Project
Description
The San Vicente Pipeline projects are part of the Emergency Storage Project, a system of reservoirs, interconnected pipelines and pumping stations designed to make water available to the San Diego region in the event of an interruption in imported water deliveries.
The 11-mile San Vicente Pipeline will be a large-diameter pipeline connecting San Vicente Reservoir in Lakeside to the Water Authority's Second Aqueduct west of Interstate 15. The pipeline will be built in a tunnel at a depth ranging from 50 to 550 feet underground and will not pass directly under any homes. Tunneling, rather than cut-and-cover trenching, allows the Water Authority to build the pipeline with fewer impacts to land surfaces and the surrounding communities. During emergencies, the San Vicente Pipeline will operate with other Water Authority facilities to deliver water from San Vicente Reservoir to water agencies in the southern half of the county.
Construction of the San Vicente Pipeline project began in 2005 and will be complete in 2010.

Tunneling
Progress Map
San Vicente Pipeline construction activity can only be seen at four tunnel access points. Three tunneling machines have been used to dig the majority of the 11-mile- long tunnel. One of the machines excavated rock using a rotating cutterhead to break the rock into smaller pieces. The other two have used a digging arm equipped with a bucket or rotary cutter to break up the rock. One digger shield machine is currently excavating westward from the Slaughterhouse Shaft towards the Central Shaft to complete the remaining section of tunnel.
Pipe installation is the other major construction component necessary to complete the pipeline. Steel pipe sections 50 feet long and 8.5 feet in diameter are lowered into the tunnel by a crane at the Central Shaft and San Vicente Portal locations. Two pipe segments at a time are hauled on a narrow sled inside the tunnel to the final location for placement. Following pipe installation, the contractor places concrete around the exterior of the pipe to secure it in the tunnel. More than 1,000 pipe sections are being used to build the pipeline. Pipe installation in the western portion of the tunnel from the West Shaft to Central Shaft is expected to be completed by the end of 2009. Once the tunnel is finished on the east side of the project, crews will begin installing pipe between the San Vicente Portal and Central Shaft.
