Overview
Jiangsu wastewater treatment plant serves Pei County (沛县) in Jiangsu Province, China, with a population of 183,000. It discharges treated effluent into local waterways within the Huai River basin.
The Jiangsu wastewater treatment plant is located in Pei County (沛县), Xuzhou City, Jiangsu Province, China. It serves a population of approximately 183,000, classifying it as a large agglomeration under Chinese wastewater regulations. The plant is situated in an inland area, more than 50 km from the coast, and its operations are part of the municipal infrastructure managed by local authorities. As a large-scale facility, the plant is expected to meet secondary or advanced treatment standards under China's national wastewater discharge regulations (GB 18918-2002). These standards align with the country's efforts to reduce pollution in major river basins. The plant's scale suggests it plays a key role in managing urban wastewater in the region. The treated effluent likely enters local streams that flow into the Huai River system, which ultimately drains into the Yellow Sea. The Huai River basin is ecologically significant, supporting diverse aquatic life and providing water for agriculture and industry. Effective treatment at this plant helps protect downstream water quality and ecosystem health.
Environmental context
The plant discharges into the Huai River basin, a major water system in eastern China that flows into the Yellow Sea. This basin supports a variety of freshwater species and is an important resource for irrigation and fisheries. Downstream ecosystems rely on adequate treatment to prevent nutrient loading and maintain biodiversity.
