San Vicente to Second Aqueduct Pipeline

San Vicente to Second Aqueduct Pipeline


California

The San Vicente to Second Aqueduct Pipeline Tunnel requires mining through a variety of geologic formations including very weak cobble conglomerate to very strong granitic rock.

Deere & Ault prepared a pre-bid evaluation for this 13 mile emergency water supply tunnel in San Diego, California.

Our evaluation of the geotechnical conditions helped the contractor select the appropriate tunneling methods and ground support.
