SHANGHAI is launching a series of assessments to check water quality in Suzhou Creek as part of the fourth round of an anti-pollution campaign.

Shanghai Water Authority said the campaign aims to clear polluted water — currently rated Grade 5 plus — on the creek’s main stream by 2020 and on its branches by 2021. The campaign will also reinforce levees along the creek and improve shipping channels.

By the same date, an ecologic sightseeing corridor will be completed along the creek and it will become a showcase for the city’s haipai culture — the unique Shanghai culture that combines traditional Chinese and Western culture — and an open recreational area.
