thousands gallons per minute will
supply from eight to ten hose
streams.
me distribution system in the
business district of Rawlins must
be such as to deliver around any
business block eight to ten hose
streams and maintain the pressure
OF so pounds per square inch at all
the MOBILES. In the residence por-
ton of the city, 1000 gallons per
minute plus all consumption is suf-
~ficient.
AS the distribution system is now
constructed there can be delivered
around my business district in Raw
Inns only $50 gallons per minute at
65 pounds residual pressure, and
1850 gallons per minute with SO,
pounds residual pressure. On the
south side of Adams street between
Center and Water streets there can
be delivered only $40 gallons per
minute with the residual pressure OF
rs pounds per square inch. At First
street, between Spruce and Pine
streets the system would deliver only
1872 gallons per minute with a res
idual pressure of so pounds per
square inch.
Plenty Of Reserve Water
I With the Sage Greek System there
will always be held in reserve pract-
icaliy $500. 900 gallons, with water
being diverted at the rate of practic-
ally 1000 gallons per minute to the
new reservoir. Consequently there
can be no question about there being
available 1000 gallons per minute
plus normal consumption for 10
hours. The normal consumption, in
Guiding the Union Pacific Railroad is
taken at the rate Of $500. 900 gal
Ions per "a hours. or at the rate of
1900 gal. per minute Consequently
the distribution system must deliver
water at the rate of $500 gallons per
minute and maintain a pressure of
so pounds per square inch. The
supply line from Sage Creek will de-
liver, at the intersection of Lincoln
Highway and Fourth street 1915 gal
Ions per minute. AS soon as the
pressure begins dropping below 81
pounds per square inch then the 10
inch line to the present 500, 900 gal
lon reservoir will begin delivering to
the down town section. When the
, pressure falls to 60 pounds per square
inch, the present reservoir will de-
liver around any business block sup
piled by it, and the proposed extern
sion. 1875 gallons per minute. Thus,
+ by balancing the pressures by reser-
voirs located at opposite ends of the
mains. so water will in case Of heavy
demand flow both ways to the sec
> ton creating the demand, there can
be delivered around the business sec
I ton of Rawlins 1850 gallons Of wa
t ter per minute. This is all that
I Gould possibly be desired.
t Additional Hydrants
t There is a demand for some addi-
tional fire MIGRANTS. The Fire I'm
t derwriters require in the business
district n hydrant for each two
acres Of ground. Rawlins has a
fire hydrant for each three acres Of
e ground. Consequently. there should
: De installed one more hydrant for
each two O installed. These
hydrants can be placed o nthe new ex-
e tensions. In the residence district
n The Underwriters require one hydrant
o TO each two and one-half acres. Raw
g lins has one hydrant. in the resi-
8 dence district. to each ten acres.
}. consequently for each hydrant now
$ Installed in the residence district
8 there should be installed four ad-
y ditional hydrants.
S At the present time the addition of
e so hydrants in the city will amply
d meet the needs Of the Underwriters,
K With a distribution system such a.
3 here proposed the reduction In in.
re jsurance rates will average 10 per
n cent in the business and residence
districts.
- In the recommendations there
e have been made much more extended
improvements in the distribution sys-
d tenn than specified by the Underwrit-
ers. but 1t IL desired t place Rawlius
in the IN or 3 classification with
much greater reduction In fire in
surance rates than specified above.
This. OF course, cannot be done BY
a water system alone but requires a
coordination OF all departments Of
the city government.
l. The following amounts of pipe will
be required in order to make the
proper extensions within the city
limits:
$3.50 lin. It. 12-in. C. I. pipe.
$ $3.50 lin. IT. 10-in. c. l. pipe.
$500 lin. IT. Sin. c.. I. pipe.
Wood Stave Pipe
Wood stave pipe has been in use
. over 0 years. 1t has presented 4
varied history. Wood pipe has been
e used in Philadelphia from 100 to
: 125 years and still in good coDdi-
. ton. OF course conditions were
a ideal.
1t has been only within the last
five years that wood pipe has. come
o to its proper place in the construc-
tion of pipe lines. 1t has been
through the use Of creosote and az
E phalt that wood pipe has been made
