Jiangxi Wastewater Treatment Plant, Xihu District, Nanchang | China

The Jiangxi wastewater treatment plant is located in Xihu District, Nanchang, the capital of Jiangxi Province in southeastern China. It serves a population of approximately 180,000, classifying it as a medium-to-large agglomeration under Chinese wastewater management frameworks. The plant is situated in the urban area of Nanchang, near the Gan River, a major tributary of Poyang Lake. As a facility serving over 100,000 people, the plant is expected to meet China's Discharge Standard of Pollutants for Municipal Wastewater Treatment Plants (GB 18918-2002), which mandates secondary treatment with nutrient removal for plants of this scale. The designed capacity is 1. Chinese regulations require regular monitoring and reporting to local environmental protection bureaus. The treated effluent is discharged into the Gan River, which flows northward into Poyang Lake, China's largest freshwater lake. Poyang Lake is a critical wetland ecosystem that supports migratory birds and diverse aquatic life, and it ultimately drains into the Yangtze River. The plant's operation is essential for protecting water quality in this ecologically significant watershed.

The plant discharges into the Gan River, a major tributary of Poyang Lake, which is a vital freshwater lake and wetland ecosystem in Jiangxi Province. Poyang Lake supports a rich diversity of fish and bird species, including migratory waterfowl along the East Asian-Australasian Flyway. The lake connects to the Yangtze River, one of the world's most important river systems. Effective wastewater treatment is crucial to prevent nutrient pollution and maintain the ecological health of this downstream environment.
