Overview
KA Hagen is a municipal wastewater treatment plant serving approximately 14,500 people in Hagen am Teutoburger Wald, Niedersachsen, Germany. It operates under the EU Urban Waste Water Treatment Directive.
KA Hagen is a municipal wastewater treatment plant located in Hagen am Teutoburger Wald, a town in the district of Osnabrück, Niedersachsen, Germany. The plant serves a population of around 14,500, classifying it as a medium-sized agglomeration under German and EU regulations. As a German plant, KA Hagen is subject to the EU Urban Waste Water Treatment Directive (91/271/EEC), which requires secondary treatment for agglomerations of this size. The plant's treatment processes are designed to meet national standards set by the Wasserhaushaltsgesetz (WHG) and Abwasserverordnung (AbwV), ensuring effluent quality protects receiving waters. The plant discharges treated wastewater into local watercourses that ultimately drain into the Ems River basin, which flows into the North Sea. This region is characterized by agricultural and rural landscapes, and the plant plays a key role in maintaining water quality in the local watershed.
Environmental context
The plant's treated effluent enters small streams in the Hase River system, a tributary of the Ems River. The Ems flows northward through Niedersachsen and discharges into the Dollart estuary and the North Sea. This watershed supports diverse aquatic life and is an important ecological corridor. The plant's operations help protect downstream water quality in a region with mixed agricultural and natural land use.
