Szolnok Szennyviztisztito Telep - Szolnok, Hungary Wastewater Treatment Plant

Szolnok Szennyviztisztito Telep is the primary wastewater treatment facility for the city of Szolnok, located in the Észak-Alföld region of Hungary. The plant serves a population of around 82,476, classifying it as a medium-to-large agglomeration under EU regulations. As a Hungarian facility, the plant is subject to 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. The plant's treatment processes are designed to meet these standards, ensuring compliance with national and EU water quality requirements. The treated effluent is discharged into the Tisza River, a major tributary of the Danube. The Tisza River flows southward through Hungary and into Serbia, eventually joining the Danube near Belgrade. This river system supports diverse aquatic life and is an important ecological corridor in the Carpathian Basin. The plant's operations help protect water quality in the Tisza and downstream environments.

The plant discharges into the Tisza River, which flows through the Great Hungarian Plain and eventually joins the Danube River in Serbia. The Tisza is a vital waterway for the region, supporting diverse fish populations and migratory birds. The surrounding watershed is predominantly agricultural, with some industrial activity, making nutrient removal an important consideration for protecting downstream water quality.
