Bad Birnbach Wastewater Treatment Plant: Serving 13,193 People in Bavaria, Germany

The Bad Birnbach wastewater treatment plant is located in the town of Bad Birnbach, in the Landkreis Rottal-Inn district of Bavaria, Germany. It serves a population of around 13,193 residents, classifying it as a medium-sized agglomeration under EU regulations. The plant is part of the municipal infrastructure managed by the local authority. 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 with a population equivalent (PE) between 10,000 and 150,000. For plants of this size, the directive also mandates appropriate treatment before discharge into sensitive areas, which are common in Bavaria's river systems. The treated effluent from the plant is discharged into local watercourses that eventually drain into the Danube River basin. The Danube is a major European river that flows into the Black Sea, supporting diverse aquatic ecosystems along its course. The plant's operations help protect the water quality of these downstream environments.

The plant discharges into local streams that are part of the Danube River basin, which flows through Central and Eastern Europe before reaching the Black Sea. The Danube supports a wide range of aquatic life, including fish species such as sturgeon and migratory birds. The region's watershed is ecologically sensitive, and the plant's treatment processes help maintain water quality standards in this important river system.
