Ho Chi Minh City Environmental Sanitation (Nhieu Loc-Thi Nghe Basin) Project
 
The Ho Chi Minh City Environmental Sanitation Project will lead to sustainable improvements in public health, and the well-being of the city's population, through improved reductions in wastewater pollution, and in flood occurrences, as a result of institutional efficiency in the management of drainage, and wastewater services.

The two components are:

1) Construction of the Nhieu Loc - Thi Nghe wastewater interceptor, to divert dry weather wastewater flows to the screening/pumping facility. In addition, combined sewer overflow structures will divert wastewater flows into the interceptor during dry weather. However, to mitigate the accumulated, odorous waters from the canal during rising tides, a canal flushing mechanism will be installed, drawing canal waters to the sewage interceptor, through withdrawal chambers located in the canal embankment, operated through automatic modes controlled from the pumping station. This pumping station will have hydraulic capacities, and is located at the confluence of the canal, and the Saigon River, with a river outfall discharge.

2) Drainage works to replace, and extend combined sewers to reduce overflows of storm-water, and wastewater. Includes dredging works for sludge transportation and disposal; cleaning inspection of secondary sewers; and, construction of tertiary sewers. Equipment will be procured to support institutional strengthening, and maintenance functions.
