Ho Chi Minh City (HCMC), economic capital of Vietnam, is facing growing problems that could put in jeopardy its development – rapid urbanization, urban traffic congestion, anthropogenic pressures on the environment and impacts on public health becoming more significant.
The Nhieu Loc-Thi Nghe canal was the main drain for untreated effluents from the catchment area: its quality parameters were similar to the one of raw sewage. In addition, the drains used to overflow under rainy conditions: areas including houses, roads, and other public areas, were regularly flooded with a mix of storm water and wastewater. Exposure to raw sewage and the presence of stagnant water dramatically increase the spreading of waterborne disease amongst the population.
In order to address the aforementioned issues, a USD 250 million investment project - namely the Ho Chi Minh City Environmental Sanitation Project (HCMCES) - was implemented under World Bank financing from 2001 to 2010.
Phase II of HCMCES Project (450 million US dollar project financed by the World Bank) aims at providing proper treatment to those effluents through the construction of a Wastewater Treatment Plant (WWTP) (1.5 million People Equivalent , 830 000m3/day by 2045) and an interceptor (8 km long and 3.2 meters diameter) under the canal. This the most important project of its kind and a first in Viet Nam.
