Overview
Chongqing wastewater treatment plant serves Nancheng Street in Nanchuan District, Chongqing, China. The facility handles a population equivalent of 100,000 and operates under China's national wastewater regulations.
The Chongqing wastewater treatment plant is located in Nancheng Street, Nanchuan District, within the municipality of Chongqing, China. It serves a population of approximately 100,000, classifying it as a medium-to-large urban agglomeration under Chinese wastewater management standards. Under China's national wastewater discharge standards (GB 18918-2002), plants of this scale are typically required to achieve at least secondary treatment, with more stringent nutrient removal in sensitive watersheds. Regulatory compliance is expected through local environmental protection bureau oversight. The plant discharges into the local water system, which ultimately drains into the Yangtze River basin via tributaries of the Wu River or similar systems. The Yangtze River is a critical ecological and economic artery, supporting diverse aquatic life and providing water for millions downstream. Proper treatment helps protect water quality in this major river system.
Environmental context
The plant's receiving waters flow into the Yangtze River basin, one of the world's most ecologically significant river systems. The Yangtze supports numerous fish species, including the endangered Chinese sturgeon, and provides drinking water for over 400 million people. Downstream environments include the Three Gorges Reservoir area and the East China Sea, making nutrient and pollutant control vital for both local and regional ecosystem health.
