SKA Bohringen AZV Unteres Schlichemtal Wastewater Treatment Plant, Irslingen, Germany

SKA Bohringen AZV Unteres Schlichemtal is a wastewater treatment plant located in Irslingen, a district of Dietingen in the Rottweil region of Baden-Württemberg, Germany. The plant serves a population of approximately 5,878 people, classifying it as a small to medium agglomeration under 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 is part of the AZV Unteres Schlichemtal, a wastewater association managing treatment in the lower Schlichem valley. The regulatory framework ensures compliance with national and EU standards. The plant discharges treated effluent into the local watershed, which ultimately drains into the Schlichem River, a tributary of the Neckar River. The Neckar flows into the Rhine, one of Europe's major waterways. The plant plays a key role in protecting the Schlichem and downstream aquatic ecosystems from nutrient pollution and organic loads.

The plant's treated effluent enters the Schlichem River, a small tributary of the Neckar, which flows into the Rhine River. The Rhine basin supports diverse aquatic life and is an important migratory corridor for fish. The plant's operations help maintain water quality in this ecologically sensitive region, reducing nutrient loads that could otherwise contribute to eutrophication in downstream waters.
