ARA Harmannsdorf 1435 KO is a municipal wastewater treatment plant located in Seebarn, a village in the Harmannsdorf municipality of Niederösterreich, Austria. The plant serves a population of 4,110 and has a designed capacity of 4,600 m³/day, with a reported discharge volume of 513.00 m³/day. The plant employs advanced treatment processes, which go beyond the secondary treatment required by the EU Urban Waste Water Treatment Directive (91/271/EEC) for agglomerations of this size. This level of treatment typically includes nutrient removal (nitrogen and phosphorus) to protect sensitive receiving waters. The treated effluent is discharged into local watercourses that ultimately drain into the Danube River basin, contributing to the Black Sea catchment. The plant's advanced treatment helps safeguard downstream aquatic ecosystems and supports water quality in the region.
Environmental context
The plant discharges into small streams in the Harmannsdorf area, which flow into the Danube River via the Kamp or similar tributaries. The Danube is a major European river that supports diverse aquatic life and provides drinking water for millions. The advanced treatment at this plant helps reduce nutrient loads, protecting the Danube's ecological health and preventing eutrophication in downstream waters, including the Black Sea.
