- Abstract:
- The Qingcaosha raw water system, located in the Yangtze River estuary, is responsible for more than 60% of raw water supply in downtown Shanghai. However, the Qingcaosha reservoir has been invaded by saline tides and limited water intake, due to continuous drought and successive impacts of typhoons in the Yangtze River basin since August 2022. In response, the upstream Huangpu River has provided emergency support to the Qingcaosha raw water system. Songpu Bridge pumping station enhances water supply efficiency by adjusting pump speeds under the maximum design water supply flow rate when raw water is switched to support the Qingcaosha system. The equipment guarantee and operation management measures, the water quality changes of Huangpu River, and the practice of optimizing water quality by adding powdered activated carbon during the emergency water supply period are summarized.
