Petofibanya Szennyviztisztito Telep - Secondary Wastewater Treatment in Lőrinci, Hungary

Petofibanya Szennyviztisztito Telep is a municipal wastewater treatment plant located in the Selyp district of Lőrinci, in Heves county, northern Hungary. The plant serves a population of 2,300 and is part of the region's water infrastructure under Hungarian and EU regulations. The plant provides secondary treatment, which is the standard biological treatment required under the EU Urban Waste Water Treatment Directive (91/271/EEC) for agglomerations of this size. With a designed capacity of 4,080 m³/day, the plant operates well below its capacity, treating an average of 271.13 m³/day. The treated effluent is discharged into local watercourses that drain into the Tisza River basin, ultimately reaching the Danube River and the Black Sea. The plant plays a key role in protecting local water quality and supporting the ecological health of the region's surface waters.

The plant discharges into the Zagyva River catchment, which flows into the Tisza River, a major tributary of the Danube. The Tisza basin supports diverse aquatic life and is an important ecological corridor in Central Europe. The plant's secondary treatment helps reduce organic pollution and nutrient loads, protecting downstream water quality in the Tisza and Danube rivers.
