SKA St Blasien OT Menzenschwand - Closed Wastewater Treatment Plant in St. Blasien, Germany

SKA St Blasien OT Menzenschwand was a wastewater treatment plant located in the Menzenschwand district of St. Blasien, in the Waldshut district of Baden-Württemberg, Germany. The plant served a small community of approximately 1,850 people before its closure. As a facility in the Black Forest region, it was part of Germany's decentralized wastewater infrastructure for rural areas. The plant's operational status is closed, and no treatment process or capacity details are available. Under German wastewater regulations, plants serving populations under 2,000 typically require secondary treatment or equivalent, in line with the EU Urban Waste Water Treatment Directive (91/271/EEC) for smaller agglomerations. The area drains into the Menzenschwander Alb river, a tributary of the Alb, which flows into the High Rhine near Albbruck. The High Rhine eventually joins the Rhine River, which flows into the North Sea. The Black Forest region is ecologically sensitive, supporting diverse aquatic life and forest ecosystems.
