SKA Schönach Wastewater Treatment Plant, Kleinschönach, Baden-Württemberg
Kleinschönach, Baden-Württemberg, Germany
Overview
SKA Schönach is an advanced wastewater treatment plant serving Kleinschönach, Baden-Württemberg, Germany. It treats wastewater from around 2,050 people with a designed capacity of 2,400 m³/day.
SKA Schönach is an advanced wastewater treatment plant located in Kleinschönach, a locality within the municipality of Herdwangen-Schönach in Baden-Württemberg, Germany. The plant serves a population of approximately 2,050 people and has a designed capacity of 2,400 cubic meters per day, with an average discharge volume of about 519 m³/day. As an advanced treatment facility, SKA Schönach goes beyond secondary treatment to remove nutrients such as nitrogen and phosphorus, which is typical for plants in sensitive catchment areas under the EU Urban Waste Water Treatment Directive (91/271/EEC). For agglomerations of this size (2,000-10,000 population equivalent), the directive requires secondary treatment, but advanced treatment is mandated when discharging into sensitive areas like lakes or rivers feeding into the Danube or Rhine basins. The plant's treated effluent is discharged into local watercourses that ultimately drain into the Danube River basin, as the region lies on the European watershed. The Danube flows eastward through several countries before reaching the Black Sea, making the plant's nutrient removal crucial for protecting downstream ecosystems, including the Danube Delta, a vast wetland of international importance.
Environmental context
The plant discharges into small streams that feed into the Danube River basin, which flows through Central and Eastern Europe to the Black Sea. The region's karst geology and proximity to Lake Constance (Bodensee) watershed make nutrient control critical for preventing eutrophication in downstream lakes and the Danube Delta. Advanced treatment helps reduce nitrogen and phosphorus loads, protecting aquatic biodiversity and drinking water sources.
Frequently asked questions
SKA Schönach is located in Kleinschönach, a locality in the municipality of Herdwangen-Schönach, in the district of Sigmaringen, Baden-Württemberg, Germany.
The plant serves approximately 2,050 people in the Kleinschönach area.
The treated effluent is discharged into local streams that are part of the Danube River basin, ultimately flowing into the Black Sea.
SKA Schönach provides advanced treatment, which includes nutrient removal (nitrogen and phosphorus) beyond secondary treatment, as required for sensitive areas under the EU Urban Waste Water Treatment Directive.
Under the EU UWWTD, agglomerations of 2,000-10,000 population equivalent typically require secondary treatment. However, since the plant likely discharges into a sensitive area (Danube basin), advanced treatment is mandated to protect downstream water quality.
