Overview
Aschachtal wastewater treatment plant serves St. Agatha, Oberösterreich, Austria, with a population equivalent of 18,573. It operates under the EU Urban Waste Water Treatment Directive.
The Aschachtal wastewater treatment plant is located in St. Agatha, a municipality in the Bezirk Grieskirchen district of Oberösterreich, Austria. The plant serves a population equivalent of 18,573, classifying it as a medium-sized agglomeration under EU regulations. As an Austrian facility, the plant is subject to the EU Urban Waste Water Treatment Directive (91/271/EEC), which requires secondary treatment for agglomerations of this size. The directive also mandates more stringent treatment if the receiving waters are designated as sensitive areas, which is common in the Danube basin. The treated effluent from Aschachtal is discharged into local watercourses that ultimately drain into the Danube River basin. The Danube is a major European river that flows into the Black Sea, supporting diverse aquatic ecosystems and providing water for agriculture and industry. The plant plays a key role in protecting these downstream environments from nutrient pollution.
Environmental context
The Aschachtal plant discharges into the Danube River basin, which flows through Central and Eastern Europe before reaching the Black Sea. The Danube supports a wide range of aquatic life, including migratory fish species such as sturgeon. Nutrient loading from wastewater can contribute to eutrophication in the Black Sea, making effective treatment critical for regional water quality.
