ARA Moosbrunn 351 WU Wastewater Treatment Plant, Moosbrunn, Niederösterreich

ARA Moosbrunn 351 WU is a wastewater treatment facility located in Moosbrunn, a municipality in the district of Bruck an der Leitha in Niederösterreich, Austria. The plant serves a population of about 2,969 and has a designed capacity of 3,000 m³ per day, with a current discharge volume of 614.5 m³ per 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 appropriate treatment for agglomerations of this size. The plant's advanced treatment level aligns with the directive's standards for sensitive areas. The treated effluent is discharged into local water bodies 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. The plant's advanced treatment helps protect the downstream environment from nutrient pollution and other contaminants.

The plant discharges into local streams that are part of the Danube River basin. The Danube flows through multiple countries before reaching the Black Sea, supporting a wide range of aquatic life and providing important ecosystem services. Advanced treatment at this plant reduces nutrient loads, helping to prevent eutrophication in downstream waters and protect the ecological health of the Danube and the Black Sea.
