ARA GAV Wagram West 1140 TU is a municipal wastewater treatment plant located in Sankt Johann, within the Grafenwörth municipality in Niederösterreich, Austria. The facility serves a population of approximately 11,668, placing it in the medium agglomeration category under EU classification. As an Austrian plant, 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 designated as sensitive areas. The regulatory framework ensures compliance with European standards. The treated effluent is discharged into local watercourses that ultimately drain into the Danube River basin, a major European waterway flowing into the Black Sea. The plant plays a key role in protecting the region's water quality and supporting the ecological health of the Danube watershed.
Environmental context
