Overview
ARA Wasser und Abwasserverb Munchendorf 1359 MD is an advanced wastewater treatment plant in Münchendorf, Niederösterreich, Austria, serving approximately 2,729 people with a designed capacity of 3,100 m³/day.
ARA Wasser und Abwasserverb Munchendorf 1359 MD is an advanced wastewater treatment facility located in Münchendorf, a municipality in the Mödling district of Niederösterreich, Austria. The plant serves a population of approximately 2,729 and has a designed capacity of 3,100 cubic meters per day, with an average discharge volume of 846.20 cubic meters per day. As an advanced treatment plant, it goes beyond secondary treatment to remove nutrients such as nitrogen and phosphorus, which is typical for facilities in sensitive catchment areas under the EU Urban Waste Water Treatment Directive (91/271/EEC). This directive requires advanced treatment for agglomerations of this size when discharging into sensitive areas, ensuring high effluent quality. The treated wastewater is discharged into local watercourses that ultimately drain into the Danube River basin, which flows into the Black Sea. The plant plays a key role in protecting the ecological health of the surrounding watershed, supporting aquatic life and downstream water quality in the Danube ecosystem.
Environmental context
The plant discharges into local streams that are part of the Danube River basin, which flows through Central and Eastern Europe before reaching the Black Sea. The Danube supports diverse aquatic ecosystems and is a critical migratory corridor for fish species. Advanced treatment at this plant helps reduce nutrient loading, mitigating eutrophication risks in downstream waters and protecting biodiversity in the watershed.
