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

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)
BÌNH HƯNG TREATMENT PLANT OVERVIEW
