One or more on-site sources, such as wells or open bodies of
water, with treated water storage capacity adequate to supply
domestic demand for 24 hours plus the maximum required fire flow
demand.
For a small, non-mission-essential activity, such as a reserve
training center, a single connection to a looped or gridded public
water distribution system, capable of providing concurrent domestic
and fire flow demands to the facility, is acceptable.
3-5.1
On-Site Storage.
Where on-site storage is part of a sole-source water supply, or is needed to
provide the required fire flow, the storage facilities must be divided into two or
more approximately equal capacity tanks or reservoir sections, arranged so that
at least one-half of the water supply will always be available during tank or
reservoir maintenance. The discharge or suction line(s) from each individual
tank or reservoir section shall be sized to deliver the maximum required fire flow.
Exception: Existing water storage facilities deemed reliable by the AHJ may be
acceptable.
3-5.2
Monitoring
Water level must be remotely monitored in accordance with NFPA 22 and NFPA
72 at a constantly attended location, preferably at the installation's fire and
security dispatch center. In locales subject to freezing, water temperature of
above-ground storage tanks must likewise be monitored at a constantly-attended
location.
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 fire rated room in accordance with NFPA 20 and must have
direct access from the exterior.
3-6.1.2
For mission critical facilities, provide a reserve fire pump of the
same size when the water supply cannot support 25% of the sprinklers in the
hydraulically most remote design area with the primary fire pump out-of-service.
