My original estimate, ON which the
amount of the bond issue was deter
mined, provided for wood stave pipe,
and covered practically miles OF
8 inch supply main to guard against
the possible necessity of going out to
the northwest some distance for the
source of supply. This we now ex-
pect and hope win not be necessary.
The lengths of pipe called for in the
bids were consequently reduced in
proportion, and were as follows:
inch, 1850 feet; inch. $4,000
feet; s inch, $3.50 feet
Based upon these lengths, the
relative costs of wood stave, wrought
iron and cast iron piping system
complete, laid In the trenches and
back filled, lis as follows:
Wood stave Pipe
1850 feet 4 inch at 33 cts. per
foot, $1,OO6.5O
$1,000 feet inch at A cts per
foot, $6,6O0.OO
$3.50 feet inch at SO cts. per
foot, $3,923.5O. Total $11 $4,000.
Matheson Joint Wrought Iron Pipe
1850 feet inch at AIS cts. pei
foot, $1,44S75
$1,000 feet 6 inch at 63S cts pei
foot, $4,000
$3.50 feet inch at 92.45 cts pei
foot, $6,147.93. Total, $17, 1868.
Cast Iron Pipe.
1850 feet 4 inch at 69.9 cents pei
foot, $2,131.95
$4,000 feet inch at 96.7 cents pen
foot, $14,505.OO
1856 feet inch at $1.S2 per foot
l$8,778OO. Total $25,41495
From the foregoing table, lit lis to b
seen that, based ON the same lengths
in each case, the cost of Mathesor
Joint wrought iron pipe lis 4S pei
cent greater and cast iron pipe 100 pc
cent greater than wood stave pipe
To INSTALL a complete system within
the amount OF the bond issue, witt
we'll, water tower tank and pump
ing machinery, and laying the above
lengths Of pipe, 1t would be impos
sible to use either Matheson john
wrought iron pipe or cast iron pipe
II they were used the length of pipint
would have to be reduced, about q
per cent in the case OF the Mathesor
Joint wrought iron pipe and about
so per cent In the case of cast iron
pipe.
The question of the probable life
Of the three kinds of pipe and the
probable annual maintenance and re.
pair charges wa.s then taken into
consideration. 1t is my opinion
when the quality Of material and
workmanship i'm each case is the
best In the market and the pipe is
properly laid under skilled and ex.
perenced supervision, that the rela.
tive life Of the three kinds of pipe
under physical conditions such as
those existing at Mountain Home,
may be safely taken as follows:
Wood Stave, 80 to 40 years.
Wrought iron, about so years.
Cast iron, 100 years and over.
The annual depreciation therefore,
would be about as follows
Wood stave, 2 1-2 to 3 2-3 per cent.
Wrought iron, about / 2-3 per cent.
Cast iron, l per cent or less.
To provide for such depreciation,
an annual amount is set aside from the
gross receipts as asinking fund, af-.
ter the system has been ian operation
for five years. This sinking fund will
draw interest and the annual amounts
set aside therefor would be figured
SO that enough would have accumu-
lated to entirely replace the piping
at the end of its usefulness.
The matter of annual maintenance
and repair charges is a more difficult
one to exactly determine in advance
but l should not expect to find these
charges vary much on the average
the following.
Wood stave, $4,000
Wrought iron, $4,000
