Overview
Hainan wastewater treatment plant serves the Jiyang district of Sanya, China, with a designed capacity of 1.00 unit and a population equivalent of 41,400. It is located within 50 km of the coast, discharging into the South China Sea.
The Hainan wastewater treatment plant is located in the Jiyang district of Sanya, on the southern coast of Hainan Island, China. It serves a population equivalent of approximately 41,400 people, making it a medium-sized facility for the region. As a municipal wastewater facility in China, the plant operates under national environmental regulations, including the Water Pollution Prevention and Control Law. For agglomerations of this scale, secondary treatment is typically required, with potential for advanced treatment if discharging into sensitive water bodies. The plant's coastal proximity suggests it may be subject to additional discharge standards to protect marine environments. The treated effluent from the plant ultimately reaches the South China Sea, a major marine ecosystem that supports diverse aquatic life and important fisheries. The plant plays a key role in protecting coastal water quality in the Sanya area, a popular tourist destination. Its operation helps mitigate nutrient and pollutant loads that could otherwise impact coral reefs and seagrass beds in the region.
Environmental context
The Hainan plant discharges into the South China Sea, a semi-enclosed sea that supports high biodiversity, including coral reefs, mangroves, and migratory species. The coastal waters near Sanya are ecologically sensitive due to tourism and fishing pressures. Effective wastewater treatment is critical to prevent eutrophication and protect marine habitats in this tropical ecosystem.
