WATER SUPPLY FOR FIRE PROTECTION
The PACNAVFACENGCOM Fire Protection Engineer has the responsibility for
establishing fire flow requirements at various locations at Navy shore
facilities. Based on fire flow demands, station water storage
requirements are established. Since fire flow demands are usually
greater than domestic or industrial demands, the fire flows normally
govern the design bf water supply systems which must accommodate fire
flows plus a certain percentage of the average domestic requirements
and industrial or flushing demands that cannot be restricted during
fires. The accomplishment of design projects for water supply systems
must include the close review of the PACNAVFACENGCOM Fire Protection
Engineer. Station master development plans shall include adequate
water supplies for future fire protection demands which will be
established by the PACNAVFACENGCOM Fire Protection Engineer. Fire flow
demands and water storage requirements shall comply with MIL-HDBK-1008A,
Fire Protection for Facilities Engineering, Design, And Construction
(most current edition). A close surveillance of station water supplies
for fire protection will be maintained on a periodic basis with serious
deficiencies brought to Command attention for possible correction.
A reliable and adequate supply is required for fire department hose
streams and automatic sprinklers. In order to determine the adequacy
of a water supply, it is essential that the A-E provide-the following
information at the site of the project during the development of the
35% Design.
a : Static water pressure with no flow from fire hydrants.
b.
Flow in CPM or pitot tube reading from 1 - 2-l/2" hydrant
outlet.
Residual water pressure with 1 - 2-l/2" hydrant outlet flowing.
c.
d. Flow in GPM or pitot tube reading from 2 - 2-l/2" hydrant
outlets.
e. Residual water pressure with 2 - 2-l/2" hydrant outlets
flowing.
f.
Size of water main supplying hydrants.
Hydrant identification numbers.
g.
h.
Time and date of test(s).
i. Location of hydrants in relation to nearest buildings(s).
