FONZASO_FENADORA Wastewater Treatment Plant, Frassené, Veneto, Italy

FONZASO_FENADORA is an advanced wastewater treatment plant located in the hamlet of Case Balzan, near Frassené, in the municipality of Fonzaso, Belluno province, Veneto, Italy. The plant serves a population of about 3,611 people, placing it in the small agglomeration category under Italian and EU regulations. The plant employs advanced treatment processes, which go beyond secondary treatment to remove nutrients and other pollutants. It has a designed capacity of 4,400 m³/day and currently discharges approximately 714.85 m³/day of treated wastewater. As an Italian facility, it operates under the EU Urban Waste Water Treatment Directive (91/271/EEC), which requires appropriate treatment for discharges into sensitive areas. The treated effluent is discharged into the local water system, which ultimately drains into the Piave River basin and then into the Adriatic Sea. The plant plays a key role in protecting the water quality of the Piave River and the downstream environment, supporting aquatic life and reducing nutrient loads to the Adriatic.

The plant discharges into the Piave River basin, which flows through the Veneto region and empties into the Adriatic Sea near Venice. The Piave River supports diverse aquatic ecosystems and is an important water resource for agriculture and tourism. Advanced treatment at this plant helps reduce nutrient pollution, protecting downstream habitats and the sensitive coastal environment of the northern Adriatic.
