Currently, 58 of the 81 WSIP projects have completed construction between California’s Central Valley and San Francisco along the landmark Hetch Hetchy Regional Water System delivering water to more than 2.6 million people in the Bay Area. WSIP regional projects have exceeded more than four million monitored construction man hours. Since the implementation of the WSIP Safety Approach in April 2009, the total lost time incidence rate is at 2.0 less than half the national average for construction programs.
