Versmold Wastewater Treatment Plant, Versmold, Nordrhein-Westfalen, Germany

The Versmold wastewater treatment plant is located in the city of Versmold, within the Kreis Gütersloh district of Nordrhein-Westfalen, Germany. Serving a population of approximately 67,666, the plant is a key component of the region's municipal wastewater infrastructure, handling domestic and industrial flows from the urban area. As a German facility, the plant operates under the EU Urban Waste Water Treatment Directive (91/271/EEC), which requires secondary treatment for agglomerations with a population equivalent (PE) between 10,000 and 150,000. For larger agglomerations, more stringent treatment may be required if the receiving water body is designated as sensitive. The plant's treatment processes are designed to meet these regulatory standards, ensuring compliance with national and European water quality objectives. The treated effluent from the plant is discharged into local watercourses that ultimately drain into the Ems River basin, which flows northward through Lower Saxony into the North Sea. The plant plays a vital role in protecting the ecological health of these waterways, reducing nutrient loads and organic pollutants to support aquatic life and downstream water quality.

The Versmold plant discharges into the local tributaries of the Ems River, which flows through the lowlands of northwestern Germany before reaching the North Sea. The Ems basin supports diverse aquatic habitats and is an important corridor for migratory fish species. The plant's nutrient removal helps mitigate eutrophication risks in the river and the downstream coastal zone.
