Work underway to prevent flooding

AS the seasonal typhoon threat level increases, Shanghai officials are stepping up efforts to prevent flooding.

Shanghai Flood Control Headquarters officials have identified 56 neighborhoods, low-lying roads, Metro stations and dikes across the city that are vulnerable to flooding, said Wang Mengjiang, executive deputy director of the SFCH.

“The headquarters have required district governments to reinforce flood prevention walls or take other emergency measures to protect vulnerable places before the typhoons come,” Wang said. Residential neighborhoods built before 2000 are among the most flood-prone places in the city.

They are likely to be flooded when precipitation reaches 50 millimeters per hour, Wang said.

SFCH officials will be on duty around the clock and pump vehicles are on standby to drain accumulated water during heavy downpours. For more extreme situations, plans are in place to evacuate residents, said Wang.

The city has over 400 major pump stations, 82 pump vehicles and over 100 flood prevention teams to protect the city.

Over 18 kilometers of dikes have been reinforced in preparation for the bad weather, according to SFCH spokesperson Zhang Zhenyu.

Meanwhile, construction has started on a new West Flood Prevention Project in the city’s western Jinshan, Songjiang and Qingpu districts.

High flood prevention walls are being built along rivers across outlying districts and more dams are being built.

The western part of the city will be able to withstand severe flooding after the work is completed. The walls, which will stretch over 200 kilometers, will be completed by the end of next year.

Meanwhile, two major flood prevention projects are underway — the nation’s largest deep-water drainage system, which runs underneath Suzhou Creek; and the Taihu Lake-Wusong River Flood Discharge Project, which will stretch about 120 kilometers between the lake and the river.

Most of the typhoons and rainstorms hitting the city are expected in late August and September, Zhang said.

Shanghai has been bracing for one of the severest flood seasons in its history since the plum rain season began this year.

The water level of the upstream Taihu Lake reached 4.87 meters, the second-highest level ever. This had a knock-on effect on the Huangpu River, which reached its second-highest level — 4.11 meters — in two decades.
