Overview

Ozd Szennyviztisztito Telep is a municipal wastewater treatment plant serving approximately 12,000 people in Ózd, Hungary. It operates under the EU Urban Waste Water Treatment Directive.

Ozd Szennyviztisztito Telep is a municipal wastewater treatment facility located in Ózd, a town in the Észak-Magyarország region of northern Hungary. The plant serves a population of around 12,000, placing it in the small-to-medium agglomeration category under EU classification. 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. Compliance with the directive ensures a minimum level of treatment. The plant discharges treated effluent into the local watershed, which ultimately drains into the Tisza River basin. The Tisza is a major tributary of the Danube, flowing through Hungary and several neighboring countries before reaching the Black Sea. The plant plays a key role in protecting the water quality of the Sajó River, a local tributary, and the broader Tisza ecosystem.
