SKA AZV UNTERE ELZ KONDINGEN Wastewater Treatment Plant, Köndringen, Germany

SKA AZV UNTERE ELZ KONDINGEN is a wastewater treatment plant located in Köndringen, a district of Teningen in the Emmendingen district of Baden-Württemberg, Germany. The plant serves a population of approximately 45,750, classifying it as a medium to large agglomeration under EU standards. As a German facility, the plant is subject to the EU Urban Waste Water Treatment Directive (91/271/EEC), which requires secondary treatment for agglomerations of this size. The plant's treatment processes are designed to meet the stringent effluent standards set by German water law, which implements the directive's requirements for biological treatment and nutrient removal where necessary. The plant discharges treated wastewater into the local water system, which ultimately drains into the Elz River, a tributary of the Rhine. The Rhine basin is a major European watershed supporting diverse aquatic life and providing drinking water for millions. The plant's operations help protect the ecological health of the Elz and Rhine rivers by reducing nutrient and pollutant loads.

The plant's treated effluent enters the Elz River, which flows into the Rhine River near the border with France. The Rhine is one of Europe's most important waterways, supporting a rich ecosystem including migratory fish species such as salmon and eel. The plant's location in the Upper Rhine Plain means its discharge contributes to the overall water quality of the Rhine basin, which is subject to international agreements like the Rhine Action Programme to reduce pollution.
