Overview
Tacherting wastewater treatment plant in Bavaria, Germany, serves about 7,000 people with advanced treatment. It has a designed capacity of 9,000 m³/day and discharges 765 m³/day of treated effluent.
Tacherting wastewater treatment plant is located in the municipality of Tacherting in the Traunstein district of Bavaria, Germany. The plant serves a population of approximately 7,000 residents, making it a small to medium-sized facility under the EU Urban Waste Water Treatment Directive (UWWTD). It is situated inland, away from coastal areas, and treats domestic 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 9,000 m³/day and an average discharge volume of 765 m³/day, the facility operates well below its capacity, indicating room for future growth or seasonal variations. The plant 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 ultimately drain into the Danube River basin, contributing to the Black Sea watershed. The plant plays a key role in protecting the region's freshwater resources and downstream ecosystems, including the Danube Delta, by ensuring high-quality effluent before release.
Environmental context
The plant discharges into local streams that feed into the Alz River, a tributary of the Inn River, which flows into the Danube. The Danube eventually reaches the Black Sea, making this plant part of a vast transboundary watershed. The region supports diverse aquatic life, including fish species such as Danube salmon and various migratory birds. Advanced treatment helps minimize nutrient loading and protects downstream water quality.
Frequently asked questions
The plant is located in Tacherting, in the Traunstein district of Bavaria, Germany, at Hacknerweg 30.
The plant serves approximately 6,962 people, classifying it as a small to medium agglomeration under EU regulations.
The plant discharges treated effluent into local water bodies that flow into the Alz River, part of the Danube basin, ultimately reaching the Black Sea.
The plant provides advanced treatment, which exceeds the secondary treatment standard required by the EU Urban Waste Water Treatment Directive for agglomerations of this size.
Under the EU UWWTD, agglomerations with a population equivalent (PE) between 2,000 and 10,000 require secondary treatment. Tacherting, serving about 7,000 PE, meets this requirement and goes further with advanced treatment, likely due to sensitive receiving waters.
