ROWP Primaria Saulesti - Advanced Wastewater Treatment in Dolcești, Gorj County

ROWP Primaria Saulesti is an advanced wastewater treatment plant located in Dolcești, Săulești, Gorj County, Romania. The plant serves a small population of 417 residents and has a designed capacity of 750 m³/day, with a discharge volume of 82.94 m³/day. As an advanced treatment facility, it goes beyond secondary treatment to remove nutrients and other pollutants, meeting stringent effluent standards. In Romania, such plants operate under the EU Urban Waste Water Treatment Directive (91/271/EEC), which requires appropriate treatment for discharges into sensitive areas. The plant's treated effluent is discharged into local watercourses that eventually drain into the Jiu River, a tributary of the Danube. This contributes to the protection of the Danube River Basin, supporting aquatic ecosystems and downstream water quality.

The plant discharges into local streams that flow into the Jiu River, which joins the Danube and ultimately reaches the Black Sea. The Jiu River supports diverse aquatic life and is part of the Danube River Basin, one of Europe's most important ecological corridors. Advanced treatment helps reduce nutrient loading, protecting downstream ecosystems from eutrophication.
