ORGIANO_PILASTRO Wastewater Treatment Plant, Cagnano, Veneto, Italy

ORGIANO_PILASTRO is a wastewater treatment facility located in the hamlet of Cagnano, within the municipality of Pojana Maggiore in the Veneto region of northern Italy. The plant serves a small population of 410 people, reflecting its role in a rural or small community setting. It is situated inland, away from coastal areas, and operates under the regulatory framework of the European Union and Italian national water quality standards. The plant provides secondary treatment, which is the minimum standard required under the EU Urban Waste Water Treatment Directive (91/271/EEC) for agglomerations of this size. Secondary treatment typically involves biological processes to reduce organic matter and suspended solids. The designed capacity of 500 m³/day indicates the plant's potential to handle higher loads, while the current discharge volume of 81.17 m³/day suggests it operates well below capacity. The treated effluent is discharged into local watercourses that eventually drain into the Po River basin, one of Italy's most significant hydrological systems. The Po River flows eastward into the Adriatic Sea, supporting diverse aquatic life and agricultural activities along its course. The plant's operation helps protect the local watershed from untreated sewage, contributing to the ecological health of the region's waterways.

The plant discharges into the Po River basin, which drains into the Adriatic Sea. This watershed supports a variety of aquatic species and is important for irrigation and drinking water supply in the Po Valley. The secondary treatment process reduces organic pollutants, helping to maintain water quality in downstream ecosystems, including the Po Delta, a region of high ecological value.
