Guangdong Wastewater Treatment Plant, Dongguan, China

The Guangdong wastewater treatment plant is located in Qingxi Town, Dongguan, Guangdong Province, China. It serves a population of 180,000, classifying it as a large agglomeration under Chinese wastewater management frameworks. The plant's designed capacity is 1. As a facility in China, the plant is subject to the national Discharge Standard of Pollutants for Municipal Wastewater Treatment Plants (GB 18918-2002), which sets effluent limits based on receiving water sensitivity. For large agglomerations like this, advanced treatment is often required to meet stringent standards, especially in densely populated and industrialized regions like the Pearl River Delta. The plant discharges into local waterways that ultimately drain into the Pearl River Delta and the South China Sea. This region is ecologically significant, supporting diverse aquatic life and serving as a critical migratory corridor for fish and birds. The plant's performance is vital for protecting downstream water quality and the broader marine environment.

The plant's treated effluent flows into the local river network, which is part of the Pearl River Basin, one of China's largest and most economically important watersheds. The basin drains into the Pearl River Delta and then the South China Sea. This area supports diverse aquatic ecosystems, including important fisheries and migratory species. Effective wastewater treatment is crucial to prevent eutrophication and protect downstream habitats.
