ARA GAV Fischatal 1876 WU Wastewater Treatment Plant, Gramatneusiedl, Austria

ARA GAV Fischatal 1876 WU is a wastewater treatment plant located in Gramatneusiedl, a town in the district of Bruck an der Leitha in Niederösterreich, Austria. The plant serves a population of approximately 3,581 people, placing it in the small agglomeration category under the EU Urban Waste Water Treatment Directive (UWWTD). As a plant serving fewer than 10,000 people, it is subject to the EU UWWTD requirements for appropriate treatment, which typically involves secondary treatment or equivalent. The plant operates within Austria's regulatory framework, which transposes the EU directive into national law, ensuring that discharges meet quality standards to protect the environment. The treated effluent from the plant is discharged into the local water system, which ultimately drains into the Danube River basin. The Danube is a major European waterway that flows into the Black Sea, supporting diverse aquatic ecosystems and providing water for various uses downstream. The plant plays a key role in protecting the local Feilbach stream and the broader Danube watershed from pollution.

The plant discharges into the Feilbach stream, a tributary of the Danube River. The Danube flows through Central and Eastern Europe before emptying into the Black Sea. This watershed supports a wide range of aquatic life, including fish species such as carp and pike, and provides critical habitat for migratory birds. The plant's treatment helps maintain water quality in this ecologically significant river system.
