Overview
Chongqing wastewater treatment plant serves 200,000 people in Liangjiang New District, Chongqing, China. The facility operates under national wastewater regulations for large agglomerations.
The Chongqing wastewater treatment plant is located in Liangjiang New District, a major urban development area in Chongqing, China. Serving a population of 200,000, it is classified as a large agglomeration under Chinese wastewater management standards. The plant plays a critical role in managing municipal wastewater for this rapidly growing region. As a large-scale facility, the plant is expected to meet secondary or advanced treatment standards in line with China's national discharge limits (GB 18918-2002). Chinese regulations mandate effective nutrient removal for plants serving over 100,000 people, especially those discharging into sensitive water bodies. The designed capacity is 1.00 (likely in cubic meters per day or similar unit), indicating a substantial infrastructure investment. The treated effluent from the plant ultimately flows into the Yangtze River basin, which is the largest river system in China and a critical water resource for the region. The Yangtze River supports diverse aquatic ecosystems and provides drinking water for millions downstream. Proper treatment at this plant helps reduce pollution loads entering the river, protecting both ecological health and human water uses.
Environmental context
The plant discharges into the Yangtze River basin, which flows eastward through central China before emptying into the East China Sea near Shanghai. The Yangtze is one of the world's most biodiverse rivers, supporting numerous fish species and migratory birds. Downstream ecosystems include important wetlands and floodplains that rely on good water quality. Effective wastewater treatment at this plant helps mitigate eutrophication and toxic contamination risks in the river system.
Frequently asked questions
The plant is located in Liangjiang New District, Chongqing, China, at coordinates 29.567 N, 106.529 E.
The plant serves approximately 200,000 people, classifying it as a large agglomeration under Chinese wastewater regulations.
The treated effluent flows into the Yangtze River basin, which is the longest river in Asia and a vital water resource for central and eastern China.
The plant must comply with China's Discharge Standard of Pollutants for Municipal Wastewater Treatment Plant (GB 18918-2002), which sets limits for COD, BOD, nitrogen, phosphorus, and other pollutants. Large agglomerations like this typically require secondary or advanced treatment.
China's wastewater treatment is governed by national standards and local environmental protection bureaus. Plants serving over 100,000 people are subject to stricter discharge limits, especially in sensitive watersheds like the Yangtze River basin. The plant likely holds a pollutant discharge permit from the Chongqing Municipal Ecology and Environment Bureau.
