The plant serves a population of approximately 106,504, classifying it as a large agglomeration under EU regulations. It is situated inland, away from coastal areas, and treats wastewater from the urban area of Wiener Neustadt. As a large agglomeration in Austria, the plant is subject to the EU Urban Waste Water Treatment Directive (91/271/EEC), which requires secondary treatment as a minimum and tertiary treatment in sensitive areas. The plant's treatment processes are designed to meet these standards, ensuring compliance with national and EU regulations. The facility is part of Austria's comprehensive wastewater infrastructure, which emphasizes high treatment standards to protect water quality. The treated effluent from the plant is discharged into local water bodies that ultimately flow into the Danube River basin. The Danube is a major European river that drains into the Black Sea, supporting diverse aquatic ecosystems. The plant plays a crucial role in protecting downstream water quality and the ecological health of the Danube watershed.

The plant discharges into the local water network that feeds into the Danube River basin, which flows through Central and Eastern Europe before reaching the Black Sea. The Danube supports a rich diversity of fish and bird species, and its delta is an ecologically sensitive area. The plant's treatment helps reduce nutrient and pollutant loads, safeguarding aquatic habitats and water quality in the downstream environment.
