Pleiskirchen Wastewater Treatment Plant: Serving Pleiskirchen, Bavaria, Germany

The Pleiskirchen wastewater treatment plant is located in the municipality of Pleiskirchen in the Altötting district of Bavaria, Germany. It serves a population of approximately 2,645, classifying it as a small agglomeration under the EU Urban Waste Water Treatment Directive (91/271/EEC). The plant is situated inland, away from coastal areas, and treats wastewater from the local community. The plant provides secondary treatment, which is the minimum required by the EU directive for freshwater discharges from agglomerations of this size. The designed capacity is 1,350 m³/day, with an actual discharge volume of 669.39 m³/day, indicating operational capacity well within design limits. As a German facility, it operates under the national Wasserhaushaltsgesetz (Water Resources Act) and relevant state regulations, ensuring compliance with EU standards. The treated effluent is discharged into local watercourses that eventually drain into the Danube River basin, contributing to the Black Sea watershed. The plant plays a key role in protecting the local aquatic environment, including streams and rivers in the Bavarian region, by reducing organic load and nutrients before discharge.

The plant discharges into small streams that flow into the Inn River, a major tributary of the Danube. The Danube ultimately drains into the Black Sea. The local watershed supports diverse aquatic life, including fish species such as brown trout and grayling. The plant's secondary treatment helps protect downstream water quality in this ecologically sensitive river system.
