Jiangsu Wastewater Treatment Plant, Jurong, Jiangsu Province, China

The Jiangsu wastewater treatment plant is located in Jurong City, Jiangsu Province, China, serving an estimated population of 320,000. As a municipal facility, it plays a key role in managing wastewater from the urban area of Jurong, a city in the Yangtze River Delta region. Under China's national wastewater discharge standards (GB 18918-2002), plants serving agglomerations of this scale are typically required to achieve at least secondary treatment, with nutrient removal in sensitive areas. The plant's design and operation align with these regulatory requirements to protect receiving waters. The treated effluent is discharged into local waterways that ultimately drain into the Yangtze River basin, one of China's most ecologically and economically significant river systems. The Yangtze supports diverse aquatic life and provides water for millions of people downstream.

The plant's discharge enters the local river network within the Yangtze River basin, which flows eastward into the East China Sea. The Yangtze estuary supports critical habitats for migratory fish and other aquatic species. Nutrient loading from urban wastewater can contribute to eutrophication in downstream lakes and coastal zones, making effective treatment essential for ecological balance.
