Passing through the gate house the water is
conveyed In
i THE CONDUIT
To the terminal chamber, a distance OF four
| and half miles. The conduit is 81 x6 feet,
and has running capacity of 30, 900, 900
| gallons daily. 1t is built of two layers OF
brick, with an outer shell of rubble stone.
and the whole is buried beneath four feet OF
earth. Portions Of the conduit are laid upon
the earth, this being found practicable where
there is dry, hard clay bottom. Where
there is wet bottom, not deeper than four
or five feet concrete is used, and where the
depth exceeds this piles are built, the con-
crete bottom being placed on them and the
conduit built upon the concrete. At some
places it was found necessary to lay piles to
the depth of forty feet.
ROW BUILT.
From the gate chamber the conduit runs
southerly one mile, crossing the Duluth road
at point | ,105 feet cast of the town corner
OF sections l, 6, 81 and 36. From there it
runs southerly for mile and quarter pass
ing through Little Canada. The first 5000
feet OF the conduit are laid through q swamp,
and rests upon concrete bottom. The con-
duit passes under the Duluth railroad in a
tunnel twenty feet beneath the surface,
Leaving Little Canada the line follows Phalen
creek for mile and quarter. Passing
through Little Canada it was found neces-
sary to excavate to the depth of thirty-fiye
feet, caused by q cut of GOO feet long
Beyond this it runs through a swamp
| for 500 feet, where the conduit is
| laid on bed of concrete supported by piles.
The line then runs through tunnel passing
through hill, 800 feet in length. The next
| half mile is in very wet bottom, and concrete
was again used A quarter of mile Of cx-
| tremely hard bottom follows, which is in turn
| followed by half mile of good bottom, on
| the west shore of Sandy lake. Below the
lake the conduit crosses creek on 200 feet
| of stone masonry. The remainder of the
conduit rests on a hard clay bottom, and in
about 800 feet reaches
| THE TERMINAL CHAMBER.
| The terminal chamber will be located at a
point about 800 feet south of Sandy lake,
and little distance east of McCarron's lake.
1t will be a handsome brick structure 45X30
| feet, with stone basement. Passing
| through the gates out of the conduit the
water will enter chamber 12x23 feet, from
where it will be carried by pipes into the low
service reservoir, or to the pumping station.
| The conduit is built to furnish 500, 900 peo-
| pie with water, and the terminal chamber
was planned for the same purpose, there
being room for six pipes leading to the res
ervoirs. For the present a thirtNinch pipe
will be used to convey the water from the
| terminal chamber to the low service reser-
voir, while twenty-six inch pipe will lead
| to the
| PUMPING STATION.
The pumping station will be located about
| 1000 feet east of Lake McCarron, and about
| two miles north of Como avenue. The
building will be 45x39 feet. of brick and
stone masonry, with concrete bottom. The
pumping room will contain two Reynolds
pumps with a capacity of 100000 and
1,5O0, 600 gallons per day respectively. There
| is also room for two more pumps, which will
| be added when needed. In the boiler will
be located two boilers, capacity 120 horse
| power each, and room has also been made
| for two addition al boilers when needed
THE HIGH SERVICE SYSTEM.
The water will be forced through twenty
four inch pipe from the pumping station for
a mile and half to the high service reser-
voir, which is to supply Anthony hill. This
line of pipe leaves the pumping station and
runs along the south shore of McCarron IS
lake. About 1000 feet before reaching the
reservoir the pipe ends in Y, one line con-
tinuing from the Y to the reservoir, and the
other being DETECTED to the left and running
southeast to Dale street. Thence it runs
south on Dale street to Como avenue, cross
| ing the railroad to Western, and up Western
to Summit, where it is distributed over the
! hill by smaller pipes. Leaving the Y an
other line of pipes runs to the high service
reservoir, located on the top of the hill 600
feet east of the residence of Mr.. Blake, and
one and half miles northeast of Lake
Como.
HIGH SERVICE RESERVOIR.
This ground is nearly 100 feet higher
than st. Anthony's hill, and the water will
flow by its own gravity to the highest point
on the hill. The reservoir will cost about
S200,000 Until 1t is completed the water
will be forced by the pumps through the line
of pipe laid along the south shore of McCar-
ron's lake to the Y where water gate will
throw itinto the line of pipes extending to
st. Anthony's hill. The country is so rough
| thatit Is impossible to conuect the high ser.
vice main with Daytons bluff. When Seventh
| street is graded, small pumping station
will be erected on Seventh street, which will
| tap the present line from Lake Phalen The
high service reservoir will be 80 feet above
the river level and eighty-fve feet above st.
Anthony's hill.
THE Low SERVICE SYSTEM.
The low service system will be instructed
a few hundred feet southeast Of the terminal
chamber, and will be connected by the latter
with two 30-inch pipes, through which the
water will flow by its own gravity. This res
ervoir will cost about s150,000. Until this
reservoir is constructed the citizens of the
lower portion OF the city will be furnished
with water direct from the conduit From
the terminal chamber a line of 30-inch pipe
will run southeast about two miles to Mis-
sissippi street, and continue on Mississippi
to Broadway. The line is continued down
Broadway to Seventh street, with a 24-inch
pipe, where it connects with the present sys-
TEN of pipes, and the water will be distribu-
ted as at present.
The Pipe System.
COST OF THE PIPES.
The cast iron pipes through which the
water flows are manufactured by Sickle, Har-
