Overview
Einhaus wastewater treatment plant in Schleswig-Holstein, Germany, serves about 5,300 people with advanced treatment. It discharges treated water into local waterways within the Elbe basin.
The Einhaus wastewater treatment plant is located in the municipality of Einhaus, in the Herzogtum Lauenburg district of Schleswig-Holstein, Germany. It serves a population of approximately 5,300, placing it in the medium agglomeration category under German and EU regulations. The plant is situated inland, about 10-50 km from the Baltic Sea coast. The facility 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. Advanced treatment typically includes nutrient removal (nitrogen and phosphorus) to protect sensitive water bodies. The plant has a designed capacity of 8,400 m³/day and currently treats an average daily volume of about 759 m³, indicating significant reserve capacity. The treated effluent is discharged into local streams that flow into the Stepenitz River, a tributary of the Trave River, which eventually reaches the Baltic Sea near Lübeck. This discharge contributes to the overall water quality in the Trave basin, supporting aquatic ecosystems and recreational uses. The advanced treatment helps minimize nutrient loading, reducing the risk of eutrophication in the Baltic Sea.
Environmental context
The plant discharges into small watercourses that drain into the Stepenitz River, part of the Trave River system, which flows into the Baltic Sea. The Baltic Sea is a brackish, semi-enclosed sea sensitive to nutrient pollution, making advanced treatment crucial for protecting its ecological balance. The surrounding region includes lakes and wetlands that support diverse aquatic life and migratory birds.
Frequently asked questions
The Einhaus plant is located in the municipality of Einhaus, in the Herzogtum Lauenburg district of Schleswig-Holstein, Germany, near the town of Ratzeburg.
The plant serves approximately 5,314 people, classifying it as a medium-sized agglomeration under EU regulations.
The treated effluent is discharged into local streams that flow into the Stepenitz River, a tributary of the Trave River, which eventually reaches the Baltic Sea.
The plant provides advanced treatment, which includes nutrient removal (nitrogen and phosphorus) beyond the secondary treatment standard required by the EU Urban Waste Water Treatment Directive.
As a German plant serving over 2,000 people, it operates under the EU Urban Waste Water Treatment Directive (91/271/EEC), which mandates secondary treatment as a minimum. The advanced treatment here exceeds requirements, likely due to the sensitivity of the Baltic Sea receiving waters.
