Nagybarca uj Szennyviztisztito telep - Secondary Wastewater Treatment Plant in Nagybarca, Hungary

Nagybarca uj Szennyviztisztito telep is a municipal wastewater treatment plant located in Nagybarca, a town in Borsod-Abauj-Zemplen county, northern Hungary. The plant provides secondary treatment for the local community, ensuring compliance with national and EU environmental standards. As a secondary treatment facility, the plant employs biological processes to reduce organic matter and suspended solids. With a designed capacity of 2,488 m³/day, it is sized to handle the wastewater generated by the town. The plant operates under Hungary's implementation of the EU Urban Waste Water Treatment Directive (91/271/EEC), which mandates secondary treatment for agglomerations of this scale. The treated effluent is discharged into a local watercourse, which eventually drains into the Sajo River and then the Tisza River, a major tributary of the Danube. The plant plays a key role in protecting the water quality of these rivers and the broader Danube basin ecosystem.

The plant discharges into a local stream that flows into the Sajo River, a tributary of the Tisza River, which ultimately joins the Danube River before reaching the Black Sea. The Sajo and Tisza rivers support diverse aquatic life and are important for regional biodiversity. Secondary treatment helps reduce nutrient loads, mitigating eutrophication risks in downstream water bodies.
