Nograd Szennyviztisztito Telep is an advanced wastewater treatment facility located in Diósjenő, a town in Nógrád County, northern Hungary. The plant serves a population of approximately 2,978 people, making it a small-scale municipal treatment facility in the region. The plant employs advanced treatment processes, which go beyond secondary treatment to remove nutrients and other pollutants. With a designed capacity of 3,250 m³/day and an actual discharge volume of 351.05 m³/day, the plant operates well below its capacity. As a Hungarian facility, it operates under the national implementation of the EU Urban Waste Water Treatment Directive (91/271/EEC), which requires appropriate treatment levels based on the sensitivity of receiving waters. The treated effluent is discharged into local waterways that eventually drain into the Danube River basin, contributing to the Black Sea catchment. The plant plays a key role in protecting the local environment and downstream water quality in the Danube watershed.
Environmental context
The plant discharges into small streams in the Nógrád region, which flow into the Ipoly River (Ipeľ), a tributary of the Danube. The Danube then carries the water through Hungary and the Balkan region to the Black Sea. The local watershed supports diverse aquatic life and is part of the Danube River Basin, one of Europe's most ecologically significant river systems. The advanced treatment helps reduce nutrient loading, protecting downstream ecosystems from eutrophication.
