Szakoly Szennyviztisztito Telep - Secondary Wastewater Treatment Plant in Szakoly, Hungary

Szakoly Szennyviztisztito Telep is a municipal wastewater treatment facility located in Szakoly, a village in the Nagykállói district of Szabolcs-Szatmár-Bereg county, Hungary. The plant serves a population of 2,934 and operates with a designed capacity of 4,000 m³/day, currently treating 345.87 m³/day of wastewater. It is situated in the Észak-Alföld region, part of the Great Hungarian Plain, an area characterized by flat terrain and agricultural land use. The plant provides secondary treatment, which is the standard biological treatment required under Hungarian and EU regulations for agglomerations of this size. Under the EU Urban Waste Water Treatment Directive (91/271/EEC), settlements with a population equivalent (PE) between 2,000 and 10,000 must have secondary treatment, and Szakoly falls within this category. The plant's capacity utilization is low, indicating ample reserve capacity for future growth or seasonal variations. The treated effluent is discharged into local surface waters that eventually drain into the Tisza River basin, a major tributary of the Danube. The Tisza River supports diverse aquatic ecosystems and is an important water resource for the region. The plant's operation helps protect downstream water quality and contributes to the ecological health of the Tisza catchment area.

The plant discharges into local streams that flow into the Tisza River, which ultimately joins the Danube River before reaching the Black Sea. The Tisza basin is ecologically significant, supporting fish populations such as pike and carp, and providing habitat for migratory birds. The region's flat terrain and agricultural runoff make nutrient management important; secondary treatment helps reduce organic load and protect downstream water bodies from eutrophication.
