Song Duong River Surface Water Treatment Plant

Song Duong River Surface Water Treatment Plant

EDGE Advanced

In a city that faces frequent shortages of clean water, the Song Duong River Surface Water Treatment Plant provides a solution. The plant is part of Hanoi’s vision to supply clean water to all citizens by 2030. With the first phase of the plant already in operation, the city has several expansions planned that will significantly increase the capacity of the plant over time, ultimately providing water to nearly three million people. The plant filters water from the Duong River, then treats and funnels it into the largest water supply network in Vietnam, totaling more than 70 kilometers of pipes.

Hanoi hopes that this new water treatment plant will contribute to the development of the city and improve the quality of life for its residents. To ensure sustainable development, the city built the plant’s dormitory facilities to conserve natural resources. These green features also provide economic benefits, reducing operational costs by nearly half. The Song Duong River Surface Water Treatment Plant has received final EDGE certification from SGS Vietnam.
