ZV Brannenburg Flintsbach Wastewater Treatment Plant, Flintsbach am Inn, Bavaria

ZV Brannenburg Flintsbach is a municipal wastewater treatment plant located in Flintsbach am Inn, a town in the Landkreis Rosenheim district of Bavaria, Germany. The plant serves a population of around 11,400 residents, placing it in the medium agglomeration category under European Union classification. Under the EU Urban Waste Water Treatment Directive (91/271/EEC), treatment plants serving agglomerations of this size are required to provide secondary treatment as a minimum. In sensitive areas, such as those draining into nutrient-sensitive water bodies, more stringent treatment may be mandated. It is expected to comply with German national standards implementing the directive. The treated effluent from the plant is discharged into the local water system, 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 transboundary river basin. The plant plays a key role in protecting the water quality of the Inn and downstream ecosystems.

The plant discharges into the Inn River, which flows into the Danube and eventually the Black Sea. This river system supports diverse aquatic life and is an important migratory corridor for fish species. The region is ecologically sensitive due to the Alpine foothills and the need to maintain water quality for downstream communities and habitats.
