There are apparently some rather unsettling findings about San Francisco's firefighting capabilities. 

The great quake and fire of 1906 destroyed most of San Francisco.

Now, the San Francisco Chronicle reports the city's emergency water system is not adequate for putting out multiple fires at once, as could happen after a big quake.

The paper reports that city voters have approved millions of dollars in bond money for an elaborate emergency water system, but that the city has failed to spend it properly.

Retired Assistant Deputy Fire Chief Thomas Doudiet says the city has an endless supply of water, but an inadequate emergency delivery system.

Doudiet says half of the city could be left without water for firefighting in a major disaster.
