on 100companies. Those have to comply government
regulations on controlling environment.
2. Educating
peopleonenvironmental
awareness.
3. Monitoring Air and Water Quality for Basis
Data on development.
4. Constructing facilities of integrative domestic
wastewater treatment in three points.

Communal Wastewater
Treatment Plant

BACKGROUND

People who live near
the river, do washingand bathing.

Water are mostly polluted
by Fecal Coli and otherchemicals fromwastewater discharge aswell as fertilizers… (referto data)

7

Alongside Musi
River, People havefloating toilets fordefecation andurination
Traditional group,
who do not havesufficientknowledge on
healthy sanitationand have
economic
constraints, have
one toilets for one
familyCommunal Wastewater Treatment Plant• Municipal Government construct three
Communal Wastewater Treatments Plants;
located in Jayalaksana, Prajuritnangyu, andKasnariansyah.
• The areas are highly populated. Kasnariansyah
is noted about 1000 people live in rented flat.
In Jayalaksana and Prajurit nangyu there areabout 2000 people each location (slum areas)8Technology : Anaerobic Baffle Reactor

BENEFITS :• Low cost operation system• Bio-gas can be used for cooking and electricity• Ecological friendly waste (minimum impact)• Healthy sanitation• Economic generation (payment service –affordable)• Sustainable development because water isless deteriorated.

Notes:
a. Distribution of Wastewater treatment and discharge in South Sumatra (Riset Kesehatan Dasar, Kementrian Kesehatan RI, 2010):•
49,6% septic tank (individual)
1,7% Communal Wastewater Treatment Plant (aerobik)•
26,4% direct dumping to environment
2,4% to pond/rice field•
16,6% wet latrine
2,2% to beach•
1,1% others.
b. Degradable Organic component = 40 gram/(person.day) = 14,6 kg BOD/cap.yr (Table 6.4 IPCC 2006 Volume 5 Asia, Middle East andLatin America.

Challenges :• Institution for managing installation.
• Public awareness (Public Participation)• Budget for maintenance.
• Less coordination among stakeholders, people,local government and its up-line institution• Less studies for development this method• There are 353,975 ton CO2 eq (produced fromMethane in individual Septic Tank)

Conclusion• Communal Wastewater Treatment Plant haveto be developed in South Sumatra, especiallyin Highly Populated areas• As complexity problems on environments, weneed to encourage people, other groups(academia and NGO) to participate on
managing environment.
