Overview
Jiangsu wastewater treatment plant serves Donghai County, Jiangsu, China, with a population of 160,000. It is located inland, over 50 km from the coast, and discharges into local waterways.
The Jiangsu wastewater treatment plant is located in Donghai County, within Lianyungang City, Jiangsu Province, China. It serves a population of approximately 160,000 people, classifying it as a medium-to-large agglomeration under Chinese wastewater management standards. The plant is situated inland, more than 50 km from the coast, and its operations are part of the municipal infrastructure for the region. Under China's national wastewater discharge standards, plants serving populations of this scale are typically required to achieve at least secondary treatment, with some facilities adopting advanced treatment to meet stricter local water quality goals. It operates within the regulatory framework of China's Water Pollution Prevention and Control Law, which mandates compliance with discharge limits for receiving water bodies. The plant's treated effluent is discharged into local rivers that ultimately flow into the Yellow Sea via the Huai River system or other regional waterways. The downstream environment supports diverse aquatic life and is important for regional agriculture and fisheries. Protecting water quality in this watershed is critical for both ecological health and human use, including drinking water and irrigation.
Environmental context
The plant discharges into local rivers that drain into the Huai River basin, eventually reaching the Yellow Sea.
