Guangdong, Gaoming | China Wastewater

Overview

Guangdong wastewater treatment plant serves Gaoming District, Foshan, Guangdong, China, with a population equivalent of 490,000. It operates under China's national wastewater discharge standards.

The Guangdong wastewater treatment plant is located in Gaoming District, Foshan, Guangdong Province, China. It serves a population equivalent of 490,000, classifying it as a large-scale municipal facility within the Pearl River Delta region. As a major treatment plant in China, it is subject to the national Discharge Standard of Pollutants for Municipal Wastewater Treatment Plants (GB 18918-2002), which sets effluent limits for conventional pollutants, nutrients, and pathogens. For plants of this scale, secondary treatment with nutrient removal is typically required, especially in sensitive water bodies. The plant's treated effluent is discharged into local waterways that ultimately drain into the Pearl River system, which flows into the South China Sea. The Pearl River Delta is a densely populated and economically vital region, where proper wastewater treatment is critical for protecting downstream aquatic ecosystems and ensuring water quality for industrial and domestic use.

Environmental context

The plant discharges into the Pearl River basin, which flows through Guangdong and into the South China Sea. The downstream environment includes estuarine and coastal habitats that support diverse aquatic life, including fisheries and migratory species. Nutrient and pollutant loads from the region's dense urban and industrial areas pose risks to water quality, making advanced treatment essential for ecological health.
