Roggenburg Biberach Wastewater Treatment Plant - Biberach, Bavaria

Roggenburg Biberach is an advanced wastewater treatment plant located in the town of Biberach, within the municipality of Roggenburg in the Landkreis Neu-Ulm district of Bavaria, Germany. The plant serves a population of approximately 2,480 residents, reflecting its role in managing domestic wastewater for this small community. As an advanced treatment facility, Roggenburg Biberach goes beyond secondary treatment to remove nutrients such as nitrogen and phosphorus, which is typical for plants in sensitive catchment areas under the EU Urban Waste Water Treatment Directive (91/271/EEC). The plant has a designed capacity of 3,100 m³/day, with a current discharge volume of about 628 m³/day, indicating operational headroom. The treated effluent is discharged into local watercourses that ultimately drain into the Danube River basin. The plant's advanced treatment helps protect downstream water quality in the Danube catchment, supporting aquatic ecosystems and reducing nutrient loads that could contribute to eutrophication in the Black Sea.

The plant discharges into the Danube River basin, which flows southeast through several countries before reaching the Black Sea. The Danube supports diverse aquatic life and is an important migratory corridor for fish species. Advanced treatment at this plant helps reduce nutrient pollution, protecting downstream ecosystems from eutrophication.
