fire hydrant

High pressure fire hydrant (San Francisco)

Thiose hydrants are part of the AWSS, the San Francisco Fire Department "Auxiliary Water Supply System", developed after the big 1906 Fire.­ The AWSS is separate from the drinking water supply of the city, and if needed, it can be fed by sea water from the bay.­
