Bad Honnef Aegidienberg Wastewater Treatment Plant, Nordrhein-Westfalen, Germany

The Bad Honnef Aegidienberg wastewater treatment plant is located in the Aegidienberg district of Bad Honnef, in the state of Nordrhein-Westfalen, Germany. It serves a population equivalent of 8,740, classifying it as a small to medium agglomeration under the EU Urban Waste Water Treatment Directive (91/271/EEC). The plant is situated near the Kochenbachtalbrücke bridge along the A3 motorway. As a German facility serving fewer than 10,000 people, the plant is required to provide secondary treatment or equivalent under the EU directive. Germany implements this through the Abwasserverordnung (Wastewater Ordinance), which sets strict effluent standards. The plant's treatment process and capacity details are not publicly available, but it is expected to meet national standards for biological treatment. The plant discharges into the local water system, which ultimately drains into the Rhine River via smaller tributaries. The Rhine is a major European waterway and ecologically significant river, supporting diverse aquatic life and serving as a migratory corridor for fish. The plant's operations contribute to protecting the Rhine's water quality and the downstream environment.

The plant's treated effluent enters the local drainage network, which flows into the Rhine River basin. The Rhine is a critical waterway in Europe, supporting diverse aquatic ecosystems and providing drinking water for millions. The plant's location in the Sieg River sub-basin means its discharge affects local streams before reaching the Rhine. Protecting this watershed is essential for maintaining water quality in the Rhine delta and the North Sea.
