This is the third wastewater treatment plant to be built in Binh Duong with investment of over US$115.2 million. It is a sub-project of the World Bank-funded project to build water drainage and wastewater treatment systems in Di An town. Covering an area of 6.8ha in Tan Dong Hiep ward of Di An town, the Di An wastewater treatment plant is equipped with advanced technologies. Domestic wastewater taken from residential areas is deodorised and disinfected before being discharged back into the environment, contributing to protecting public health and the water resources in Dong Nai river basin. The project benefits roughly 40,000 people living in the wards of Binh An, Di An, Tan Dong Hiep, An Binh, and Dong Hoa of Di An town. Addressing the inauguration ceremony, Deputy Minister of Construction, Phan My Linh, highlighted the significance of the project, saying that it contributes to improving the local water environment and promoting socio-economic development in the locality.
