Jiangsu Wastewater Treatment Plant, Lishui District, Nanjing

The Jiangsu wastewater treatment plant is located in Lishui District, Nanjing, Jiangsu Province, China. It serves a population of approximately 83,000 people, classifying it as a medium-sized municipal facility within the region's wastewater infrastructure. As a plant in China, it operates under the national Discharge Standard of Pollutants for Municipal Wastewater Treatment Plants (GB 18918-2002), which sets effluent limits for various pollutants. For a facility serving this population, secondary treatment with nutrient removal is typically required to meet Class 1-A or 1-B standards, depending on the receiving water body's sensitivity. The plant's treated effluent likely discharges into local waterways that drain into the Yangtze River basin, eventually reaching the East China Sea. This downstream connection underscores the plant's role in protecting water quality in a densely populated and economically vital region.

The plant is located inland in Jiangsu Province, within the Yangtze River basin. Treated wastewater likely flows into tributaries of the Yangtze, which empties into the East China Sea. The region supports diverse aquatic life and is important for fisheries and agriculture, making effective treatment critical to prevent eutrophication and protect downstream ecosystems.
