ARA Wallsee 3044 AM - Advanced Wastewater Treatment in Wallsee-Sindelburg, Austria

ARA Wallsee 3044 AM is an advanced wastewater treatment plant located in Wallsee-Sindelburg, in the state of Niederösterreich, Austria. The facility serves a population of 2,295 and is part of the municipal wastewater infrastructure for the region. The plant provides advanced treatment, which goes beyond the secondary treatment required by the EU Urban Waste Water Treatment Directive (91/271/EEC) for agglomerations of this size. With a designed capacity of 2,700 m³/day and a current discharge volume of 455.71 m³/day, the plant operates well within its capacity. The treated effluent is discharged 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 providing water for millions of people. The plant's advanced treatment helps protect these downstream environments.

The plant discharges into the Danube River basin, which flows through Central and Eastern Europe before reaching the Black Sea. The Danube supports a rich diversity of fish and bird species, including several migratory fish. Advanced treatment at this plant helps reduce nutrient loads and pollutants, contributing to the ecological health of the river and its delta.
