Canal to boost flood control

CONSTRUCTION on a canal will start in Changning District at the end of the year to improve flood control in Changning and Minhang districts, local water authorities said yesterday.

The nearly 5-kilometer canal will be able to deal with one-in-20-year violent rainstorms. The 760 million yuan (US$11 million) project is expected to last 18 months, according to the project's investor, the Shanghai Water Project Investment Co Ltd.

Starting from Suzhou Creek, the canal will follow the Outer Ring Road to Xiajia Creek N. in Changning. It will also connect Xiajia Creek N. with Xinjinggang Creek. Eight bridges will be built over the canal, said the company.

Changning and Minhang districts have weak drainage systems and for a long time, as water has easily collected on the streets during rainstorms.

In August last year water took more than seven hours to drain away in Changning after a shower. In 1999, a rain spell during the plum rain season flooded Hongqiao Airport and the Shanghai Zoo.

"It's necessary to drain the collected water through a new canal," said company official Lu Jia. "With the canal, the collected water will drain faster than before, and the ecological environment of the area will improve."

The Shanghai Water Bureau said it will landscape both sides of the canal.

"We have invited experts to study the environment there and design pavement along the canal," said Hu Xin, an engineer with the bureau.

Bureau officials said it will also ensure the safe operation of Metro Line 2 and the Hongqiao transport hub during construction.
