Overviews of WEPA While the Asian economy has shown remarkable development, serious water pollution
problems have been occurring in this region.
 In order to solve water environment problems in Asia and achieve sustainable development, it
is essential to enhance information, knowledge and systems on water environment, andimprove water environment governance.

 At the Third World Water Forum (2003), the Ministry of Environment, Japan proposed anetwork of government officials in Asia (WEPA).

WEPA partner countries (13 countries)
1. Democratic Socialist Republic of Sri Lanka (Sri Lanka)
2. Federal Democratic Republic of Nepal (Nepal)
3. Japan (Japan)
4. Kingdom of Cambodia (Cambodia)
5. Kingdom of Thailand (Thailand)
6. Lao People's Democratic Republic (Lao PDR)
7. Malaysia (Malaysia)
8. People's Republic of China (China)

9. Republic of Indonesia (Indonesia)
10. Republic of Korea (Korea)
11. Republic of the Philippines (Philippines)
12. Socialist Republic of Viet Nam (Viet Nam)
13. Union of Myanmar (Myanmar)2

Goal and activities
 Aim to contribute to improving the water environment through strengthening water
environment governance in Asian region, by establishing a cooperative systemamong government officials involved in water environment management in the Asianregion, and implementing initiatives such as collecting and disseminating
information, developing human resources and capacity, and developing relevant
systems in WEPA partner countries

The previous WEPA workshop
WEPA Workshop on Industrial Wastewater Managementin September 2017 in Jakarta, Indonesia(1) Shared overview of industrial wastewater regulations• The existing types of industrial wastewater quality standards and theiroutlines (basis for regulation, target industries, target pollutants)• Industrial wastewater quality monitoring methods• Challenges in monitoring• The situation of compliance regarding industrial wastewater quality
standards and industries which face challenges in compliance(2) Shared situation and challenges for the problematic industries

and countermeasures• Overview of the problematic industry and impact to the environment ofwastewater emitted from the respective industry• The reason for non-compliance of the respective industry and theproblematic pollutant(s)• Current mitigation measures and the problems therein• Technologies and needs for addressing the challenges

Identified facts
Establishment of Effluent Standards in WEPA Countries
 Effluent standards are established in all WEPA countries except Myanmar,

6

Identified facts
Compliance rate of industrial effluent standards
 There are big differences in the compliance rates between WEPA partner countries.
 In many countries, the compliance rate of industrial effluent standards is not high,and the compliance rate is not accurately recognized by government agencies.

No data or not published(source: WEPA Outlook 2018, pp.28-29)

7Issues and measures based on efforts up to the 3rd Phase There are two main reasons why water environment conservation in Asian region
has not been achieved - one is that not only the effluent standards are not complied
with, and the other is that wastewater quality control alone is insufficient.
 Measures need to be taken according to each factor.

Main issue
Water environment conservation in the Asian region has
not been achieved.
（Env. water quality standards have not been achieved.)
Domestic and industrial effluent standards are
not complied with.

Wastewater quality control
alone is insufficient.

Effluent standards are notappropriate.

Measures

Discussion points on pollution load control• What is the background for introducing total
pollution load control system (in addition to theexisting concentration-based effluent standardsystem)?
• What are the lessons learned from the specificcases implemented in WEPA countries?
• What are drivers and barriers for introduction
and successful implementation of a total
pollution load control system?

Discussion points on wastewater quality control• What is the latest status of compliance withindustrial effluent standards in your country?
• What are the main reasons for non-compliancewith industrial effluent standards?

Overall discussion• What measures and activities are needed to ensure a high ratio ofcompliance with industrial wastewater effluent standards?
Examples of measures required for complete compliance with regulations
 Clarification of roles and authorities of central and local governments
 Complete regulations for businesses (notification, measure and log pollution
status of effluent, on-site inspections), penalties, order remedy, administrative
directions, etc.
 Appropriate enforcement and operation of the effluent standards• Enforcement and application of more stringent effluent standards in cases,
where national effluent standards and their scope are insufficient due tonatural and social conditions• Application of temporary effluent standards when compliance with effluent
standards is technically difficult

 Review of appropriateness of existing effluent standards and improvement
 Introduction of a total pollution load control system, when conventional water
quality control measures through effluent standards alone is insufficient.
