Qingcaosha Reservoir has all Pudong covered

THE Qingcaosha Reservoir now has all of the Pudong New Area covered after the last two water plants were shut down.

The old Liutuan and Huanglou plants are no longer in service. Drinking water was being pumped from the reservoir to Changxing Island in Chongming County and into the Veolia water plant in Pudong from yesterday.

Tap water in downtown areas and Changxing and Hengsha islands is already supplied by the reservoir. About 70 percent of the city's population now gets its tap water from the Yangtze River, which is purified at the reservoir.

The water safety at Qingcaosha is secured through a comprehensive monitoring system to prevent any pollution inside the reservoir, according to Shanghai Chengtou Group, the operator of the reservoir.

With a total capacity of 438 million cubic meters, Qingcaosha is able to meet the city's water demand for 68 straight days without taking in any water from the Yangtze.

"Qingcaosha is a cleaner water resource and the water quality is more stable than that of the others," said Gu Jinshan, director of the Shanghai Water Authority.

Gu also said the wastes discharged by factories along the Yangtze River will not affect the water quality since the reservoir gets its water from deep inside the river. "Pollutants from factories usually settle along the banks of the river, while the water in the middle stretches of the river is of good quality as the Yangtze is capable of cleaning itself up," Gu said.
