Dahme Wastewater Treatment Plant, Dahme/Mark, Brandenburg, Germany

The Dahme wastewater treatment plant is located in Dahme/Mark, a town in the Teltow-Fläming district of Brandenburg, Germany. The facility serves a population of 8,334 and is part of the municipal wastewater infrastructure for the region. The plant provides advanced treatment, which goes beyond the secondary treatment required by the EU Urban Waste Water Treatment Directive (91/271/EEC) for agglomerations of this size. With a designed capacity of 7,500 m³/day and an average discharge volume of 701.37 m³/day, the plant operates well below its capacity, indicating room for future growth. The treated effluent is discharged into local watercourses that eventually drain into the Elbe River basin, which flows into the North Sea. The plant's advanced treatment helps protect the sensitive aquatic ecosystems of the region, including the Dahme River and its tributaries, which support diverse freshwater life.

The plant discharges into the Dahme River, a tributary of the Spree River, which flows into the Havel and then the Elbe River before reaching the North Sea. The region's watershed supports diverse aquatic habitats and is important for migratory fish species. Advanced treatment helps reduce nutrient loading, protecting downstream water quality in the Elbe estuary.
