Tiszaujvaros Szennyviztisztito Telep - Tiszaújváros Wastewater Treatment Plant, Hungary

Tiszaujvaros Szennyviztisztito Telep is the municipal wastewater treatment plant for Tiszaújváros, a town in Borsod-Abaúj-Zemplén county, northern Hungary. Serving a population of around 26,421, the plant is classified as a medium agglomeration under EU regulations. It is located in the Tisza River basin, which is part of the larger Danube River system. As a Hungarian facility, the plant operates under the EU Urban Waste Water Treatment Directive (91/271/EEC), which requires secondary treatment for agglomerations of this size. The directive also mandates more advanced treatment if the receiving waters are designated as sensitive areas. Hungary has transposed these requirements into national law, and the plant is subject to permits issued by the relevant water authority. The plant's treated effluent is discharged into the Tisza River, a major tributary of the Danube. The Tisza flows south through Hungary and into Serbia, eventually reaching the Black Sea. The river supports diverse aquatic life and is an important ecological corridor. Proper treatment helps protect water quality in the Tisza and downstream ecosystems.

The plant discharges into the Tisza River, which flows into the Danube River and ultimately the Black Sea. The Tisza basin is ecologically significant, supporting diverse fish populations and serving as a migratory route for birds. The region's flat terrain and agricultural land use mean that nutrient pollution from wastewater can contribute to eutrophication in downstream water bodies. Effective treatment is essential to maintain the ecological health of the Tisza and Danube systems.
