Tar Szennyviztisztito Telep - Advanced Wastewater Treatment in Jobbágyi, Hungary

Tar Szennyviztisztito Telep is a wastewater treatment facility located in Jobbágyi, within the Pásztói district of Nógrád county in northern Hungary. The plant serves a population of approximately 889 residents, classifying it as a small agglomeration under Hungarian and EU regulations. The plant employs advanced treatment processes, which go beyond the secondary treatment standard required by the EU Urban Waste Water Treatment Directive (91/271/EEC) for agglomerations of this size. It has a designed capacity of 2660 cubic meters per day, with a reported discharge volume of 104.8 cubic meters per day, indicating ample reserve capacity. The treated effluent is discharged into local waterways that ultimately drain into the Tisza River basin, a major tributary of the Danube. The plant's advanced treatment helps protect downstream aquatic ecosystems and supports water quality in the region's surface waters.

The plant discharges into the Zagyva River catchment, which flows into the Tisza River and eventually the Danube River before reaching the Black Sea. The region's water bodies support diverse aquatic life and are important for local agriculture and biodiversity. Advanced treatment reduces nutrient loads, helping to prevent eutrophication in downstream lakes and reservoirs.
