Overview
Berkenthin wastewater treatment plant in Schleswig-Holstein, Germany serves about 3,800 people with advanced treatment. It discharges treated water into the local watershed, contributing to the Elbe River basin.
The Berkenthin wastewater treatment plant is located in the municipality of Berkenthin, in the district of Kreis Herzogtum Lauenburg, Schleswig-Holstein, Germany. It serves a population of approximately 3,800, placing it in the small agglomeration category under the EU Urban Waste Water Treatment Directive (UWWTD). The plant is situated near the Elbe-Lübeck Canal and drains into the broader Elbe River system. The plant employs advanced treatment, which goes beyond the EU UWWTD's minimum requirement of secondary treatment for agglomerations of this size. Advanced treatment typically includes nutrient removal (nitrogen and phosphorus) to protect sensitive water bodies. The designed capacity is 4,800 cubic meters per day, with a reported discharge volume of 460.45 cubic meters per day, indicating operational headroom. The treated effluent is discharged into local watercourses that flow into the Elbe River, eventually reaching the North Sea. The plant's advanced treatment helps reduce nutrient loading in the Elbe basin, supporting water quality and aquatic ecosystems downstream. Its location within 50 km of the coast underscores the importance of nutrient control to prevent eutrophication in coastal waters.
Environmental context
The plant discharges into the Elbe River basin, which flows through northern Germany into the North Sea. The Elbe estuary supports diverse aquatic life and is an important migratory corridor for fish. Advanced treatment at this plant reduces nutrient loads, helping to mitigate eutrophication risks in the downstream coastal environment.
Frequently asked questions
The Berkenthin wastewater treatment plant is located in the municipality of Berkenthin, in the district of Kreis Herzogtum Lauenburg, Schleswig-Holstein, Germany.
The plant serves approximately 3,800 people, classifying it as a small agglomeration under the EU Urban Waste Water Treatment Directive.
The plant discharges treated effluent into local watercourses that flow into the Elbe River basin, ultimately reaching the North Sea.
The plant provides advanced treatment, which includes nutrient removal beyond the EU UWWTD's secondary treatment requirement for its size.
Under the EU UWWTD, agglomerations of this size require at least secondary treatment. Berkenthin exceeds this with advanced treatment, likely due to its location in a sensitive area or to meet local water quality standards.
