New We'll About Completed
Says City Engineer
STARTS GOOD RECORD
Better Flow Than Others That
Have Been Sunk BY the
Municipality
From fridays Daily.

The new city well, located at the
corner of Second and Spring streets,
and to be known as the Spring street
well, which is the deepest, best con-
structed and largest flowing well in
the city. is now completed. Work of
piping this well and drilling it ceased
Wednesday and the finishing touches
hav enow been put on it.
This well is ,451 feet deep, or
eighty-six feet deeper than the Nc
Carthy well, heretofore the deepest in
the city. Its flow is 700 gallons
minute, or fifty gallons more than
that of the Mccarthy well when the
latter was new. 1t cost the city 49,
500. The contractor was Matt Hol-
land of Cannon Falls, who has done
well work for the Hubbard Milling
company. His work is considered
very satisfactory. 1t took him months
to get the well down until it tapped
a lower stream of water than any
other well in the city or probably in
the Minnesota valley.
Ten Inches in Diameter.
The well is ten inches in dame
ter its entire depth, and is piped 161
feet down. The city adopted new
system of piping for this well, in
the hope that the expensive work of
repiping every eight or ten years
might be done away with, and it is
believed that the piping will not have
to be replaced in fifty years. There
is an outside wrought iron casing,
sixteen inches in diameter, going
down seventy eight feet, and inside
of this there is a cast iron casing
fhic 6nnfh
the we'll was bored out with a diam
eter of fifteen inches. The space
between the outer pipe and the rock
wall below and the inner pipe, the
entire 161 feet, is filled in solidly with
cement, and it is not thought that
leak will be possible. This is the
first well in the city to have a cast
iron casing, and this casing has heavy
brass couplings. Ordinary wrought
iron pipe is eaten up by the chemi-
cal elements in the city water in
from six to ten years, but it is be-
lieved that the harder cast iron will
stand this corroding effect much bet
ter. The cost is somewhat greater.
but it is thought that the money is
well spent.
Price of the Well.
winnie UTlS wen Is lOWeT lHdl any |
other in the city, it is thought that |
the water coming from it is no hard
er than that from the other wells,
although tests have not yet been
made.
Mr. Hollands contract price for |
putting down the well was $3.50 a
foot, and the casing is extra. Mr.. |
Holland will remain in the city for
some time longer as he has the con-
tract to lower one of the Hubbard |!
Milling company's wells and will go i
at this work at once.
The flow of the city wells is now |
estimated at 1,400 gallons per min |
ute. There are three city wells in
use, the two older now having a |
diminished flow and together yield
ing only as much water as the new !
well. One of the city wells practi- |
cally gave out some time ago and |
was plugged up. The city is pump
ing about 100000 gallons a day |
now, so it will be seen that it now |
has an abundance of water, the flow |
now being about 100000 gallons a
day.
The recent hot dry spell did not |
cause the use of much more than the
normal amount of water, except the
few days preceding the shower.
There are now over LOO private |
taps, and these use lot of water all
the time The citys water system !
is getting to be large and import
ant business in itself.
