ROWP Belcesti Wastewater Treatment Plant, Belcești, Iași, Romania

ROWP Belcesti is a municipal wastewater treatment plant located in Belcești, Iași County, Romania. The plant serves a population of 769 and is designed with a capacity of 15,000 m³/day, indicating it is sized to accommodate future growth or seasonal variations. It operates under Romania's implementation of the EU Urban Waste Water Treatment Directive (91/271/EEC), which requires secondary treatment for agglomerations of this scale. The plant provides secondary treatment, a standard biological process that removes organic matter and suspended solids. As a facility serving fewer than 2,000 people, it falls under the EU's 'small agglomeration' category, which mandates appropriate treatment to protect receiving waters. The plant discharges a daily volume of 203.04 m³ of treated effluent. The treated wastewater is discharged into local watercourses that drain into the Prut River basin, eventually reaching the Danube River and the Black Sea. The plant plays a key role in protecting the local watershed from untreated sewage, supporting water quality in the region's agricultural and ecological landscapes.

The plant discharges into the Prut River basin, a major tributary of the Danube River, which flows into the Black Sea. This watershed supports diverse aquatic life and is important for regional biodiversity. The secondary treatment provided helps reduce nutrient and organic pollution, mitigating eutrophication risks in downstream water bodies. The area's agricultural land use makes effective wastewater treatment crucial for preventing contamination of groundwater and surface waters.
