ROWP SPGL SA Floresti Wastewater Treatment Plant, Cătina, Prahova, Romania

ROWP SPGL SA Floresti is a municipal wastewater treatment plant located in Cătina, a village within the Florești commune, Prahova County, Romania. The plant serves a population of approximately 2,743 people, reflecting its role in managing domestic wastewater for this rural community. 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 between 2,000 and 10,000. With a designed capacity of 7,733 m³/day and a current discharge volume of 392.92 m³/day, the plant operates well below its capacity, indicating potential for future growth or seasonal variability. The treated effluent is discharged into local watercourses that eventually drain into the Prahova River, a tributary of the Ialomița River, which flows into the Danube River and ultimately reaches the Black Sea. The plant's operation helps protect downstream aquatic ecosystems and supports water quality in the Danube basin.

The plant discharges into small streams that feed the Prahova River, part of the Danube River basin. The Prahova River flows through the Carpathian foothills and supports diverse aquatic life, including fish species such as barbel and chub. Downstream, the Ialomița River and the Danube Delta are ecologically sensitive areas that benefit from reduced nutrient and organic pollution from well-treated wastewater.
