Overview
Oberes Trattnachtal wastewater treatment plant serves approximately 3,000 people in Niederndorf, Oberösterreich, Austria. It operates under the EU Urban Waste Water Treatment Directive.
The Oberes Trattnachtal wastewater treatment plant is located in Niederndorf, a locality in the municipality of Weibern, Bezirk Grieskirchen, Oberösterreich, Austria. The plant serves a population of approximately 2,996 people, making it a small agglomeration under EU classification. As a small-scale facility in Austria, the plant is subject to the EU Urban Waste Water Treatment Directive (91/271/EEC), which requires appropriate treatment for discharges into inland waters. For agglomerations of this size, secondary treatment is typically mandated unless the receiving waters are designated as sensitive areas, which may require more advanced treatment. The plant's treated effluent is discharged into the local watershed, which ultimately drains into the Danube River basin. The Danube is a major European waterway that flows into the Black Sea, supporting diverse aquatic ecosystems and providing water for millions of people. Proper treatment at this plant helps protect downstream water quality and ecological health.
Environmental context
The plant discharges into the Trattnach River, a tributary of the Inn River, which flows into the Danube. The Danube River basin is one of Europe's most important ecological corridors, supporting diverse fish species and migratory birds. The watershed is influenced by agricultural runoff and small settlements, making effective wastewater treatment crucial for maintaining water quality and preventing eutrophication in downstream lakes and the Black Sea.
