City will build its largest sluice gate

CONSTRUCTION of the city's largest sluice gate started yesterday in Fengxian District to improve flood control capacity in that area and relive flooding pressure of the Huangpu River.

The sluice gate, a 290 million yuan (US$43.58 million) project, is being built on Jinhuigang Creek, which is 21.8 kilometers long and links the Huangpu River to Hangzhou Bay.

The gate will be able to resist typhoons with wind speeds up to 119 kilometers per hour and extremely high tides, which generally occur once every 200 years.

Construction is scheduled to be finished before the flood season in 2012, the Shanghai Water Authority said.

The new gate will replace an older one. Built in 1980, the old sluice gate can no longer meet flood control standards in the area, officials said.

Jinhuigang Creek has frequently burst its banks during tides in the past few years, inundating some areas of eastern and southern Fengxian. This has even threatened the Huangpu River's water level. The new gate will solve this problem.

Additionally, with a maximum drainage discharge capacity of 650 cubic meters per second, the new sluice gate may also be an important tool to regulate the creek's water and improve its ecosystem, officials said.
