Sarospatak Szennyviztisztito Telep - Sárospatak Wastewater Treatment Plant, Hungary

Sarospatak Szennyviztisztito Telep is a municipal wastewater treatment facility located in Sárospatak, a town in the Borsod-Abaúj-Zemplén county of northern Hungary. The plant serves a population of approximately 16,510, classifying it as a medium-sized agglomeration under EU classification. As a plant in Hungary, which is an EU member state, it operates under the EU Urban Waste Water Treatment Directive (91/271/EEC). This directive requires secondary treatment for agglomerations of this size, with more stringent tertiary treatment if the receiving waters are designated as sensitive areas. The regulatory framework ensures compliance with EU standards. The treated effluent is discharged into the local water system, which ultimately drains into the Tisza River basin, a major tributary of the Danube River. The Danube flows into the Black Sea, making this plant part of a large transboundary watershed. The plant plays a key role in protecting the water quality of the Bodrog River and downstream ecosystems.

The plant discharges into the Bodrog River, a tributary of the Tisza River, which flows into the Danube and eventually the Black Sea. This watershed supports diverse aquatic life and is important for migratory fish species. The region's water quality is influenced by agricultural runoff and industrial activities, making effective wastewater treatment critical for maintaining ecological balance.
