Guangxi Wastewater Treatment Plant, Longxu Town, Wuzhou, Guangxi

The Guangxi wastewater treatment plant is located in Longxu Town (龙圩镇), Wuzhou City, Guangxi Zhuang Autonomous Region, China. It serves a population of approximately 120,000, classifying it as a medium-to-large agglomeration under Chinese wastewater management frameworks. The plant's address along Canghai Avenue places it within the urban infrastructure of the region. As a facility serving over 100,000 people, the plant is expected to meet secondary or advanced treatment standards under China's Discharge Standard of Pollutants for Municipal Wastewater Treatment Plants (GB 18918-2002). Chinese regulations require such plants to achieve at least Class 1-B effluent limits, with sensitive watersheds often mandating Class 1-A (tertiary equivalent). Its scale implies robust infrastructure. The plant discharges into local waterways that ultimately drain into the Xi River system, a major tributary of the Pearl River (Zhu Jiang). The Pearl River basin supports dense populations, agriculture, and industry, and flows into the South China Sea near Guangzhou. Protecting downstream water quality is critical for ecological health and water supply in this heavily utilized basin.

The plant's treated effluent enters the Xi River system, which flows into the Pearl River Delta and then the South China Sea. The Pearl River basin is one of China's most economically vital and ecologically sensitive regions, supporting diverse aquatic life and providing water for millions. Downstream ecosystems include estuarine habitats and coastal wetlands that rely on balanced freshwater inflows and nutrient levels.
