JICA Master Plan (27 zones)
In 2011, Bangkok in collaboration with
JICA has proposed a 30-year master plan
for Bangkok to construct the wastewater
treatment . The construction area is
divided into 27 areas of wastewater
treatment cover 80-90% of total wastewater generated in

Treated Water Reuse
• In 2015, ~6% of treated water is reused for several purposes
such as planting, cleaning the road and market
9
Sludge for Land Application
Thonburirom Park
Sirikit Park
• Digested Sludge from WWTPs used as raw material for
composting and then mainly provide to BMA public park
• In 2015, about 13,150 m3 of sludge compost has been used
10
Challenges and Solutions
• “Public Private Partnership (PPP)” should be implemented for the
future projects in order to solve the financial problems
• “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
