ARA Wilfersdorf 2330 MI - Advanced Wastewater Treatment in Ebersdorf an der Zaya, Lower Austria

ARA Wilfersdorf 2330 MI is a municipal wastewater treatment plant located in Ebersdorf an der Zaya, a village in the district of Mistelbach, Lower Austria. The plant serves a population of 1,590 and is part of the region's water infrastructure, operating under Austrian and EU regulations. The plant provides advanced treatment, which goes beyond the secondary treatment required by the EU Urban Waste Water Treatment Directive for agglomerations of this size. With a designed capacity of 4,000 m³/day and a current discharge volume of 659.38 m³/day, the facility has ample capacity for future growth. Advanced treatment typically includes nutrient removal to protect sensitive water bodies. The treated effluent is discharged into local waterways that drain into the Zaya River, a tributary of the Morava River, which eventually flows into the Danube. The Danube then carries the water to the Black Sea. The plant plays a key role in protecting the local aquatic ecosystem and downstream water quality in the Danube basin.

The plant's discharge enters the Zaya River, a small river in the Weinviertel region of Lower Austria. The Zaya flows into the Morava River, which forms part of the border between Austria and Slovakia before joining the Danube. The Danube is a major European river that drains into the Black Sea. The surrounding area is agricultural, and the plant's advanced treatment helps reduce nutrient loads that could cause eutrophication in downstream waters, including the ecologically sensitive Danube Delta.
