Hausen_Wurzburg OT Rieden Wastewater Treatment Plant, Rieden, Bavaria

Hausen_Wurzburg OT Rieden is an advanced wastewater treatment plant located in the Rieden district of Hausen bei Würzburg, in Bavaria, Germany. The plant serves a population of approximately 2,747 residents and is part of the municipal infrastructure managed by the local authorities. The plant employs advanced treatment processes, which go beyond secondary treatment to remove nutrients and other pollutants. With a designed capacity of 3,800 m³/day and a current discharge volume of 495.34 m³/day, the facility operates well below its capacity, indicating room for future growth. As a German plant, it operates under the EU Urban Waste Water Treatment Directive (91/271/EEC), which mandates advanced treatment for sensitive areas and large agglomerations. The treated effluent is discharged into local water bodies that eventually drain into the Main River, a major tributary of the Rhine. The Rhine basin supports diverse aquatic life and is an important ecological corridor in Europe. The plant's advanced treatment helps protect downstream water quality and contributes to the health of the Rhine ecosystem.

The plant discharges into local streams that flow into the Main River, which joins the Rhine near Mainz. The Rhine is a major European waterway supporting diverse fish species and migratory birds. The advanced treatment at this plant reduces nutrient loading, helping to prevent eutrophication in downstream waters and maintaining the ecological balance of the Rhine basin.
