2. OUTLINE
• WASTE WATER IN HOCHIMINH CITY
• DONG DIEU PUMPING
• BÌNH HƯNG TREATMENT PLANT

3. OVERVIEWS OF WASTE WATER IN HOCHIMINH CITY
• Water consumption per capita: 150 l/day
(source: JICA project for sewage planning in Hanoi)
• Total discharge in Ho Chi Minh city: 876,170 m3/day
• 83 hospitals, 26 medical centres - Discharge: 17,000 – 20,000 m3/day
• Total discharge from industrial zones/parks: 400,000 – 500,000 m3/day
• From Domestic: 300,000 m3/day.
(source: 2009, PCD project for building the wastewater pollution control action plan in Ho Chi Minh city)
• Wide range of wastewater . (Industry, domestic, hospital)
• Seprate and combine waste water system.

4. OVERVIEWS OF WASTE WATER IN HOCHIMINH CITY
• Domestic wastewater treated: less than 10%
• Only 30% of the industrial zones/parks have centralized wastewater
treatment systems.
• Can only treat certain pollutants at certain concentration limits. Eg: pH,
BOD, COD, SS, colority, nutrients. (satisfy column A and B of TCVN
5945:2005)
• Planning a system of 9 wastewater treatment plants (one has already
been in operation, 3 are being prepared for construction).
• Building wastewater treatment systems in large hospitals
• Improving centralized wastewater treatment systems of industrial parks
(equipping automatic monitoring system)

7. ĐỒNG DIỀU PUMPING STATION
• Pumping waste water from main sewage at Tàu Hủ - Bến
Nghé - Đôi - Tẻ Channel to Bình Hưng Waste Water Treatment
Plant
• Capacity:
- Phase 1: 133.3 m3/minute (192,000 m3/day) by three
underground pumps
- Phase 2: 400 m3/minute (576,000 m3/day) (will be
installed three more underground pumps)
