If the owner of any building desires to install a private fire protection system in a manner complying with the rules of the fire underwriters, to be used only in case of fire, the Service Department will lay a pipe from the main to the curb and place a valve and a valve box at the curb at the expense of the owner of the premises. No fire service shall be installed which has a carrying capacity of more than fifty percent (50%) of the carrying capacity of the water main to which it is connected. A swing check valve must be placed in the line between the valve that is installed by the Service Department and the sprinkler heads, hose connections, or hydrants to prevent water backing into the system. Water for fire purposes shall be free. In cases deemed necessary by the Service Director, the owner or occupant of the premises shall install a meter and pay regular meter rates for all water used, except in case of fire. It shall be a condition of the grant of such supply that the owner or occupant of the premises so supplied shall maintain the system free of leakage or improper operation, and shall prevent the unauthorized destruction of the seals thereon, except for the control of water discharge arising from the replacement of sprinkler heads or pipe breakage. In every case, the destruction of the seals shall be immediately reported to the Service Director. (Ord. 2011-59. Passed 8-9-11.)
