Lunow Wastewater Treatment Plant, Brandenburg, Germany

The Lunow wastewater treatment plant is located in the municipality of Lunow-Stolzenhagen, in the Barnim district of Brandenburg, Germany. It serves a population of approximately 4,578 people, placing it in the small agglomeration category under the EU Urban Waste Water Treatment Directive (UWWTD). The plant is situated inland, away from coastal areas, and its operations are part of the regional water management infrastructure in northeastern Germany. The plant employs advanced treatment processes, which go beyond the secondary treatment standard required by the EU UWWTD for agglomerations of this size. Advanced treatment typically includes nutrient removal (nitrogen and phosphorus) to protect sensitive water bodies. The designed capacity of 7,000 cubic meters per day indicates that the plant has room for future growth, with current discharge volumes at about 394.52 cubic meters per day, reflecting a utilization rate well below capacity. The treated effluent from the Lunow plant is discharged into local watercourses that eventually drain into the Oder River basin. The Oder River flows northward to the Baltic Sea, passing through ecologically significant areas such as the Lower Oder Valley National Park. The advanced treatment helps reduce nutrient loading, which is critical for preventing eutrophication in the Baltic Sea, a sensitive marine environment.

The Lunow plant discharges into the Oder River basin, which flows into the Baltic Sea via the Szczecin Lagoon. The Baltic Sea is a semi-enclosed, brackish sea highly sensitive to nutrient pollution, making advanced treatment essential for reducing nitrogen and phosphorus loads. The region supports diverse aquatic life and migratory fish species, and the Oder River is an important ecological corridor in northeastern Germany.
