CASTEL_MAGGIORE_TREBBO Wastewater Treatment Plant, Castel Maggiore, Italy

CASTEL_MAGGIORE_TREBBO is an advanced wastewater treatment plant located in Castel Maggiore, a town in the Emilia-Romagna region of northern Italy. The plant serves a population equivalent of 3,350 and has a designed capacity of 3,600 cubic meters per day, with an average discharge volume of 738.97 cubic meters per day. As an advanced treatment facility, it goes beyond secondary treatment to remove nutrients and other pollutants, aligning with the requirements of the EU Urban Waste Water Treatment Directive (91/271/EEC) for sensitive areas. The plant discharges treated wastewater into the local drainage network, which ultimately flows into the Reno River and then into the Adriatic Sea. This inland location, over 50 km from the coast, reduces direct marine impact, but the advanced treatment ensures protection of the Reno River ecosystem and downstream coastal waters.

The plant discharges into the Reno River basin, which flows through the Po Valley and empties into the Adriatic Sea near the Po Delta. The Reno River supports diverse aquatic life and is used for irrigation and recreation. Advanced treatment at this plant helps minimize nutrient loading, protecting the river's ecological health and the sensitive coastal environment of the northern Adriatic.
