You will note from the above that
the great bulk of the expenditures for
permanent improvements have been in
developing, transporting and conserv.
ing water for irrigation. AS the life
Of the plantation depends upon its
water supply, and as the cost of oper.
ating the plantation Is largely increas
ed or decreased by the methods used
in distributing the water over the
fields, for irrigation. the following in.
formation in regard to the water de.
velopment at Waialua should be Of
material interest to you:
There are 10 Compound and Triple
Expansion Pumps In five pumping sta.
tions, and one at the mill, with a total
pumping capacity of 72,000.OO0 gal.
Ions of water every "a hours. and am.
pie water to run said pumps at full
capacity If necessary.
Also three Gasoline Engine Pump.
ing Stations. Capacity 5000, 900 gallons
every 81 hours.

ing water from the smaller bitches, and
from the pumping stations at night
There are two larger reservoirs. with
u total capacity of about 100000. 900
gallons. which are supplied with
water from three gulches, namely Opae
ula, Kawaiild and Waimea. These
guches depend for water upon the
rainfall in the mountains, and records
show that the rainfall at the heads OF
the first two gulches mentioned aver.
ages from 60 to so inches per year
There Is a record of one year showing
a rainfall OF l51.46 inches, at the mead
Of Kawaiki.
A large dam IL Just nearing compile.
tion at Waialua which will hold the
water from two large gulches which
pdjoin each other, at a short distance
from the dam. There is a larger and
steadier flow OF water here than from
any other stream in the island OF Oahu
draining large watershed OF several
thousand acres OF the summit and
slopes Of the Koolau mountains.
The dam Is to have a capacity of 2,
10000 900 gallons. There are two 9th
e. streams of fresh water coming from
two other gulches, containing larger
streams and draining larger water
sheds than the Opaeula and Waimea
streams which up to the present time
have been practically untouched. Il
is intended to make use Of this at q
later date.
With the water development above
outlined, as coming from the gulches
and conserved by the dam and va
rious reservoirs, 1t Is believed that
about $4,000 acres Of land. all below
the 7O0'foot level can be irrigated by
these mountain streams, the greater
part OF every year; and It is possible
that when the streams have been fur

thereby producing large crops on the
upper lands.
Above the 900-foot level, 1t Is esti
mated that from four to six thousand
acres OF good land can be cultivated
with cane, large part of which land
is comparatively level, with soil OF
good depth and quality. The rainfall
on these upper lands ranges from Il
to go inches per annum, as shown by
records, which Is about the same rain
fall as in ordinary years Is found In
Hamakua, Hawaii; Kau, Hawaii, ant
Lauhala, Hawaii. And 1t is probable
that from these upper non-irrigateC
fields, the cane will yield from three
to four tons of sugar per acre.
The money expended on this watel
development proves to be most wis'
expenditure, and for the best interest,
