ARA Ferschnitz 3053 AM - Advanced Wastewater Treatment Plant in Ferschnitz, Austria

ARA Ferschnitz 3053 AM is a wastewater treatment plant located in Ferschnitz, a municipality in the Bezirk Amstetten district of Niederösterreich, Austria. The plant serves a population of 1,587 and is classified as a small agglomeration under the EU Urban Waste Water Treatment Directive (91/271/EEC). The plant employs advanced treatment processes, which go beyond secondary treatment to remove nutrients such as nitrogen and phosphorus. With a designed capacity of 2,000 m³/day and an average discharge volume of 349.04 m³/day, the plant operates well within its capacity, ensuring effective treatment of municipal wastewater. The treated effluent is discharged into local watercourses that eventually drain into the Danube River basin. The plant's advanced treatment helps protect downstream aquatic ecosystems, including the Danube, which supports diverse fish populations and serves as a critical migratory corridor for species such as sturgeon. The region's water quality is regulated under Austrian and EU frameworks to maintain ecological health.

The plant discharges treated wastewater into small streams in the Ybbs River catchment, a tributary of the Danube. The Danube River basin is a major European waterway supporting diverse aquatic life, including fish species like the Danube salmon and migratory sturgeon. Advanced treatment at this plant helps reduce nutrient loading, protecting downstream ecosystems from eutrophication and maintaining water quality for drinking water and recreation.
