Overview
ARA AV Oberes Schwarzatal 1760 NK serves Gloggnitz, Austria, treating wastewater for about 24,767 people. The plant operates under the EU Urban Waste Water Treatment Directive, ensuring proper treatment before discharge.
ARA AV Oberes Schwarzatal 1760 NK is a municipal wastewater treatment plant located in Gloggnitz, in the state of Niederösterreich, Austria. It serves a population of approximately 24,767, classifying it as a medium-sized agglomeration under EU regulations. The plant is situated in the Schwarzatal valley, a region known for its scenic landscapes and proximity to the Alps. As a plant in Austria, it operates under the EU Urban Waste Water Treatment Directive (91/271/EEC), which mandates secondary treatment for agglomerations of this size. The plant is expected to meet the directive's standards for biological treatment and nutrient removal, particularly given Austria's commitment to high environmental standards. The plant is part of a well-regulated network. The treated effluent is discharged into the local water system, ultimately flowing into the Schwarza River, a tributary of the Leitha River, which drains into the Danube River and eventually the Black Sea. This connection highlights the plant's role in protecting downstream ecosystems, including the Danube Delta, a vital ecological area.
Environmental context
The plant discharges into the Schwarza River, which flows into the Leitha River, a tributary of the Danube. The Danube River basin is one of Europe's most important ecological corridors, supporting diverse aquatic life and migratory fish species. The plant's operations help maintain water quality in this transboundary river system, which ultimately reaches the Black Sea. The surrounding region is characterized by forested hills and agricultural land, making nutrient control critical to prevent eutrophication in downstream waters.
