San Cesario sul Panaro Wastewater Treatment Plant, Emilia-Romagna, Italy

The San Cesario sul Panaro wastewater treatment plant is located in the Emilia-Romagna region of northern Italy, serving the town of San Cesario sul Panaro and surrounding areas. The facility manages wastewater for a population of approximately 7,805 residents, operating within Italy's municipal wastewater infrastructure. As a plant serving a medium-sized agglomeration, it falls under the EU Urban Waste Water Treatment Directive 91/271/EEC, which requires secondary treatment for discharges into freshwater bodies. The directive also mandates more advanced treatment if the receiving waters are designated as sensitive areas, such as those prone to eutrophication. The treated effluent is discharged into the local water system, which ultimately drains into the Po River basin and then into the Adriatic Sea. The Po River is Italy's longest river and supports extensive agricultural and ecological systems. Proper treatment helps protect downstream water quality and aquatic habitats.

The plant discharges into the Panaro River, a tributary of the Po River, which flows eastward into the Adriatic Sea. The Po basin is a densely populated and agriculturally intensive region, making nutrient removal critical to prevent eutrophication in the Adriatic. The area supports diverse aquatic life and is an important migratory corridor for birds.
