Cleaner tap water is in the pipeline - officials

LOCALS can look forward to cleaner drinking water beginning this summer, when the under-construction Qingcaosha Reservoir project wraps up its final pipeline adjustment and starts functioning.

Most of the construction of the main body of the reservoir as well as three main pipelines in downtown has been finished.

The information came from city government, which held a press conference yesterday with updates on 84 key projects around the city.

When the 17-billion-yuan (US$2.49 billion) reservoir project is up and running in July, it will serve better-quality tap water to about 10 million Shanghai residents, or 80 percent of the city's population living within the Outer Ring Road, officials said.

The city has been troubled by a shortage of quality water supplies. Tap water in Shanghai now only meets China's third-highest quality standard.

The project, which began in November 2007, is expected to supply water that's up to the second-highest quality level after processing. Visitors to the 2010 World Expo will drink the water from the reservoir after it's purified, according to Shanghai Water Authority.

Two cross-river pipelines, connecting the reservoir on the city's Changxing Island to Pudong New Area, were completed early February. The pipes can carry 7 million cubic meters of water a day.

Four pipelines, nearly 200 kilometers long, in downtown city will connect with the cross-river pipes at what will be Asia's biggest pump station. The Pudong pump station, Wuhaogou, will start running equipment testing in April.

Downtown pipes

The downtown Yanqiao and Jinhai pipelines will be able to carry water by July.

The Lingqiao Pipeline will be up by December.

The fourth downtown pipeline, Nanhui Pipeline, will start construction in July and is scheduled for completion next year.

The construction of another pipeline on Changxing Island will begin in August.

The 70-square-kilometer reservoir sits next to Changxing Island and will draw water from the Yangtze River.

It will be 10 times bigger than Hangzhou's West Lake.

At present the Huangpu River is Shanghai's major source of water, with 80 percent of tap water taken from the meandering body of water.

Upon completion of the reservoir, water from the Yangtze will supply up to 50 percent of the city's tap water, authorities said.
