Depuratore Centro Storico - Advanced Wastewater Treatment in Vitorchiano, Lazio

Depuratore Centro Storico is an advanced wastewater treatment facility located in Vitorchiano, a town in the Lazio region of central Italy. The plant serves a population of about 1,750 people, reflecting its role in managing municipal wastewater for this small Italian community. Its location along Strada provinciale Valle del Vezza places it within the rural landscape of Viterbo province. The plant employs advanced treatment processes, which go beyond the secondary treatment standard required by the EU Urban Waste Water Treatment Directive (91/271/EEC) for agglomerations of this size. With a designed capacity of 2,600 cubic meters per day and an average discharge volume of 346.44 cubic meters per day, the facility operates well within its capacity, ensuring effective treatment. Advanced treatment typically includes nutrient removal, which is important for protecting sensitive water bodies. Treated effluent from the plant is discharged into the local watershed, which ultimately drains into the Tiber River basin and then into the Tyrrhenian Sea. The plant plays a key role in safeguarding the water quality of local streams and the downstream environment, supporting aquatic life and preventing eutrophication in coastal waters.

The plant discharges into the Valle del Vezza stream, a tributary of the Tiber River. The Tiber flows through central Italy and empties into the Tyrrhenian Sea near Rome. The downstream environment includes ecologically sensitive areas such as the Tiber River delta, which supports diverse aquatic habitats and migratory bird species. Advanced treatment at this plant helps reduce nutrient loads, protecting the river and coastal ecosystem from eutrophication.
