Irschenberg Wastewater Treatment Plant: Advanced Treatment in Bavaria, Germany

The Irschenberg wastewater treatment plant is located in the municipality of Irschenberg in the district of Miesbach, Bavaria, Germany. It serves a population of approximately 2,823 people, classifying it as a small agglomeration under the EU Urban Waste Water Treatment Directive (UWWTD). The plant is situated inland, away from coastal areas, and treats wastewater from the local community. The plant employs advanced treatment processes, which go beyond the secondary treatment standard required by the EU UWWTD for agglomerations of this size. With a designed capacity of 5,000 m³/day and a current discharge volume of 406 m³/day, the plant operates well below its capacity, indicating room for future growth. The facility is part of Germany's robust wastewater infrastructure, which is regulated under national laws implementing EU directives. The treated effluent is discharged into local water bodies that eventually drain into the Inn River and then the Danube River, ultimately reaching the Black Sea. The plant plays a key role in protecting the water quality of the region's streams and rivers, which support diverse aquatic life and are used for recreation and agriculture downstream.

The plant discharges into small streams in the Mangfall River basin, which flows into the Inn River and then the Danube River, eventually reaching the Black Sea. The region is characterized by alpine foothills and agricultural land, making water quality protection important for downstream ecosystems and drinking water sources. The advanced treatment helps minimize nutrient loading and protects sensitive aquatic habitats.
