The M1ddlebury Aqueduct.

Gentlemen: The scheme is to take the
water from the brook Gin the Little
Notch Bristol at the down stream
point examined. but the profile is made
from the point above, and, of course.
shows a few hundred feet too much dis
lance
1t is proposed to use (for the S-inch
main SYSTEM l0-inch pipe for a dis
lance of 300 feet from the intake. From
the end of the l0.inch pipe to station 1872.
near the small cemetery south Of Crows
house. an S-inch pipe of the standard
thickness for 300 feet head; the balance
of the S-inch pipe to be heavier, to suit
the increased head to the terminus at the
park in Main street.
The 6-inch. 4-inch. and 3.lnch pipes are
estimated for the greatest head or pres
sure.
On the village map the blue lines indi-
cate S-inch. the red lines G-inch. the
brown lines l-inch, the green lines, 3-inch.
For the G-inch main pipe, an estimate
of which is also sent, the arrangement of
pipes in the village and of hydrdnts and
valves is the same as for the S-inch main,
except in the size for a few valves.
For this scheme (thc siX-inch main)
an estimate is made for 300 feet of S-inch
ton 1872. suitable for 300 feet head. and a
heavier pipe for the balance.
The difference in cost of the G-inch and
the S-inch mains is so considerable that
| have thought it best to send an esti-
mate for both.
And | will say that the 6-inch main
will supply all the water thai Middle
bury will be likely to want within the
next 100 years: and, with the great head.
the hydrants will be very efficient. In
fact, the head is too great both for ny
drants and for service faucets. and the
pressure should be reduced in the main
at the point where il reaches the village.
The following table will Illustrate the
capacity of both schemes:
SINGH MAIN.
Velocity of discharge per second SOC feet
Discharge per second, 80 gallons
diem, s29,440 gallons
Pressure per square inch at Addi-
son House, 49, pounds
near bridge, ljl pounds
GINCH MAIN.
Velocity of discharge per second, 3,3l feet
Discharge per second, 4,5s gallons
diem, 39j,9l2 gallons
Pressure, substantially as above.
For the S-inch main, assuming that the
water will be drawing during lG
hours only of the 24 each day,we have a
daily supply of $4,000 gallons.
Allowing 30 gallons per capita (Which
is the maXimum), we have a supply for
population of | | 900.
In the case of the G-inch main. assum-
ing as above. we have supply for a
population Of j.2OO.
1t is perfectly safe to say that the
G-inch main will give you water fortwice
your present population and provide for
all other wants. including considerable
amount of motive power.
In view of this. ! recommend siX-inch
main. | am aware that communities
after a dry season feel very thirsty, and
not infrequenlly do they 90 to needless
extreme in this matter. 1t is common
remark, Let us build large enough
while we are about it" and parties in
terested in furnishing water supplies al
ways encourage the use of large pipes
But enough is enough, and money spent
in providing more is wasted.
Until seven years ago all the water
that supplied the village of Rutland raj
through four-inch pipe.
This, however, is for Middlebury tC
decide. ! merely give my opinion. Il
should be borne in mind that the grea
head reduces the necessity for a large
pipe.
1t will be observed that estimate tho
pipe at one and half cents per pound
r. ID. Wood a Co.. of Philadelphia. yer,
extensive makers of pipe and builders o
aqueducts, write me that it will be tri
file less than ! - cents delivered in Troy
! am of the opinion that 3S cent
would buy it.
(Here follow estimates of freightng
ditching. etc.
The details of the other portion of tn
estimates need not be specified in thi
place. Finally, | have added per cent
to cover contingencies. | have made tn
estimates more fully in detail than wa
perhaps necessary, but it occurred to IN
that you would like to see all of the items
l have estimated for no pipe less tina
inches. Nearly Onc-half of the 3-inc
might be reduced to 2-inch.
! have provided for valves to insure
good circulating system and as many ny
drants "a double hydrants and p singl
hydrants) as seemed necessary.
All prices of iron work are based o
actual offers. Hence | feel confideI
that they are safe.
(Here follows an explanation of I'll
elaborate maps furnished by Mr.. Ran
dall.) In conclusion Mr.. Randall give
long detailed estimate of all the item
of construction. For the S-inch mai
the entire expense including the p,
cent for contingencies is S57.75S.00; IL
the 6-inch main, S4j,730.SG. To til
should be added the land damages fC
the right of laying the pipe through IL
fields and the damage to riparian owner
This estimate does not include the e.
pense of service pipes, which is usual
borne in whole or in part by the taker
