Rehfelde Wastewater Treatment Plant | Brandenburg, Germany

Rehfelde wastewater treatment plant is located in the town of Rehfelde, in the Märkisch-Oderland district of Brandenburg, Germany. The plant serves a population of approximately 4,574, classifying it as a small to medium agglomeration under German and EU regulations. The plant employs advanced treatment processes, which go beyond the secondary treatment standard required by the EU Urban Waste Water Treatment Directive (91/271/EEC) for agglomerations of this size. Its designed capacity is 3,400 m³/day, with an actual discharge volume of 319.82 m³/day, indicating significant reserve capacity. The treated effluent is discharged into local watercourses that drain into the Baltic Sea via the Oder River system. The plant plays a key role in protecting the region's surface waters, which support diverse aquatic life and are part of the broader Oder estuary ecosystem.

The plant discharges into local streams that flow into the Oder River, which ultimately reaches the Baltic Sea. The Oder estuary is an ecologically sensitive area that supports diverse aquatic life and serves as an important migratory corridor for fish. Advanced treatment helps reduce nutrient loading, protecting downstream waters from eutrophication.
