KA Hohenbostel Wastewater Treatment Plant, Bienenbüttel, Niedersachsen

KA Hohenbostel is a municipal wastewater treatment plant located in Bienenbüttel, a municipality in the district of Uelzen, Niedersachsen, Germany. The plant serves a population of approximately 6,016 people, classifying it as a small to medium agglomeration under the EU Urban Waste Water Treatment Directive (91/271/EEC). As a German plant of this scale, it is expected to provide at least secondary treatment to meet the requirements of the EU UWWTD. The plant operates under Germany's national implementation of the directive, which mandates secondary biological treatment for agglomerations above 2,000 population equivalent. The plant's discharge is regulated by the local water authority, ensuring compliance with effluent standards. The treated wastewater is discharged into the local water system, which ultimately drains into the Elbe River basin. The Elbe flows through northern Germany into the North Sea, supporting diverse aquatic ecosystems. The plant plays a key role in protecting the water quality of the region's streams and rivers, which are important for both ecological health and downstream uses.

The plant discharges into the Elbe River basin, which flows through Niedersachsen and into the North Sea. This watershed supports a variety of aquatic life, including fish species such as the European eel and Atlantic salmon. The Elbe estuary is an ecologically sensitive area that provides critical habitat for migratory birds and fish. Proper wastewater treatment at KA Hohenbostel helps reduce nutrient and pollutant loads, protecting downstream water quality and the ecological integrity of the Elbe and the North Sea.
