ARA GAV Maignerbach 1260 HO - Advanced Wastewater Treatment Plant in Meiseldorf, Austria

ARA GAV Maignerbach 1260 HO is a wastewater treatment facility located in Meiseldorf, a municipality in the Bezirk Horn district of Niederösterreich, Austria. The plant serves a population equivalent of 1,265 and operates with advanced treatment technology, ensuring high-quality effluent standards. As an advanced treatment plant, it goes beyond secondary treatment to remove nutrients such as nitrogen and phosphorus, which is typical for facilities in sensitive catchment areas. The plant has a designed capacity of 6,000 m³/day and currently discharges 742.14 m³/day of treated wastewater. Under the EU Urban Waste Water Treatment Directive (91/271/EEC), plants serving agglomerations of this size are required to provide appropriate treatment, and Austria's implementation ensures compliance with stringent effluent standards. The treated effluent is discharged into local watercourses that eventually drain into the Danube River basin, which flows into the Black Sea. The plant plays a crucial role in protecting the ecological health of the region's streams and rivers, supporting biodiversity and water quality in the downstream environment.

The plant discharges into local streams that are part of the Danube River basin, ultimately flowing into the Black Sea. The region's water bodies support diverse aquatic life and are important for local agriculture and recreation. Advanced treatment helps minimize nutrient loading, protecting downstream ecosystems from eutrophication and maintaining water quality standards.
