Rott_Inn Wastewater Treatment Plant, Rott am Inn, Bayern, Germany

Rott_Inn is a municipal wastewater treatment plant located in Rott am Inn, in the district of Rosenheim, Bayern, Germany. The plant serves a population of approximately 3,967 and has a designed capacity of 4,250 cubic meters per day, with an average discharge volume of 807.22 cubic meters per day. The plant provides secondary treatment, which is the standard biological treatment required under the EU Urban Waste Water Treatment Directive (91/271/EEC) for agglomerations of this size. Secondary treatment typically involves biological processes to reduce organic matter and suspended solids, ensuring compliance with European effluent standards. The treated effluent is discharged into the local water environment, which ultimately drains into the Inn River, a major tributary of the Danube. The Danube flows into the Black Sea, making this plant part of a large international river basin. The plant's operation helps protect the water quality of the Inn and downstream ecosystems, including the Danube Delta, a region of high ecological importance.

The plant discharges into the Inn River, which flows into the Danube River and eventually reaches the Black Sea. The Inn is a significant alpine river supporting diverse aquatic life, including fish species such as grayling and brown trout. The downstream Danube Delta is a vast wetland ecosystem that provides critical habitat for migratory birds and numerous fish species. Effective wastewater treatment at Rott_Inn helps reduce nutrient and pollutant loads, contributing to the ecological health of this transboundary river system.
