DP01514001_MELEGNANO Wastewater Treatment Plant, Vizzolo Predabissi, Lombardy

DP01514001_MELEGNANO is a municipal wastewater treatment plant located in Vizzolo Predabissi, a town in the Lombardy region of northern Italy. The plant serves a population equivalent of approximately 26,110, placing it in the medium-agglomeration category under Italian and EU regulations. It is situated in the Po River basin, a densely populated and agriculturally intensive area. Under the EU Urban Waste Water Treatment Directive (91/271/EEC), agglomerations of this size are required to provide secondary treatment or equivalent, with more stringent requirements if the discharge enters a sensitive area. It operates within Italy's national regulatory framework, which implements the directive through Decreto Legislativo 152/2006. The treated effluent is discharged into local watercourses that ultimately drain into the Po River, which flows eastward into the Adriatic Sea. The Po basin supports diverse aquatic life and is an important agricultural and industrial corridor. Proper treatment at plants like this helps protect downstream ecosystems and water quality in the Adriatic coastal zone.

The plant discharges into the Po River basin, which drains into the Adriatic Sea via the Po Delta. The Po River is Italy's longest river and supports a rich ecosystem, including migratory fish species and extensive wetlands in its delta. The basin faces pressures from agriculture, industry, and urban runoff, making effective wastewater treatment critical for maintaining water quality and ecological health in the Adriatic coastal environment.
