Gyongyostarjan Szennyviztisztito Telep - Advanced Wastewater Treatment in Gyöngyöstarján, Hungary

Gyongyostarjan Szennyviztisztito Telep is an advanced wastewater treatment facility located in Gyöngyöstarján, a town in Heves County, northern Hungary. The plant serves a population of about 2,002 people, reflecting its role as a small-scale municipal treatment works 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 1,666 m³/day and a current discharge volume of 236 m³/day, the facility operates well below its capacity. Under Hungarian and EU regulations, advanced treatment is typically required for sensitive areas or larger agglomerations, but here it ensures high effluent quality for the local environment. The treated effluent is discharged into local watercourses that drain into the Tisza River basin, ultimately reaching the Danube River and the Black Sea. The plant's advanced treatment helps protect downstream aquatic ecosystems, including the Tisza River, which supports diverse fish populations and is an important ecological corridor in the Carpathian Basin.

The plant discharges into small streams that flow into the Tisza River, a major tributary of the Danube. The Tisza basin supports diverse aquatic life and is an important migratory route for fish. Advanced treatment reduces nutrient loading, helping to prevent eutrophication in downstream waters, including the Danube Delta and the Black Sea.
