KA Hemmoor Wastewater Treatment Plant, Hemmoor, Niedersachsen

KA Hemmoor is a municipal wastewater treatment plant located in Hemmoor, Niedersachsen, Germany. The plant serves a population of around 12,164, classifying it as a medium-sized agglomeration under EU regulations. It is situated inland in the district of Landkreis Cuxhaven, near the Oste river. As a German plant serving over 10,000 people, KA Hemmoor is subject to the EU Urban Waste Water Treatment Directive (91/271/EEC), which requires secondary treatment as a minimum. The plant's designed capacity is 1.00 (likely in thousands of cubic meters per day), indicating it is sized to handle the local load. Typical plants of this scale employ biological treatment stages. The treated effluent from KA Hemmoor is discharged into the local watershed, which drains into the Oste river and eventually into the Elbe estuary and the North Sea. The plant plays a key role in protecting the water quality of the Oste and downstream ecosystems, including the Elbe's sensitive estuarine environment.

KA Hemmoor discharges into the Oste river, a tributary of the Elbe, which flows into the North Sea near Cuxhaven. The Oste supports diverse aquatic life and is part of a network of lowland rivers in Niedersachsen. The downstream Elbe estuary is ecologically sensitive, providing habitat for migratory fish and bird species. The plant's treatment helps reduce nutrient and pollutant loads to these waters.
