Kremmen Wastewater Treatment Plant, Brandenburg, Germany

The Kremmen wastewater treatment plant is located in the town of Kremmen, in the Oberhavel district of Brandenburg, Germany. The facility serves a population of about 11,202, placing it in the medium agglomeration category under EU regulations. As a German plant, it operates under the EU Urban Waste Water Treatment Directive 91/271/EEC, which requires secondary treatment for agglomerations of this size. The directive also mandates more advanced treatment if the receiving waters are sensitive areas. Compliance with the directive ensures a minimum level of treatment. The plant discharges treated wastewater into local watercourses that eventually flow into the Havel River, a tributary of the Elbe River. The Elbe drains into the North Sea. The surrounding region is characterized by agricultural land and small settlements, and the plant plays a key role in protecting local groundwater and surface water quality.

The treated effluent from the Kremmen plant enters the Hörstegraben, a small drainage ditch that flows into the Rhin River, a tributary of the Havel. The Havel River flows through the Elbe basin and ultimately reaches the North Sea. The region includes several nature reserves and sensitive aquatic habitats that depend on good water quality. The plant's compliance with EU standards helps protect these ecosystems from nutrient pollution and other contaminants.
