Guangxi Wastewater Treatment Plant, Sixian, Liuzhou, Guangxi, China

The Guangxi wastewater treatment plant is located in Sixian, Liujiang District, Liuzhou, within the Guangxi Zhuang Autonomous Region of China. It serves a population of approximately 82,000 residents, classifying it as a medium-sized municipal facility in the region's wastewater infrastructure. As a Chinese municipal wastewater plant, it operates under China's national discharge standards (GB 18918-2002) and relevant local environmental regulations. For agglomerations of this scale, secondary treatment with nutrient removal is typically required to meet effluent quality standards for inland water bodies. The plant discharges treated effluent into the local watershed, which ultimately drains into the Pearl River system via the Liu River and Qian River. This river network supports diverse aquatic life and provides water for downstream agricultural and urban uses in southern China.

The plant's treated effluent flows into the Liu River, a tributary of the Qian River, which joins the Pearl River system. The Pearl River basin is a major ecological and economic corridor in southern China, supporting diverse freshwater species and providing water for millions of people. Downstream, the river reaches the South China Sea near Guangzhou, making nutrient and pollutant control critical for coastal water quality.
