Chongqing Wastewater Treatment Plant, Liangjiang New Area | China

The Chongqing wastewater treatment plant is located in Liangjiang New Area, a major urban district of Chongqing, China. With a population served of 200,000, it is classified as a large agglomeration under Chinese wastewater management standards. The plant plays a critical role in treating municipal wastewater from this rapidly developing region. The plant's designed capacity is 1.00 (likely in cubic meters per day or similar unit). Under China's Water Pollution Prevention and Control Law, large-scale plants like this are expected to achieve at least secondary treatment, with many upgraded to tertiary standards to protect sensitive water bodies. The plant's operational status and permit details are not disclosed, but it is part of the municipal infrastructure managed by local authorities. The treated effluent is discharged into the Yangtze River basin, as Chongqing lies along the upper reaches of the Yangtze. The river flows eastward through central China, eventually reaching the East China Sea near Shanghai. The plant's operations help reduce nutrient and pollutant loads entering the Yangtze, supporting downstream water quality and aquatic ecosystems, including important fisheries and biodiversity corridors.

The plant discharges into the Yangtze River, China's longest waterway, which flows through multiple provinces before emptying into the East China Sea. The upper Yangtze basin supports diverse aquatic life, including endangered species like the Chinese sturgeon. Downstream, the river passes through major industrial and agricultural regions, making nutrient and pollutant control critical. The plant's location in a rapidly urbanizing area underscores its role in protecting the river's ecological health.
