Dormagen Rheinfeld Wastewater Treatment Plant, Dormagen, Germany

The Dormagen Rheinfeld wastewater treatment plant is located in the Rheinfeld district of Dormagen, in the state of Nordrhein-Westfalen, Germany. It serves a population of approximately 85,000 residents, classifying it as a medium-to-large agglomeration under EU regulations. The plant is situated inland, near the Rhine River, and plays a key role in managing municipal wastewater for the area. As a German facility, the plant operates under the EU Urban Waste Water Treatment Directive (91/271/EEC), which requires secondary treatment for agglomerations with a population equivalent (PE) between 10,000 and 150,000. For larger agglomerations or those discharging into sensitive areas, tertiary treatment may be mandated. The plant's treatment processes are designed to meet these standards, ensuring compliance with national and European water quality regulations. The treated effluent is discharged into the Rhine River, one of Europe's major waterways, which flows through Germany and into the North Sea. The Rhine supports diverse aquatic life and is a critical water resource for millions of people. The plant's operations help protect the river's water quality and downstream ecosystems, including the Rhine Delta and the Wadden Sea, a UNESCO World Heritage site (though this designation is not named in the output).

The plant discharges into the Rhine River, which flows through Germany and the Netherlands before reaching the North Sea. The Rhine basin supports a wide range of aquatic species and is an important migratory corridor for fish. The plant's treatment helps reduce nutrient and pollutant loads, protecting downstream water quality and the ecological health of the river and its estuary.
