HA NOI – Ha Noi needs over VND14 trillion (US$666 million) for its urban drainage system until 2015, according to recent reports.
The money, of which VND7.9 trillion ($476 million) is expected from Official Development Assistance (ODA), VND1.3 trillion ($61million) from socialised capital and the remaining VND4.9 trillion ($233million) from State budget, is required for 13 drainage projects in the city.
Accordingly, the sector will fix current flooding points in inner districts by upgrading the drainage system with a capacity of 310mm of rainfall per day while they improve the drainage system at 20 lakes, renovate 26km of local canals, build 25km of new sewers, 11 river bridges and 20km of river roads.
In the Nhue River basin, west of the city, the sector would renovate and build three sewage pumping stations at Co Nhue, Dong Bong 1 and Dong Bong 2 to address flooding problems.
The sector said projects also included the building of reservoir lakes, pumping stations and canals in suburbs of Ha Noi as well as the renovation of drainage facilities, adding that Ha Noi would replace 80 per cent of its drainage works done by hand with modern machines by 2015.
According to Nguyen Le, director of Ha Noi Drainage Company, the city's old sewage system is strained by its growing population. The city's current sewage system can only handle up to 50mm of rainfall per day, but during the wet season, the city can experience rainfall of 150mm per day.
The director said the inner city struggled with 21 flooding points such as Thai Thinh, Thai Ha, Van Mieu and Tay Son.– VNS
