Overview
Chongqing wastewater treatment plant serves Rongchang District, Chongqing, China, with a population equivalent of 160,000. It operates under China's national wastewater discharge standards.
The Chongqing wastewater treatment plant is located in Rongchang District, Chongqing, China. It serves a population equivalent of 160,000, classifying it as a medium-to-large agglomeration under Chinese wastewater management frameworks. As a plant of this scale in China, it is expected to comply with the Discharge Standard of Pollutants for Municipal Wastewater Treatment Plant (GB 18918-2002), which mandates secondary treatment with nutrient removal for sensitive areas. Typical Chinese plants of this size employ activated sludge processes with biological nutrient removal. The plant discharges treated effluent into local water bodies within the Yangtze River basin, which ultimately flows into the East China Sea. The receiving waters support diverse aquatic life and are important for regional water quality management, particularly given the high population density and industrial activity in Chongqing.
Environmental context
The plant's treated effluent enters local waterways within the Yangtze River basin, the largest river system in China. The Yangtze flows eastward through densely populated regions before discharging into the East China Sea near Shanghai. This watershed supports critical aquatic ecosystems, including migratory fish species, and is subject to stringent pollution control under China's Water Pollution Prevention and Control Action Plan.
