Pumping Plants.
Five pumping plants are so situated as to
supply all canes planted below the $50 foot
level. These pumps, working night and day,
throw the water into system of sixteen
reservoirs, where all surplus water is stored
The respective capacity of the different
pumping stations are FIVE, ten, seven,
twenty-five and twenty.four million gallons
in "a hours, giving a combined capacity of
$4,000 900 gallons. The pumps which are OF
the Reidler, Fraser & Chalmers and Risdon
Iron Works types, all derive their steam
power from fuel oil, which is a thirty per
cent. saving in labor and material over coal.
Some of these pumps are of the triple ex'
pansion type and others are compound. The
pumps force the water through steel pipes,
from 20 to 80 inches in diameter and 200
to 1000 feet in length to a varying elevation
of so to $50 feet The wells are from 240 to
$40 feet deep and often pass through streams
of surface water
When more mountain waters are devel-
oped and larger areas of land are placed un.
der cane cultivation, 1t is contemplated to
drive the mill machinery, pumps machine
shops, with electrical power.
The Kaukonahua Poamoho, Helemano,
ply the plantation with mountain water for
irrigation purposes. These streams are all
permanent but during the dry seasons the
flow is limited. Hence the pumps. The
bitches leading from these streams are so ar.
ranged that during a food the largest pos
sible amount of water is conveyed to the
reservoirs where II remains available for
future use.
,.yttl it,aI
city of 100000 gallons are so situated
that they may be filled during dry weather
by the pumps or when possible from the
streams. One large reservoir having ca
pacity of 14O,OO000O gallons, located at the
1000 foot elevation and can be filled from
the stream only. Cane planted upon the
high lands is irrigated from this reservoir
The expense OF pumping to such an eleva
ton would be prohibitive.
A few flowing artesian wells supply some
water to the lands lying below the 12-foot
level. None of these wells flow at higher
elevation than twelve feet above the sea
level.
About 14Oe men are employed upon the
irrigation system at Waialua during the sum.
mer months, one man taking care of seven
to ten acres of land. During the rainy sea.
at time in some instances.
Thirty miles OF main bitches convey water
from the streams and reservoirs to the cane
fields, where "a veritable maze of smaller
bitches cover the whole plantation. Much
tunneling was resorted to in conveying water
from the gulches, there being twenty miles
of tunnels. Tunneling In the mountains for
new sources of water was tried but without
success.
The opaeula dam, at an elevation of 1000
feet, which forms a large reservoir with a
capacity of 14O,0OO,O0O gallons is 80 feet
wide at the base, 20 feet wide at the top and
holds water to a depth of 60 feet This
earth dam, designated and built by L. f
Tannatt, A. A. Wilson. being the contractor
is 10 feet high, the greatest height Of an
earth dam in this Territory.
Large steel inverted syphon pipes, the only
ones of the kind upon Oahu, carry the water
across deep gulches.
