ARA Engelhartstetten 1340 GF - Advanced Wastewater Treatment in Engelhartstetten, Austria

ARA Engelhartstetten 1340 GF is an advanced wastewater treatment plant located in Engelhartstetten, a municipality in the Bezirk Gänserndorf of Niederösterreich, Austria. The plant serves a population of approximately 1,028 residents and is designed with a capacity of 2,700 m³ per day, with a current discharge volume of 456.60 m³/day. As an advanced treatment facility, it goes beyond secondary treatment to remove nutrients such as nitrogen and phosphorus, ensuring high-quality effluent. The plant operates under the EU Urban Waste Water Treatment Directive 91/271/EEC, which requires advanced treatment for sensitive areas. For a small agglomeration of this size, the directive mandates appropriate collection and treatment systems. The treated effluent is discharged into the local water environment, contributing to the protection of the Danube River basin. The plant's advanced treatment helps safeguard downstream ecosystems, including the Danube wetlands and the Black Sea, by reducing nutrient loads and preventing eutrophication.

The plant discharges into the Danube River basin, which flows through Austria and several other countries before reaching the Black Sea. The Danube is a major European waterway supporting diverse aquatic life and providing drinking water for millions. Advanced treatment at this plant helps reduce nutrient pollution, protecting downstream habitats and maintaining water quality in the sensitive Danube delta ecosystem.
