KA Steenfelde Wastewater Treatment Plant, Völlenerfehn, Niedersachsen

KA Steenfelde, officially designated as plant 4570222001, is a municipal wastewater treatment facility located in Völlenerfehn, part of Westoverledingen in the Landkreis Leer district of Niedersachsen, Germany. The plant serves a population of approximately 17,483 people, classifying it as a medium-sized agglomeration under European Union classification. As a German wastewater treatment plant, KA Steenfelde operates under the EU Urban Waste Water Treatment Directive 91/271/EEC, which requires secondary treatment for agglomerations of this size. German plants typically adhere to strict national standards that implement the directive, with permits issued by the relevant state authority (Landesamt). The treated effluent from KA Steenfelde is discharged into local watercourses that ultimately drain into the North Sea via the Ems River system. The plant plays a key role in protecting the region's water quality, supporting aquatic ecosystems in the low-lying, agriculturally intensive landscape of East Frisia.

KA Steenfelde discharges into the local drainage network that feeds the Ems River, which flows northward into the Dollart estuary and then the North Sea. The Ems basin supports diverse aquatic life, including migratory fish species, and the estuary is an important area for waterfowl. The plant's operation helps maintain water quality in this ecologically sensitive region, which is influenced by both agricultural runoff and tidal dynamics.
