Ramsau Wastewater Treatment Plant, Ramsau am Dachstein, Styria, Austria

The Ramsau wastewater treatment plant is located in Ramsau am Dachstein, a municipality in the Styria region of Austria. Serving a population of 4,674, the plant is part of the local municipal wastewater infrastructure for this Alpine community. The plant employs advanced treatment processes, which go beyond the secondary treatment standard required by the EU Urban Waste Water Treatment Directive (91/271/EEC) for agglomerations of this size. With a designed capacity of 12,550 m³/day and an actual discharge volume of 752.29 m³/day, the facility has ample capacity to handle current loads. The treated effluent is discharged into the local watershed, which ultimately drains into the Enns River and then the Danube River basin. The plant's advanced treatment helps protect the sensitive Alpine aquatic environment, supporting downstream ecosystems and water quality in the Danube catchment.

The plant discharges into the Enns River catchment, a tributary of the Danube River. The Alpine watershed is ecologically sensitive, supporting diverse aquatic life and providing important habitat for cold-water species. The advanced treatment ensures minimal nutrient and pollutant loading, protecting downstream water bodies including the Danube Delta ecosystem.
