The New Peschiera Aqueduct: the project
Almost ninety years after work began on the Peschiera Aqueduct, the project to build its new upper section is taking shape. It is Europe's largest water infrastructure project: a strategic investment to ensure water supply continuity and security for Rome and Central Italy.
Inaugurated on 4 November 1949, the Peschiera Aqueduct is the main water supply system serving the metropolitan area of Rome.
The aqueduct extends for 130 km from the spring area located in the municipality of Castel Sant’Angelo, in the province of Rieti, serving 151 municipalities along its route. With a flow rate of approximately 14 m³/s (including the contribution of the Le Capore springs), it supplies a total of around 4 million people.
The New Peschiera Aqueduct: the project
To ensure Rome’s water security, the New Peschiera Aqueduct project has been launched. The project includes the construction of the New Upper Section, which extends from the Peschiera springs to the Salisano plant and optimises conveyance capacity up to 10 m³/s (corresponding to the concession flow rate).
The new line of the Peschiera Aqueduct is designed to ensure service continuity and the highest level of protection for the water resource, safeguarding it for future generations.
