Hetch Hetchy May Get Improvements

The aging Hetch Hetchy system that delivers water to more than two million people in the San Francisco Bay area needs a seismic retrofit. Voters will decide this November whether to let the city issue a one-point-six billion dollar bond measure to help pay for the work. The San Francisco Board of Supervisors voted eight to three last night to put the bond on the ballot.

The money would help finance three-point-six billion dollars in construction on Hetch Hetchy. The system supplies water to two-point-four million homes. The system´s pipes and tunnels cross three major earthquake faults. An upgrade could prevent the aqueducts from collapsing in a major earthquake and leaving several Bay Area cities without their main source of water.
