Mains


Cd That the distribution system be strength
ened by the installation of such mains are
necessary to furnish fire supply as follows
tag In the principal mercantile district
$3.50 gallons minute.
thl In closely built residential districts 1000
to 1000 gallons minute.
tc) In outlying residential districts 500 to
/ 1000 gallons minute.
! The above quantities to be in excess of do
nestle consumption and to be available in the
| high value districts about any large building or
group of buildings Of special hazard, and in
4 the mercantile and residential districts about
any block.
I Where direct hydrant streams are to be used.
I the above quantities are TO be available at a
1 residual pressure Of at least rs pounds in the
high value district: in closely built residential
districts so pounds and 30 pounds in thinly
built sections Of low height Where engine
streams are to be used, the above quantities are
to be available at residual pressure of 20
pounds.
(2i That the following be adopted as the
standard minimum sizes Of mains used for hy-
drant supply for all future construction.
(al In residential districts s-ineh 6-inch 20
be used only where they complete a good grid
iron and in in blocks 500 feet or more
in length
tbi In mercantile and manufacturing dis
tricts. s-inch and 12-inch, the former TO be-
used only in sections wnere they complete a
good gridiron and the latter for Ions lines not
cross-connected.
(Sl That well-dehned plan be adopted
whereby all 4-inch mains used for hydrant sup
plN Will be replaced WltNiN reasonable nfrlohp
dead ends eliminated Wherever practicable.
large mains cross-connected 10 distributors at
frequent intervals and long stretches of pipe
eross-conneeted so that generally not more than
one hydrant viii be on 6-inch main between
intcrsecting lines and not more than two hy-
drants s-inch in closely built and con-
gested districts
Note-The exchange believes that il is es-
sentialy the business Of each municipality TO
lay out its system of distribution mains as it is
best able to judge Of present and future con-
sumption in each district and of other local
conditions involving paving, topography. press
ures size and type of hydrants, etc, but prae-
tical experience has shown that the abovs
quantities arc required for coed fire protection
in districts such as arc found in this city and
that the gridiron system of mains of the sizes
above is satisfactory only when
dead ends and with large secondary cross-feed-
er mains az frequent intervals.
Gate Valves.
(si That the distribution system be equipped
With 4 sufficient number of gate valves SO lo-
ated that no single case Of accident hreakage
IT repair TO the pipe system in the high value
districts will necessitate shutting of from
eryfce a length Of pipe greater than 500 feet.
II greater than 500 feet in other sections. and
yil not result in the shutting down ct an
rtery.
Hydranis.
Isl That additional hydrsnts be installed in
ccordanee with the following;
"a In the mercantile and manufacturing dis
rfctE the average nncaF spacing not 70 eNcee1
90 feet and the average area served per hy-
rant not to exceed 81. 600 square feet II engine
treau1s are used and $4,000 square feet Tor d.

ian 2is pounds in the hydrant and total loss
not more than pounds between the street
