ARA Gross Gerungs 4179 zT - Advanced Wastewater Treatment Plant in Niederösterreich, Austria

ARA Gross Gerungs 4179 zT is a municipal wastewater treatment facility located in Groß Gerungs, a town in the Zwettl district of Lower Austria (Niederösterreich). The plant serves a population of 1,575 and is part of Austria's comprehensive wastewater infrastructure, which is regulated under the EU Urban Waste Water Treatment Directive (91/271/EEC). As a small agglomeration, it meets the directive's requirements for appropriate treatment before discharge. The plant employs advanced treatment processes, ensuring a high level of pollutant removal. It has a designed capacity of 4,800 m³/day and currently discharges an average of 614.35 m³/day of treated wastewater. This indicates that the plant operates well below its capacity, with room for future growth or seasonal variations. The treated effluent is discharged into local watercourses that eventually drain into the Danube River basin. The plant plays a crucial role in protecting the region's water quality, supporting aquatic life in downstream ecosystems. Its advanced treatment helps minimize nutrient loading and other pollutants, contributing to the ecological health of the Danube catchment area.

The plant discharges into small streams that flow into the Kamp River, a tributary of the Danube. The Danube River basin is a major European watershed supporting diverse aquatic habitats and migratory fish species. The advanced treatment at this plant helps reduce nutrient and pollutant loads, protecting downstream ecosystems including the Danube Delta, a region of high ecological value.
