All polluting sources have been removed from Shanghai's drinking water reservoirs, says the city's environment authority.
A report issued by the central government's environmental protection watchdog showed that by April, Shanghai still had six companies in Songjiang District discharging pollutants in forbidden areas.
According to China's anti-water pollution regulations, no sewage and waste discharge outlets should be built near drinking water resource protection zones.
Shanghai Environmental Protection Bureau told local media this week that all six polluters had been removed or had their operations suspended by July.
As a result, there are no more pollution outlets near Shanghai's drinking water reservoirs, the bureau said.
The six companies are Yexie Lime Plant, Shanghai Zhixin Rubber and Plastic Product Company, Shanghai Shangchuan Chuantian Steel Structure Company, Shanghai Huanshan Trading Company, Shanghai Dajiang Feed Company, and Shanghai Shipyard Company's Songjiang Branch.
Yexie Lime Plant was the last to be closed. The company pulled down two 40-meter chimneys on July 10.
The bureau said that protective fences have been built around the city's first-tier water reservoirs of Qingcaosha, Dongfengxisha, Chenhang and Jinze to ensure an improved management.
Some 415 pollutant discharge outlets near the city's second-tier water resource protection zones have been closed since last year.
The city authority also pledged that there would be no more constructions or projects near reservoirs that are not related to water supply and water resource protection in the future.
