Nikitsch Wastewater Treatment Plant, Burgenland, Austria

The Nikitsch wastewater treatment plant is located in the village of Nikitsch/Filež in the district of Oberpullendorf, Burgenland, Austria. It serves a population of 742, making it a small-scale municipal facility in a rural setting. The plant provides secondary treatment, which is the standard biological treatment required under the EU Urban Waste Water Treatment Directive (91/271/EEC) for agglomerations with a population equivalent between 2,000 and 10,000. Secondary treatment typically involves biological oxidation and sedimentation to reduce organic matter and suspended solids. The plant has a designed capacity of 2,800 m³/day and currently discharges an average of 483.31 m³/day, indicating ample reserve capacity. The treated effluent is discharged into a local watercourse, which ultimately drains into the Danube River basin via the Rába or other tributaries. This contributes to the protection of the Danube's ecological health, supporting diverse aquatic life and maintaining water quality for downstream communities and ecosystems.

The plant discharges into a small stream in the Burgenland region, which flows into the Rába River and eventually the Danube River. The Danube is a major European waterway supporting diverse aquatic ecosystems, including fish species such as sturgeon and migratory birds. The plant's secondary treatment helps reduce nutrient and organic loads, protecting downstream water quality in the Danube basin.
