Pram Pfudabach Wastewater Treatment Plant, Windten, Oberösterreich

Pram Pfudabach is a wastewater treatment plant located in Windten, a locality in Taufkirchen an der Pram, Oberösterreich, Austria. The plant serves a population of approximately 4,158 people, placing it in the small agglomeration category under EU regulations. It is situated inland, away from coastal areas, and discharges into local watercourses. As a plant serving fewer than 10,000 population equivalents, it falls under the EU Urban Waste Water Treatment Directive (91/271/EEC) which requires appropriate treatment based on the sensitivity of the receiving waters. For small agglomerations in non-sensitive areas, secondary treatment is typically mandated. It operates within Austria's stringent national water quality framework, which implements EU directives. The plant's treated effluent likely discharges into the Pram River, a tributary of the Inn River, which flows into the Danube and ultimately the Black Sea. This river system supports diverse aquatic life and is important for regional biodiversity. The plant plays a key role in protecting water quality in the Inn-Danube basin.

The plant discharges into the Pram River, a tributary of the Inn River, which joins the Danube River near Passau. The Danube flows into the Black Sea, making this plant part of a vast transboundary watershed. The local watershed supports diverse aquatic ecosystems, including fish species such as grayling and brown trout. The region is characterized by agricultural land use, and the plant helps mitigate nutrient pollution that could otherwise impact downstream water quality.
