Authorities in Hanoi are drafting a water drainage plan with a vision through to 2030 in order to deal with the severe flooding the capital regularly faces.

The plan is expected to be completed in the fourth quarter of 2011 before being submitted to the Government for approval.
Under the new plan, Hanoi will focus on water drainage in the city centre, satellite urban areas and suburbs.
Currently, most of the city’s water drainage systems are heavily dependant on irrigation systems.
At present, waste water from the inner city is discharged into the Red River via the Yen Son pumping station, but more rivers, including Tich-Thanh Ha, Ca Lo, Nhue, and Day, will be connected to the drainage system under the new plan.
The city is forecast to discharge over one million cubic metres of waste water per day by 2020, and nearly 1.4 million cubic metres of waste water per day by 2030.
It targets to collect and treat 90% of the waste water by 2020 and all waste water by 2030.
