able. Pumping station No. In Hama
pepe gulch is supplied with Worth
ington triple expansion pumping plant,
and will lift 100000 gallons of water
to height of $50 feet in twenty -four
hours. Steam for the pump is develop.
ed by Sterling water tube boilers. Wa.
ter here is developed party from
bored wells, water tunnels reaching to.
wards the bluffs and river, also means
Wy which the water can be taken from
the bed OF the river to the main pump.
The main tunnel towards the mountain
is 1000 feet long and the tunnel to-
wards the river is SO feet long. Work
upon this latter tunnel was stopped
owing to the great body Of water en-.
countered. until such time as the new
stump at the pump can be completed,
and section pipes put In place. 80 as to
enable the main pump to take care Of
the supply. This system Of water will
be complete within months time.
Water from Hanapepe.
Pumping station No. 8 also located In
Hanapepe gulch consists Of a Risdon
high duty pump Of 100000 gallons
capacity, lifting the water $50 feet.
Steam Is generated with three Heine
boilers and supplied with the Green
fuel economizers. Water for the sys-
TEN is obtained from wells, surface
tunnels and water rights from Hama.
pepe river. The main surface tunnel
at this station, which is 175 feet in
length. has been stopped for the same
reason that exists at station No. 1.
The main water supply coming from
the Wahiawa river at an altitude OF
1900 feet, is conducted through tun-
mel 1860 feet in length, having ca
pacity of 30,000,000 gallons in twenty
four hours, and discharging into reser-
voirs four in number already con-
structed. No. reservoir has a capa-
city Of lis 1000, 900 gallons; No. 3 reser.
voir, 7s,000,600 gallons; No. 4,
Sc, 100000 gallons; No. s, 100000 gal
Ions: No. 2, 11S,000,000 gallons (now
under construction). There are also
two small reservoirs that take the
night and day water from pumping sta
lions Nos. and already constructed
having a capacity Of 1850, 900 gallons
each. The water for this reservoir
connects with the same bitches that the
pumps discharge into at their several
lifts or elevations, which permits OF
continuous irrigation from reservoir.
or pumps. All the reservoirs are con.
nected with each other so that water
can be drawn from any one Of the
reservoirs to the main supply ditch.
The main bitches leading down from
the reservoirs to the ditch system
which is supplied by the pumping sys-
tens are two feet deep and five feet
wide, having fall of $50 feet in mile
and a half. The main distributing
bitches have a fall of FIVE feet to the
mile, having a normal carrying capa-
city of 25,OOO,0O0 gallons In twenty
four hours. In conveying water across
gulches. inverted syphons have been
laid. using 33-inch double riveted stee!
pipe hNNt supply 10 iiotii
laval and Kalaheo streams. This
water is intercepted in its course by q
concrete diverting dam now being con-
structed, and conveyed through often
two and a half miles in length having
q maximum capacity of 25,OOO,OoO gal
Ions In twenty-four hours, and convey
ing the water to the West laval cane
fields extending clear across the Kawa-
iahaka gulch. A new reservoir Is now
being constructed In West laval for
the purpose OF storing the food wa
tiers from the laval ditch system,
which has capacity for storing u.s.
10000 gallons.
Contemplated improvements.
The improvements contemplated in
the still further development Of water
will consist CT an extension Of the
reservoir system by the construction of
one large reservoir about one-half mile
below reservoir No. In Kawaiahaka
gulch. The dam to retain this water
will be rs feet in height, while the es-
timated capacity will be 100000, 900
gallons. Numerous reservoir sites In
the East laval fields are available
above the $50 foot level for storing s.
100000 gallons Of water which will be
filled from the flood waters of the La
wall stream, and utilized for irrigatiEs
the East laval lands. The conditions
are highly favorable for the develop
ment of water by tunnels In the noun
tains at nominal expense, which would
In all probability double the normal
Cow Of 100000 gallons per day In
the Wahiawa stream. The laval and
Kalaheo streams have normal flow
of 100000 gallons per day at the head
Of laval ditch. This normal flow,
however. Is at a dry time of the year.
On the old Koloa lands now part Of
the McBryde plantation. reservoirs
have been constructed having a capa-
city for storing 25,0O0,000 gallons and
Is supplied through ditch system
from the laval stream and from the
local water sheds. This water is to
irrigate the cane fields now planted
on the Koloa lands.
In laval gulch wells where the new
Reidler 100000 gallon pump is being
erected, the percentage OF salt In the
water is only nine grains to a U. s.
standard gallon. Mr.. Miller, the en-
gineer Of the McBryde plantation, Is
now preparing complete map Of the
property which will show in detail the
water bitches, storage reservoirs, rail-
