Miskolc Szennyviztisztito Telep - Municipal Wastewater Treatment Plant in Miskolc, Hungary

Miskolc Szennyviztisztito Telep is the municipal wastewater treatment plant serving Miskolc, the fourth-largest city in Hungary, located in the Észak-Magyarország region. The facility handles wastewater from a population of approximately 198,834, classifying it as a large agglomeration under EU standards. As a plant serving over 150,000 people, it falls under the EU Urban Waste Water Treatment Directive (91/271/EEC), which mandates secondary biological treatment as a minimum, and tertiary treatment if the receiving waters are sensitive. The regulatory framework ensures compliance with EU standards for nutrient removal and effluent quality. The treated effluent is discharged into the Sajó River, which flows through northeastern Hungary before joining the Tisza River, a major tributary of the Danube. The Danube ultimately drains into the Black Sea. The plant plays a critical role in protecting the Sajó and Tisza river ecosystems from nutrient pollution and organic load, supporting aquatic biodiversity and downstream water quality.

The plant discharges into the Sajó River, a tributary of the Tisza River, which flows into the Danube and finally the Black Sea. The Sajó River supports diverse aquatic life and is an important ecological corridor in the Carpathian Basin. The plant's operations help prevent eutrophication and maintain water quality in this sensitive river system, which is vital for regional biodiversity and downstream communities.
