Feletto Rivarolo Wastewater Treatment Plant, Cortereggio, Piemonte

Feletto Rivarolo is a wastewater treatment plant located in Cortereggio, a locality within San Giorgio Canavese, in the province of Torino, Piemonte, Italy. The plant serves a population of approximately 50,236, classifying it as a medium agglomeration under EU regulations. As an Italian facility, the plant operates under the EU Urban Waste Water Treatment Directive (91/271/EEC), which requires secondary treatment for agglomerations between 10,000 and 150,000 population equivalent. The directive also mandates more advanced treatment if the receiving waters are designated as sensitive areas, such as those prone to eutrophication. The plant's treated effluent is discharged into local water bodies that ultimately drain into the Po River basin, one of Italy's most significant watersheds. The Po River flows eastward into the Adriatic Sea, supporting diverse aquatic ecosystems and agricultural activities along its course.

The plant discharges into the Po River basin, which drains into the Adriatic Sea. The Po River is Italy's longest river and supports a rich ecosystem, including migratory fish species and wetland habitats. The downstream environment includes the Po Delta, an ecologically sensitive area that provides critical breeding and feeding grounds for numerous bird species.
