ARA Schrattenberg 2279 MI Wastewater Treatment Plant, Schrattenberg, Niederösterreich

ARA Schrattenberg 2279 MI is a wastewater treatment plant located in the municipality of Schrattenberg, in the district of Mistelbach, Niederösterreich, Austria. The plant serves a small population of 651 residents and is designed to handle a capacity of 4,000 cubic meters per day, with a current discharge volume of 414.10 cubic meters per day. The plant employs advanced treatment processes, which go beyond secondary treatment to remove nutrients and other pollutants. As an Austrian facility, it operates under the EU Urban Waste Water Treatment Directive (91/271/EEC), which requires appropriate treatment for agglomerations based on population equivalent and the sensitivity of receiving waters. The plant's treated effluent is discharged into local watercourses that eventually drain into the Danube River basin, contributing to the Black Sea watershed. The advanced treatment helps protect downstream aquatic ecosystems and supports water quality in the region.

The plant discharges into local streams that flow into the Danube River basin, ultimately reaching the Black Sea. The region's water bodies support diverse aquatic life and are part of a larger ecological network. Advanced treatment helps minimize nutrient loading, which is critical for preventing eutrophication in downstream waters.
