Schleiden Wastewater Treatment Plant, Schleiden, Nordrhein-Westfalen, Germany

The Schleiden wastewater treatment plant is located in the town of Schleiden, in the Kreis Euskirchen district of Nordrhein-Westfalen, Germany. The facility serves a population of approximately 20,933 people, classifying it as a medium-sized 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 directive also mandates more advanced treatment if the receiving waters are designated as sensitive areas. The regulatory framework ensures compliance with national and EU standards. The plant discharges treated wastewater into the local water system, which ultimately drains into the Olef River, a tributary of the Rur River. The Rur flows into the Meuse River, which reaches the North Sea. The plant plays a key role in protecting the water quality of the Olef and downstream ecosystems, supporting aquatic life and recreational uses.
