Tengelic Szennyviztisztito Telep - Advanced Wastewater Treatment in Tengelic, Hungary

Tengelic Szennyviztisztito Telep is an advanced wastewater treatment facility located in Tengelic, a village in Tolna County, Hungary. The plant serves a population of approximately 1,400 residents, reflecting its role in managing domestic wastewater for this rural community in the Dél-Dunántúl region. As an advanced treatment plant, it goes beyond secondary treatment to remove nutrients such as nitrogen and phosphorus, which is particularly important for protecting sensitive receiving waters. Under the EU Urban Waste Water Treatment Directive (91/271/EEC), Hungary requires advanced treatment for discharges into sensitive areas, and plants serving agglomerations of this scale typically meet secondary treatment standards as a minimum. The treated effluent from the plant is discharged into local watercourses that ultimately drain into the Danube River basin. The Danube flows through Hungary and into the Black Sea, making nutrient removal at this plant important for reducing eutrophication risks in downstream ecosystems. The plant's advanced treatment helps maintain water quality in the region's rivers and supports aquatic biodiversity.

The plant discharges into local streams that are part of the Danube River basin, which flows through Hungary and into the Black Sea. The Danube is a major European waterway supporting diverse aquatic life, including fish species such as sturgeon and migratory birds. Advanced treatment at this plant helps reduce nutrient loads that could contribute to algal blooms and oxygen depletion in downstream waters, protecting the ecological health of the Danube and the Black Sea.
