Rainwater to get a cleaning

AUTHORITIES hope to make Shanghai's rivers cleaner and healthier by building a huge pipe system under Suzhou Creek that would collect rainwater to be purified before being drained to the rivers.

The Shanghai Water Bureau said such a system, now under discussion, would cleanse rainwater from throughout the city that now drains directly into the waterways.

"The plan has been on a strategic phase," Ma Yuandong, director of the drainage department of the bureau, said yesterday.

"It will largely help increase the water quality of the city's rivers," he said.

Ma said rainwater drainage contains a lot of polluting materials.

The city's rainwater would first be drained to the pipes under Suzhou Creek, which are to be 19 kilometers long and 9.2 meters wide.

The water would then flow to the city's sewage works to be purified before finally going to the rivers, Ma explained.
