Overview
Hainan wastewater treatment plant serves Tunchang County in Hainan Province, China, with a population equivalent of 30,000. The facility discharges into local water bodies within the Nandu River basin.
The Hainan wastewater treatment plant is located in Tunchang County, Hainan Province, China. It serves a population of approximately 30,000, placing it in the medium agglomeration category. The plant is situated inland, more than 50 km from the coast, and its operations are part of the regional wastewater infrastructure managed under Chinese environmental regulations. Under China's Water Pollution Prevention and Control Law, wastewater treatment plants serving populations of this scale are typically required to meet Class 1A or 1B discharge standards, which mandate secondary treatment with nutrient removal. The regulatory framework ensures that facilities of this size operate under permits issued by the local environmental protection bureau. The treated effluent from the plant is discharged into local streams that flow into the Nandu River, the largest river in Hainan. The Nandu River drains into the South China Sea, supporting diverse aquatic life and providing water for agriculture and communities downstream. The plant plays a key role in protecting water quality in this ecologically sensitive tropical watershed.
Environmental context
The plant discharges into tributaries of the Nandu River, which flows through central Hainan and empties into the South China Sea near Haikou. The Nandu River basin supports important freshwater ecosystems and is a vital water source for the region. Downstream coastal areas include mangrove habitats and seagrass beds that are sensitive to nutrient pollution, making effective wastewater treatment critical for maintaining ecological balance.
