ROWP SC Compania de Apa SA Buzau SE Sarata Monteoru Wastewater Treatment Plant, Sărata-Monteoru

ROWP SC Compania de Apa SA Buzau SE Sarata Monteoru is a wastewater treatment plant located in Sărata-Monteoru, a village in Buzău County, Romania. The plant serves a small population of 207 residents and is operated as part of the regional water utility Compania de Apa SA Buzau. Its location in the foothills of the Carpathian Mountains places it in a rural setting with local streams feeding into larger river systems. The plant provides primary treatment, which involves physical processes such as sedimentation to remove settleable solids. With a designed capacity of 1500 m³/day and an actual discharge volume of 132.19 m³/day, the plant operates well below its capacity. Under Romanian and EU regulations, small agglomerations like this are subject to the Urban Waste Water Treatment Directive (91/271/EEC), which requires appropriate treatment based on the sensitivity of the receiving waters. The treated effluent is discharged into local watercourses that eventually drain into the Buzău River, a tributary of the Siret River, which flows into the Danube and ultimately the Black Sea. The plant's operation helps protect downstream aquatic ecosystems and supports water quality in the region's rivers.

The plant discharges into local streams that feed the Buzău River, part of the Danube basin. The Buzău River flows through the Carpathian foothills and supports diverse aquatic life, including fish species such as barbel and chub. Downstream, the river joins the Siret and then the Danube, which empties into the Black Sea. The region's watershed is ecologically sensitive due to its biodiversity and the importance of maintaining water quality for both human use and natural habitats.
