Sewage exits along Yangtze River to be mapped

The Ministry of Ecology and Environment, China's top environmental watchdog, has launched a campaign to comb the banks of the Yangtze River to map all sewage outlets and identify any that are unregistered.

Water quality monitoring will be done at all sewage outlets, and environmental officers will trace any pollution they find to its source. Tailor-made remediation measures will then be undertaken, the ministry said.

It also said the latest technologies, including satellite remote sensing, unmanned aerial and aquatic vehicles and intelligent robots will be brought into the campaign, which will last for two years.
