Redange_Attert Wastewater Treatment Plant, Redange-sur-Attert, Luxembourg

The Redange_Attert wastewater treatment plant is located in Redange-sur-Attert, in the Canton of Redange, Luxembourg. It serves a population equivalent of 4,076, classifying it as a small agglomeration under EU regulations. The plant is situated inland, away from coastal areas, and its operations are part of Luxembourg's municipal wastewater infrastructure. As a facility serving fewer than 10,000 people, the plant is subject to the EU Urban Waste Water Treatment Directive 91/271/EEC, which requires appropriate treatment for discharges into freshwater bodies. For small agglomerations, secondary treatment is typically expected to ensure adequate removal of organic matter and nutrients. The regulatory framework provides the operational context. The treated effluent from the plant is discharged into the Attert River, a tributary of the Alzette River, which flows into the Sauer River and eventually the Moselle River, a major tributary of the Rhine. The Rhine basin is ecologically significant, supporting diverse aquatic life and serving as an important migratory corridor for fish species. The plant's discharge contributes to the water quality of this transboundary river system.

The Redange_Attert plant discharges into the Attert River, which flows into the Alzette, then the Sauer, and finally the Moselle River, part of the Rhine basin. This watershed supports diverse aquatic ecosystems and is an important migratory corridor for fish. The plant's operations help protect water quality in this ecologically sensitive transboundary river system.
