ROWP Patas Wastewater Treatment Plant, Prigor, Romania

ROWP Patas is a wastewater treatment plant located in Prigor, Caraș-Severin County, Romania. It serves a small population of 773 residents, reflecting its role in rural sanitation infrastructure. The plant is situated inland, away from coastal areas, and its operations are part of Romania's compliance with EU environmental standards. The plant provides secondary treatment, which is the minimum required under the EU Urban Waste Water Treatment Directive (91/271/EEC) for agglomerations of this size. With a designed capacity of 1300 m³/day and a current discharge volume of 17.15 m³/day, the plant operates well below its capacity, indicating potential for future growth or seasonal variations. Secondary treatment typically involves biological processes to reduce organic matter and suspended solids. The treated effluent is discharged into a local watercourse, likely a tributary of the Danube River basin, which ultimately flows into the Black Sea. The plant's operations help protect downstream water quality and aquatic ecosystems, supporting biodiversity in the region's rivers and wetlands.

The plant discharges into a local watercourse within the Danube River basin, which drains into the Black Sea. This watershed supports diverse aquatic life and is important for migratory fish species. The secondary treatment reduces organic pollutants, helping to maintain water quality in downstream rivers and the Black Sea coastal zone.
