Niemegk Wastewater Treatment Plant, Planetal, Brandenburg

The Niemegk wastewater treatment plant is located in Planetal, near the town of Niemegk, in the Brandenburg region of Germany. It serves a population of approximately 3,403 people, classifying it as a small 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 sensitive areas. With a designed capacity of 4,700 m³/day and a current discharge volume of 345.21 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 Elbe River basin, which flows into the North Sea. The plant's advanced treatment helps protect downstream aquatic ecosystems, including the Elbe's diverse fish populations and migratory bird habitats.

The plant discharges into local streams that are part of the Elbe River basin, which flows through Germany and into the North Sea. The Elbe supports diverse aquatic life, including salmon and sturgeon, and its estuary is an important migratory corridor for birds. Advanced treatment at this plant reduces nutrient loads, helping to prevent eutrophication in downstream waters.
