Serving a population of 110,405, it is classified as a large agglomeration under EU standards. The plant is situated near the Austrian border, in the foothills of the Alps, and plays a key role in managing municipal wastewater for this historic city. As a large agglomeration, the plant is expected to meet the requirements of the EU Urban Waste Water Treatment Directive (91/271/EEC), which mandates secondary treatment as a minimum and tertiary treatment in sensitive areas. Its scale suggests it is designed to handle significant flows. The regulatory framework ensures that effluent quality meets standards to protect receiving waters. The plant's treated effluent likely discharges into local watercourses that drain into the Danube River basin, eventually reaching the Black Sea. The region is ecologically sensitive, with diverse aquatic life and important groundwater resources. Proper treatment at this plant helps protect downstream ecosystems and supports the environmental health of the Danube watershed.

The plant is located in the Danube River basin, with treated effluent likely flowing into local streams that feed the Rába River, a tributary of the Danube. The Danube ultimately discharges into the Black Sea. The region supports diverse aquatic habitats and is important for migratory fish species. Effective wastewater treatment is critical to prevent nutrient pollution and protect downstream water quality in this transboundary river system.
