The Hawaiian star. [volume] (Honolulu [Oahu]) 1893-1912, 1901-07-15

On the east side of Laval gulch there
| are to be built two reservoirs later on
for the Koolau land The water sup
ply for the Laval system comes from
the Laval and Kalaheo water sheds
The Koloa land is further protected
from lack of water by a big reservoir
of about 100000 600 gallons capacity in
the Aipo gulCh and in addition there
are more reservoir sites selected. The
Koolau stream is also the source of
considerable water supply Reservoirs
for the storage of storm water in La
wal and Kalaheo gulches will also be
constructed although the pumping sta
ton at Laval is expected to handle
considerable of the freshet supply.
Excellent as is the reservoir system
on the east side of the plantation the
big system for the storage of waters is
located about the central part of the
place the reservoirs being from 600 to
700 feet above sea level. There is a
chain of five in number. The largest
which is now completed has a capacity
of $4,000, 900 gallons; a second can hold
75,O0OOO0 gallonsfli a third lis, 100000
gallons. Two others are being built
which will hold about 6S,000,000 and 15.-
100000 gallons respectively. This system
of reservoirs gets its chief supply from
the Wahawa stream. A tunnel of 800
feet i'm length taps the stream and in
addition there are four large bitches
which convey the water from this
stream to the reservoirs. Two bitches
also catch the water lower down the
stream 50 that there is no chance of any
sunpv going to waste
In the construction of this system of
reservoirs particular attention has
been paid to preventing every chance of
their overlooking or breaking their
banks. In case No. 1 should become
too heavily charged there is natural
outlet to No. 8 and from this reservoir
is tunnel connecting with No. q Con-
neCtion is also made with the other re-
servolrs. In addition to these there are
number of smaller reservoirs
of 100000 gallons capacity lower down
on the plantation as well as other re-
SerVOirs for storing night water. The
water from this system is taken across
the Wahiawa kula by two large
bitches. Farther connection has also
been made with the Laval side of the
plantation in order to save the storm
supply. There is a vast stream of wa
ter flowing down the Wahiawa stream
during freshet months and in the dry
est times the stream Will readily flow
at the rate of a couple of millions gall
Ions daily.
The big tunnel which taps the Wahi-
ava is a splendid piece of work and can
pass millions of gallons of water. The
plantation people have this stream 50
arranged that it can be used at will and
the water diverted to several different
directions either on the fields direct
the reservoirs or the pumping station
in the Hanapepe valley.
In Hanapepe valley are located the
pumping stations. The Risdon pump
has a capacity of 10000, 600 gallons daily
and the Worthington, 100000 gallons.
These pumps throw the water $50 feet
above onto the Eleele fields A num-
Der of artesiau wells were sunk in this
valley but all those formerly used to
supply the Risdon pump went dry. Mr..
Stodart by surface development secur-
ed about 100000 gallons for this pump
and 100000 gallons more for the
WorthingtOn pump. 1t is figured that
100000 gallons can be taken from the
river. The balance REQUIRED comes
from the artesian wells which have not
gone salty at the Worthington pump.
In drifting for surface water Mr..
SIodart goes from Is to 20 feet below
sea level. One drift goes back 80 feet
and two others about $50. All of these
tunnels have developed an excellent
amount of good pure water and the
plan is to ultimately extend them until
the artesian wells can be abandoned al
together
ter system of the McBryde plantation
is the fact that it has been so admir-
ably arranged as to make the water
from any particular source available
for any section of the fields. While
naturally the Hanapepe pumping sta
lions supplys the Eleele and Wahiawa
districts the streams can be carried
clear across to the eastern side of the
plantation, and the same thing exists
with the water from the other side
The Wahiawa water shed is probably
the most valuable source of water for
it supplies the storage for the dry
months.
The party returned with the salts
faction of having passed two delightful
days visiting every place of interest on
the plantation They We're most hos
pitably entertained by the McBryde
Company and the hospitality was dis
pensed with true Hawaiian grace by
Mr. Kinney, Mr.. Stodart and the Nc
Brydes. The luau which the latter
provided at their summer residence at
Laval gulch will long be remembered
by those who partook of the feast and
enjoyed the magnificent sea bathing at
that beautiful spot.
