mize in the cost of the building as fal
as practicable, and fortunately its sit
uation is such that no ornamentation
in order to make it in keeping with the
surroundings, will be required. The
boiler room will have no inside finish
whatever, and have an earth floor. The
pump room will have wooden floor OF
two thicknesses of matched pine floor.
ing, and matched pine ceiling with
oil finish. The walls will be unfinished
leaving wainscoting and plastering fol-
some future time when there may be
more money available for the purpose.
Iestimate the pump house as above
described, without the iron stack and
including foundations for pump, to
cost 81 1875.
PUMPING PLANT.
There should be one boiler about 81
inches in diameter and IA feet long,
and rated at about 60 horse power. 1t
would be desirable to have two boilers
of this size, but for the amount of mon
ey at your disposal only one can be af-
forded; the additional boiler can be
added at some future time. One boil
er can be safely depended upon for
the service required, if intelligent care
and skill is exercised in the operation
of the plant.
The pump should be duplex pump
of the simplest kind, non-compound,
non-condensing, and of about l,OOO,-
600 gallons capacity at ordinary speed
In emergencies, this capacity could be
increased somewhat if required. The
pump should be of size and power
enough to not only raise the water tc
the elevated tower, but in addition tc
maintain a fire pressure of not less than
70 pounds per square inch on the n.y.
drants in the business portion of the
city. It should be connected with the
pump we'll and also with the mill POND
or river, so that the supply may be
drawn from either source as required
A pumping plant such as above out
lined, together with feed pump, feed
water heater, and all connections and
fittings, set up ready for use, including
also an iron smoke stack, will cos
$3.50.
The ideal water tower would consis
of a wrought iron or steel tank upon 1
tower of the same material set upo1
stone foundations. There is, however
not money available for such struct
ure and it is necessary to build
wooden tank and tower. The tanl
should be similar to those in common
use throughout the country by the rail
roads, except that it will be raised mucl
higher above the ground, being set up
on a wooden tower of such height tina
the bottom of the tank will not be less
than IS feet above the surface of the
ground. At very little expense in the
way of cornices, finishings, painting
and the like, this structure may b'
made to present much more slightly
and pleasing appearance than thu
common railroad water tank.
The use of wooden tank and tow
er is less Objectionable than may a
first appear; as the pumping plant vii
be removed from the tower there viii
be little danger of the structure being
destroyed by fire; the universal exper
fence of the railroads has been that
where these tanks have been properly
built and cared for,they are long-lived
The tank should last twelve to fifteel
years. The wooden tower will not be
as durable, but properly designed
should last ten years, and repairs cal
be made at any time by taking GU
such timbers as need to be replaced
without interfering with the use of thu
structure for but a few hours at th'
most. The inlet pipe leading into the
tank will be cased in such manner a.
will afford complete protection agains
frost: frost will not interfere with the
use of the tank. The most desirable
site for water tower is, as nearly a:
practicable, in the center of the pipe
system. It is seldom, however, tina
suitably elevated and accessible
ground for such as structure is founc
where most desired. l advise that thu
water tower be placed near the cross
ing of Mill street and the w. & St. P
R'y; the ground at this point is high
er than anywhere else within reason
able distance of the city, and the ]oca
ton is adjacent to the main line O
pipe from the pump house to town
The ground occupied by this structure
will be about As feet square. A near
or site to the business portion of the
town would be desirable because Of
the less friction loss in the mains, due
to the length of pipe, but in this cast
it is probable that the loss in elevation
in any available site, would more thar
offset the advantage. The hydrant
pressure on I'd street, from tower o.
this height and in the location men
toned would be 48 pounds per square
inch if the tank is full. This tower
should be provided with all automatic
valve so arranged that when tank il
full, valve in the supply pipe will bt
closed and signal given at the en-
CINE house to stop pumping. The wa
ter tower could at any time be shut
off from the rest of the pipe system, SO
as to allow of direct pumping if desir
able. I estimate the water tower al
above described to cost $500. Al
iron or steel tower of the same height
surmounted by the same size woode1
tank would cost about $500 more.
RIGHT OF WAY.
have made no estimate of the cos
of the right of way and land required
in the construction of these works, TO
the reason that you are prepared to as
certain the value of such privileges a
may be required. 1t does not seen
likely that this item can amount t.
