OPPEANO_FENILETTO Wastewater Treatment Plant, Oppeano, Veneto, Italy

OPPEANO_FENILETTO is an advanced wastewater treatment plant located in Oppeano, in the Veneto region of northern Italy. The facility serves a population of 4,224 and has a designed capacity of 3,500 m³/day, with an average discharge volume of 836.20 m³/day, indicating it operates well below its design capacity. The plant employs advanced treatment processes, which go beyond secondary treatment to remove nutrients and other pollutants. As an Italian plant serving a small agglomeration, it operates under the EU Urban Waste Water Treatment Directive (91/271/EEC), which requires appropriate treatment for discharges into sensitive areas. Italy's national regulations transpose this directive, and the plant's advanced treatment level suggests it may discharge into a sensitive water body. The treated effluent is discharged into local watercourses that are part of the Po River basin, ultimately draining into the Adriatic Sea. The plant plays a key role in protecting the local aquatic environment and downstream ecosystems, including the Po Delta, which supports diverse wildlife and is an important ecological area.

The plant discharges into the Po River basin, which flows eastward through northern Italy and empties into the Adriatic Sea. The Po Delta is a ecologically sensitive area that supports diverse aquatic life and serves as a critical habitat for migratory birds. Advanced treatment at this plant helps reduce nutrient loading, protecting downstream water quality and the fragile delta ecosystem.
