Depuratore Vasanello 1 - Advanced Wastewater Treatment in Vasanello, Lazio

Depuratore Vasanello 1 is an advanced wastewater treatment facility located in Vasanello, a town in the province of Viterbo, Lazio, Italy. The plant serves a population of approximately 3,450 people, reflecting its role as a small-scale municipal treatment facility in central Italy. The plant employs advanced treatment processes, which go beyond secondary treatment to remove nutrients and other pollutants. With a design capacity of 3,500 m³/day and a current discharge volume of 682.98 m³/day, the facility operates well below its capacity. Under the EU Urban Waste Water Treatment Directive (91/271/EEC), plants serving agglomerations under 10,000 population equivalent are generally required to provide secondary treatment, but advanced treatment may be mandated in sensitive areas. The treated effluent is discharged into local watercourses that ultimately drain into the Tiber River basin, which flows into the Tyrrhenian Sea. The plant's location inland, away from the coast, reduces direct marine impact, but its discharge contributes to the water quality of the Tiber watershed, which supports diverse aquatic life and agricultural activities.

The plant discharges into local streams that are part of the Tiber River basin. The Tiber River flows through central Italy and empties into the Tyrrhenian Sea near Rome. The watershed supports diverse aquatic ecosystems and is used for irrigation and recreation. Advanced treatment helps protect downstream water quality in this ecologically sensitive region.
