ROWP CERTESTI Wastewater Treatment Plant, Cerțești, Galați, Romania

ROWP CERTESTI is a municipal wastewater treatment plant located in Cerțești, Galați County, Romania. It serves a small community of 97 residents, reflecting its role in rural wastewater management. The plant operates under Romania's implementation of the EU Urban Waste Water Treatment Directive (91/271/EEC), which sets standards for treatment levels based on population equivalents. The plant provides secondary treatment, a standard requirement for agglomerations under 2,000 population equivalents in sensitive areas. With a designed capacity of 1,000 m³/day and an actual discharge volume of 11.60 m³/day, the plant operates well below its capacity, indicating low hydraulic loading. This suggests the plant is sized for future growth or seasonal variations. The treated effluent is discharged into local watercourses that ultimately drain into the Siret River, a major tributary of the Danube. The Danube then flows into the Black Sea, making the plant part of a large transboundary river basin. Proper treatment helps protect downstream aquatic ecosystems and water quality in the Danube Delta region.

ROWP CERTESTI discharges into local streams that feed the Siret River, a key tributary of the Danube. The Danube River flows into the Black Sea, supporting diverse aquatic life and important migratory fish species. The plant's secondary treatment helps reduce organic pollutants and nutrients, mitigating eutrophication risks in downstream waters. The region's agricultural landscape also benefits from maintained water quality in the Siret basin.
