A number of large population centers in California have developed
their own extensive water projects. The Hetch Hetchy Project
transports Tuolumne River water 156 miles from the Central Sierra
to San Francisco and peninsula cities.
The East Bay Municipal Utility District supplies cities on the
east side of San Francisco Bay with Mokelumne River water.
Many cities rely on local water projects for all or a portion of
their supplies. These projects typically were built and are
operated by local public water districts, county water
departments, city water departments or other special districts.
Nearly 600 special purpose local agencies in California provide
water to their areas through local development projects and
imported supplies. A number of local agencies may also operate
flood control and wastewater treatment facilities in addition to
providing drinking water.
