A strategic intervention to guarantee the safety and continuity of the water supply service in the capital.
The Ottavia Water Center is one of the main nodes of the capital’s water distribution system. It receives flows from the lower section of the Peschiera Destro pipeline, the Monte Carnale Ottavia adduction pipeline, which allows water transfer from the Peschiera Sinistro system to the Peschiera Destro system.
From the Ottavia Water Centre, water is conveyed via adduction pipelines to the Trionfale node and the Monte Mario reservoir, which serves as the main balancing tank for the central areas of the city. From there, the network continues towards the Aurelio node, supplying the western districts of Rome.
The project involves the construction of a new pipeline approximately 5.2 kilometres in lenght, connecting the Ottavia Water Centre to the new Pineta Sacchetti Water Centre. The intervention will help improve the service provided to the approximately 1 million residents served by Acea Ato 2. The goal is to improve interconnections between aqueduct systems, ensure service continuity even during extraordinary maintenance works, increase flow capacity to the reservoirs, and reduce seismic risk. The project also includes the replacement of obsolete pipes, in order to enhance the efficiency and reliability of the water distribution network.
These interventions are essential to ensuring a safer and more sustainable water supply service for the city of Rome.
The project started in March 2024. Completion is expected by 2026.
Current works involve laying the pipeline along via Sebastiano Vinci.
To allow the installation of the last section, the following road will be closed from Thursday 16 April:
- the section of via Sebastiano Vinci between piazza Santa Maria della Pietà and via Cesare Castiglioni.
- the stretch between via Cesare Castiglioni and via Carlo Livi will be accessible in one direction only, towards the latter.
Traffic changes on nearby roads:
- via Cesare Castiglioni will be passable in one direction only, from via di Torrevecchia;
- from via Carlo Livi, a left turn onto via Sebastiano Vinci will be mandatory;
- in piazza Santa Maria della Pietà, vehicles coming from via Trionfale/San Filippo Neri Hospital will be required to turn left towards via Franco Basaglia/via Trionfale.
Road signs for alternative routes are already in place.
Regarding parking, a 24-hour no-parking zone has been established on via Cesare Castiglioni (up to the public car park entrance) and on via Cesare Lombroso at the intersection with via di Torrevecchia.
Barring unforeseen circumstances, completion of this phase of works is expected by the end of June 2026.
Reliability and resilience
A stronger, more reliable water network and continuous service.
