SAN GEMINI FAVAZZANO Wastewater Treatment Plant, Acquavogliera, Umbria

SAN GEMINI FAVAZZANO is an advanced wastewater treatment plant located in Acquavogliera, a locality near San Gemini in the Umbria region of Italy. The plant serves a small population of 1,337 and is designed to handle a capacity of 2,500 cubic meters per day. It operates under Italy's implementation of the EU Urban Waste Water Treatment Directive (91/271/EEC), which mandates appropriate treatment for agglomerations of this scale. The plant employs advanced treatment processes, which go beyond secondary treatment to remove nutrients and other pollutants. This level of treatment is typical for sensitive areas where receiving waters require higher protection. The plant discharges a treated volume of approximately 264.68 cubic meters per day, indicating a utilization rate well below its designed capacity. The treated effluent is discharged into local watercourses that ultimately drain into the Tiber River basin, which flows through Umbria and Lazio before reaching the Tyrrhenian Sea. The plant plays a key role in protecting the water quality of the Tiber watershed, supporting aquatic ecosystems and downstream uses such as agriculture and recreation.

The plant discharges into the Tiber River basin, which flows through central Italy and empties into the Tyrrhenian Sea near Rome. The Tiber supports diverse aquatic life and is an important water resource for the region. Advanced treatment helps reduce nutrient loading, protecting downstream ecosystems from eutrophication and maintaining water quality for sensitive habitats.
