Vaja Szennyviztisztito Telep - Berkesz, Hungary Wastewater Treatment Plant

Vaja Szennyviztisztito Telep is a municipal wastewater treatment plant located in Berkesz, within the Észak-Alföld region of Hungary. The facility serves a population of approximately 5,600, classifying it as a small to medium agglomeration under Hungarian and EU regulations. Its location in the Great Plain (Alföld) region places it in a predominantly agricultural and rural setting. The plant provides secondary treatment, which is the standard required by the EU Urban Waste Water Treatment Directive (91/271/EEC) for agglomerations of this size in non-sensitive areas. The designed capacity is 4,100 m³/day, and the current discharge volume is 660.14 m³/day, indicating operational capacity well within design limits. The facility operates under Hungary's national water management framework, which implements EU directives through local permits. Treated effluent from the plant is discharged into the local water network, which ultimately drains into the Tisza River basin, a major tributary of the Danube. The Tisza River supports diverse aquatic life and is an important ecological corridor in Central Europe. Proper treatment helps protect downstream water quality in the Tisza and Danube systems.

The plant discharges into the Tisza River basin, which flows into the Danube River before reaching the Black Sea. The Tisza is a vital waterway for biodiversity, supporting fish species such as pike and catfish, and provides habitat for migratory birds. The region's flat terrain and agricultural land use make nutrient removal important to prevent eutrophication in downstream waters.
