Overath Wastewater Treatment Plant: Serving Overath, Nordrhein-Westfalen, Germany

The Overath wastewater treatment plant is located in the town of Overath, within the Rheinisch-Bergischer Kreis district of Nordrhein-Westfalen, Germany. The facility serves a population of around 14,184, classifying it as a medium-sized agglomeration under European Union regulations. As a German plant, Overath 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 stringent treatment if the receiving waters are designated as sensitive areas. The regulatory framework ensures compliance with national and EU standards. The treated effluent from the Overath plant is discharged into local watercourses that ultimately drain into the Rhine River basin. The Rhine is a major European waterway supporting diverse aquatic ecosystems and providing drinking water for millions. The plant plays a key role in protecting the local watershed and downstream environments from nutrient pollution and other contaminants.

The Overath plant discharges into small streams that flow into the Agger River, a tributary of the Sieg River, which joins the Rhine River near Bonn. The Rhine basin is ecologically significant, supporting migratory fish species such as salmon and eel, and providing habitat for diverse aquatic life. The plant's operations help maintain water quality in this important river system, which ultimately drains into the North Sea.
