City drains renovated ahead of heavy rains

SHANGHAI is gearing up for torrential summer storms by increasing the drainage capacity of the city's sewerage system, but challenges still remain, officials said yesterday.

After renovating drainage pipes on six roads in five districts across the city, Shanghai can drain out about 4,800 cubic meters of water per second - more than double the size of a standard swimming pool - in case of sudden heavy downpour, said Zhou Yu, deputy director of the drainage department of Shanghai Water Authority.

Authorities carried out repair work earlier this year on drainage systems under Harbin, Yangqu, Shandan, Pingliang and Hulin roads and Haijiang No. 2 and No. 4 roads.

"We changed some smaller pipes to bigger ones so that the water goes down faster," Zhou said. "The areas around the roads will also benefit as the flood waters will be drained out faster."

Zhou said they had also purchased eight more pump trucks and recruited 18 more teams to increase the mobile draining capacity.
