KA Rehden - Advanced Wastewater Treatment Plant in Rehden, Niedersachsen

KA Rehden is an advanced wastewater treatment plant located in Rehden, a municipality in the Samtgemeinde Rehden, Landkreis Diepholz, Niedersachsen, Germany. The plant serves a population of approximately 6,361 people and has a designed capacity of 12,000 cubic meters per day, with an actual discharge volume of 765.03 cubic meters per day. As an advanced treatment facility, KA Rehden goes beyond secondary treatment to remove nutrients such as nitrogen and phosphorus, which is typical for plants in sensitive areas under the EU Urban Waste Water Treatment Directive (91/271/EEC). The directive requires tertiary treatment for agglomerations of this size if they discharge into sensitive areas, which is likely the case given the plant's advanced status. The treated effluent is discharged into local water bodies that ultimately drain into the Weser River basin. The Weser flows northward through Niedersachsen and into the North Sea. The plant's advanced treatment helps protect the ecological health of these waters, supporting aquatic life and reducing nutrient pollution in the downstream environment.

KA Rehden discharges into the local watershed that is part of the Weser River basin. The Weser flows through Niedersachsen and empties into the North Sea. The region's waters support diverse aquatic life and are important for migratory fish species. Advanced treatment at the plant reduces nutrient loads, helping to prevent eutrophication in downstream lakes and coastal areas.
