A. All tanks, cisterns or reservoirs maintained for fire purposes shall be metered at the expense of the Owners of the Premises or parties supplied.
B. Where a riser is installed in a building to provide fire protection through hoses in racks, the supply of water must come from the metered line and be connected on the outlet side of the meter.
C. In cases where it is not feasible to take the riser from the metered line, such as the height of the building, etc., it may, with the approval of the Division of Water Distribution, be taken from the fire system on the outlet side of the fire pumps; however, a monthly charge will be made for each hose rack opening, equal to that charged for each private fire hydrant on a fire system.
D. All jockey pumps used to maintain pressure on an un-metered fire main shall be supplied from a metered source.
