ROWP Darabani Wastewater Treatment Plant, Darabani, Botoșani, Romania

ROWP Darabani is a municipal wastewater treatment facility located in Darabani, a town in Botoșani County, northeastern Romania. The plant serves a population of approximately 4,564 residents, classifying it as a small agglomeration under Romanian and EU regulations. The plant provides secondary treatment, which is the minimum standard required by the EU Urban Waste Water Treatment Directive (91/271/EEC) for freshwater discharges from agglomerations of this size. With a designed capacity of 7,661 m³/day and an actual discharge volume of 702.26 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 ultimately drain into the Prut 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.

The plant discharges into the Prut River basin, which flows into the Danube and then the Black Sea. This watershed supports diverse aquatic life and is an important ecological corridor in Eastern Europe. The secondary treatment provided helps reduce nutrient and organic pollution, safeguarding water quality in downstream rivers and the sensitive Black Sea coastal zone.
