ARA Haringsee 3692 GF - Advanced Wastewater Treatment in Haringsee, Austria

ARA Haringsee 3692 GF is an advanced wastewater treatment plant located in Haringsee, a municipality in the Bezirk Gänserndorf district of Niederösterreich, Austria. The plant serves a small population of 774 people and has a designed capacity of 2000 m³/day, with a current discharge volume of 230.75 m³/day. As an advanced treatment facility, the plant goes beyond secondary treatment to remove nutrients and other pollutants, ensuring high-quality effluent. Under the EU Urban Waste Water Treatment Directive (91/271/EEC), Austria requires advanced treatment for sensitive areas, and this plant likely meets those standards despite its small scale. The plant's treated effluent is discharged into local water bodies that ultimately drain into the Danube River basin, which flows into the Black Sea. The plant plays a key role in protecting the region's water quality and supporting downstream ecosystems.

The plant discharges into the Danube River basin, which flows through Central and Eastern Europe before reaching the Black Sea. This watershed supports diverse aquatic life and is an important migratory corridor for fish species. The advanced treatment helps reduce nutrient loading, protecting downstream water quality and preventing eutrophication in the Black Sea.
