wells as temporary source OF supply. it.
! would be best to first put down one we'll
of diameterof about IS feet and about
40 feet, deep. The we'll should not be
| located in the immediate vicinity Of any
, dwellings and had best be located just
west Of the. depression on the west side
of the city.
We estimate the cost of a shallow we'll
as above described at 81 600.
Deepwells. Some time ago the rail-
way company sank a awell to a depth of
about 1,1oo feet and record of this we'll
furnished us by the railway company
shows that water similar to that obtained
at Medora can be obtained from various
sand rock layers within depth of about
$50 feet. The we'll put down by the
railway company was of small diameter
and no proper test of the capacity of the
we'll was made, so that it is difficult to
say definitely how much water could be
secured from this source. We believe,
however, that we'll 10 feet in diameter
at the surface and reducing to 8 feet in
diameter at the bottom would give an
ample supply to meet your requirements
for many years.
Water in the railway we'll at Dickin-
son did not flow to the surface as at
Medora, as the surface at Dickinson is
about I4o feet higher than at Medora.
The water in the railway we'll stood at a
level of about 20 feet below the surface,
and in order to draw the we'll down
enough to get sufficient supply, it
would be necessary to use some form of
deep we'll pump.
The we'll could be located at the most
convenient point and the cost of putting
in long supply pipe, such as would be
required if a supply is taken from the
river, would be avoided.
| We estimate the cost of we'll 10 feet
in diameter at the top and reduced to
8 feet at the bottom and $50 feet deep at
$3.50.
| Heart River Supply. The railway
company at present takes its supply
from the Heart river and is using about
100000 gallons per day which is in ex-
cess of the flow of the river during a
portion of the year. In order, therefore,
to have sufficient supply at all times, it
has been necessary to construct dam
in order to afford storage to carry them
over the dry periods. The dam of the
railway company is located below the
center of the city, and as there is con.
siderable surface drainage from the city
into the river above the dam, it would
not be safe to use the water from the
railway company's reservoir without
fltering, and in any event the present
; reservoir of the railway company is only
sufficient to supply the present needs o1
the company. In order to take supply
from the river, therefore, it would be
necessary to construct new dam al
some point far enough up the river to be
above the surface drainage from the city
and this would necessitate going to some
point above the brick plant.
There is no suitable location on the
, river near the city for the construction o.
a large reservoir at a low cost, as the
, height of dam constructed within the
banks of the river would be limited te
about feet. We estimate that a dam o.
this height would create reservoir witt
a storage capacity of about twelve mil
lion G2,ooo,ooo) gallons, which would be
! sufficient to supply your present need:
without seriously interfering with the
railway company's supply, but as the
domestic consumption increases, it woulc
be necessary to secure increased storage
capacity. In order to meet the ultimate
needs of both the city and the railway
company, we think it would be necessary
to ultimately provide a storage capacity
of not less than sixty million (6o,ooo,ooo
gallons. This could be done by con
structing additional dams further up the
river and permitting the water from tht
81 Iupper4reservoirs to flow into the lower
j one as needed, or by the construction O
/; single large dam. extending above anc
] beyond the immediate banks of the rive
: and raising the water high enough tt
, overflow the low lands adjacent to The
! river. AS the city and the railway com
!, pany would be equally interested and a:
! the construction of single large dan
or series of small dams would involve
] a large expenditure, the final worl
5 should only be undertaken by the city
r and railway company jointly, but it j:
E not likely that the railway compan,
E would be willing to cooperate at the
+ present time as they consider their pres
: ent supply sufficient.
Il If, therefore, you decide upon river
supply, we think that for the present the
best thing to do would be to construct
