Headstreams from Dianshan Lake, Zhujiajiao Town, Qingpu District, Shanghai 201700, China
Shanghai gets most of its drinking water from the Huangpu, and dumps most of its sewage into it (4 mln tonnes in 1990., only 4% of it treated in any way). As a result of pollution, the tap water must be heavily chlorinated. It is an average of 400 meters wide and 9 meters deep. It divides the city into two regions: Pudong to its east and Puxi to the west. Huangpu River is the largest river in Shanghai, with Suzhou Creek being its major tributary.
