ARA Weikendorf 3723 GF - Advanced Wastewater Treatment in Stripfing, Austria

ARA Weikendorf 3723 GF is an advanced wastewater treatment plant located in Stripfing, a locality in the municipality of Weikendorf, Bezirk Gänserndorf, Niederösterreich, Austria. The plant serves a population equivalent of 1,920 and has a designed capacity of 3,000 m³/day, with an average discharge volume of 491.73 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 (serving fewer than 10,000 people), secondary treatment is typically mandated, but the advanced level indicates a higher environmental standard. The treated effluent is discharged into local watercourses that drain into the Danube River basin, ultimately reaching the Black Sea. The plant plays a key role in protecting the region's groundwater and surface water quality, supporting the ecological health of the Marchfeld area and downstream aquatic habitats.

The plant discharges into the local drainage network within the Danube River basin, which flows into the Black Sea. The region's aquatic ecosystems support diverse species, including fish and macroinvertebrates, and the advanced treatment helps reduce nutrient loading that could otherwise contribute to eutrophication in downstream waters.
