would be about $500. 900. The lower
end OF this canal would then be about
100 feet above the elevation Of The
river opposite. or approximately an
elevation Of $500. The elevation OF
Sunset Heights reservoir is 1920 feet
Practically all the water now used
by the city OF FL Paso IS pumped
from the mesa wells 10 these reser-
voirs and from these reservoirs a
booster plant raises part OF the water
20 the Crazy Cat reservoir. On the
mesa another booster plant serves
the highlands northwest OF the pump
ing plant. The present capacity Of
the storage reservoirs serving the
city OF FL Paso is entirely inadequate.
considering the present size Of the
city and its probable rapid future
growth.
Cost Of Pumping.
The present cost Of pumping Is
nearly 6 cents per 1900 gallons, which
cost does not include interest, depre-
citation, or overhead The cost to the
city Of FL Paso during the year 1920,
assuming a population Of $4,000 and
an average yearly consumption per
capita per day Of $50 gallons, would
be about S365,000, aud for the year
1925, S625,O00.
IT the supply for e. Paso were
carried fin an extension Of the lower
high line canal so as to deliver water
into a reservoir near the city at an
elevation Of approximately $500 and
properly designed pumping and boost
er plants operated by electricity we're
built the cost OF pumping, including
power labor depreciation and re-
pairs, assuming power could be pur-
chased for 1 cent per kiloWatt hour,
would be about as follows:

or a saving for 1920 OF S283,0QQ, and
for 1925 OF 100000.
With proper reservoir capacity Il
would not be necessary 10 operate
any Of the pumps during the peak
demand for power and hence the low
est rates could be secured.

-Four Factors In Saving.
The great saving In the cost Of
pumping operations is due to four
'-F'irst-The lift would be less.
Second-The efficiency OF pump
ing operations would be far higher.
since all the water is now pumped
from wells by air lift pumps. which
require about three times as much
power as high class centrifugal
pumps.
''Third-The labor cost would be
much less.
''Fourth-The cost Of power would
be less.
This saving in cost Of pumping
would continue 70 increase as the
population OF the city increases.
There would also be the additional
advantage OF a certain and ample
water supply for the city. If the en-
TIRE valley becomes so thickly settled
as TO endanger the supply. water
could be brought TO FL Paso from
Elephant Butte dam in a closed con-
duit
The city OF Los Angeles had a nop-
ulation OF about 200.O 900 when. Ia 1898.

more than three times as great.
There should be constructed AZ the
lower end OF the proposed suupiy
canal a reservoir Of the largest Ca
pacity that topographic conditions
VIII permit. Storage in this reservoir
would permit sedimentatiou TO take
place and, II considered necessary at
any time, the water pumped from
this reservoir could be treated by
some OF the well known. modern
methods.
