ROWP SPGC Valea Mare Wastewater Treatment Plant, Delureni, Romania

ROWP SPGC Valea Mare is a municipal wastewater treatment plant located in Delureni, Valea Mare, Vâlcea County, Romania. The plant serves a small population of 636 residents, reflecting its role in a rural or small community setting. It operates under Romania's implementation of the EU Urban Waste Water Treatment Directive (91/271/EEC), which requires secondary treatment for agglomerations of this size. The plant provides secondary treatment, a standard biological process that reduces organic matter and suspended solids. With a designed capacity of 2,800 m³/day, the current discharge volume of 190.71 m³/day indicates low utilization relative to capacity. As a secondary treatment facility, it meets the EU directive's baseline requirements for inland discharges. The treated effluent is discharged into the local water system, eventually reaching the Olt River basin, which flows southward into the Danube River and ultimately the Black Sea. The plant plays a key role in protecting local water quality in the Vâlcea region, supporting downstream aquatic ecosystems and preventing nutrient pollution in the Danube Delta.

The plant discharges into the Olt River basin, a tributary of the Danube River, which flows into the Black Sea. The Olt River supports diverse aquatic life and is an important ecological corridor in southern Romania. The Danube Delta, a major wetland ecosystem, benefits from reduced nutrient loads from upstream treatment plants like this one.
