Overview
Eberschwang wastewater treatment plant serves approximately 4,800 residents in Oberösterreich, Austria. The facility discharges into the Antiesen river, part of the Inn-Danube basin.
The Eberschwang wastewater treatment plant is located in the municipality of Eberschwang in Oberösterreich, Austria. It serves a population of about 4,800 people, classifying it as a small agglomeration under Austrian and EU regulations. As an Austrian plant serving fewer than 10,000 people, it operates under the EU Urban Waste Water Treatment Directive 91/271/EEC, which requires appropriate treatment for discharges into freshwater. For small agglomerations, secondary treatment is typically mandated to protect receiving water quality. The plant discharges treated effluent into the Antiesen river, a tributary of the Inn River, which flows into the Danube. The Danube ultimately drains into the Black Sea. The Antiesen supports local aquatic life and contributes to the ecological health of the Inn-Danube system.
Environmental context
The Antiesen river flows through the Innviertel region before joining the Inn River, a major Danube tributary. The Inn-Danube corridor is an important migratory route for fish species such as Danube salmon and barbel. The plant's discharge must meet Austrian water quality standards to protect downstream ecosystems, including sensitive floodplain habitats along the Danube.

Under the EU Urban Waste Water Treatment Directive (91/271/EEC), agglomerations with a population equivalent (PE) between 2,000 and 10,000 are required to have appropriate treatment, typically secondary treatment, to protect receiving waters.
For small agglomerations like Eberschwang (under 10,000 PE), Austrian regulations mandate secondary treatment or equivalent, ensuring removal of organic matter and suspended solids before discharge into freshwater bodies.
