Overview
Jiangsu wastewater treatment plant serves Binhu District, Wuxi, Jiangsu, China, with a designed capacity of 1.00 and a population of 21,000. It lies within 50 km of the coast, discharging into the local watershed.
The Jiangsu wastewater treatment plant is located in Mashan Subdistrict, Binhu District, Wuxi, Jiangsu Province, China. It serves a population of approximately 21,000 and has a designed capacity of 1.00, indicating a small-scale facility typical of peri-urban or rural agglomerations in the region. Chinese wastewater treatment plants of this scale generally operate under national standards such as the Discharge Standard of Pollutants for Municipal Wastewater Treatment Plant (GB 18918-2002). These standards mandate secondary treatment with nutrient removal for sensitive water bodies, and plants serving over 10,000 people are typically required to meet Class 1-A or 1-B effluent limits. The plant's discharge ultimately enters the local water system, which drains into Lake Taihu (Taihu Lake), a large freshwater lake in the Yangtze River Delta. Lake Taihu is ecologically significant as a drinking water source and supports diverse aquatic life, though it has faced eutrophication challenges. The plant's location within 50 km of the coast means its treated effluent may eventually reach the East China Sea via the Yangtze River estuary.
Environmental context
The plant discharges into the local watershed that drains into Lake Taihu, a major freshwater lake in the Yangtze River Delta. Lake Taihu is a critical water resource for drinking, agriculture, and industry, and supports a rich ecosystem of fish and aquatic plants. The lake ultimately connects to the Yangtze River, which flows into the East China Sea. The region's dense population and industrial activity make effective wastewater treatment essential to prevent eutrophication and protect downstream water quality.
