ROWP Primaria Saulesti Dolcesti - Advanced Wastewater Treatment in Frasin, Gorj, Romania

ROWP Primaria Saulesti Dolcesti is an advanced wastewater treatment plant located in Frasin, within the Vladimir commune of Gorj County, Romania. The plant serves a population of approximately 770 residents, reflecting a small-scale municipal facility typical of rural communities in the region. The plant provides advanced treatment, which goes beyond secondary treatment to remove nutrients and other pollutants. With a designed capacity of 600 cubic meters per day and an actual discharge volume of 76.90 cubic meters per day, the facility operates well below its capacity. As a Romanian plant, it operates under the EU Urban Waste Water Treatment Directive 91/271/EEC, which requires appropriate treatment for agglomerations of this size. The treated effluent is discharged into local water bodies that ultimately drain into the Jiu River basin, a major tributary of the Danube. The Danube then flows into the Black Sea, making this plant part of a large international watershed. Advanced treatment helps protect downstream aquatic ecosystems and supports water quality goals in the region.

The plant discharges into local streams that feed into the Jiu River, which flows southward to join the Danube River. The Danube carries water through several countries before reaching the Black Sea. This watershed supports diverse aquatic life and is important for migratory fish species. Advanced treatment at this plant helps reduce nutrient loading, which can otherwise contribute to eutrophication in downstream water bodies.
