Waldbrunn Westerwald _ Lahr Wastewater Treatment Plant, Lahr, Hessen

The Waldbrunn Westerwald _ Lahr wastewater treatment plant is located in the town of Lahr, within the Waldbrunn (Westerwald) municipality in Hessen, Germany. This facility serves a population of approximately 2,834 residents, operating as a key component of the region's sanitation infrastructure. The plant employs advanced treatment processes, ensuring a high level of effluent quality. With a designed capacity of 3,275 m³/day and an actual discharge volume of 969.05 m³/day, it operates well below its capacity. As a German facility, it complies with the EU Urban Waste Water Treatment Directive (91/271/EEC), which mandates advanced treatment for sensitive areas and secondary treatment for all discharges. The treated effluent is discharged into local water bodies that ultimately drain into the Rhine River basin, a major European watershed. The plant's advanced treatment helps protect downstream aquatic ecosystems and supports the ecological health of the region's waterways.

The plant discharges into local streams that flow into the Lahn River, a tributary of the Rhine. The Rhine basin is ecologically significant, supporting diverse aquatic life and serving as a migratory corridor for fish species. Advanced treatment at this plant reduces nutrient loading, helping to prevent eutrophication in downstream waters.
