Overview
Guangdong wastewater treatment plant serves 380,000 people in Zhaoqing, Guangdong, China. It discharges into the Xi River basin, a major tributary of the Pearl River Delta.
The Guangdong wastewater treatment plant is located in Zhaoqing, a city in Guangdong Province, China, along the Xi River (Xijiang). It serves a population of approximately 380,000, classifying it as a large agglomeration under Chinese wastewater regulations. The plant is situated in the urban Duanzhou District, near the Xi River ecological corridor. As a large-scale municipal facility, the plant is expected to meet China's Discharge Standard of Pollutants for Municipal Wastewater Treatment Plant (GB 18918-2002), which mandates secondary treatment with nutrient removal for plants of this size. The regulatory framework in China requires advanced treatment for plants discharging into sensitive water bodies, such as the Xi River, which flows into the Pearl River Delta. The treated effluent is discharged into the Xi River, a major tributary of the Pearl River, which ultimately drains into the South China Sea. The Xi River supports diverse aquatic life and is an important water source for the region. The plant plays a key role in protecting downstream water quality in the densely populated Pearl River Delta.
Environmental context
The plant discharges into the Xi River, which flows through Zhaoqing and joins the Pearl River Delta before reaching the South China Sea. The Xi River basin supports important fisheries and provides drinking water for millions. The Pearl River Delta is an ecologically sensitive estuary with mangrove habitats and migratory bird routes, making nutrient and pollutant control critical.
