Domestic 75% 20% 2. Industry 20% 75% 3. Agriculture 5% 300 Sampling Points in 165 major canals and 9 Sampling Points in Chao Praya River 300 Sampling Points

3 BOD (2016) BOD in major canals (mg/l) 0-4 mg/l (5 points) >4-10 mg/l (69 points) mg/l (93 points) mg/l (133 points) Most of Biochemical Oxygen Demanded (BOD) in major canals are around mg/l (133 sampling points). That s effect to the purposes of water use in Bangkok. DO (2016) DO in major canals (mg/l) Most of Dissolved Oxygen (DO) in major canals are very low (< 1 mg/l 121 sampling points). That s effect to the living organism in the canals >3 mg/l (70 points) 2-<3 mg/l (50 points) 1-<2 mg/l (59 points) <1 mg/l (121 points)

6 Improving water quality in the canals to reach the surface water standard Increasing recycling and sanitized reused water from 6% to be 10% for agricultural and industrial use Wastewater treatment project implementation by Public Private Partnership Saving energy equipment is installed to the wastewater treatment system Raising people participation Wastewater User Charge is the first priority for Bangkok

7 Improving water quality in the Canals by people in their communities Brain Storm Output Presentation

9 Principle of Wastewater User Charge in Bangkok Polluter-Pay-Principle Revision of the wastewater user charge regulation in 2004 by the BMA council Preparation of the fee collection The wastewater user charge system should be acceptable Managem ent 13.93% Maintenance 25.00% Material 1.88% Water Supply 0.18% Office Material 4.44% Wage 21.38% Electricity 33.19% No. of District 21 Area Coverage (m 2 ) Tung Kru Bangsue Chatuchak 8 7 Huai Khwang DusitPhaya Thai Dindaeng 2 6Ratchathewi Phra Nakhon Pom Prap Sattru Phai Samphanthawong Pathum Wan 1 Phasi Charoen Bang Rak 4Bang Khae 3 Nong Khaem Bang Kho Laem Sathon Rat BuranaYannawa Chom Thong 1.
