Reichraming Wastewater Treatment Plant, Oberösterreich | Austria

The Reichraming wastewater treatment plant is located in the municipality of Reichraming, Bezirk Steyr-Land, in the state of Oberösterreich, Austria. It serves a population of approximately 1,589 residents, reflecting a small-scale municipal facility typical of rural alpine communities. The plant employs advanced treatment processes, which go beyond the secondary treatment standard required by the EU Urban Waste Water Treatment Directive (91/271/EEC) for agglomerations of this size. Its designed capacity of 4,200 m³/day indicates headroom for future growth or seasonal variations. The facility discharges an average of 244.92 m³/day of treated wastewater. The treated effluent is released into a local watercourse that drains into the Enns River, a major tributary of the Danube. The Danube ultimately flows into the Black Sea. The plant's advanced treatment helps protect the sensitive alpine aquatic ecosystems and downstream water quality in the Danube basin.

The plant discharges into a small stream that flows into the Enns River, which joins the Danube near Enns. The Danube then travels through Central and Eastern Europe to the Black Sea. The Enns River supports diverse aquatic life, including fish species such as grayling and brown trout. The advanced treatment at Reichraming reduces nutrient loads, protecting the river's ecological health and preventing eutrophication in downstream reservoirs.
