Derecske Szennyviztisztito Telep - Secondary Wastewater Treatment in Derecske, Hungary

Derecske Szennyviztisztito Telep is a municipal wastewater treatment plant located in Derecske, in the Észak-Alföld region of Hungary. The plant serves a population of 2,600, classifying it as a small agglomeration under Hungarian and EU regulations. The plant provides secondary treatment, which is the standard required by the EU Urban Waste Water Treatment Directive (91/271/EEC) for settlements of this size. The designed capacity is 8,906 m³/day, and the current discharge volume is 306.49 m³/day, indicating significant spare capacity. The treated effluent is discharged into local surface waters, which ultimately drain into the Tisza River basin. The Tisza River flows southward through Hungary and into Serbia, eventually reaching the Danube River and the Black Sea. The plant plays a key role in protecting local water quality and the downstream aquatic environment.

The plant discharges into the Tisza River basin, which is part of the larger Danube River watershed. The Tisza River supports diverse aquatic life and is an important ecological corridor in Central Europe. Downstream, the Danube Delta is a major wetland ecosystem. The plant's secondary treatment helps reduce nutrient loads and organic pollution, contributing to the health of these water bodies.
