Jiangsu Wastewater Treatment Plant, Xishan District, Wuxi | China

The Jiangsu wastewater treatment plant is located in Xishan District, Wuxi, within Jiangsu Province, China. It serves a population of approximately 89,000 people, classifying it as a medium-sized agglomeration under Chinese municipal wastewater management. The plant is situated in the Yangtze River Delta region, a densely populated and economically vital area. As a Chinese wastewater facility, the plant is subject to the national Discharge Standard of Pollutants for Municipal Wastewater Treatment Plants (GB 18918-2002), which sets effluent limits based on receiving water sensitivity. For plants serving populations over 50,000, secondary treatment with nutrient removal is typically required. The designed capacity is 1. The plant discharges into local waterways that ultimately drain into the Yangtze River and then the East China Sea. The Yangtze River basin supports diverse aquatic life and provides water for millions of people. Effective treatment at this plant helps protect downstream water quality in a region facing pressures from industrial and urban development.

The plant's treated effluent flows into local rivers and canals within the Yangtze River Delta, eventually reaching the Yangtze River and the East China Sea. This watershed supports important fisheries and provides drinking water for downstream communities. The region's dense population and industrial activity place high demands on water quality management, making the plant's performance critical for maintaining ecological balance in the delta.
