Overview
Chongqing wastewater treatment plant serves 110,000 people in Shapingba District, Chongqing, China. It operates under national standards for municipal wastewater treatment.
The Chongqing wastewater treatment plant is located in Shapingba District, Chongqing, China, serving a population of approximately 110,000. The plant is part of the municipal infrastructure for one of China's largest metropolitan areas, situated along the Jialing River near its confluence with the Yangtze River. The plant operates under China's national wastewater discharge standards, which mandate secondary treatment for urban wastewater. For a facility serving over 100,000 people, compliance with Class 1A or 1B discharge standards is typical, requiring biological treatment and nutrient removal to protect receiving waters. The plant discharges treated effluent into the Jialing River, a major tributary of the Yangtze River. The Yangtze River basin supports diverse aquatic ecosystems and provides drinking water for millions downstream. Effective treatment at this plant helps reduce nutrient and pollutant loads, contributing to the ecological health of the Jialing-Yangtze river system.
Environmental context
The plant discharges into the Jialing River, which flows into the Yangtze River, one of the world's most ecologically significant waterways. The Yangtze basin supports a wide range of aquatic species, including endangered fish like the Chinese sturgeon. Nutrient and pollutant control from upstream treatment plants is critical to prevent eutrophication and maintain water quality in this densely populated region.
