Shanghai Wastewater Treatment Plant, Xuhui District, Shanghai, China

The Shanghai wastewater treatment plant is located in Xuhui District, Shanghai, China, serving a population of approximately 160,000. This facility is part of Shanghai's extensive municipal wastewater infrastructure, which manages the city's domestic and industrial wastewater. As a plant serving a medium-sized agglomeration, it is expected to meet China's Discharge Standard of Pollutants for Municipal Wastewater Treatment Plants (GB 18918-2002), which mandates secondary treatment with nutrient removal for sensitive water bodies. The plant's designed capacity is 1.00 (likely in cubic meters per day or similar unit), indicating its scale. The treated effluent is discharged into the local water system, which ultimately drains into the Huangpu River and then the Yangtze River estuary, flowing into the East China Sea. This watershed supports diverse aquatic life and is critical for Shanghai's water supply and ecological health.

The plant discharges into the Huangpu River basin, which flows through Shanghai and joins the Yangtze River at its estuary before reaching the East China Sea. This coastal region supports important fisheries and migratory bird habitats. The Yangtze estuary is ecologically sensitive due to its role as a nursery for many fish species and its proximity to the Yangtze Delta ecosystem.
