Facing Water Shortage, Shanghai Scrambles to Stop Saltwater Flowing Into Reservoirs

Shanghai has taken emergency measures to secure its water supply, as saltwater contamination has forced two major reservoirs to temporarily stop supplying water to the coastal city’s 25 million residents.

Qingcaosha and Chenhang reservoirs at the mouth of the Yangtze River have seen repeated saltwater inflows since the first half of September, causing them to take measures to prevent further intake to ensure water quality, according to Shanghai water authorities. At present, no water for either residents or companies may be drawn from the reservoirs, which are major potable water sources.
