Overview
Hubei wastewater treatment plant serves Gongan County, Hubei, China, with a population of 163,000. The facility operates under China's national wastewater discharge standards.
The Hubei wastewater treatment plant is located in Gongan County, Hubei Province, China, serving a population of approximately 163,000. As part of China's expanding urban wastewater infrastructure, the plant plays a key role in managing municipal sewage in this region of the Yangtze River basin. Under China's Discharge Standard of Pollutants for Municipal Wastewater Treatment Plants (GB 18918-2002), plants serving agglomerations of this scale are expected to meet at least Class 1-B standards, with many larger facilities required to achieve Class 1-A for sensitive receiving waters. Typical facilities in Hubei employ biological treatment processes such as A2/O or oxidation ditch. The treated effluent likely discharges into a tributary of the Yangtze River, which ultimately flows into the East China Sea. The Yangtze basin supports diverse aquatic ecosystems and is a critical water resource for millions of people. Proper treatment at this plant helps reduce nutrient and pollutant loads entering the river system.
Environmental context
The plant is situated in the Yangtze River basin, one of the world's most ecologically significant freshwater systems. The Yangtze flows eastward through Hubei and eventually discharges into the East China Sea near Shanghai. Downstream waters support a wide range of aquatic life, including endemic fish species and migratory birds. Effective wastewater treatment in this region is essential to mitigate eutrophication and protect water quality in the river and its estuary.
