ARA Ganserndorf 320 GF Wastewater Treatment Plant, Gänserndorf, Austria

ARA Ganserndorf 320 GF is a municipal wastewater treatment plant located in Gänserndorf, a town in the Niederösterreich region of Austria. The plant serves a population of 633, classifying it as a small agglomeration under EU regulations. As a small-scale facility in Austria, the plant is subject to the EU Urban Waste Water Treatment Directive (91/271/EEC), which requires appropriate treatment for agglomerations of this size. Austrian plants typically employ mechanical-biological treatment to meet national and EU standards. The plant discharges treated effluent into local waterways that ultimately drain into the Danube River basin. The Danube is a major European river that flows into the Black Sea, supporting diverse aquatic ecosystems and serving as a critical water resource for the region.

The plant's treated effluent enters local streams that feed into the Danube River basin, a vast watershed spanning multiple countries. The Danube supports rich biodiversity, including fish species like sturgeon and migratory birds. Downstream, the river flows into the Black Sea, a semi-enclosed sea with sensitive ecological conditions. Protecting water quality in this basin is essential for maintaining aquatic habitats and human uses such as drinking water and recreation.
