Guangxi Wastewater Treatment Plant, Zhushan, Guangxi, China

The Guangxi wastewater treatment plant is located in Zhushan, a town within Pingxiang City, Guangxi Zhuang Autonomous Region, China. It serves a population of approximately 62,000 people, classifying it as a medium-sized agglomeration under Chinese wastewater management standards. As a facility in China, the plant is subject to the national Discharge Standard of Pollutants for Municipal Wastewater Treatment Plants (GB 18918-2002), which sets effluent limits based on the receiving water body's sensitivity. For plants of this scale, secondary treatment with nutrient removal is typically required, especially if discharging into sensitive waters. The plant's treated effluent likely discharges into a local watercourse within the Zuo River basin, which flows into the Pearl River system and eventually reaches the South China Sea. This downstream connection underscores the plant's role in protecting both local freshwater resources and the coastal marine environment.

The plant discharges into the Zuo River basin, a tributary of the Pearl River system, which flows through southern China into the South China Sea. The Pearl River Delta is a densely populated and ecologically important region, supporting diverse aquatic life and providing water for agriculture and industry. The plant's operations help mitigate nutrient and pollutant loads that could otherwise contribute to eutrophication and habitat degradation in downstream waters.
