distribution system should be sufficient to meet these
conditions:
a)
Instantaneous peak domestic and industrial flows
combined
b)
Maximum fire demands, plus 50 percent of average
domestic demands, plus industrial demands which cannot be
restricted during the fire

hours of average demand after a fire.
2.3.5
Reservoirs. Reservoir capacity should be adequate to
satisfy the total of the following requirements:
a)
Peak fire flow demand as given in MIL -HDBK-1008C.
b)
50 percent of average daily consumption (domestic
and industrial).
c)
