Coesfeld Wastewater Treatment Plant | Serving Coesfeld, Nordrhein-Westfalen

The Coesfeld wastewater treatment plant is located in the town of Coesfeld, in the district of Kreis Coesfeld, Nordrhein-Westfalen, Germany. Serving a population of around 115,000, it is classified as a large agglomeration under EU regulations. The plant is part of the region's municipal wastewater infrastructure, managing effluent from both residential and industrial sources. As a facility serving over 100,000 people, Coesfeld is subject to the EU Urban Waste Water Treatment Directive (91/271/EEC), which requires secondary biological treatment as a minimum. For sensitive areas, tertiary treatment for nutrient removal may be mandated. The regulatory framework ensures compliance with discharge standards. The treated effluent from Coesfeld is discharged into local watercourses that ultimately drain into the Rhine River basin. The Rhine is a major European waterway flowing through Germany into the North Sea. The plant plays a key role in protecting the water quality of the Rhine and its tributaries, supporting aquatic ecosystems and downstream communities.

The Coesfeld plant discharges into the local watershed that feeds into the Rhine River, one of Europe's most important waterways. The Rhine flows through Germany and the Netherlands before reaching the North Sea. The river supports diverse aquatic life and is a vital corridor for migratory fish. The plant's operations help maintain water quality standards in this ecologically sensitive basin, reducing nutrient loads and preventing pollution that could impact downstream habitats.
