ARA Atzenbrugg 1379 TU - Advanced Wastewater Treatment in Moosbierbaum, Austria

ARA Atzenbrugg 1379 TU is a municipal wastewater treatment plant located in Moosbierbaum, a locality in the municipality of Atzenbrugg, Bezirk Tulln, Niederösterreich, Austria. The plant serves a population of 1,650 and has a design capacity of 3,500 m³/day, with an average discharge volume of 52.06 m³/day. The plant employs advanced treatment processes, which go beyond secondary treatment to remove nutrients and other pollutants. As an Austrian facility, it operates under the EU Urban Waste Water Treatment Directive (91/271/EEC), which requires advanced treatment for sensitive areas. For a plant of this scale, secondary treatment is mandatory, and advanced treatment may be required if the receiving water body is sensitive to eutrophication. The treated effluent is discharged into local watercourses that ultimately drain into the Danube River basin. The plant plays a key role in protecting the local aquatic environment and downstream ecosystems, including the Danube, which is a major European waterway supporting diverse aquatic life and human uses.

The plant discharges into the local tributaries of the Danube River, which flows through the Tulln Basin and eventually into the Black Sea. The receiving waters support diverse aquatic life and are part of a larger ecological network. Advanced treatment helps minimize nutrient loading, protecting downstream water quality and preventing eutrophication in sensitive areas.
