Inland Feeder Project
The Metropolitan Water District's Inland Feeder Project
is a system of tunnels and pipelines that will double the water delivery
capacity of the East branch of the State Water Project. It begins in the
Devil Canyon area north of the city of San Bernardino and ties into
Metropolitan's Colorado River Aqueduct south of Lake Perris, near the city of
San Jacinto. Sections of the water line pass through or near the San Bernardino
National Forest and the communities of Highland, Yucaipa, San Bernardino,
Redlands, Riverside, Perris, Moreno Valley, and San Jacinto Valley.
This project consists of four contracts totaling over 90,000 feet of 12-foot diameter water transmission tunnels. The tunnels will be driven through a variety of ground conditions ranging from soils and completely weathered rock near the portals, through sections containing major faults with highly sheared zones to hard granite and metamorphic rocks.
