Guangdong Wastewater Treatment Plant, Luohu District, Shenzhen

The Guangdong wastewater treatment plant is located in Luohu District, Shenzhen, within Guangdong Province, China. It serves a population of 650,000, classifying it as a large-scale municipal facility. The plant is situated in a densely urbanized coastal region, reflecting the rapid development of the Pearl River Delta. The plant operates under China's national wastewater discharge standards, which mandate secondary treatment for urban facilities of this scale. The designed capacity is 1.00 (likely in million cubic meters per day), indicating a substantial infrastructure investment. Regulatory oversight is provided by local environmental protection bureaus, ensuring compliance with effluent quality requirements. The plant discharges treated wastewater into the Shenzhen River system, which flows into Deep Bay and ultimately the South China Sea. This coastal discharge point is within 50 km of the coast, making nutrient removal and pathogen control critical to protect marine ecosystems. The surrounding watershed supports diverse aquatic life and is an important migratory corridor for birds.

The plant's treated effluent enters the Shenzhen River, which drains into Deep Bay (Shenzhen Bay) and then the South China Sea. This coastal watershed is ecologically sensitive, supporting mangrove forests and seagrass beds that provide nursery habitats for fish and crustaceans. The bay also serves as a stopover for migratory shorebirds along the East Asian-Australasian Flyway, making water quality management essential for biodiversity conservation.
