Overview
Sichuan wastewater treatment plant serves Chengdu, Sichuan, China, with a population equivalent of 86,300. It discharges into the local river system within the Yangtze basin.
The Sichuan wastewater treatment plant is located in the Wuhou District of Chengdu, Sichuan Province, China, along Jiang'an Binhe North Road. It serves a population equivalent of approximately 86,300, placing it in the medium agglomeration category under Chinese wastewater regulations. As a plant in China, it operates under national standards such as the Discharge Standard of Pollutants for Municipal Wastewater Treatment Plant (GB 18918-2002). For a facility of this scale, secondary treatment with nutrient removal is typically required to meet Class 1-A or 1-B effluent standards, depending on the receiving water body's sensitivity. The plant's treated effluent is discharged into the Jin River, a tributary of the Min River, which flows into the Yangtze River. This contributes to the protection of the Yangtze basin's water quality, supporting aquatic life and downstream ecosystems in one of China's most important river systems.
Environmental context
The plant discharges into the Jin River, a tributary of the Min River, which ultimately joins the Yangtze River. The Yangtze basin supports diverse aquatic ecosystems and is a critical water resource for millions of people. The plant's location in a densely populated urban area underscores its role in preventing untreated sewage from entering local waterways, thereby reducing eutrophication risks and protecting downstream habitats.
