Noszvaj Szennyviztisztito Telep - Advanced Wastewater Treatment in Szomolya, Hungary

Noszvaj Szennyviztisztito Telep is an advanced wastewater treatment facility located in Szomolya, within the Mezőkövesd district of Borsod-Abaúj-Zemplén county, Hungary. The plant serves a population of 2714 and has a designed capacity of 4600 m³/day, with a discharge volume of 319.93 m³/day, indicating it operates well below its capacity. As an advanced treatment plant, it goes beyond secondary treatment to remove nutrients such as nitrogen and phosphorus, which is typical for facilities discharging into sensitive water bodies under Hungarian and EU regulations. The plant operates under the EU Urban Waste Water Treatment Directive (91/271/EEC), which requires advanced treatment for agglomerations serving over 10,000 people in sensitive areas, though this plant serves a smaller population. The treated effluent is discharged into local waterways that eventually drain into the Tisza River basin, a major tributary of the Danube. The Tisza River supports diverse aquatic ecosystems and is an important migratory corridor for fish species. The advanced treatment helps protect downstream water quality in the Tisza and Danube rivers.

The plant discharges into local streams that flow into the Tisza River, a major tributary of the Danube River. The Tisza basin supports diverse aquatic life, including fish species such as pike and catfish, and is an important ecological corridor in Central Europe. Advanced treatment at this plant helps reduce nutrient loading, protecting downstream water quality in the Tisza and Danube rivers.
