ROWP SC APAVIL SA Daesti Sambotin Wastewater Treatment Plant, Fedeleșoiu, Vâlcea

ROWP SC APAVIL SA Daesti Sambotin is a municipal wastewater treatment plant located in Fedeleșoiu, Vâlcea County, Romania. The plant serves a small community of 302 people and operates under Romania's implementation of the EU Urban Waste Water Treatment Directive (91/271/EEC). The plant provides secondary treatment, which is the standard required by the EU directive for agglomerations of this size. With a designed capacity of 250 m³/day and a current discharge volume of 71.07 m³/day, the plant operates well below its capacity, indicating room for future growth or seasonal variations. The treated effluent is discharged into local water bodies that eventually drain into the Olt River basin, a major tributary of the Danube. The Danube then flows into the Black Sea, making the plant's performance relevant to downstream ecosystems and international water quality agreements.

The plant discharges into the Olt River basin, which flows into the Danube and ultimately the Black Sea. This watershed supports diverse aquatic life and is an important ecological corridor in southeastern Europe. The secondary treatment process helps reduce organic pollutants and nutrients, protecting downstream water quality in a region where agriculture and rural communities rely on healthy waterways.
