DEP_BELFIORE_LOC_CASTELLETTO Wastewater Treatment Plant, Belfiore, Veneto

DEP_BELFIORE_LOC_CASTELLETTO is a municipal wastewater treatment plant located in Belfiore, a town in the Veneto region of northern Italy. The plant serves a small population of 82 residents and operates with a designed capacity of 100 m³/day, indicating it is sized for local community needs. Its location in the Po River basin places it within a densely populated and agriculturally intensive area. The plant provides secondary treatment, which is the standard required under the EU Urban Waste Water Treatment Directive (91/271/EEC) for agglomerations with a population equivalent below 2,000. Secondary treatment typically involves biological processes to reduce organic matter and suspended solids, ensuring compliance with European effluent standards. The plant's discharge volume of 16.23 m³/day reflects its small scale. The treated effluent is discharged into local watercourses that eventually drain into the Po River, Italy's longest river, which flows into the Adriatic Sea. The Po basin supports extensive agriculture and diverse aquatic ecosystems. Proper treatment at plants like this helps protect downstream water quality and the ecological health of the Adriatic coastal zone.

The plant discharges into tributaries of the Po River, which flows eastward through northern Italy to the Adriatic Sea. The Po basin is a critical agricultural and ecological region, supporting wetlands and migratory bird populations. Effective secondary treatment reduces nutrient loads, helping to mitigate eutrophication risks in the Adriatic Sea.
