ROWP Primaria Voila Wastewater Treatment Plant, Dridif, Brașov County

ROWP Primaria Voila is a municipal wastewater treatment plant located in Dridif, a village in the Voila commune of Brașov County, Romania. The plant serves a small population of 573 residents, reflecting the rural character of the area. The facility provides secondary treatment, which is the standard biological treatment stage required under the EU Urban Waste Water Treatment Directive (91/271/EEC) for agglomerations of this size. With a designed capacity of 250 m³/day and a current discharge volume of 172.61 m³/day, the plant operates below its maximum capacity. The treated effluent is discharged into local watercourses that eventually drain into the Olt River basin, a major tributary of the Danube. The Olt River flows southward through the Carpathian Mountains and into the Danube, which ultimately reaches the Black Sea. The plant plays a key role in protecting the local watershed and downstream aquatic ecosystems from untreated wastewater.

The plant discharges into small streams that feed the Olt River, a significant watercourse in southern Romania. The Olt River basin supports diverse aquatic life and provides water for agriculture and communities. Downstream, the Olt joins the Danube, which flows into the Black Sea. The plant's secondary treatment helps reduce organic pollution and nutrient loads, safeguarding the ecological health of these waters.
