THE BRANCH WATER SUPPLY.
Engineer Cairns Reports to the Com
mittee with Regard to Cost, Size of
Pipe, etc.
Mayor Webster presided at the meet
ing of the committee on additional
water supply last evening and there
were present John Fitzpatrick, III. L
Wade, F. B. Rice, M. j. DAILY, T. d.
Barlow, Q. Hauser, FL. Hart, T. L. San
ford, City Attorney Burpee and City
Engineer Cairns. The object OF the
meeting was to adopt site for a storage
reservoir and to determine the size of
the conduit pipe to be used. City Engi.
neer Cairns, who has given the subject
so much time and attention, and who
has made practical demonstrations as he
advances, offered the following report:
To the Committee on an Additional
Water Supply:
| beg leave to report as follows:
list. The work of stripping the ledge
at the proposed site of the dam, hereto
fore referred to as site No 8, has pro-.
crossed far enough to indicate a sub
stantial and satisfactory foundation. /,
therefore, recommend that your honor
able body accept this site as the one
upon which the proposed dam b.
erected.
Sd. In regard to the dimensions of the
dam, would respectfully invite your
attention to the following facts devel
oped by our surveys: A dam whose
height above the present bed of the
brook shall be 65 feet, raising the water
to a height of 60 feet above the bed of
the brook, or to a height of 265 feet
above the water table of Irving block,
will flow an area of about SO acres and
!, 1 nrrfxY0 ilah 10 okA Tn
} of about $50 millions of gallons. Such
: a dam is estimated to cost about $50, 000
A dam whose height above the bed
of the brook shall be eighty feet, raising
the water to height of rs feet above
J the bed of the brook, or to a height OF
$50 feet above the water table of Irving
: block. will flow an area of about 105
capacity of about 600 millions of gal
Ions. Such dam is estimated to cost
about $110,000.O0.
In connection with this dam it will be
necessary to construct an earth dam
across the valley south of the ridge,
which is estimated to cost about $780,
t 900. 90.
In view of the immense advantages in
, pressure and available storage attaching
TO the higher dam above mentioned,
slI would unhesitatingly recon.
mend its adoption: 1t is proper
to note, however, that we are now
> taking much broader views of the flu
ture needs of the city than have been
: taken heretofore, and are proposing
, much greater expenditures than have
been up to the time deemed necessary
r fore, to advocate strongly a larger
: policy in the matter, l would suggest to
the committee the following plan, viz:
That we build a dam to the height oil
] 65 feet above the bed of the brook, as
Q above mentioned, but that il be pro.
? portioned throughout for height of sc
. feet above the bed of the brook. We
: can then avoid the expense of the earth
dam at the present time, and use the
4 valley across which it will ultimately be
built for an overfow.or spillway.
On this plan it is estimated that the
dam will cost $95, 900.
3rd. / would respectfully ask the
committee to determine the size of the
pipe to be used in the main leading from
9 the reservoir to the city.
D The length of the main pipe here will
( be nearly II miles long, the exact length
: not being yet settled, pending further
!. study of the best location. The dis
7 lance proposed is from the reservoir tt
0 the southeast corner of center square
8 A main composed throughout of 80 inch
a pipe would deliver 100000 of gallons
Q Iper day, and the reservoir as above pro
o posed, under the conditions obtaining Of
: a large use during the day and small
D Iuse during the night, and withou
Q Iserious dimunition of pressure. figur,
that the pressure would not fall below
leo pounds with flow above. Under
fsimilar conditions line composed of 81
inch pipe would deliver about 1900, 0O(
Iof gallons. The SO inch main woulC
Icost about SIC, 900 per mile more thar
Q the 80 inch pipe.
81 Respectfully submitted,
r. A. CAIRNS.
VI June %, 1898.
ih The recommendation of the engineer
las regards a site was adopted. Tht
+ Iquestion of the size of the pipe was de
n Ibated at much length and the commit
q tee finally voted to adopt 80 inch pipe
The members believe, however, that i
would be a good investment to have {
IS6-inch-pipe, but it would cost abou
$4,000 more to have it, and they d.
3 not feel at liberty to incur such add
J. tional expense. A committee was ap
Is pointed to prepare statement of til,
lcommittee's views in the matter ant
4 Isetting forth that they would adopt
4 36-inch pipe If the council would agret
to pay the bills. A bid from the War
rem Foundry of Philadelphia to suppl,
= four miles of pipe of the required size a
y $3.50 per ton was adopted. Telephone
. connections between the city and tn
works on the Branch were ordered t
!, be made at cost of $3.50. A bid from
It the Waterbury Steam & Gas Pipe work
l. to supply 100 horse power boiler TO
500 was accepted. The city attorne,
was instructed to take steps to procur
the Mrs Hotchkiss property.
