ROWP VLADENI Wastewater Treatment Plant, Spineni, Iași County, Romania

ROWP VLADENI is a municipal wastewater treatment plant located in Spineni, a village in Andrieșeni commune, Iași County, Romania. The plant serves a population of 662 and has a designed capacity of 783 cubic meters per day, with an average discharge volume of 102.16 cubic meters per day. 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. As a smaller facility serving fewer than 2,000 people, it falls below the directive's mandatory threshold, but still operates under Romanian national regulations aligned with EU standards. The treated effluent is discharged into local watercourses that drain into the Prut River basin, which flows into the Danube River and ultimately the Black Sea. The plant plays a role in protecting local streams and groundwater from untreated sewage, supporting the ecological health of the region's agricultural landscape.

The plant discharges into small tributaries of the Prut River, which flows into the Danube and then the Black Sea. The surrounding area is predominantly agricultural, with the plant helping to prevent nutrient pollution that could lead to eutrophication in downstream water bodies. The Prut River basin supports diverse aquatic life and is an important ecological corridor in eastern Romania.
