Song Hau Surface Water Plant – Phase One

Song Hau Surface Water Plant – Phase One

In response to the critical problem of water cleanliness and security in the Mekong Delta, AquaOne Hau Giang has created a clean drinking water supply and wastewater treatment plant that is among the most advanced facilities in Vietnam. The company has invested more than 1,900 billion dong in 15 hectares of land for the first phase of the industrial plant, which will provide 100,000m3 of water per day to both residents and corporations. Once the second phase is constructed, the capacity will increase to between 500,000 and 1,000,000m3 of water per day.

Future plans call for even greater expansion, as AquaOne Hau Giang’s ambition is to become the major water supplier for such provinces as Can Tho, Soc Trang, Bac Lieu and Ca Mau. EDGE certification dovetails well with the company’s ambitions to elevate the living standards of the Vietnamese people by providing a reliable water supply in the most sustainable manner possible.

Phase One of the Song Hau Water Treatment Plant has received final EDGE certification from SGS Vietnam. While the complex also includes a green dormitory for workers, numbers in this project study are reflective of the light industry portion of the complex.
