Vohringen Wastewater Treatment Plant, Vöhringen, Bavaria, Germany

The Vohringen wastewater treatment plant is located in Vöhringen, a town in the Bavarian district of Neu-Ulm, Germany. Serving a population of around 23,000, the plant is part of the region's municipal wastewater infrastructure, handling domestic and industrial flows from the community. 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 (10,000-100,000 population equivalent). The directive also mandates more stringent treatment if the receiving waters are designated as sensitive areas. The plant's treatment process and capacity details are not publicly available, but it is expected to meet national standards set by the German Water Resources Act (WHG) and state-level regulations. The treated effluent is discharged into the Iller River, which flows northward through Bavaria and joins the Danube near Ulm. The Danube then carries the water through several countries to the Black Sea. The Iller and Danube rivers support diverse aquatic life and are important for regional ecology and water supply. The plant's location in the Danube basin means its discharge contributes to the overall water quality of this major European river system.

The Vohringen plant discharges into the Iller River, a right-bank tributary of the Danube. The Iller flows through the Allgäu region and joins the Danube near Ulm. The Danube then travels over 2,800 km to the Black Sea, passing through multiple countries. The river system supports diverse fish populations, including migratory species, and provides drinking water for millions. The plant's effluent quality is critical for maintaining the ecological health of the Iller and downstream Danube waters.
