Surface Water

ouA0SC VoSCA
The only other available supply is
that of the Sheyenne River. This is
undoubtedly ample if properly i'm
pounded, is probably the softest avail
able and, therefore, best for use in
boilers and laundries. Because it is
surface water and because it flows
through a well-settled rural region
and the city, this water is unavoid-
ably polluted to such an extent as to
render it unfit for city use without
chemical treatment to destroy the
harmful bacteria which it contains
and to. render it safe water from
the sanitary standpoint. This would
be constant overhead charge, and is
not desirable if wholesome water pure
from the sanitary andpoint can be
secured.
Conclusion
Study of the general geological and
drainage conditions leads to the very
definite conclusion that by far the
most satisfactory source of water sup
, ply for Valley City is the alluvial gra-
I wells, the source now in use.
Analyses by the State Public Health
| Laboratory show the water taken
from the present we'll to be satisfac-
tory and so long as this is true no
other location need be sought. The
amount of water moving down. valley
through the thick beds of sand and
gravel beneath the valley floor is so
great that contamination of the pres
ent we'll is not anticipated provided
the city enforce reasonable sanitary
/ laws in the vicinity Of the plant.
1t is, therefore, barring moderate
amount of mineral matter in solution,
pure and wholesome and the best
available supply. The supply is ade-
quate for all probable needs Of Valley
, City. The only question involved is
, the method Of securing enough water
I to meet the rapidly increasing de-
/ mands of the city.
! Recommen da tons
Since the suction limit has practi-
! cally been reached in the present we'll,
it is necessary either % to secure a
larger flow into this we'll, or (2) to
put the pumps lower to lower the sue
ton limit, or 90 to use some other
method for the recovery of the water.
1t is, therefore, recommended:
| /. That a 10 or IL inch pipe be
sunk in the bottom of the present
/ we'll, fitted with an or 8 foot John
son strainer of the maximum dame
ter capable of being inserted in the
pipe, and with slots not less than So
1000 of an inch in width. The bottom
; of the strainer should be set practi-
cally on bedrock shale, at most not
more than one foot above the shale.
The increase due to freedom of flow
through this pipe may be sufficient to
supply the city for some time.
g. In case the supply in the we'll
is not sufficient for all demands con-
meet the pump to the large pipe and
pump direct.
3. If there results any tendency
under most severe tests to break va
CUM, convert the present well into a
concrete pump pit, put the pump down
to point where it is kept "primed,"
that is below the normal water level
Eventually, in my opinion, this will
be necessary. The yield under these
circumstances should be over one-half
million gallons daily. Additional
yields can be secured at any time by
the installation of other wells in the
immediate vicinity of the plant. These
new wells should not be placed nearer
than 100 feet to one another.
Finally, I have no hesitation in say
ing that Valley City has an ample
supply of good water for all the needs
which it is now possible to anticipate.
Respectfully submitted,
Howard E. Simpson,
Ground Water Geologist.
