Overview
Shanghai wastewater treatment plant serves 540,000 people in Hongkou District, Shanghai, China. The facility operates under China's national wastewater standards for large urban agglomerations.
The Shanghai wastewater treatment plant is located in Hongkou District, one of the central urban districts of Shanghai, China. Serving a population of 540,000, it is a large-scale municipal facility critical to the city's wastewater management infrastructure. The plant is situated in a densely populated area with mixed residential and commercial land use. As a major treatment facility in China, the plant is expected to comply with the national Discharge Standard of Pollutants for Municipal Wastewater Treatment Plants (GB 18918-2002). For agglomerations of this size, Chinese regulations typically require secondary or advanced treatment to protect receiving water bodies. The designed capacity is 1.00 (likely in million cubic meters per day or similar unit), indicating substantial treatment capability. The plant's treated effluent ultimately drains into the Huangpu River, which flows through Shanghai and discharges into the Yangtze River estuary and the East China Sea. This water body is ecologically significant, supporting diverse aquatic life and serving as a critical migratory corridor for fish species. The plant plays a key role in reducing nutrient and pollutant loads to this sensitive estuarine environment.
Environmental context
The plant discharges into the Huangpu River, a major tributary of the Yangtze River, which flows into the East China Sea. This estuarine zone supports diverse aquatic ecosystems and is an important migratory corridor for fish and other species. The area is subject to tidal influences and faces pressures from urbanization and industrial activity, making effective wastewater treatment essential for maintaining water quality and ecological health.
