SKA Klettgau OTGeisslingen Wastewater Treatment Plant, Geißlingen, Baden-Württemberg

SKA Klettgau OTGeisslingen is a wastewater treatment plant located in Geißlingen, a district of Klettgau in the Waldshut district of Baden-Württemberg, Germany. The plant serves a population of approximately 3,950 people, placing it in the small agglomeration category under German and EU regulations. As a German plant, it operates under the EU Urban Waste Water Treatment Directive (91/271/EEC), which requires secondary treatment for agglomerations of this size. The plant's treatment processes and capacity are managed to meet national standards set by the Wasserhaushaltsgesetz (WHG) and relevant state regulations. The plant discharges treated effluent into the local watershed, which ultimately drains into the Rhine River via smaller tributaries. The Rhine is a major European waterway that flows into the North Sea, supporting diverse aquatic ecosystems and providing drinking water for millions of people downstream.

The plant's treated effluent enters the local water system, which flows through the Klettgau region and eventually reaches the Rhine River. The Rhine basin is ecologically significant, supporting diverse fish species, migratory birds, and riparian habitats. Downstream, the Rhine discharges into the North Sea, a critical marine environment. The plant's operations help protect water quality in this transboundary river system.
