ROWP Romuli Wastewater Treatment Plant, Romuli, Bistrița-Năsăud, Romania

ROWP Romuli is a municipal wastewater treatment plant located in Romuli, Bistrița-Năsăud County, Romania. Serving a population of approximately 650 people, it is classified as a small agglomeration under Romanian and EU regulations. The plant provides secondary treatment, which is the minimum standard required by the EU Urban Waste Water Treatment Directive (91/271/EEC) for freshwater discharges from agglomerations of this size. As a secondary treatment facility, ROWP Romuli employs biological processes to reduce organic matter and suspended solids before discharge. The plant has a designed capacity of 2,527 cubic meters per day and currently treats an average daily volume of about 124 cubic meters, indicating ample reserve capacity for future growth. Its operations are subject to Romanian national water quality standards, which transpose EU directives. The treated effluent from ROWP Romuli is discharged into a local watercourse that eventually drains into the Someș River, a major tributary of the Tisza River, which flows into the Danube and ultimately the Black Sea. By treating wastewater to secondary standards, the plant helps protect the ecological health of the Someș catchment and downstream aquatic habitats, supporting biodiversity and water quality in the region.

The plant discharges into a local stream that feeds into the Someș River, part of the Tisza-Danube basin. This watershed supports diverse aquatic life and is important for regional water resources. The secondary treatment provided by ROWP Romuli reduces organic pollution and nutrient loads, helping to maintain the ecological balance of downstream rivers and the Black Sea coastal zone.
