ROWP SC APAVIL SA Balcesti Wastewater Treatment Plant, Bălcești, Romania

ROWP SC APAVIL SA Balcesti is a municipal wastewater treatment plant located in Bălcești, Vâlcea County, Romania. The plant serves a small agglomeration of approximately 1,094 people, reflecting the rural character of the area. It is situated on Strada 1 Decembrie in the Ulicioiu area of Bărcănești, within the administrative boundaries of Bălcești. The plant provides secondary treatment, which is the standard required by the EU Urban Waste Water Treatment Directive (91/271/EEC) for agglomerations of this size. With a designed capacity of 1,200 m³/day and a current discharge volume of 114.82 m³/day, the facility operates well below its capacity, indicating potential for future growth or seasonal variability. Secondary treatment typically involves biological processes to reduce organic matter and suspended solids. The treated effluent is discharged into a local watercourse that ultimately drains into the Olt River basin, a major tributary of the Danube. The Danube then flows into the Black Sea, making this plant part of a large transboundary watershed. The plant plays a key role in protecting local water quality and downstream ecosystems, including the Danube Delta, a region of high ecological importance.

The plant discharges into a local stream that feeds into the Olt River, a major tributary of the Danube. The Danube flows into the Black Sea, forming the Danube Delta, a vast wetland that supports diverse aquatic life and serves as a critical migratory corridor for birds. The plant's secondary treatment helps reduce nutrient and organic pollution, protecting downstream water quality in this ecologically sensitive region.
