Abaujszanto Szennyviztisztito Telep - Secondary Wastewater Treatment in Abaújszántó, Hungary

Abaujszanto Szennyviztisztito Telep is a municipal wastewater treatment plant located in Abaújszántó, a town in the Borsod-Abaúj-Zemplén county of northern Hungary. The plant serves a population of approximately 5,069 residents, classifying it as a small to medium agglomeration under Hungarian and EU standards. It is situated inland, away from coastal areas, and its operations are part of the regional water management infrastructure. The plant provides secondary treatment, which is the minimum standard required by the EU Urban Waste Water Treatment Directive (91/271/EEC) for agglomerations of this size. The designed capacity of 10,542 m³/day indicates that the facility has been built to accommodate future growth or seasonal peaks. The actual discharge volume is 597.54 m³/day, suggesting a utilization rate well below capacity. The treated effluent is discharged into local water bodies that ultimately drain into the Tisza River basin, a major tributary of the Danube. This places the plant within the larger Danube River Basin District, which is ecologically significant for its biodiversity and as a water resource for multiple countries. Proper treatment helps protect downstream aquatic ecosystems and water quality.

The plant discharges into local streams that flow into the Tisza River, a major tributary of the Danube River. The Tisza basin supports diverse aquatic life and is an important ecological corridor in Central Europe. Secondary treatment reduces organic pollutants and suspended solids, helping to maintain water quality in the downstream river system and ultimately in the Black Sea.
