Wuazv Rezatal Wastewater Treatment Plant, Mühlstetten, Bayern

Wuazv Rezatal is a wastewater treatment plant located in Mühlstetten, a district of Röttenbach in the Landkreis Roth, Bayern, Germany. The plant serves a population of approximately 3,920 and is classified as a small agglomeration under EU regulations. The plant provides advanced treatment, which goes beyond the secondary treatment required by the EU Urban Waste Water Treatment Directive (91/271/EEC) for agglomerations of this size. Its designed capacity is 4,900 m³/day, with a reported discharge volume of 992.06 m³/day, indicating operational headroom. The treated effluent is discharged into local water bodies that ultimately drain into the Rhine basin via the Rednitz and Main rivers. The plant plays a key role in protecting the water quality of the region's streams and the downstream aquatic ecosystems.

The plant discharges into the local watershed, which flows into the Rednitz River, a tributary of the Main, and eventually into the Rhine. This region is part of the Rhine basin, a major European river system supporting diverse aquatic life and providing drinking water for millions. The advanced treatment helps reduce nutrient loads and protect downstream habitats from eutrophication.
