ROWP Primaria Varvoru de Sus - Advanced Wastewater Treatment in Vârvor, Dolj County

ROWP Primaria Varvoru de Sus is a small advanced wastewater treatment plant located in Vârvor, Dolj County, Romania. It serves a population of 91 and is part of the municipal infrastructure managed by the local authority. The plant is situated in the Zona Metropolitană Craiova, reflecting its role in the broader regional wastewater network. The plant provides advanced treatment, which goes beyond the secondary treatment required by the EU Urban Waste Water Treatment Directive (91/271/EEC) for agglomerations under 2,000 population equivalent. Its designed capacity is 1,126 m³/day, with a current discharge volume of 20.39 m³/day, indicating significant spare capacity. The facility operates under Romanian national regulations that transpose EU directives, ensuring compliance with discharge standards. The treated effluent is discharged into the local environment, ultimately draining into the Jiu River basin and then the Danube River. The Danube flows into the Black Sea, making this plant part of a large international watershed. The advanced treatment helps protect downstream aquatic ecosystems and supports water quality in the region.

The plant discharges into the Jiu River basin, a tributary of the Danube River, which flows into the Black Sea. The Danube Delta is a major ecological zone supporting diverse aquatic life and migratory bird populations. Advanced treatment at this plant helps reduce nutrient loading and protects downstream water quality in this sensitive transboundary watershed.
