Grosswarasdorf Nebersdorf Langental Wastewater Treatment Plant, Burgenland, Austria

Grosswarasdorf Nebersdorf Langental is an advanced wastewater treatment plant located in the village of Nebersdorf (Šuševo) in the Burgenland region of Austria. The plant serves a small population of 722 residents and has a designed capacity of 2,500 m³/day, with an average discharge volume of 251.66 m³/day. As an advanced treatment facility, the plant goes beyond secondary treatment to remove nutrients and other pollutants, ensuring high-quality effluent. In Austria, wastewater treatment plants are regulated under the Austrian Water Act (WRG 1959) and must comply with EU Urban Waste Water Treatment Directive 91/271/EEC, which requires advanced treatment for sensitive areas. For small agglomerations like this, the plant meets stringent standards to protect local water bodies. The treated effluent is discharged into local streams that flow into the Danube River basin, ultimately reaching the Black Sea. The plant plays a crucial role in safeguarding the region's water quality, supporting aquatic life, and preventing eutrophication in downstream waters. Its advanced treatment ensures minimal environmental impact on the sensitive ecosystems of the Danube watershed.

The plant discharges into small watercourses in the Burgenland region, which are part of the Danube River basin. These streams flow into the Danube, which drains into the Black Sea. The area supports diverse aquatic habitats and is important for migratory fish species. Advanced treatment helps maintain water quality and ecological balance in this sensitive watershed.
