HEALTH OFFICIALS HAPPY
THE HEAVY RAINS WILL CLEAN
THE SEWERAGE.
New System Which Herring has Plauu.
How the City is Divided.

While the pedestrians are grumbling
about the rainy weather and the mud
dy streets the health authorities are
iubilant. The rain water will clean
the city's crude sewerage and drain
age system, and everybody will feel
all the better for it,
Engineer Rudolph Hering's plans
for the sewerage and drainage of Hon
oulu are receiving the closest exam
ination of President Smith and mem
bers of the Health Department. \
full report together with recommends
tions will be laid before the LegisIa-
ture next month, as exclusively an
nounced in The Star on Wednesday,
the total cost of the system is csti-
mated by Mr.. Herring at S2600O0.
Mr.. Hering's design has been com
puted for 10000 people. An increase
would require additional sewers and
other streets and extensions at the
pumping stations. but not a remodel
| ing of any of the sewers now propos-
ed in the plans
In the business part of the city the
| calculations are based upon a density
of eighty persons per acre. which is
very liberal allowance. Along Berc-
| tania and King streets. as far as Wal
| kiki Stream. and along Nuuanu and
| Fort streets. as far up as School
street. and in the vicinity of Emma
Square. the density of population is
estimated at thirty persons per acre
| About two-thirds of the remaining
territory is assumed as having like
wise a population of thirty per acre
/ = Il;
acre.
In devising works for the removal
| of sewage and storm water it is nee.
essary to determine which of the tive
general systems ordinarily in use viii
best suit particularly locality. IN
some cities it is found most economic
cal to build Il single system of sew
ers to receive both the storm water
and the sewage. In other cities it i;
found best to build two separate sys
TENS. one to receive the sewage alone
and the other to receive the storm
water alone.
\ decision must be based mainly OF
the grounds of cost. Where il is nee
essary to provide for underground re
moval of both storm water and sew
age on every street, it is customary tC
adopt the single or combined system
Where. on the other hand. the sewage
must be collected on every street. ant
the storm water may be allowed e
run off on the surface. the double o.
separate system usually becomes tn,
i less expensive one. Where. in addition
it is necessary to pump the sewage
so as to discharge it at a proper out
fall, and the rainwater may flow int
near water courses without objection
the separate system is again prefer
able because less expensive. Wher
immediate provision must be made 70
the underground removal of sewage
and much of the surface water may
without objection and for some tim,
to come, continue to run its natura
| way, there, once more, the separatt
system is preferable.
On these grounds there is no qurS
ton that for the city of Honolulu tn,
separate system is the proper one. 7
will give more satisfaction in its oper
alton and be much less expensive thar
the other system. 1t is, therefore rec
commended here and has been adopt
ed in the preparation of the plans. Ac
cordingly, there is a system of sewer
for the collection, removal and fina
disposal of the sewage alone. and Their
is a system of drains for the under
localities where this is necessary.
