ROWP Cehu Silvaniei Wastewater Treatment Plant - Cehu Silvaniei, Romania

ROWP Cehu Silvaniei is a municipal wastewater treatment plant located in Cehu Silvaniei, Sălaj County, Romania. The plant serves a population of 4,638 and has a designed capacity of 5,400 m³/day, currently treating 768.90 m³/day of wastewater. The plant provides secondary treatment, which is the standard required by the EU Urban Waste Water Treatment Directive (91/271/EEC) for agglomerations between 2,000 and 10,000 population equivalent. This level of treatment effectively removes organic matter and suspended solids, ensuring compliance with European environmental standards. The treated effluent is discharged into local watercourses that eventually drain into the Someș River, a tributary of the Tisza River, which flows into the Danube and ultimately the Black Sea. The plant plays a key role in protecting the water quality of the Someș River basin and downstream ecosystems.

The plant discharges into the Someș River basin, which flows into the Tisza River, a major tributary of the Danube. The Danube Delta, a vast wetland and important ecological area, is the final destination. The Someș River supports diverse aquatic life and is used for irrigation and recreation. The plant's secondary treatment helps reduce nutrient and organic pollution, safeguarding the river's ecological health.
