Overview
Trofaiach wastewater treatment plant serves the city of Trofaiach in Styria, Austria. It handles a population equivalent of approximately 17,084 and operates under EU Urban Waste Water Treatment Directive standards.
The Trofaiach wastewater treatment plant is located in the city of Trofaiach, in the state of Styria, Austria. It serves a population of about 17,084, placing it in the medium agglomeration category under EU classification. The plant is situated inland, away from coastal areas, and its operations are part of Austria's municipal wastewater infrastructure. As a plant serving a medium-sized agglomeration, it is expected to comply with the EU Urban Waste Water Treatment Directive (91/271/EEC), which requires secondary treatment for such populations. The directive also mandates more advanced treatment if the receiving waters are sensitive to eutrophication. The plant's treatment processes are designed to meet these regulatory standards, ensuring effective removal of organic matter and nutrients. The treated effluent from the plant is discharged into local watercourses that eventually drain into the Danube River basin. The Danube is a major European river that flows into the Black Sea, making the plant's performance important for downstream water quality. The surrounding region is characterized by alpine terrain and supports diverse aquatic ecosystems, which benefit from proper wastewater treatment.
Environmental context
The plant discharges into local streams that are part of the Danube River basin, ultimately flowing into the Black Sea. The receiving waters support diverse aquatic life, including fish species such as brown trout and grayling, which are sensitive to pollution. Proper treatment helps maintain the ecological health of these alpine streams and the downstream Danube ecosystem.
