Guangxi Wastewater Treatment Plant, Bobai Town, Guangxi, China

The Guangxi wastewater treatment plant is located in Bobai Town, Bobai County, Yulin City, Guangxi Zhuang Autonomous Region, China. It serves a population of approximately 113,500, classifying it as a medium-to-large agglomeration under Chinese wastewater management frameworks. As a plant in China, it is subject to the Discharge Standard of Pollutants for Municipal Wastewater Treatment Plant (GB 18918-2002), which sets effluent limits for conventional pollutants and nutrients. For agglomerations of this scale, secondary treatment with nutrient removal is typically required, especially in sensitive watersheds. The plant's treated effluent likely discharges into a local waterway within the broader Pearl River basin, which ultimately flows into the South China Sea. The surrounding region is ecologically significant, supporting diverse aquatic life and providing water for agriculture and urban use.

The plant is located inland in Guangxi, over 50 km from the coast, and its treated effluent likely enters a tributary of the Pearl River system. This river network drains into the South China Sea, supporting important fisheries and mangrove ecosystems. The watershed is subject to seasonal monsoon rains, which can affect dilution capacity and pollutant transport.
