Overview
SKA Grafenhausen is an advanced wastewater treatment plant in Grafenhausen, Baden-Württemberg, Germany, serving approximately 3,100 people with a designed capacity of 4,500 m³/day.
SKA Grafenhausen is a municipal wastewater treatment facility located in Grafenhausen, within the Waldshut district of Baden-Württemberg, Germany. The plant serves a population of around 3,100 residents and has a designed capacity of 4,500 cubic meters per day, with an average discharge volume of 885.11 m³/day. As an advanced treatment plant, SKA Grafenhausen goes beyond secondary treatment to remove nutrients such as nitrogen and phosphorus, ensuring high-quality effluent. This level of treatment is typical for plants in sensitive catchment areas under the EU Urban Waste Water Treatment Directive (91/271/EEC), which requires advanced treatment for agglomerations discharging into sensitive areas. The treated effluent is discharged into local watercourses that eventually drain into the Rhine River basin. The Rhine is a major European waterway supporting diverse aquatic life and providing drinking water for millions. The plant's advanced treatment helps protect downstream ecosystems and water quality in the region.
Environmental context
SKA Grafenhausen discharges into small streams in the Upper Schlüchttal valley, which flow into the Schlücht River, a tributary of the Wutach River. The Wutach ultimately joins the Rhine River near the Swiss border. The Rhine basin is ecologically sensitive, supporting species such as Atlantic salmon and migratory fish. Advanced treatment at this plant reduces nutrient loading, helping to prevent eutrophication in downstream waters.
