ROWP Primaria Saulesti Bibesti - Advanced Wastewater Treatment in Bobaia, Romania

ROWP Primaria Saulesti Bibesti is an advanced wastewater treatment plant located in Bobaia, a village in Aninoasa commune, Gorj County, Romania. The plant serves a small population of 299 residents, reflecting its role in rural wastewater management within the Jiu River basin. The plant employs advanced treatment processes, which go beyond secondary treatment to remove nutrients and other pollutants. With a design capacity of 600 m³/day and a current discharge volume of 44.93 m³/day, the facility operates well below its capacity, indicating potential for future growth. As a Romanian plant, it falls under the EU Urban Waste Water Treatment Directive (91/271/EEC), which mandates appropriate treatment levels based on receiving water sensitivity. The treated effluent is discharged into local watercourses that ultimately flow into the Jiu River, a major tributary of the Danube. The Danube then carries the water to the Black Sea. The plant's advanced treatment helps protect downstream aquatic ecosystems, including the Danube Delta, a region of high ecological value.

The plant discharges into small streams that feed the Jiu River, which flows southward to join the Danube in southern Romania. The Danube then empties into the Black Sea via the Danube Delta. The Jiu River supports diverse aquatic life and is important for local fisheries. Advanced treatment at this plant reduces nutrient loading, helping to prevent eutrophication in downstream water bodies and the Black Sea.
