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 Chaipattana
aerator, 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,
Study Visit, Seminar, Research and Study, Sharing technologyetc.
