Visitors to San Andreas Trail with an astute eye may observe water levels in San Andreas Reservoir rising late this spring as our new Crystal Springs Pump Station is tested during its final stages of construction. Located near Crystal Springs Dam, the new pump station will be able to transport water from Crystal Springs Reservoir to San Andreas Reservoir with 1/3 more capacity and using less power than the old pump station, which was last substantially upgraded in the 1920s. During the testing period this spring, San Andreas Reservoir is expected to rise approximately six feet.

Like the Crystal Springs-San Andreas Transmission System, the regional water treatment plant is also undergoing major seismic and capacity upgrades as part of the Water System Improvement Program (WSIP). The Contractor has completed pouring the base for the new 11-million gallon treated water reservoir. Crews continue to work on the addition of new filters, seismic retrofits of critical processing units, and upgrades to electrical and other systems.
We can genuinely say the Hetch Hetchy Water System is more seismically reliable today than it was a year ago. Upon completion of construction, the HTWTP will be able to sustain a capacity of 140 million gallons per day (MGD), for up to 60 days, within 24 hours following a major earthquake on the San Andreas Fault.
