Jiangsu Wastewater Treatment Plant, Zhouzhuang Town, Jiangyin

The Jiangsu wastewater treatment plant is located in Zhouzhuang Town, Jiangyin City, within the Wuxi metropolitan area of Jiangsu Province, China. It serves a local population of approximately 10,000 people, reflecting its role as a small-scale municipal facility in the densely populated Yangtze River Delta region. As a plant in China, it operates under national wastewater discharge standards (GB 18918-2002) and local environmental regulations. For a facility serving around 10,000 people, secondary treatment is typically required to meet effluent quality standards before discharge. The plant's designed capacity of 1.00 (likely in 10,000 m³/d) suggests it is sized appropriately for its service area. The treated effluent is discharged into local waterways that ultimately drain into the Yangtze River, one of the world's major rivers, which flows into the East China Sea. The plant plays a key role in protecting downstream water quality in the Yangtze River basin, which supports dense populations, agriculture, and industry.

The plant discharges into the Yangtze River basin, which flows through eastern China and empties into the East China Sea. The Yangtze River Delta is a densely populated and industrialized region, making wastewater treatment critical for controlling nutrient pollution and protecting aquatic ecosystems. The downstream environment includes important fisheries and migratory bird habitats, though no specific protected areas are named.
