KLA Rheinmünster Söllingen Wastewater Treatment Plant, Rheinmünster, Germany

KLA Rheinmünster Söllingen is a wastewater treatment facility located in the Söllingen district of Rheinmünster, Baden-Württemberg, Germany. The plant serves a population of around 5,350 residents, classifying it as a small agglomeration under EU regulations. As a German plant serving fewer than 10,000 people, it is subject to the EU Urban Waste Water Treatment Directive (91/271/EEC), which requires appropriate treatment before discharge. Plants of this scale typically employ secondary biological treatment to meet national and EU standards. The treated effluent is discharged into local watercourses that drain into the Rhine River basin, ultimately reaching the North Sea. The plant plays a key role in protecting the region's water quality and supporting the ecological health of the Rhine watershed.

The plant discharges into local streams that flow into the Rhine River, a major European waterway that drains into the North Sea. The Rhine basin supports diverse aquatic life and is an important migratory corridor for fish species. Protecting water quality in this basin is critical for downstream ecosystems and drinking water supplies.
