Vockla Redl Wastewater Treatment Plant, Gampern, Oberösterreich

Vockla Redl is a wastewater treatment plant located in Zeiling, Gampern, in the Bezirk Vöcklabruck district of Oberösterreich, Austria. It serves a population equivalent of 46,082, classifying it as a medium-sized agglomeration under EU classification. The plant is situated in a region characterized by rolling hills and agricultural landscapes, typical of the Salzkammergut area. As an Austrian plant, Vockla Redl operates under the EU Urban Waste Water Treatment Directive (91/271/EEC), which requires secondary treatment for agglomerations between 10,000 and 150,000 population equivalent. For larger agglomerations or discharges into sensitive areas, tertiary treatment may be required. The regulatory framework ensures compliance with national and EU standards. The treated effluent from Vockla Redl is discharged into local watercourses that ultimately drain into the Danube River basin. The Danube flows eastward through Austria and several other countries before reaching the Black Sea. The plant's operations contribute to protecting the water quality of the Danube watershed, which supports diverse aquatic life and serves as a vital ecological corridor in Central Europe.

Vockla Redl discharges into local streams that are part of the Danube River basin. The Danube is the second-longest river in Europe, flowing through ten countries and draining into the Black Sea. The watershed supports a rich diversity of fish species and provides critical habitat for migratory birds. The plant's location in a rural area means its effluent can affect small receiving waters, making proper treatment essential for maintaining ecological balance and preventing eutrophication.
