Overview
Dolsach wastewater treatment plant serves Lavant, Tirol, Austria, handling a population equivalent of 46,061. The plant operates under the EU Urban Waste Water Treatment Directive, ensuring compliance with secondary treatment standards for medium-siz
The Dolsach wastewater treatment plant is located in Lavant, a municipality in the district of Lienz, Tirol, Austria. It serves a population equivalent of 46,061, classifying it as a medium-sized agglomeration under EU regulations. The plant is situated in the Alpine region of East Tyrol, near the Drava River valley. As an Austrian facility, the plant operates under the EU Urban Waste Water Treatment Directive (91/271/EEC), which mandates secondary treatment for agglomerations between 10,000 and 150,000 population equivalent. For sensitive areas, more stringent treatment may be required. The regulatory framework ensures appropriate treatment levels. The treated effluent is discharged into the Drava River basin, which flows through Austria, Slovenia, Croatia, and Hungary before joining the Danube. The Drava River supports diverse aquatic life and is an important ecological corridor in the region. The plant plays a key role in protecting water quality in this transboundary river system.
Environmental context
The Dolsach plant discharges into the Drava River, a major tributary of the Danube. The Drava flows through the Alpine foothills and into the Pannonian Basin, supporting diverse aquatic habitats and migratory fish species. Downstream, the river passes through several ecologically sensitive areas, including riparian forests and wetlands that provide critical ecosystem services. The plant's operations help maintain water quality in this transboundary river system, which ultimately drains into the Black Sea.
