Shanghai will spend 120 million yuan (US$16 million) to upgrade
10 kilometers of sewage pipes next year to prevent streets from
being flooded in heavy rain, according to the Shanghai Drainage
Administration.
The project is part of plans to improve the city's drainage
capacity, which is scheduled to be nearly doubled in 2020 from this
year's level.
The pipes to be upgraded are within the Outer Ring Road where
the networks are decades old. At the moment they can't handle heavy
rain, resulting in flooded streets or underpasses.
A total of 20 sections of the drainage pipes will be replaced
with larger ones around one meter in diameter. The project will
coincide with road repairs.
The city's drainage capacity reached 2,370.5 cubic meters of
water per second this year, an increase of 10 percent from 2005,
covering 686 square kilometers, after new sewers were built and old
ones renovated.
The goal is to boost overall capacity to 4,148 cubic meters per
second by 2020.
