SKA Braunsbach Dottingen Wastewater Treatment Plant, Döttingen, Baden-Württemberg

SKA Braunsbach Dottingen is a municipal wastewater treatment plant located in Döttingen, a district of Braunsbach in the Schwäbisch Hall district of Baden-Württemberg, Germany. The plant serves a population of approximately 3,700 and has a designed capacity of 3,500 cubic meters per day, with an average discharge volume of 899.33 m³/day. The plant employs advanced treatment processes, which go beyond the secondary treatment required by the EU Urban Waste Water Treatment Directive (91/271/EEC) for agglomerations of this size. In Germany, advanced treatment typically includes nutrient removal (nitrogen and phosphorus) to protect sensitive water bodies, aligning with the country's high environmental standards. The treated effluent is discharged into a local watercourse that ultimately drains into the Kocher River, a tributary of the Neckar, which flows into the Rhine River and then the North Sea. The plant plays a key role in maintaining water quality in the region, supporting aquatic life and downstream ecosystems.

The plant discharges into a small stream that flows into the Kocher River, part of the Rhine basin. The Kocher River supports diverse aquatic life and is an important corridor for migratory fish. The advanced treatment ensures minimal nutrient loading, protecting the river's ecological health and the downstream Rhine ecosystem.
