Ried _Traunkreis Wastewater Treatment Plant, Ried im Traunkreis, Austria

The Ried _Traunkreis wastewater treatment plant is located in Ried im Traunkreis, a municipality in the Bezirk Kirchdorf district of Oberösterreich, Austria. It serves a population of approximately 2,002 people, classifying it as a small agglomeration under Austrian and EU regulations. The plant employs advanced treatment processes, which go beyond the secondary treatment required by the EU Urban Waste Water Treatment Directive (91/271/EEC) for agglomerations of this size. With a designed capacity of 4,000 m³/day and an average daily discharge of 763.01 m³/day, the plant operates well within its capacity, ensuring effective treatment of municipal wastewater. The treated effluent is discharged into local water bodies that eventually drain into the Danube River basin, contributing to the overall water quality of the region. The plant's advanced treatment helps protect downstream ecosystems, including the Danube and its tributaries, which support diverse aquatic life and are important for regional biodiversity.

The plant discharges into local streams that are part of the Danube River basin, ultimately flowing into the Black Sea. The region's watershed supports sensitive aquatic habitats, and the advanced treatment helps minimize nutrient and pollutant loads, protecting downstream water quality and ecological health.
