Csenger Szennyviztisztito Telep - Advanced Wastewater Treatment in Szamosújlak, Hungary

Csenger Szennyviztisztito Telep is an advanced wastewater treatment plant located in Szamosújlak, a village in the Észak-Alföld region of Hungary. The facility serves a population of approximately 3,800 people, making it a small agglomeration under Hungarian and EU classifications. It is situated inland in the Szabolcs-Szatmár-Bereg county, near the border with Ukraine. The plant employs advanced treatment processes, which go beyond the secondary treatment standard required by the EU Urban Waste Water Treatment Directive (91/271/EEC) for agglomerations of this size. With a designed capacity of 6,930 m³/day and a current discharge volume of 447.95 m³/day, the facility operates well below its capacity, indicating room for future growth or seasonal variations. The plant is operated as part of Hungary's municipal wastewater infrastructure, which is regulated under national law transposing EU directives. The treated effluent is discharged into the local watershed, which ultimately drains into the Tisza River, a major tributary of the Danube. The Tisza River basin supports diverse aquatic life and is an important ecological corridor in Central Europe. The advanced treatment level helps protect downstream water quality in this sensitive river system, which flows through Hungary and into Serbia before joining the Danube.

The plant discharges into the local watershed that feeds the Tisza River, a major tributary of the Danube River basin. The Tisza River supports diverse aquatic ecosystems, including fish species such as carp and catfish, and provides critical habitat for migratory birds. The advanced treatment level helps reduce nutrient loading and protect water quality in this ecologically important river system, which ultimately flows into the Black Sea.
