Overview
ARA Thaya PZ 1141 WT is an advanced wastewater treatment plant serving 1,325 people in Thaya, Niederösterreich, Austria. It discharges 454.39 m³/day of treated effluent into the local water system.
ARA Thaya PZ 1141 WT is a municipal wastewater treatment facility located in Thaya, a town in the Bezirk Waidhofen an der Thaya district of Niederösterreich, Austria. The plant serves a population of approximately 1,325, classifying it as a small agglomeration under Austrian and EU regulations. The plant employs advanced treatment processes, which go beyond the secondary treatment standard required by the EU Urban Waste Water Treatment Directive (91/271/EEC) for agglomerations of this size. With a designed capacity of 2,070 m³/day and an actual discharge volume of 454.39 m³/day, the facility operates well below its capacity, indicating room for future growth or seasonal variations. The treated effluent is discharged into the Thaya River, a tributary of the Dyje River, which flows into the Morava River and ultimately the Danube River basin. This connection to the Danube highlights the plant's role in protecting downstream ecosystems, including the Danube Delta, a region of high ecological importance.
Environmental context
The plant discharges into the Thaya River, which flows into the Dyje River, a major tributary of the Morava River. The Morava joins the Danube near Bratislava, making the plant part of the larger Danube basin. The downstream environment supports diverse aquatic life and is an important migratory corridor for fish species. Advanced treatment helps minimize nutrient loading, protecting water quality in the sensitive Danube ecosystem.
