ARA Wildendurnbach 694 MI - Advanced Wastewater Treatment in Wildendürnbach, Austria

ARA Wildendurnbach 694 MI is a wastewater treatment facility located in the town of Wildendürnbach, in the Bezirk Mistelbach district of Niederösterreich, Austria. The plant serves a small population of 953 residents and is designed to handle up to 5000 cubic meters of wastewater per day, with an actual discharge volume of 722.13 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, the directive mandates at least secondary treatment, and the advanced level indicates compliance with stricter standards. The treated effluent is discharged into local water bodies, contributing to the protection of the Danube River basin, which ultimately drains into the Black Sea. The plant plays a key role in safeguarding water quality in the region, supporting aquatic life and downstream ecosystems.

The plant discharges into local streams that are part of the Thaya River system, a tributary of the Morava River, which flows into the Danube. The Danube then carries water to the Black Sea. The region's aquatic ecosystems support diverse species, including fish and invertebrates, and the plant's advanced treatment helps prevent eutrophication and maintain ecological balance in these waters.
