THE CONDUIT
10 the terminal chamber, distance OF four
and half miles. The conduit is 51ax6 feet,
and has running capacity of &c. 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 a 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.
HOW BUILT.
From the gate chamber the conduit runs
southerly one mile, crossing the Duluth road
at point !, ,105 feet east of the town corner
of sections 1, 6, 81 and 36. From there it
runs southerly for mile and quarter pass
feet OF the conduit are laid through 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 Fhalen
creek for mile and quarter. Passing
through Little Canada it was found neces-
sary to excavate to the depth of thirty-fve
feet, caused by q cut of 600 feet long
Beyond this it runs through a swamp
for 800 feet, where the conduit is
laid on bed of concrete supported by piles.
The line then runs through tunnel passing
through hill, 300 feet in length. The next
half mile is in very wet bottom, and concrete
was again used A quarter of mile of ex-
| tremely hard bottom follows, which is in turn
followed by a half mile of good bottom, on
| the west shore of Sandy lake. Below the
! lake the conduit crosses a creek on 200 feet
of stone masonry. The remainder of the
| conduit rests on hard clay bottom, and in
about 1900 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 McCarrons g lake.
1t will be handsome brick structure 45x30
| feet, with a 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 thirty-inch pipe
will be used to convey the water from the
| terminal chamber to the low service reser-
voir, while a 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 capacity of 10000 and
| 1,500, 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 100 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
mile and half to the high service reser-
voir, which is to supply Anthony hill. This
line Of pipe leaves the pumping staSon 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 to the reservoir, and the
other being detected to the left and run ming
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 an
other line of pipes runs to the high service
reservoir, located on the top of the hill 900
! 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
100000. Until it 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 1t into the line of pipes extending to
st. Anthony's hill. The country is so rough
that it is impossible to conuect the high SER
vice main with Dayton's bluff. When Seventh
street is graded, a 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-fye feet above st.
Anthony's hill.
THE Low SERVICE SYSTEM.
The low service system will be constructed
few hundred feet southeast of the terminal
chamber, and will be connected by the latter
with two 30-inch pipes, through which the
water viii 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 30inch 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 ~ at present.

COST OF THE PIPES.
The cast iron pipes through which the
water flows are manufactured by Sickle, Har-
