ARA Rabensburg 2248 MI - Advanced Wastewater Treatment Plant in Rabensburg, Niederösterreich

ARA Rabensburg 2248 MI is an advanced wastewater treatment facility located in Rabensburg, a municipality in the Bezirk Mistelbach district of Niederösterreich, Austria. The plant serves a population equivalent of 1,478 and is designed to handle up to 2,000 m³ of wastewater per day, with an average daily discharge of 263.76 m³. As an advanced treatment plant, ARA Rabensburg 2248 MI goes beyond secondary treatment to remove nutrients such as nitrogen and phosphorus, ensuring high-quality effluent. This level of treatment is typical for plants in Austria, which operates under the EU Urban Waste Water Treatment Directive (91/271/EEC). For small agglomerations like Rabensburg (under 2,000 PE), the directive requires appropriate treatment, and Austria's national regulations often mandate advanced treatment to protect sensitive water bodies. The treated wastewater from the plant is discharged into local watercourses that eventually drain into the Danube River basin, a major European watershed. The Danube flows through multiple countries before reaching the Black Sea, making the protection of its tributaries critical for downstream ecosystems. The plant's advanced treatment helps reduce nutrient loads that could contribute to eutrophication in the Danube and the Black Sea.

The plant discharges into local streams that are part of the Danube River basin, which ultimately flows into the Black Sea. This watershed supports diverse aquatic life and is an important migratory corridor for fish species. The advanced treatment at ARA Rabensburg 2248 MI helps minimize nutrient pollution, protecting downstream water quality in the Danube and its delta.
