REPORT OF THE COMMITTEE ON WATERS. 
Present and Prospective Use of Water for the Development of 
Power in the Hawaiian Islands. 
Honolulu, Hawaii, -Nov. 14th, 1908. 
In considering the conservation of the resources of this Terri- 
tory the possibility of the development and utilization of water 
power should be given very serious consideration. 
At the present time a few developments have been made which 
are of considerable economic value and there are great possibilities 
for future development. At the present time practically all the 
water power is in use generating electric power to supply motive 
power for irrigating pumps, the most important one being the 
Kauai Electric Company on the island of Kauai, where two twelve 
hundred kilowatt generators are installed in Wainiha Valley, 
utilizing some forty million gallons per day at ji head of 575 feet. 
Power is transmitted 35 miles to the McBryde Sugar Company's 
plantation and there utilized in operating six multiple-stage centri- 
fugal pumps direct connected to motors of an aggregate horse- 
power of 4,000. These pumps have a capacity of 31,000,000 gal- 
lons at a head of 175 to 400 feet, thus serving to irrigate over 
3,000 acres of cane. 
At Kekaha, Kauai, water is taken from a high level irrigating 
ditch and dropped 275 feet to irrigate the low level lands. At 
this point a six hundred kilowatt generator is installed to furnish 
power for four motors direct connected to multiple-stage cen- 
trifugal pumps having an aggregate horsepower of 700, the pumps 
having a capacity of 7,000,000 gallons at a head of 300 feet. The 
water for these pumps is taken from an irrigating ditch and 
pumped to a level above the ditch, thus rendering 700 acres of 
good cane land available. 
The Pioneer Mill Company, at Lahaina, Maui, has installed a 
250 kilowatt generator operated by water power which furnishes 
current for 200 horsepower motor operating a triplex reciprocat- 
ing pump, which delivers 9,000,000 gallons of water against a 
head of 100 feet. 
The Oahu Sugar Company, on the Island of Oahu, take water 
from an irrigating pipe line and develops 120 kilowatts, which 
supplies a 100 horsepower motor direct connected to a centrifugal 
pump. 
The Makee Sugar Company, at Kealia, Kauai, has installed and 
in operation a 300 kilowatt generator supplying current to a 225 
horsepower motor operating a reciprocating pump having a capac- 
ity of 2,800,000 gallons of water against a head of 250 feet. 
The Waianae Sugar Company, on the island of Oahu, has in- 
stalled two 200 kilowatt generators supplying current to motors 
of 375 horsepower to pump six and a half million gallons of water 
against a head of 150 to 280 feet.
