ROWP SC HIDRO PRAHOVA SA sucursala Valeni de Munte SEAU monobloc - Secondary Wastewater Treatment in Vălenii de Munte, Romania

ROWP SC HIDRO PRAHOVA SA sucursala Valeni de Munte SEAU monobloc is a municipal wastewater treatment plant located in Vălenii de Munte, Prahova County, Romania. The plant serves a small population of 211 residents and is situated in the Subcarpathian region, an area characterized by hilly terrain and proximity to the Carpathian Mountains. The plant provides secondary treatment, which is the standard biological treatment stage required under the EU Urban Waste Water Treatment Directive (91/271/EEC) for agglomerations with a population equivalent below 2,000. The designed capacity of 500 m³/day indicates the plant is sized for a small community. The current discharge volume is 2.90 m³/day, suggesting low utilization relative to capacity. The treated effluent is discharged into local watercourses that eventually drain into the Teleajen River, a tributary of the Prahova River, which flows into the Ialomița River and ultimately reaches the Danube River and the Black Sea. The plant plays a key role in protecting the local watershed and downstream aquatic ecosystems from untreated wastewater.

The plant discharges into the Teleajen River basin, which flows through the Prahova Valley and joins the Ialomița River, a major tributary of the Danube. The Danube then empties into the Black Sea. The local watershed supports diverse aquatic life and is part of a region known for its biodiversity, including fish species such as barbel and chub. The plant's secondary treatment helps reduce organic pollution and nutrient loads, protecting downstream water quality.
