Depuratore Capranica - Advanced Wastewater Treatment Plant in Capranica, Lazio

Depuratore Capranica is an advanced wastewater treatment plant located in Capranica, a town in the province of Viterbo, Lazio, Italy. The plant serves a population of approximately 4,900 residents, reflecting its role in managing municipal wastewater for this inland community. Its designed capacity of 5,000 cubic meters per day indicates it is sized to handle the local demand. The plant employs advanced treatment processes, which go beyond secondary treatment to remove nutrients and other pollutants. This level of treatment is consistent with Italy's implementation of the EU Urban Waste Water Treatment Directive (91/271/EEC), which requires advanced treatment for sensitive areas. The plant's discharge volume of 970 cubic meters per day suggests it operates well within its capacity. The treated effluent is discharged into a local watercourse that eventually flows into the Tiber River basin, which drains into the Tyrrhenian Sea. By providing advanced treatment, the plant helps protect downstream water quality and supports the ecological health of the Tiber watershed, which is important for both aquatic life and human use.

The plant discharges into a tributary of the Tiber River, which flows through Lazio and into the Tyrrhenian Sea near Rome. The Tiber basin supports diverse aquatic ecosystems and is a critical water resource for the region. Advanced treatment at this plant reduces nutrient loading, helping to prevent eutrophication in downstream waters and protecting the ecological balance of the river and coastal environment.
