for, or waste. In the United State:
it varies from approximately so gal
Ions per capita to 400 gallons pei
} capita per day. In towns where the
service is metered it is usually under
100 gallons per capita, but industrial
draft. which has little bearing or
population. may in a small town in
crease that rate very materially.
Domestic use covers household
service and lawn sprinkling. These
may, and very often do, involve vol
umes of water going to waste through
defective plumbing and fixtures; from
open taps, in the summer time to
keep vegetables fresh, and in the
winter to keep unprotected pipes
from freezing; and in unnecessary
and wasteful application to lawns ::
which, in the aggregate. is easily the
major portion of the supply. Rea-
sonable economy in the use of water
can only be effected by the use of
meters, but much unnecessary waste
can be eliminated by action of the
proper city officials.
Public use includes sewer flushing,
street sprinkling, drinking fountains
and troughs, schools and public build
ings, and fire protection. Schools are
quite often very extravagant users.
Fire service may make big draft
for a few hours at long intervals. but
in volume it represents a compara-
lively small portion of the per capita
consumption. A fair rate for these

Ions per capita.
Commercial consumption is more
uniform in its relation to population.
and usually ranges from 10 to 90 gal
Ions per. capita.
Unaccounted for water covers that
which is lost through leaks and from
broken mains, and is often very
serious drain on the supply. Expert
ence indicates that it may range from
Is to so per cent of the total supply
Per capita consumption is the re-
suit of the average total daily con-
sumption for the year divided by the
population. The maximum monthly
rate of consumption may be from 10
to 80 per cent higher than the aver
age for the year. Further. there will
be weeks and there will be days when
the consumption will exceed the aver
age for the maximum month. The
range in rate is usually from 90 gal
Ions to so galolns per capita, above
or below the average.
Outline of Plans
After careful study of the water
supply, and the situation generally,
| tri
ing reservoir of a capacity of from
,250. 900 gallons to 100000 gallons
was essential to the satisfactory and
efficient operation of the system. The
minimum rate of flow of the available
supply. of water is too small to meet
the maximum drafts without med
ium of equalization. 1t was natural
to look towards the Garnet reservoirs,
| but their location in relation to the
sources of supply is unfavorable. The
supply pipe leading to them is too
small for the full utilization of their
capacity. The great cost OF suppli-
menting the pipe capacity, together
with the work necessary to bring the
reservoirs into sound state of repair
is a most serious obstacle to these
reservoirs becoming an equalizing and
distributing link in the water system.
recommend the construction of a
reservoir at or in the vicinity of the
pressure tank on Orchard Mesa; the
division of the town into two service
zones, dividing the water therefor at
First street and Meeker avenue,
where controlling valve will protect
the lower zone from the effects OF
high pressures; and, further, l ad-
wise the carrying out of repairs and
improvements to put the system in a
condition to deliver water to the city
on the basis of population of 1000,
and maximum consumption of 1926
gallons per capita per day. This is
not an unusually high rate for Colo
RADIO, and Western towns generally.
1t is rate, however, that can be in
course of time, by careful administra-
tion, and the reduction of waste to a
minimum, materially reduced.
| The following governing data are
recommended: Estimated minimum
supply Of Dough Spoon and Dirty
George creeks, 2.O4 C. (. g.; and mini
mum capacity of the lines from the
pressure tank to the city, 2.s5 C. I. g.,
equal to 1,275 gallons per minute.
Capacity Of System
The estimated minimum supply of
water is 2.04 c. I. 8. This flow, with
out an equalizing medium, would fan
short of meeting the fluctuating daily
demands, and the draft usually al
lowed for fire extinguishing purposes.
The amount of water required for fire
fighting may be said to be the con-
trolling factor in adjusting capacity.
That is to say, capacity which will
