BOBBIO Wastewater Treatment Plant, Bobbio, Emilia-Romagna, Italy

The BOBBIO wastewater treatment plant is located in Bobbio, a town in the province of Piacenza, Emilia-Romagna, Italy. It serves a population of approximately 4,989 residents, treating municipal wastewater from the local community. The plant employs advanced treatment processes, which go beyond secondary treatment to remove nutrients and other pollutants. With a designed capacity of 6,000 m³/day and an average discharge volume of 950.52 m³/day, it operates well within its capacity. Under the EU Urban Waste Water Treatment Directive (91/271/EEC), plants serving agglomerations of this size are required to provide secondary treatment, and the advanced level here exceeds that standard. Treated effluent is discharged into the local water environment, likely the Trebbia River, which flows through the Val Trebbia valley. The river is a tributary of the Po River, Italy's longest river, which ultimately drains into the Adriatic Sea. The plant plays a key role in protecting the Trebbia River's water quality and the downstream Po River ecosystem.

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