Jiangsu Wastewater Treatment Plant, Siyang County, Jiangsu, China

The Jiangsu wastewater treatment plant is located in Siyang County, Suqian City, Jiangsu Province, China, serving a population of approximately 58,000 people. The facility is situated in the eastern part of the country, an area characterized by a dense network of rivers and lakes, and is part of the broader municipal infrastructure for the region. The plant operates under China's national wastewater discharge standards, which require secondary treatment for urban wastewater. For a facility serving a medium-sized agglomeration of 58,000 people, compliance with these standards ensures adequate pollutant removal before discharge. The treated effluent is likely discharged into local water bodies that eventually drain into the Hongze Lake, a major freshwater lake in Jiangsu, and subsequently into the Yangtze River via the Huai River system. This connection highlights the plant's role in protecting downstream aquatic ecosystems and water quality in the Yangtze River Delta.

The plant discharges into the local watershed that feeds into Hongze Lake, one of China's largest freshwater lakes, which then drains into the Huai River and ultimately the Yangtze River. The area supports diverse aquatic life and is important for regional water supply and fisheries. Protecting water quality in this system is critical for ecological balance and human use.
