The quality of water supply resources for HCM City has declined due to water pollution in the Dong Nai River, experts have warned. “Most of the water supply resources for the city come from the Dong Nai River, but the water quality has declined due to economic development and urbanisation along the river,” according to Dr. Nguyen Van Nga of the municipal Natural Resource and Environment Department. In 2015, the city needs 2.7 million cubic metres for daily usage and business production every day. The figure is expected to rise to 3.55 million cubic metres by 2025.

HCM City is the biggest city in Viet Nam, with a natural area of nearly 2,100 square km and a population of around 10 million. The city’s pace of urbanisation has been the fastest nationwide in recent years. From 1999 to 2009, the population increased annually by 3.5 per cent, and doubled between 1989 and 1999, 3.7 times higher than the 1979-1989 period. The increase in population and economic growth has led to serious pollution in waterways. Thus, water from the Dong Nai River and from Sai Gon – Dong Nai River, and within the city, has seen a severe decrease in quality.
