Overview
Jiangsu wastewater treatment plant serves Chongchuan District, Nantong, Jiangsu, China, with a population equivalent of 1,000,000. The plant has a designed capacity of 1.00 (unit unspecified) and is located within 50 km of the coast.
The Jiangsu wastewater treatment plant is located in Chongchuan District, Nantong, in Jiangsu Province, China. It serves a population equivalent of 1,000,000, classifying it as a large agglomeration under Chinese wastewater regulations. The plant's designed capacity is 1.00 (unit unspecified), and it is situated within 50 km of the coast, indicating potential discharge into coastal waters. As a large-scale facility in China, the plant is subject to the national Discharge Standard of Pollutants for Municipal Wastewater Treatment Plant (GB 18918-2002), which sets effluent limits for various pollutants. For plants serving over 500,000 people, advanced treatment (tertiary) is typically required to meet stricter standards, especially in environmentally sensitive areas. Regulatory expectations for this scale are high. Given its proximity to the coast, treated effluent likely discharges into the Yangtze River estuary or directly into the East China Sea. This region supports diverse aquatic life and is an important migratory corridor for fish and birds. The plant plays a critical role in protecting downstream water quality and the coastal ecosystem from nutrient pollution and pathogens.
Environmental context
The plant is located in the Yangtze River Delta, one of China's most densely populated and industrialized regions. Treated effluent likely enters the Yangtze River system, which flows into the East China Sea. The downstream environment includes critical estuarine and coastal habitats that support fisheries and migratory bird populations. Nutrient loading from wastewater can contribute to eutrophication in coastal waters, making advanced treatment essential for protecting these ecosystems.
Frequently asked questions
The plant is located in Chongchuan District, Nantong, Jiangsu Province, China, near the Yangtze River estuary.
The plant serves a population equivalent of 1,000,000, making it a large-scale municipal facility.
The plant is within 50 km of the coast, so treated effluent likely discharges into the Yangtze River or directly into the East China Sea, subject to national discharge standards.
The plant operates under China's Discharge Standard of Pollutants for Municipal Wastewater Treatment Plant (GB 18918-2002), which sets effluent limits for large agglomerations.
For large agglomerations over 500,000 PE, Chinese regulations typically require advanced (tertiary) treatment to meet stringent effluent standards, especially in coastal or sensitive areas.
