Friedland Wastewater Treatment Plant, Brandenburg, Germany

The Friedland wastewater treatment plant is located in the town of Friedland, in the Oder-Spree district of Brandenburg, Germany. It serves a population of approximately 5,513 residents, classifying it as a small agglomeration under German and EU regulations. The plant employs advanced treatment processes, which go beyond the secondary treatment required by the EU Urban Waste Water Treatment Directive (91/271/EEC) for sensitive areas. With a designed capacity of 7,500 m³/day and a current discharge volume of 423.13 m³/day, the facility operates well below its capacity, indicating room for future growth or seasonal variations. The treated effluent is discharged into local water bodies that eventually drain into the Spree River and then the Havel River, which flows into the Elbe and ultimately the North Sea. The plant's advanced treatment helps protect the sensitive aquatic ecosystems of the Spreewald region and downstream waters.

The plant discharges into the local watershed that feeds the Spree River, a key tributary of the Havel River. The Spree River flows through the Spreewald biosphere reserve, an ecologically sensitive area known for its floodplain forests and diverse aquatic life. Downstream, the Havel joins the Elbe, which drains into the North Sea. The advanced treatment ensures minimal nutrient and pollutant loading, supporting the ecological health of these water bodies.
