Replenishment of Storage. The water storage must be self-
replenishing. It must reach required volume during normal consumption within
48 hours, and within 24 hours curtailing normal consumption.
3-5
SOURCES OF WATER SUPPLY.
3-5.1
Primary Water Supplies. Primary water supplies must consist of
one or a combination of the following:
Two separate connections to a public water system (one
connection is ample for a small activity, such as a Reserve Training
Facility) that when one connection isolated, water can still be
supplied to the activity.
Elevated tanks or reservoirs.
Multiple pumps with adequate suction supply.
3-5.2
Secondary Water Supplies. Where public water supply is
inadequate or unreliable, a secondary supply is required. Secondary supply
must be by gravity tank, pressure tank, booster pumps taking suction from
adequate capacity main(s), or fire pumps taking suction from adequate source(s).
3-5.3
On-Site Storage. Where the on-site storage is the sole source for
the water supply, the storage must be divided into two approximately equal
capacity tanks or reservoir sections, arranged so that at least one-half of the
water supply will always be available during tank/reservoir maintenance. The
discharge or suction line from each tank or reservoir section must be sized to
deliver the maximum required fire flow.
Exception: Existing warehouses where the existing water storage
facilities are deemed reliable by the AHJ.
3-6
FIRE PUMPS.
3-6.1
Requirements. Pumps for fire protection must have adequate
capacity with reliable power and water supply. This equipment must conform to
requirements of NFPA 20, Standard for the Installation of Stationary Pumps for
Fire Protection. Fire pumps, drivers, and other equipment including automatic
accessories must be listed by UL, approved by FM, or listed or classified by an
NRTL.
3-6.1.1
Fire pumps must be located in a detached, noncombustible pump
house or located in a 2-hour fire rated room with direct access from the exterior.
