According to Luong Minh Phuc, Director of the municipal Transportation Works Construction Investment Project Authority, this expansion represents the largest investment of the project, with a total budget of approximately 11.3 trillion VND (454.27 million USD), sourced from Japanese ODA loans via the Japan International Cooperation Agency (JICA) and domestic reciprocal funds.
The expansion will enable the Binh Hung plant to increase its treatment capacity to 469,000 cubic metres of wastewater per day, up by 328,000 cubic meters compared to Phase 1. This will allow the city to manage wastewater across a wider area of over 2,500 hectares, serving a population of around 1.8 million people.
Phuc explained that wastewater is collected from Districts 4, 5, 6, 8, 10, 11, and Binh Chanh district, and then transported via a sewer system to the Dong Dieu pumping station in District 8. At this station, it undergoes preliminary screening to remove sand and debris before being pumped to the sedimentation tanks at the Binh Hung plant for initial filtering, followed by treatment in other tanks. The plant uses a biological treatment process without chemicals, contributing to reducing pollution in the Tau Hu-Ben Nghe-Doi-Te canal system.
Following the completion of Phase 2, the project will proceed to its final phase, expanding the wastewater treatment coverage by an additional 1,600 hectares, encompassing areas in Districts 7, 8, and Nha Be district, to serve a population of approximately 900,000. Once this phase is completed, all domestic wastewater from the Tau Hu-Ben Nghe-Doi-Te canal basin will be collected and treated to meet standards before being discharged into the environment.
In addition to the Binh Hung plant, HCM City has two other wastewater treatment plants. Currently, the southern economic hub's total capacity for urban wastewater treatment is about 40% of its daily discharge volume./.
