Overview
Rieseby wastewater treatment plant in Schleswig-Holstein, Germany, serves 1,758 people with advanced treatment. The plant is now closed, having discharged into the Baltic Sea catchment.
The Rieseby wastewater treatment plant is located in the municipality of Rieseby, in the district of Rendsburg-Eckernförde, Schleswig-Holstein, Germany. It served a population of 1,758 people and is now closed. The plant was situated near the Schlei inlet, a brackish water body connected to the Baltic Sea. The plant provided advanced treatment, which exceeds the secondary treatment standard required by the EU Urban Waste Water Treatment Directive (91/271/EEC) for agglomerations of this size. Its designed capacity was 2,500 cubic meters per day, and the average discharge volume was 444.91 cubic meters per day. The plant operated under German water law, which implements the EU directive and requires permits for discharge into sensitive water bodies. The treated effluent was discharged into the Schlei-Ostsee catchment, ultimately reaching the Baltic Sea. The Baltic Sea is a sensitive marine environment with eutrophication challenges, making advanced nutrient removal important for coastal water quality.
Environmental context
The plant discharged into the Schlei inlet, a narrow brackish water body that flows into the Eckernförde Bay and then the Baltic Sea. The Baltic Sea is a semi-enclosed sea with limited water exchange, making it vulnerable to nutrient pollution. Advanced treatment at this plant helped reduce nitrogen and phosphorus loads, supporting efforts to combat eutrophication in the region.
Frequently asked questions
The plant is located in Rieseby, in the district of Rendsburg-Eckernförde, Schleswig-Holstein, Germany, near the Schlei inlet.
The plant served a population of 1,758 people.
The plant provided advanced treatment, which includes nutrient removal beyond secondary treatment.
Under the EU UWWTD, agglomerations with a population equivalent above 2,000 require secondary treatment. Although Rieseby served fewer than 2,000 people, it provided advanced treatment, likely due to discharge into a sensitive area like the Baltic Sea catchment.
The plant discharged into the Schlei inlet, which flows into the Baltic Sea. The Baltic Sea is sensitive to eutrophication, so advanced treatment helped reduce nutrient loads.
