FAENZA Wastewater Treatment Plant, Faenza, Emilia-Romagna, Italy

The FAENZA wastewater treatment plant is located in Faenza, in the Emilia-Romagna region of northern Italy. It serves a population equivalent of 91,644, classifying it as a large agglomeration under EU regulations. The plant is situated inland, approximately 50 km from the Adriatic coast, and its operations are part of the regional water management infrastructure. As a large agglomeration, the plant is subject to the EU Urban Waste Water Treatment Directive (91/271/EEC), which mandates secondary treatment as a minimum, and tertiary treatment if the receiving waters are designated as sensitive areas. The designed capacity is reported as 1.00 (likely in thousands of cubic meters per day), indicating a substantial treatment facility. Regulatory compliance is expected under Italian national law implementing the directive. The treated effluent from the FAENZA plant is discharged into local watercourses that ultimately drain into the Adriatic Sea via the Po River basin. The Po River is the longest river in Italy and supports a diverse aquatic ecosystem, including important fisheries and migratory bird habitats. The plant plays a crucial role in protecting the water quality of the Po River and the Adriatic coastal environment from nutrient pollution and pathogens.

FAENZA lies within the Po River basin, which drains into the northern Adriatic Sea. The Po River and its tributaries support a rich ecosystem, including wetlands and delta areas that are critical for migratory birds and fish species. The plant's discharge contributes to the overall nutrient load in the basin, and its treatment level is essential for preventing eutrophication in the Adriatic, a semi-enclosed sea sensitive to nitrogen and phosphorus inputs.
