Emergency Firefighting Water System
Following an earthquake, the San Francisco Emergency Firefighting Water System is vital for protecting against the loss of life, as well as the loss of homes and businesses by providing an additional layer of fire protection. The system is also used throughout the year for the suppression of multiple-alarm fires. The system delivers water at high pressure and includes two pump stations, two storage tanks, one reservoir, and approximately 135 miles of pipes. The system includes 52 suction connections along the northeastern waterfront, which allow fire engines to pump water from San Francisco Bay, and two fireboats that supply seawater by pumping into any of the five manifolds connected to pipes.
