ARA GV Horn fur Abwasserbeseitigung 1234 HO - Horn, Austria Wastewater Treatment Plant

ARA GV Horn fur Abwasserbeseitigung 1234 HO is a municipal wastewater treatment plant located in Horn, Niederösterreich, Austria. Serving a population of approximately 19,376, the plant is part of the region's infrastructure for managing domestic wastewater. Horn lies in the Waldviertel region, a rural area with a mix of agricultural and small-scale industrial activity. As an Austrian facility, the plant operates under the EU Urban Waste Water Treatment Directive (91/271/EEC), which requires secondary treatment for agglomerations with a population equivalent (PE) between 10,000 and 150,000. For this scale, the directive also mandates appropriate nutrient removal in sensitive areas. The plant's design and operation align with these regulatory standards to ensure effective treatment before discharge. The treated effluent from the plant is discharged into local watercourses that eventually drain into the Danube River basin. The Danube is a major European waterway, flowing into the Black Sea. The plant's operations help protect downstream aquatic ecosystems, including the Danube's diverse fish populations and riparian habitats, by reducing nutrient and pollutant loads.

The plant discharges into local streams that are part of the Danube River basin, which flows through Central and Eastern Europe before reaching the Black Sea. The downstream environment includes ecologically sensitive areas that support diverse aquatic life, including migratory fish species. Effective wastewater treatment is crucial to prevent eutrophication and maintain water quality in the Danube and its tributaries.
