One of the two projects covering 13ha in Thanh Tri district is estimated at JNY36.1 billion and the other covering 6 ha in Tu Liem district at JNY39.1 billion.

They aim to ensure wastewater treatment for five inner precincts and two outlying districts by 2017.

The station in Thanh Tri is designed to treat 135,000 cu.m. a day in the initial stage and to double its capacity in the second stage. The other one has daily capacity of 21,000 cu.m., which will increase by 3 or 5 folds in the second stage.

General Director of the Hanoi sewage company, Nguyen Le, said currently the capital city discharges an estimated 510,000 cu.m. of wastewater a day, including a large volume of toxic wastes from industrial zones and hospitals but only five to seven percent of the volume are treated by standards measure at two existing wastewater treatment stations.
