The San Diego County Water Authority helped delay a legislative hearing about the future of the State Water Project, the 700-mile water system that provides water from Northern California’s rivers to over 25 million state residents. The Water Authority is seeking to lower its own rates, even though it may be increasing others’. The agency hopes the state or the Metropolitan Water District of Southern California will agree to spare San Diego ratepayers certain expenses associated with Gov. Jerry Brown’s $20 billion twin tunnels project. After years of outright skepticism, the Water Authority supports the project, but only under certain conditions.
