Gyongyos Szennyviztisztito Telep - Gyöngyös Wastewater Treatment Plant, Hungary

Gyongyos Szennyviztisztito Telep is the municipal wastewater treatment facility for Gyöngyös, a city in Heves County, northern Hungary. The plant serves a population of around 44,558, placing it in the medium agglomeration category under Hungarian and EU regulations. As a Hungarian facility, the plant operates under the EU Urban Waste Water Treatment Directive (91/271/EEC), which requires secondary treatment for agglomerations of this size. The directive also mandates more advanced treatment if the receiving waters are designated as sensitive areas. The plant's treatment processes are designed to meet these standards, ensuring compliance with national and EU water quality requirements. The treated effluent is discharged into local watercourses that ultimately 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. Proper treatment at this plant helps protect downstream water quality and ecological health.

The plant discharges into the Tisza River basin, which flows southward through Hungary and into Serbia before joining the Danube. The Tisza is a vital ecological corridor, supporting diverse fish populations and migratory birds. Downstream, the Danube Delta is a large wetland ecosystem that provides critical habitat for numerous species. Effective wastewater treatment at Gyongyos helps reduce nutrient loading and pollution in this transboundary river system.
