ROWP SC Compania de Apa SA Buzau sect Pogoanele - Caragele, Buzău County, Romania

ROWP SC Compania de Apa SA Buzau sect Pogoanele is a municipal wastewater treatment plant located in Caragele, a village in the Buzău County of southeastern Romania. The plant serves a small population of 763 people, reflecting its role in a rural community. It is operated as part of the regional water utility Compania de Apa SA Buzau. 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 (PE) between 2,000 and 10,000. Although the population served here is below 2,000, the plant's design capacity of 5,828 m³/day suggests it is sized to accommodate future growth or seasonal variations. The actual discharge volume is 404.01 m³/day, indicating a low utilization rate. The treated effluent is discharged into local surface waters, likely tributaries of the Buzău River, which flows into the Danube River and ultimately the Black Sea. The plant plays a key role in protecting the local watershed from untreated sewage, supporting water quality in the downstream environment.

The plant discharges into the Buzău River basin, a tributary of the Danube River, which flows into the Black Sea. The downstream environment includes ecologically sensitive areas such as the Danube Delta, a major European wetland that supports diverse aquatic life and migratory birds. Proper treatment at this plant helps reduce nutrient and pollutant loads entering the river system, contributing to the health of the Black Sea coastal ecosystem.
