Chongqing Wastewater Treatment Plant, Wanzhou District, Chongqing, China

The Chongqing wastewater treatment plant is located in Baianba Subdistrict, Wanzhou District, Chongqing, China. It serves a population of approximately 82,000 people, classifying it as a medium-sized agglomeration under Chinese wastewater management standards. The plant's designed capacity is 1.00 unit, reflecting its role in treating municipal wastewater from this urban area. As a facility in China, the plant operates under national wastewater discharge standards, which require secondary treatment for urban wastewater. It is expected to comply with China's Water Pollution Prevention and Control Law, which mandates appropriate treatment levels for protecting water quality. The plant discharges treated effluent into local water bodies that ultimately flow into the Yangtze River basin. The Yangtze River is a critical ecological and economic resource, supporting diverse aquatic life and providing water for millions. The plant's operations contribute to reducing pollution loads in this major river system, helping to protect downstream ecosystems and water quality.

The plant's treated effluent enters local waterways that drain into the Yangtze River, one of Asia's longest rivers, which flows into the East China Sea. The Yangtze basin supports a rich biodiversity, including numerous fish species and migratory birds. Protecting water quality in this watershed is essential for maintaining ecological balance and supporting human uses such as drinking water and agriculture.
