KA BUBACH CALMESWEILER Wastewater Treatment Plant, Eppelborn, Saarland

KA BUBACH CALMESWEILER is a municipal wastewater treatment plant located in the Bubach-Calmesweiler district of Eppelborn, in the Saarland region of Germany. The plant serves a population of approximately 23,750 people, classifying it as a medium-sized agglomeration under EU regulations. As a German facility, the plant operates under the EU Urban Waste Water Treatment Directive (91/271/EEC), which mandates secondary treatment for agglomerations of this size. The directive also requires appropriate treatment before discharge into inland waters, ensuring compliance with national water quality standards. The plant discharges treated wastewater into local watercourses that flow into the Saar River, a tributary of the Moselle and ultimately the Rhine. This river system supports diverse aquatic life and is an important ecological corridor in western Germany. The plant's operation helps protect downstream water quality in the Saar and Rhine basins.

The plant discharges into local streams that feed the Saar River, which flows into the Moselle and then the Rhine. The Rhine basin is a major European waterway supporting diverse ecosystems, including fish species such as salmon and eel. The plant's treatment helps maintain water quality in this ecologically sensitive river system.
