Breitengussbach Wastewater Treatment Plant, Unteroberndorf, Bavaria

The Breitengussbach wastewater treatment plant is located in Unteroberndorf, a district of Breitengüßbach in the Landkreis Bamberg, Bavaria, Germany. It serves a population of 2,265 and operates with advanced treatment technology, ensuring high-quality effluent. The plant has a designed capacity of 6,850 m³/day and currently discharges an average of 787.51 m³/day of treated wastewater. As a German facility, the plant operates under the EU Urban Waste Water Treatment Directive (91/271/EEC), which requires secondary treatment for agglomerations of this size. The advanced treatment level indicates that the plant likely employs nutrient removal or other tertiary processes to meet stringent effluent standards, particularly relevant for sensitive areas within the Danube or Rhine basins. The treated effluent is discharged into a local water body that ultimately drains into the Main River, a major tributary of the Rhine. The Rhine basin supports diverse aquatic ecosystems and is a critical water resource for the region. The plant's advanced treatment helps protect downstream water quality and ecological health.

The plant discharges into a local watercourse that flows into the Main River, which joins the Rhine near Mainz. The Rhine basin is a vital ecological corridor supporting diverse fish species, including salmon and eel, and is subject to strict water quality regulations under the EU Water Framework Directive. The advanced treatment at Breitengussbach helps reduce nutrient loading and protect downstream habitats.
