ARA Abwasserreinigung im Waldviertel GmbH 1558 WT Waidhofen_Th - Waidhofen an der Thaya Wastewater Treatment Plant

ARA Abwasserreinigung im Waldviertel GmbH 1558 WT Waidhofen_Th is a wastewater treatment plant located in Waidhofen an der Thaya, in the state of Niederösterreich, Austria. The plant serves a population of about 10,157 people, classifying it as a medium-sized agglomeration under Austrian and EU regulations. As a plant in Austria, it operates under the EU Urban Waste Water Treatment Directive (91/271/EEC), which requires secondary treatment for agglomerations of this size. The directive also mandates more advanced treatment if the receiving waters are sensitive to eutrophication. It is expected to meet these regulatory standards. The treated effluent is discharged into the local watershed, which ultimately drains into the Thaya River, a tributary of the Morava River, and then into the Danube River basin. This river system supports diverse aquatic life and is an important ecological corridor in Central Europe.

The plant discharges into the Thaya River, which flows into the Morava River and then the Danube River, eventually reaching the Black Sea. The Thaya River and its floodplains provide habitat for various fish species and migratory birds. The region is part of the Danube basin, a major European watershed that supports rich biodiversity and is subject to strict water quality standards under the EU Water Framework Directive.
