Overview
Szentistván Szennyvíztisztító Telep is an advanced wastewater treatment plant serving Szentistván, Hungary. It treats wastewater for approximately 5,102 residents with a designed capacity of 6,174 m³/day.
Szentistván Szennyvíztisztító Telep is an advanced wastewater treatment facility located in Szentistván, a town in Borsod-Abaúj-Zemplén county, northern Hungary. The plant serves a population of approximately 5,102 people, reflecting its role as a key municipal infrastructure for the local community. The plant employs advanced treatment processes, which go beyond secondary treatment to remove nutrients and other pollutants. With a designed capacity of 6,174 m³/day and a current discharge volume of 601.43 m³/day, the facility operates well below its capacity, indicating room for future growth. As a Hungarian plant, it operates under the EU Urban Waste Water Treatment Directive (91/271/EEC), which mandates appropriate treatment levels based on population equivalents and receiving water sensitivity. The treated effluent is discharged into local water bodies that eventually drain into the Tisza River basin, a major tributary of the Danube. The plant's advanced treatment helps protect downstream aquatic ecosystems, including the Tisza's diverse fish populations and the Danube Delta's sensitive wetland habitats.
Environmental context
The plant discharges into the Tisza River basin, which flows southward through Hungary and into Serbia before joining the Danube. The Tisza supports a rich aquatic ecosystem, including over 60 fish species and important bird habitats along its floodplains. Advanced treatment at this plant helps reduce nutrient loads that could otherwise contribute to eutrophication in downstream lakes and the Danube Delta.
