Ersekvadkert Szennyviztisztito Telep - Advanced Wastewater Treatment in Érsekvadkert, Hungary

Ersekvadkert Szennyviztisztito Telep is an advanced wastewater treatment plant located in Érsekvadkert, a town in Nógrád County, northern Hungary. The plant serves a population of 2,897 and is part of the municipal infrastructure managed under Hungarian water regulations. The plant employs advanced treatment processes, which go beyond secondary treatment to remove nutrients and other pollutants. With a designed capacity of 5,400 m³/day and a current discharge volume of 341.50 m³/day, the facility operates well below its capacity. As a small agglomeration, it falls under the EU Urban Waste Water Treatment Directive, which requires appropriate treatment to protect receiving waters. The treated effluent is discharged into local watercourses that drain into the Ipoly River, a tributary of the Danube. The Danube ultimately flows into the Black Sea. The plant plays a key role in protecting the Ipoly-Danube watershed from nutrient pollution and safeguarding downstream aquatic ecosystems.

The plant discharges into local streams that feed the Ipoly River, which flows into the Danube River and then the Black Sea. The Ipoly-Danube system supports diverse aquatic life and is an important ecological corridor. Advanced treatment helps reduce nutrient loads, preventing eutrophication in downstream waters.
