ARA Hausbrunn 2034 MI - Advanced Wastewater Treatment in Hausbrunn, Niederösterreich

ARA Hausbrunn 2034 MI is a wastewater treatment facility located in the small town of Hausbrunn, in the Bezirk Mistelbach district of Niederösterreich, Austria. The plant serves a population of approximately 960 residents, reflecting its role in managing domestic wastewater for a rural community. It operates with advanced treatment technology, ensuring high-quality effluent standards. As an advanced treatment plant, ARA Hausbrunn 2034 MI is designed to meet stringent Austrian and EU regulatory requirements under the EU Urban Waste Water Treatment Directive (91/271/EEC). The plant has a designed capacity of 1,500 m³/day and currently treats an average discharge volume of 625.31 m³/day, indicating it operates well below its maximum capacity. This spare capacity allows for future population growth or seasonal variations. The treated effluent from the plant is discharged into local watercourses that ultimately drain into the Danube River basin, a major European watershed. The advanced treatment level helps protect downstream aquatic ecosystems, including the Danube's diverse fish populations and riparian habitats. The plant's inland location, far from the coast, reduces direct marine impact.

The plant discharges into small streams that flow into the Thaya River, a tributary of the Morava River, which joins the Danube near Bratislava. The Danube River basin is ecologically significant, supporting diverse aquatic life and serving as a major migratory corridor for fish species. The advanced treatment ensures minimal nutrient and pollutant loading, protecting the sensitive floodplain ecosystems along the lower Thaya and Morava rivers.
