The Guangxi wastewater treatment plant is located in Hezhou City, Guangxi Zhuang Autonomous Region, China. It serves a population of approximately 175,000, placing it in the medium-to-large agglomeration category. The facility is situated in the urban area of Hezhou, a city in the eastern part of Guangxi near the Gui River basin. As a municipal plant serving over 100,000 people, it operates under China's national wastewater discharge standards, which require secondary treatment as a minimum for urban plants. Chinese regulations mandate that plants of this scale meet Class 1A or 1B effluent standards under the Discharge Standard of Pollutants for Municipal Wastewater Treatment Plant (GB 18918-2002). The plant's treated effluent likely discharges into the Hejiang River or its tributaries, which flow into the Xi River system and ultimately the Pearl River Delta and South China Sea. This water body supports local agriculture, fisheries, and aquatic ecosystems, making effective treatment critical for downstream water quality and ecological health.

The plant discharges into the Hejiang River, a tributary of the Xi River system within the Pearl River basin. The Xi River flows through Guangxi and Guangdong before reaching the Pearl River Delta and the South China Sea. The downstream environment supports diverse aquatic life and is important for regional fisheries and agriculture. Effective wastewater treatment helps protect water quality in this ecologically sensitive river network.
