Overview
Walgau wastewater treatment plant serves Satteins in Vorarlberg, Austria, with a population equivalent of 25,826. It operates under the EU Urban Waste Water Treatment Directive, which mandates secondary treatment for agglomerations of this size.
The Walgau wastewater treatment plant is located in Satteins, a municipality in the Bezirk Feldkirch district of Vorarlberg, Austria. It serves a population equivalent of 25,826, classifying it as a medium-sized agglomeration under EU regulations. The plant is situated near the Rheintal/Walgau Autobahn, reflecting its role in the region's wastewater infrastructure. As an Austrian facility, the plant operates under the EU Urban Waste Water Treatment Directive (91/271/EEC), which requires secondary treatment for agglomerations with a population equivalent between 10,000 and 150,000. The designed capacity is 1.00 (likely in thousand cubic meters per day or similar units), indicating the plant's scale. The regulatory framework ensures compliance with discharge standards. The plant's treated effluent is discharged into the local watershed, which ultimately drains into the Rhine River via the Alpine Rhine. The Rhine is a major European waterway that flows through Switzerland, Germany, and the Netherlands before reaching the North Sea. The Vorarlberg region is ecologically sensitive, with the Rhine supporting diverse aquatic life and serving as an important migratory corridor for fish species.
Environmental context
The Walgau plant discharges into the Alpine Rhine, a headwater section of the Rhine River that flows through the Alps and eventually reaches the North Sea. The Rhine basin supports diverse aquatic ecosystems, including salmonid populations and riparian habitats. The plant's location in the Vorarlberg region, near the border with Switzerland and Liechtenstein, places it in a sensitive alpine watershed where nutrient loading must be carefully managed to protect downstream water quality.
Frequently asked questions
The Walgau wastewater treatment plant is located in Satteins, in the Bezirk Feldkirch district of Vorarlberg, Austria, near the Rheintal/Walgau Autobahn.
The plant serves a population equivalent of 25,826, classifying it as a medium-sized agglomeration under EU regulations.
The treated effluent from the Walgau plant is discharged into the local watershed, which flows into the Alpine Rhine, a major tributary of the Rhine River.
As an Austrian facility, the Walgau plant operates under the EU Urban Waste Water Treatment Directive (91/271/EEC), which requires secondary treatment for agglomerations of its size.
Under the EU UWWTD, plants serving between 10,000 and 150,000 population equivalent must provide secondary treatment, with tertiary treatment required if discharging into sensitive areas. Austrian plants typically meet these standards through biological treatment processes.
