through wooden hume around The set
ting tanks, This course was taken to
Keep the water from interfering with
the wor at the intake. The dam will
remain in place until after tho pipe line
is completed. Then il will be removed
aud the channel of City creek viii be
through R tn, the iron pipe line, sa EISePs {So
viii be little water flowing through the
creek below the intake. What water
remains in the old channel will he that
which comes from springs below the in
take and from -seepsgc.
High Altitude.
The intake of The high line is lust
1000 feet in altitude higher than salt
Lake at tho city and county building.
With this grade the water will attain
au eighty pound pressure at it's mouth
at Thirteenth avenue and j street. From
this point the water will be distributed
throughout the city mains and will IN
crease tho water supply throughout the
city. The new high line will be of eS-
pecial value to the residents of the
north bench. Al present the water pres
sure is scarcely enough TO supply them
with water. However. when the new
high line is completed The pressure will
he ample 10 care for all the residents
of Tho foothills. while the supply will
be sufficient 10 care for a city of 100000
population
From the second settling tank Il
grade almost uniform has been cstah
lished all the way down the canyon TO
the mouth of the pipe line. This
grade has ncccssitated a vust amount
of excavation. At some points the cuts
are as deep as twenty-five feet. Some
gullies are crossed by the pipe line.
and over these the pipe passes on con.
crete piers, which will be covered
with Garth to prevent freezing.
The excavation for the pipe line was
one of the hardest portions of the work.
1t was necessary to complete this, If
crew Of almost 800 men has been
doing the excavation work for the past
thirty days, with the result that this
portion of the work is now about CON
pleted, What excavation has not been
finished viii have been completed by
the last Of the week There was little
loose dirt, For the most part the lino
runs through loose rock formation,
and in some eases the bouders are
so large as to require blasting, In sew.
eral eases beds of solid rock and rhyo-
lite impede the excavation. These OBJ
structions will be removed by blasting.
Course of Line,
The pipe line will run along he
| north side of the stream from the IN
take to the natural bridge near the
foot Of the canyon. There it will he
taken across the creek in concrete
arch. The line will be elevated
tri6e on the mountains on the south
side and then viii descend to the
point Of distribution at Thirteenth
avenue and J street.
About $50 feet of pipe already is
laid. Each section of the heavy cast
iron pipe weighs little more than
ono ton. The entire line will take
about 1900 tons of pipe. and will be
1900 feet in length. Each section is
lowered by means of block and
tackle, from the roadway above the
| line 10 the ditch BY means of
hoist it is then lowered onto a little
| truck, which operates on a sectional
railway track along the bottom of the
ditch. On this miniature tram the
pipe Is taken to the point whore it is
to be Joined to the sections already in
place. There the hoist brings the sec
tion into place. The joint is then
soldered while another section is being
lowered into place.
Placating Weather Man.
If the good weather continues a
fortnight all the eycayatiug will have
been completed aud a j the concrete
work finished. After that is done cold
weather will not impede the work to
any great extent, The only possibility
of the work bciug stopped is IN the
event Of big snowstorm, which might
stop the traffic in the canyon. With
ordinary good luck Mr.. Moran expects
TO have the contract entirely completed
and the. first water flowing through the
| new pipe line by the middle of
February. Under the contract he has
until June | to complete the work.
The new line which is being built
will probably replace the :wclye-iuch
pipe line now in use. The old line has
its intake mile and half below the
intake Of the new line. The former fol
lows the contour of the country, and
much pressure is lost by the varying
grade. The old line was laid in 1890
and while the pipe is still good, IL is
corroded considerably from lime and
| its capacity is small Gt is probable
that the old line will be taken up next
year,
To Feed Reservoir.
! Another feature of the new line is
that it may be used 10 feed reservoir,
which may be built whenever the needs
of the city warrant, on the reservoir
site near the entrance to City Creek
CANYON. There is room there for Il
reservoir which will hold forty million
gallons of water. However, at present
the water is ample for the city, In
time the reservoir will probably be
needed The city officials are making
plans for reservoir at some future
Time which will hold the night flow
from the pipe line and distribute it
through the mains for day use, thus
oualizing the water supply during the
day and the night. Later it may be
feasible to store large amount Of
water in the proposed reservoir,
IN any event the new highlino has
solved for years the problem Of pure,
fresh water for Salt Lake, and the
wonderful progress toward the compile
ton Of the great undertaking is CRAFTY.
