Ortenburg OT Blindham Wastewater Treatment Plant, Bavaria, Germany

Ortenburg OT Blindham is a wastewater treatment plant located in the Lohfeld area of Unteriglbach, near Ortenburg in the Landkreis Passau district of Bavaria, Germany. The plant serves a population of about 8,982 people, placing it in the medium agglomeration category under EU regulations. As a German facility, the plant is subject to the EU Urban Waste Water Treatment Directive (91/271/EEC), which requires secondary treatment for agglomerations of this size. The plant's treatment processes are designed to meet national standards set by the German Water Resources Act (WHG) and the Wastewater Ordinance (AbwV). The treated effluent is discharged into the local watershed, which ultimately drains into the Danube River basin. The Danube flows through several countries before reaching the Black Sea, making the plant's operations important for downstream water quality and the ecological health of the Danube ecosystem.

The plant discharges into the Danube River basin, which flows through Central and Eastern Europe into the Black Sea. The local watershed supports diverse aquatic life and is part of a major migratory corridor for fish species. The plant's location inland, more than 50 km from the coast, means its discharge primarily affects freshwater ecosystems rather than marine environments.
