ROWP Primaria Valea Doftanei Wastewater Treatment Plant, Teșila, Romania

ROWP Primaria Valea Doftanei is a municipal wastewater treatment plant located in Teșila, a village within the Valea Doftanei commune in Prahova County, Romania. The plant serves a small population of 748 residents, reflecting the rural character of the area. It is situated in the Carpathian foothills, an area known for its forested landscapes and tourism related to the nearby Doftana Valley. The plant provides primary treatment, which involves physical processes such as sedimentation to remove settleable solids. Under the EU Urban Waste Water Treatment Directive (91/271/EEC), agglomerations with a population equivalent (PE) of less than 2,000 are generally not required to have a collecting system or treatment, but Romania has implemented national regulations that may require treatment for smaller communities. The designed capacity of 800 m³/day suggests the plant is sized for the local population, though the actual discharge volume is 12.10 m³/day, indicating low current flow. The treated effluent is likely discharged into a local watercourse that feeds into the Doftana River, a tributary of the Prahova River, which ultimately flows into the Ialomița River and then the Danube. The Danube carries the water to the Black Sea. The plant's operation helps protect the local watershed, which supports aquatic life and recreational activities in the Carpathian region.

The plant discharges into the Doftana River basin, a tributary of the Prahova River, which flows into the Ialomița River and eventually the Danube River, reaching the Black Sea. The watershed is ecologically sensitive, supporting diverse aquatic species and serving as a corridor for migratory fish. The surrounding forested area contributes to water quality but also makes the region vulnerable to pollution from untreated wastewater, highlighting the importance of the plant's primary treatment in reducing solid waste loads.
