Report on Water Works System


driving by individuals has demonstra-
ted the existence of ground water
supplies in the vicinity of the town
where it is proposed to install a
water works system so that in most
cases there Is AN assurance that a
satisfactory supply can be found with.
in certain limits.
In this particular case feel reason
ably assured that no great difficulty
will be encountered in locating a sat
isfactory source of supply by means
of deep wells within a reasonable dis
lance of the corporate limits of the
town, If not actually within the same.
| Not only do wells already driven at
| Mountain Home indicate this but also
the general slope of the ground to-
ward the south the water sheds to
| the north and northwest and the UNI
dergTound flows which have been
found at several places to the north
all indicate the probability of the ex-
istence of a large body of ground
water, The slope of the water table
of this under ground supply, is unr
doubtedly from the north to south.
The depth to which deep we'll
would have to be driven in order to
tap pure and adequate supply of
water free from fine running sand,
can be determined only by actual
driving of the we'll.
The main elements which enter in
to the design of the piping system
through which water is to be distnb-
uted, are the pressure and capacity
required for fire protection and the
distributing capacity required for or
binary daily domestic consumption
will be regulated by these elements.
In towns the size of Mountain Home,
and situated as this town is, ON
very level ground, the generally &C
cepted method in the best water works
practice is to design the size of the
distribution piping for a capacity suf-
ficient to supply population of from
5000 to 10000 inhabitants under an
average daily static pressure of from
40 lbs. to so lbs. per square inch
The storage required at the instala-
ton of such a system would pro-
badly have to be increased long be-
fore the supplying capacity of the dis
trdbution piping is reached. The stor
age provided will be drawn upon
much faster from May until October
than it will be during the balance of
the year. To offset this, however,
the pumping machinery will be oper
ated for a shorter period per week
from October until May than during
the balance of the season.
To secure the pressure and quantit
OF water required for fire protection.
the pumping machinery is generally
arranged for pumping directly into tn
distribution piLir2 IN such emergen-
cies thus reinforcing the stsorage
tank or If necessary. cutting it out
Of service for the greater pressure.
For adequate protection in case of
fire the system should be able to
deliver sufficient water for two full
fire stream undel a pressure of
about 80 lbs. per square inch. To
secure this without direct pumping
would call for larger mains, greater
storage capacity and higher ele
Walton for the stored water, all of
which would make the cost of the
system excessive. The modern and
better provision for fire protection
is that stated above, /. e. an elias
tic pumping service.
Taking all of these matters into
account ii is my opinion that lead
lUS HAIL o lIlCueS III uldm6leT, w.
900 gallon tank 10 #. high and pump
iLg machinery designed to deliver
from $50 gallons to 500 gallons, per
minute with pressure of at least
so lbs. per square inch will be suf
ficient and satisfactory for the town
of Mountain Home, and adequate to
supply a population much larger than
the present with all the water re-
quired for domestic use and fire pro-
tection.
The system as prcpcrcd covers
about 1850 TT. of inch /, $50 #. of
