WV Abwasserverband Volkermarkt Jaunfeld Tainach - Advanced Wastewater Treatment in Eberndorf, Austria

WV Abwasserverband Volkermarkt Jaunfeld Tainach is an advanced wastewater treatment plant located in Kohldorf, Eberndorf, in the Bezirk Völkermarkt region of Kärnten, Austria. The plant serves a population of 1,647 and has a designed capacity of 2,000 m³/day, with an average discharge volume of 211.71 m³/day. As a small agglomeration, it plays a key role in managing local wastewater in this rural area of southern Austria. The plant employs advanced treatment processes, which go beyond the secondary treatment required by the EU Urban Waste Water Treatment Directive (91/271/EEC) for agglomerations of this size. This level of treatment ensures high-quality effluent, reducing nutrients and pollutants before discharge. The plant operates under Austrian national regulations that implement EU directives, with permits issued by the relevant state authority in Kärnten. The treated effluent is discharged into local water bodies that eventually drain into the Drava River, a major tributary of the Danube. The Drava River flows through Slovenia, Croatia, and Hungary before joining the Danube, supporting diverse aquatic ecosystems along its course. The plant's advanced treatment helps protect these downstream environments from nutrient pollution and other contaminants.

The plant discharges into local streams that feed the Drava River, which flows through Slovenia, Croatia, and Hungary before reaching the Danube and ultimately the Black Sea. The Drava River supports diverse aquatic life, including fish species such as the Danube salmon and various migratory birds. Advanced treatment at this plant helps maintain water quality in this ecologically sensitive river system, reducing nutrient loads that could cause eutrophication in downstream reservoirs and the Danube Delta.
