KA WUSTWEILER Wastewater Treatment Plant, Illingen, Saarland, Germany

KA WUSTWEILER is a municipal wastewater treatment plant located in the Wustweiler district of Illingen, in the Saarland state of Germany. The plant serves a population of approximately 40,700 people, placing it in the medium agglomeration category under EU regulations. It is situated inland, away from coastal areas, and contributes to the local water management system. As a German plant serving over 10,000 population equivalents, KA WUSTWEILER operates under the EU Urban Waste Water Treatment Directive 91/271/EEC, which requires secondary treatment as a minimum standard. For agglomerations of this size, the directive also mandates appropriate treatment to meet quality standards for receiving waters. The plant's treatment processes are designed to comply with these regulatory requirements, ensuring effective pollutant removal. The treated effluent from KA WUSTWEILER is discharged into local watercourses that ultimately drain into the Saar River basin. The Saar River flows through the region and joins the Moselle, a major tributary of the Rhine. This river system supports diverse aquatic life and is important for regional ecology and water quality management. The plant plays a key role in protecting these downstream waters from pollution.

KA WUSTWEILER discharges treated wastewater into local streams that feed into the Saar River basin. The Saar River flows through Saarland and into the Moselle, which joins the Rhine before reaching the North Sea. This river network supports diverse aquatic ecosystems, including fish populations and macroinvertebrate communities. The plant's operations help maintain water quality in this ecologically sensitive watershed, which is subject to EU water quality standards.
