Pledge to clean up polluted city waters

NEARLY 2,000 kilometers of waterways have been identified as polluted, said the head of the city’s water authority.

The waterways, identified by remote sensing and satellite technologies, would be all cleaned up by the end of the year, said Bai Tinghui, director with the Shanghai Water Authority.

The clean-up campaign would include dredging dried watercourses and demolishing illegal structures along riverbanks.

This had begun on waterways together totaling 1,279km kilometers — with many poultry raising and polluting factories being removed from these rivers and creeks.

An additional 477km of polluted waterways, mostly hidden beneath villages and farmland, had been found via a “blanket search” by spectrum sensing and satellite photography, said Bai.

The high-tech sensing technologies, along with professional drones, would be used frequently in future to monitor the clean-up campaign and to prevent the waterways from being polluted again.

The city government has appointed local officials, from vice mayors to district directors, as “river chiefs,” charged with cleaning up polluted waterways and overseeing long-term sustainability. A total of 1,169 river chiefs had been appointed citywide, Bai said.

The number would rise to 5,000 by the end of June. Local residents were encouraged to monitor how the river chiefs were performing through the city’s 12345 hotline.
