Document Description
EBMUD is pursuing development of a project to address seismic improvements for its existing Claremont Tunnel, which crosses the active Hayward fault. The Claremont Tunnel delivers up to 175 million gallons per day of treated water to EBMUD customers west of the Oakland/Berkeley Hills. In a large-magnitude earthquake on the Hayward fault, the Tunnel is expected to be severely damaged by fault offset and groundshaking. The purpose of the project is to ensure that sufficient water is available to customers served by the Claremont Tunnel following an earthquake. EBMUD is currently considering a number of alternatives to serve this purpose, including upgrading the existing Tunnel and reinforcing the Tunnel liner, constructing a bypass tunnel at the Hayward fault crossing, constructing a new tunnel, constructing a new pipeline, or constructing a combination of these elements.
