Overview
Chongqing wastewater treatment plant serves Beibei District, Chongqing, China, with a population equivalent of 150,000. It operates under China's national wastewater standards, discharging treated effluent into the Jialing River system.
The Chongqing wastewater treatment plant is located in Beibei District, Chongqing, China, serving a population equivalent of 150,000. The facility is part of the municipal infrastructure for the sprawling Chongqing municipality, a major urban and industrial center in southwestern China. The plant's designed capacity is 1. Under China's national wastewater discharge standards (GB 18918-2002), plants serving agglomerations of this scale are typically required to achieve at least secondary treatment, with more stringent nutrient removal in sensitive watersheds. The plant's operational status and permit details are not publicly available, but it is expected to comply with local environmental protection bureau regulations. The plant discharges treated wastewater into the Jialing River, a major tributary of the Yangtze River. The Jialing River flows through Chongqing and joins the Yangtze at the city center, contributing to the Yangtze's massive flow downstream through the Three Gorges region and ultimately to the East China Sea. The receiving waters support diverse aquatic life and are critical for regional water supply and agriculture.
Environmental context
The plant's effluent enters the Jialing River, which flows into the Yangtze River approximately 50 kilometers downstream. The Yangtze River basin is one of the world's most biodiverse freshwater ecosystems, supporting numerous fish species and migratory birds. The Three Gorges Dam downstream alters flow regimes and sediment transport, making nutrient and pollutant management critical for maintaining water quality in the reservoir and downstream reaches.
