ROWP Somcuta Mare Wastewater Treatment Plant - Șomcuta Mare, Maramureș, Romania

ROWP Somcuta Mare is a municipal wastewater treatment plant located on Strada Mihai Eminescu in Șomcuta Mare, Maramureș County, Romania. The facility serves a population of approximately 1,161 residents, classifying it as a small agglomeration under Romanian and EU regulations. The plant provides secondary treatment, which is the minimum required by the EU Urban Waste Water Treatment Directive (91/271/EEC) for freshwater discharges from agglomerations of this size. With a designed capacity of 4,400 m³/day and an average discharge volume of 118.87 m³/day, the plant operates well below its capacity, indicating room for future growth or seasonal variability. The treated effluent is discharged into a local watercourse that ultimately drains into the Someș River, a tributary of the Tisza River, which flows into the Danube and then the Black Sea. The plant plays a key role in protecting the Someș River basin from untreated wastewater pollution, supporting aquatic life and downstream water quality.

The plant discharges into a tributary of the Someș River, part of the Tisza-Danube basin that drains into the Black Sea. The Someș River supports diverse aquatic ecosystems and is used for irrigation and recreation. By providing secondary treatment, the plant reduces organic load and nutrient pollution, helping to prevent eutrophication in downstream waters.
