Overview
Jiangsu wastewater treatment plant serves Xinwu District, Wuxi, Jiangsu, China, with a designed capacity of 1.00 million cubic meters per day, supporting a population of 800,000.
The Jiangsu wastewater treatment plant is located in Xinwu District, Wuxi, within Jiangsu Province, China. It serves a population of approximately 800,000 people, making it a large-scale municipal facility. The plant is situated along the Grand Canal (Yunhe West Road) in the Xin'an subdistrict, an area characterized by dense urban and industrial development. The plant operates under China's national wastewater discharge standards, which require secondary treatment as a minimum for large urban agglomerations. With a designed capacity of 1.00 million cubic meters per day, the facility is sized to handle significant flows from the surrounding metropolitan area. Chinese regulations for plants of this scale typically mandate advanced treatment to meet Class 1A or 1B discharge standards, especially in sensitive water bodies. The treated effluent is discharged into the local water network, which ultimately drains into Lake Tai (Taihu), one of China's largest freshwater lakes. Lake Tai is ecologically sensitive and has experienced eutrophication issues due to nutrient loading. The plant plays a critical role in protecting the lake's water quality and supporting the region's water resource management.
Environmental context
The plant discharges into the Grand Canal system, which connects to the Yangtze River Delta watershed and ultimately flows into Lake Tai (Taihu). Lake Tai is a large, shallow freshwater lake that supports fisheries, agriculture, and drinking water supplies for millions of people. The lake has historically suffered from algal blooms driven by nitrogen and phosphorus pollution, making nutrient removal a key concern for upstream treatment plants. The facility's location in a densely populated and industrialized region underscores its importance in mitigating downstream ecological impacts.
Frequently asked questions
The plant is located at Yunhe West Road, Xin'an Subdistrict, Xinwu District, Wuxi, Jiangsu Province, China.
The plant serves approximately 800,000 people in the Xinwu District and surrounding areas of Wuxi.
Treated effluent is discharged into the Grand Canal system, which flows into the Yangtze River Delta and eventually reaches Lake Tai.
The plant operates under China's national wastewater discharge standards (GB 18918-2002), which require secondary treatment and often tertiary treatment for large plants to meet Class 1A or 1B limits.
For large agglomerations in China, typical treatment includes primary sedimentation, activated sludge secondary treatment, and often advanced processes like biological nutrient removal or membrane filtration to meet strict discharge standards.
