SKA Herrischried Murgtal Wastewater Treatment Plant, Hogschür, Baden-Württemberg

SKA Herrischried Murgtal is a municipal wastewater treatment plant located in Hogschür, a district of Herrischried in the Waldshut district of Baden-Württemberg, Germany. The plant serves a population of approximately 2,600 and has a designed capacity of 3,300 cubic meters per day, with an average discharge volume of 636.41 cubic meters per 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. Advanced treatment typically includes nutrient removal (nitrogen and phosphorus) to protect sensitive receiving waters, aligning with Germany's implementation of the directive for sensitive areas. The treated effluent is discharged into the local watershed, which ultimately drains into the Rhine River via the Murg River. The Rhine is a major European waterway supporting diverse aquatic ecosystems and providing drinking water for millions. The plant's advanced treatment helps maintain water quality in this ecologically significant basin.

The plant discharges into the Murg River, a tributary of the Rhine River, which flows through the Black Forest region before joining the Rhine near Basel. The Rhine is a vital ecological corridor supporting diverse fish species, including salmon, and provides drinking water for downstream communities. Advanced treatment at this plant helps reduce nutrient loading, protecting the Rhine's water quality and its role as a major European waterway.
