flew IL replace depletion in use. Sup
ply mains to service distribution sys-
tenn to be in duplicate.
wB.") Gravity flow from sufi-
GENTLY elevated reservoir to which
the supply is delivered by duplicate
sets of hydraulic or steam power
pumping engines, drafting from a
source of constant supply. The re-
Servoir to be Of sufficient capacity to
hold in store six to ten ,.ays' reserve
supply equal to the average service
for all purposes. The combined capa-
city of the pumping engines should be
equal to the delivery Of the total
average per diem supply Of the town
within ten hours, and one-half Of the
pumping capacity should accomplish
the same result within twenty hours
of continuous operation. Supply
mains to serve distribution system to
be in duplicate.
WC.") Gravity flow from COM
bined and connected high and low
service reservoirs, the water supply
from same being secured by any OF
the methods indicated under "A' or
"B": supply mains to the distrlbu-
tion service to be in duplicate. High
and low pressure service to be pro-
perlv connected 50 as to permit high
service pressure in low pressure dis
tribution in case Of fire or other en-
ergency.
WD.') Direct pressure service by
means of duplicate sets Of hydraulic
or steam power pumping engines, sup
plemented by an auxiliary reservoir
or stand-pipe, having independent
supply mains to tbe distribution sys-
tenn and also duplicate supply mains
from the pumping station to the dis
tribution, provided with proper
checks against the reservoid or stand
pipe in order to permit high pumping
service III LuG N1SG1
WE.") Direct pressure service by
means Of duplicate sets of hydraulic
or steam power pumping engines,
without the use Of an auxiliary reser-
voir or stand-pipe. Supply mans
from the pumping station to the SER
vice distribution to be in duplicate
and to be provided with proper relief
and other safety device to prevent ae-
cident.
wF.") Gravity flow from sufi-
ciently elevated reservoir to which
the supply is delivered by duplicate
sets of pumping engines actuated by
gas or gasoline engines operating on
the explosion principle. In all other
respects to conform with the condi-
tiops under class "B."
Note-The following systems are
permitted only when conditions are
such as to warrant approval by the
Inspection Department, which should
be consulted in each specific case:
("G.'') Public fire eisterns hav-
ing capacity from 10000 to $4,000
gallons each, filled from flowing wat
er, natural springs or some other re-
liable source, properly located and
in sufficient number to afford the pro-
lection demanded.
wH.') Water supply from per-
manent ponds Or flowing streams ac-
cessible to engine suctions and con-
tiguous to congested districts OF
buildings or values wherever located
in town.
The Pipe Scheme, when served as
outlined in any Of the systems of wat
er supply classified from "A' to
"E" inclusive, should include dupll-
cate mains from the source of supply
to the distribution system, each OF
such mains to be Of sufficient capacity
to fully supply the service under the
full average requirements of combln-
ed domestic and fire-defense con-
sumption.
The system Of distribution should
be divided into sections by properly
located gate-valves, and the so-called
"grid-iron" system should prevail,
particularly in the built-up sections
and the congested value districts. No
main intended for use in the fire sell
vice of less diameter than SIX in
ehes to be allowed in the residential
or the minor retail sections, and none
less than eight inches in diameter IN
the business, manufacturing or other
congested districts; the sub-mains
supplying the borders of the "grld-
iron' system to be not less than 10
or - inches in diameter. dead
