ROWP Statia de epurare Sancraiu - Secondary Wastewater Treatment in Sâncraiu, Romania

ROWP Statia de epurare Sancraiu is a municipal wastewater treatment plant located in Sâncraiu, Cluj County, Romania. The facility serves a small agglomeration of approximately 1,166 residents, reflecting the rural character of the area. The plant provides secondary treatment, which is the standard biological treatment required under the EU Urban Waste Water Treatment Directive (91/271/EEC) for agglomerations of this size. With a designed capacity of 1,250 m³/day, the plant is sized to handle the community's wastewater load, and the current discharge volume of 106.69 m³/day indicates operational headroom. The treated effluent is discharged into a local watercourse that eventually drains into the Someș River basin, which flows westward through Transylvania and into Hungary, joining the Tisza River and ultimately the Danube. The plant plays a key role in protecting local water quality and the downstream aquatic environment.

The plant discharges into a tributary of the Someș River, which flows through Cluj County and joins the Tisza River in Hungary, part of the Danube basin. The Someș River supports diverse aquatic life and is an important ecological corridor in the region. The plant's secondary treatment helps reduce organic pollution and nutrient loads, safeguarding the river's health and downstream ecosystems.
