Overview
Helpfau Uttendorf is an advanced wastewater treatment plant in Helpfau-Uttendorf, Oberösterreich, Austria, serving 4,830 people with a designed capacity of 4,000 m³/day.
Helpfau Uttendorf is a wastewater treatment plant located in Helpfau-Uttendorf, a municipality in the Braunau district of Oberösterreich, Austria. The plant serves a population of 4,830 and has a designed capacity of 4,000 m³/day, with an average discharge volume of 618.44 m³/day. It provides advanced treatment, ensuring high-quality effluent before discharge. As an Austrian plant, Helpfau Uttendorf operates under the EU Urban Waste Water Treatment Directive 91/271/EEC, which requires advanced treatment for sensitive areas. For agglomerations of this size (under 10,000 PE), secondary treatment is the baseline, but the plant exceeds this with advanced treatment, likely due to local environmental sensitivity or regulatory requirements. The treated effluent is discharged into a local watercourse that eventually drains into the Inn River, a major tributary of the Danube. The Danube flows into the Black Sea, making this plant part of a large international river basin. The advanced treatment helps protect downstream aquatic ecosystems and supports water quality in the Danube catchment.
Environmental context
The plant discharges into a local stream that flows into the Inn River, which joins the Danube near Passau. The Danube is a major European waterway that ultimately reaches the Black Sea. The Inn River supports diverse aquatic life, including fish species like grayling and brown trout, and the advanced treatment at Helpfau Uttendorf helps maintain water quality in this ecologically sensitive river system.
