HA NOI (VNS)— Ha Noi is installing street drainage systems in 20 new flood areas which appeared when tropical storm Bebinca dropped 96mm of rain at the weekend.

Nguyen Le, general director of the Ha Noi Water Drainage Company, said the latest flood areas were Pham Van Dong, Linh Nam and Nguyen Xien streets, which were new urban areas that had been developed without proper drainage or sewerage.

In Ha Noi, storm water and sewage merge to run through the same drains and pipes.

As a result, Le said, canals and storm water/sewerage drains would be built and dredged so they would ensure the fast passage of effluent and storm water to pumping stations.

Meanwhile, company workers would be sent out to flood-prone areas during heavy rain to pump water out of the streets, he said.

These measures had already helped locations such as Thai Ha, Thai Thinh, Ngo Thi Nham, Nguyen Cong Tru or Nguyen Luong Bang streets, which used to be inundated but were kept flood-free in the latest storm.

The area's 300 key pumping stations had a total capacity of 4.1 million cu m of water per hour, coupled with another 300 or so district pumping stations, revealed deputy director of the city's Department of Agriculture and Rural Develoment Ha Duc Chung.

This was enough to deal with heavy rain, he said.

Careful co-ordination of these pumping stations was necessary to take full advantage of their capacity, he said.

Nevertheless, pipelines and canals to the Day, Nhue, La Khe and Thiep rivers still needed improvement.

Do Duc Thinh, director of the Municipal Flood, Storm Control and Dyke Management Department, said workers had been allocated to important dykes along the Duong River.

They are located in the districts of Long Bien, and the Dong Anh and Hong River in districts of Tu Liem and Hoang Mai, where landslides and fissures had occured in earlier rainy seasons, he noted.

Meanwhile, the city would focus on improving the knowledge and skills of citizens, he said, especially in dyke areas, so they could protect themselves and ask for assistance from rescue teams when storms and floods occurred.

However, experts said the city still lacked a comprehensive and long-term flood prevention plan.

Nguyen Van Hung, a former headmaster of Civil Engineering University, said the city was dealing with flooding situations in a patchy way. — VNS
