• To serve WWTP 100% of developed area in Bangkok

1. Policy Target

•Domestic WW(75%) and Agriculture(5%) are responsible by “BMA”

•Industrial WW(20%)responsible by Ministry of Industry

2. Institutional

• Construction cost sharing of Central Government and BMA vary between 75:25 to 40:60

• O&M Cost 100% by BMA

3. Financial• BMA

1. Onsite WWTP(Household) Regulation control2. Community WWTP (NHA)3. Central WWTP Control by BMA

4. Good Practices

• Capacity 1.12 mil m3/d• 45.5% of WW generation• Construction Cost 24,603 milB• O&M Cost 559 mil. Baht/year

Bangsue Education and Environmental Conservation Center

• The 1st underground WWTP of Bangkok with capacity 120,000 m3/day (2,000 m3/day treated by membrane technology and use for water fall in front of the building and supply to the park)

• Construction Year 2008 to 2014 and Construction Cost 4,732 million Baht from BMA (year 2008 to 2014)

• Education and Environmental Conservation Center (Meeting room, Exhibition hall, History room of Sewerage System and Water Quality Management and Environmental Library)

• Royal initiated project (the Chaipattanaaerator, and growing plant in the pond for wastewater treatment purpose)

Both Community WWTP and Central WWTP should be served to all developed area in Bangkok

• “Public Private Partnership (PPP)” should be implemented for the future projects in order to solve the financial problems

• “Collecting fee” is another source of fund for the operation and maintenance of wastewater treatment projects

• “Treated Wastewater” is the alternative water for using in some specific activities (6% of treated wastewater using for watering plant, cleaning the road, flushing system etc.)

• “People Participation” will pay an important role to improve the surface water quality

• “Energy Saving Technology” for Wastewater Treatment System should be studied and applied for solving global warming

• Wastewater Treatment Plant implementation and O&M are the good practice not only for engineers, scientists, students and people in Thailand but also in various countries especially in ASEAN countries

• Cooperation among experts, officials, administrators or policy markers in various activities, for example : Training Program, StudyVisit, Seminar, Research andStudy, Sharing technologyetc.
