ARGELATO Wastewater Treatment Plant, Argelato, Emilia-Romagna, Italy

ARGELATO is an advanced wastewater treatment plant located in Argelato, a town in the Emilia-Romagna region of northern Italy. The plant serves a population of approximately 2,713 residents, making it a small-scale municipal facility within the broader Bologna metropolitan area. The plant employs advanced treatment processes, which go beyond secondary treatment to remove nutrients and other pollutants. With a designed capacity of 4,500 cubic meters per day and an actual discharge volume of 552.66 cubic meters per day, the plant operates well below its capacity, indicating room for future growth. As an Italian facility, it operates under the EU Urban Waste Water Treatment Directive (91/271/EEC), which mandates secondary treatment for agglomerations of this size, but the plant exceeds requirements with advanced treatment. The treated effluent is discharged into local waterways that ultimately drain into the Po River basin, one of Italy's most important hydrological systems. The Po River flows eastward into the Adriatic Sea, supporting diverse aquatic life and agricultural irrigation. The plant's advanced treatment helps protect the sensitive Po Delta ecosystem and the Adriatic coastal environment from nutrient pollution.

The plant discharges into the Reno River basin, which flows through Emilia-Romagna and joins the Po River near the Adriatic Sea. The Po Delta is a ecologically sensitive area that supports diverse aquatic life, including fish species and migratory birds. Advanced treatment at ARGELATO reduces nutrient loads, helping to prevent eutrophication in the Adriatic Sea and protecting the region's water quality.
