ARA Hohenberg 1664 LF is a municipal wastewater treatment plant located in Innerfahrafeld, a village in the municipality of Hohenberg, Bezirk Lilienfeld, Lower Austria. The plant serves a population of 639, placing it in the small agglomeration category under Austrian and EU regulations. 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 freshwater. For agglomerations under 2,000 population equivalent, the directive mandates secondary treatment or equivalent, ensuring that effluent meets quality standards before release. The plant's treated effluent likely discharges into a local stream or river within the Danube basin, as the region drains toward the Danube River via the Traisen or other tributaries. This contributes to the protection of downstream water quality in the Danube and ultimately the Black Sea, supporting aquatic ecosystems and biodiversity.
Environmental context
The plant is situated in the foothills of the Austrian Alps, within the catchment of the Danube River basin. Treated wastewater from the facility likely flows into a small tributary of the Traisen River, which joins the Danube near Krems. The Danube is a major European waterway supporting diverse aquatic life, including fish species such as sturgeon and salmon, and provides drinking water for millions. The plant's operations help maintain water quality in this ecologically sensitive river system.
