ROWP Dej is a municipal wastewater treatment facility located in Dej, a city in Cluj County, Romania. The plant serves a population of around 37,302, classifying it as a medium-sized agglomeration under EU standards. Its location in the Transylvanian region places it within a continental climate zone with significant seasonal variations. As a Romanian plant, ROWP Dej operates under the EU Urban Waste Water Treatment Directive (91/271/EEC), which mandates secondary treatment for agglomerations of this size. The directive also requires more advanced treatment if the receiving waters are designated as sensitive areas. The plant's treatment processes are designed to meet these regulatory standards, ensuring compliance with national and EU water quality objectives. The treated effluent from ROWP Dej is discharged into the Someș River, a tributary of the Tisza River, which flows into the Danube and ultimately the Black Sea. The Someș River supports diverse aquatic life and is an important water resource for the region. The plant plays a crucial role in protecting the river's water quality and the downstream ecosystems.
