MEZZANI_MEZZANO INFERIORE Wastewater Treatment Plant, Mezzano Inferiore, Italy

The MEZZANI_MEZZANO_INFERIORE wastewater treatment plant is located in Mezzano Inferiore, a frazione of Sorbolo Mezzani in the province of Parma, Emilia-Romagna, Italy. The plant serves a population of approximately 3,576 residents and is part of the municipal wastewater infrastructure for the area. The plant employs advanced treatment processes, which go beyond secondary treatment to remove nutrients and other pollutants. With a designed capacity of 9,600 m³/day and a current discharge volume of 611.62 m³/day, the plant operates well below 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, but the advanced level here indicates compliance with stricter standards for sensitive areas. The treated effluent is discharged into local water bodies that ultimately drain into the Po River basin, which flows into the Adriatic Sea. The plant plays a key role in protecting the Po River ecosystem and the downstream marine environment from nutrient pollution and other contaminants.

The plant discharges into the Po River basin, which flows eastward through northern Italy into the Adriatic Sea. The Po River supports diverse aquatic life and is an important migratory corridor for fish species. The advanced treatment helps reduce nutrient loads, protecting the river and the Adriatic from eutrophication and maintaining water quality for downstream communities and ecosystems.
