HANOI, June 10 (Engineering Daily) -- In the rainy season every year, Hanoi citizen is obsessed about flooding everywhere. Since the historic flood in 2008, Hanoi People’s Committee has invested to recover the flood. However, the more investment, the more city is inundated in the wide range.

There are many reasons that the flood in Hanoi becomes a “chronic disease”. The sewage water system at the central districts is overloading, and in the recent years, this system has been seriously injured. Moreover, the surface water drainage system such as pond and lake has been narrowed due to the whirlwind of urbanization. Or even in the new urban area, the plan and construction of drainage system lacks the synchronization. Overall, the mistakes mostly belong to the management agencies.

In 2014, talking about the flood, Mr. Nguyen Le, General Director of Hanoi Water Drainage One Member Ltd., some new sewerage systems have been completed, so Hanoi can reduce 8 heavy flooding points in total of 32 points. However, as recorded in the stormy rain on 25 May 2016, there were 36 submerged points remaining. Frankly speaking, although the city has invested the billions to upgrade the drainage system, the problems has not been solved completely.

According to the Hanoi Urban Sewage System Plan up to 2030 and a vision upward to 2050, Hanoi will need VND 116,417 billion for investment to prevent and control flood during next 20 years. The solution is a priority of the flood drainage areas. Accordingly, Nhue, Hong, Day and Tich Rivers which are in Hanoi region will be rehabilitated in order to increase the flood drainage capacity. Hanoi will build the technology of wastewater sludge treatment and collection, as well as sewage systems to protect pond and lake system being invaded by waste water.

Certainly, more than 10 drainage projects implemented by Hanoi Drainage PMU (belonged to Department of Construction) using preferential ODA loans are to improve the environmental sanitation in the capital city. However, many important drainage items during the investment and construction periods were postponed due to different reasons. Temporarily, to face with flooding, during each heavy rain, Hanoi Sewage Company assigns manpower and equipment to be on duty to open manhole, to pump water out for assistance of waterlogged discharge.

To deal with the flood control in Hanoi, the city cannot only pay attention to the rehabilitation and upgrade of drainage system, but also the plan of sewage system together with plan of land use, construction and transport.  And if the insufficiency of management is not cleared, the flood in Hanoi will last forever.
