Kleinzicken Tauchental Wastewater Treatment Plant, Kotezicken, Burgenland

Kleinzicken Tauchental is a wastewater treatment plant located in Kotezicken, a locality in the municipality of Mischendorf, Bezirk Oberwart, Burgenland, Austria. The plant serves a population of approximately 2,791 people and has a designed capacity of 4,000 m³/day, with an actual discharge volume of 796.78 m³/day. The plant employs advanced treatment processes, which go beyond secondary treatment to remove nutrients and other pollutants. As an Austrian facility, it operates under the EU Urban Waste Water Treatment Directive (91/271/EEC), which requires advanced treatment for agglomerations discharging into sensitive areas. For a plant of this scale (under 10,000 population equivalent), the directive mandates appropriate treatment to protect receiving waters. The treated effluent is discharged into local watercourses that drain into the Pinka River, a tributary of the Raab River, which flows into the Rába River and ultimately reaches the Danube River basin. The plant plays a key role in protecting the water quality of these streams and the downstream aquatic ecosystems in the Burgenland region.

The plant discharges into small streams that feed the Pinka River, which flows into the Raab River, a tributary of the Danube. This watershed supports diverse aquatic life and is part of the larger Danube basin, which is ecologically significant for migratory fish and wetland habitats. The advanced treatment helps reduce nutrient loading, protecting downstream water bodies from eutrophication.
