goes into the River and Queen street
main. In fact sewerage from all of the
business port of town goes into the
River and Queen street main.
The tributary or connecting lines to
the main lines are called in the re-
port laterals. These are so directed
from different parts of the city that
full advantage is taken of natural
grades, everything reaching the well
in Kakaako by gravity.
The drainage system is shown in
the drawings with blue ink, red lines
being used for the sewerage mains and
laterals.
These are the drainage routes:

Pacific Mail wharf line No. l runs up
Richards, over to Halekauwila, to Ala

The question of utilizing sewage was
formerly thought to be of considerable
importance for economical reasons. At
the present time the utilization in most
cases is known to be a matter Of con-
siderable expense, the greatest value
of the sewage being it's water value
wien used for irrigation.
common method of disposal in
England is to precipitate the suspend
ed organic matter by the addition of
certain chemicals This eXpedient al
lows the clarified sewage to be dis
charged into a running stream, or
large body of water, without causing
the objection that would result from
the discharge of raw sewage. Precipi-
t26On however. when adapted to the
needs of your city, requires so large
an expense that it cannot be recon-
meled. Moreover, unless the works
are conducted with great care, the
mehod meets with objection from the
offensive Odors that may then arise.
The only proper method and the
least expensive one for the disposing
of he sewage of Honolulu is by
discharge into the ocean at such a
poilt and under such conditions that
a thorough dilution may be obtained.
This method has been practiced in
mary large cities. and where the con-
ditDns are proper and the works are
suihbly designed, complete satisfaction
has been given in every case. The
Cit of New York discharges its sew
age into the adjoining water courses,
and no evidence remains of it. The
Cit of Boston discharges its sewage
int, the harbOr with the outgoing
tide and it disappears completely from
siglt after running out to sea a short
distance.
