A back-up source for tap water is now being created at the Taipu River in the Qingpu District for residents whose water currently comes from the Huangpu River, just incase the Huangpu River becomes polluted, city water authorities say.
The project will involve six water intakes linked by pipelines along the Huangpu River in Qingpu, Sonjiang, Jinshan, Fengxian and Minhang distracts, so that any one of them can be closed “in event of pollution”, Shanghai Daily reports.
A new reservoir connecting to the intake pipes will also be built in Qingpu near the Taipu River, where from residents can use the water supply directly.
The Huangpu River, currently one of Shanghai’s main sources for water, is facing great pollution risks.
“The Huangpu River has many pollution risks, such as upstream pollution, local waste water discharges and cargo ships,” a water authority was quoted as saying in the Daily.
And dead animals! Don’t forget the dead animals.
Studies show that Shanghai will face a water shortage if population continues to grow.
The current capacity of Shanghai’s water supply is around 16 million tons per day, enough to supply 26 million people. However, the city’s population is meant to reach 30 million within the decade, raising the demand to 18 million tons per day.
By 2015, water authorities say that Huangpu will only contribute to 30 per cent of the city’s drinking water, the rest provided reservoirs of the Yangtze River.
The new Taipu water system is projected to be completed by 2017.
