“One day before the 106th anniversary of the San Francisco Earthquake of 1906, Mayor Ed Lee was in San Mateo County on Tuesday to mark a major milestone in securing the region’s water supply in the event of a future major earthquake.
“Lee joined San Francisco Public Utilities Commission general manager Ed Harrington and San Mateo County Supervisor Adrienne Tissier on the banks of the Lower Crystal Springs Reservoir, where improvements to the 124-year-old Crystal Springs Dam have just been completed.
“The dam improvements — which doubled the width of the main spillway and raised the height of a parapet on top of the structure by 9 feet — were part of the SFPUC’s $4.6 billion Water System Improvement Program, which consists of 81 seismic improvements to water delivery pipelines, dams and reservoirs from Hetch Hetchy to San Francisco.
“Harrington said the seismic upgrades “virtually guarantee” the reliability of safe drinking water for 2.6 million Bay Area residents within 24 hours of a major earthquake.
“These projects now serve as our reinforced lifeline to deliver Hetch Hetchy water around the Bay,” Harrington said.
“Five years ago we would not have had the same reliability we have today,” he said.
