The capital city plans to spend more than 116 trillion VND (5.5 billion USD) for upgrading its urban drainage system in a massive project set to be completed in 2030, according to Nguyen Van Khoi, Vice Chairman of Hanoi People's Committee.

Khoi made the comment on July 11 after the committee approved the plan. The funding for the project will come from Official Development Assistance (ODA), the State budget and bonds.

The plan aims to minimise surface water pollution and areas prone to flooding by 2015, with priority given to the inner city and the outlying districts of Long Bien and Ha Dong.

Work will be carried out to upgrade the sewerage system in Hoan Kiem, Ba Dinh, Dong Da and Hai Ba Trung districts to accommodate rainfall of up to155mm of rainfall per day.

Larger lakes that are able to accommodate large inflows of rainwater will be renovated. Meanwhile sewage pumping stations at Yen So, Bay Mau, Kim Lien and Truc Bach areas with capacity of 220,000cu.m per day will be upgraded to ensure waste water from inner districts meet environment standards before being discharged into the Hong (Red) River.

For the 2016-2020 period, a comprehensive drainage system will be built for the southern Hong River and Nhue River region to handle rainfall of 155mm per day.

Sewage systems in residential suburban areas are also scheduled to be completed during this period. Existing lakes are planned to be renovated while new reservoir lakes will be built in some areas.

A network to collect waste water from inner city and industrial areas will be established and more waste water treatment plants will be built in Yen Xa, Phu Do, west of the Nhue River , Ha Dong and Son Tay.

The project will operate under build-transfer (BT), build-operate-transfer (BOT) or public-private partnerships (PPP).-VNA
