trict pump so arranged as to be practically
automatic and operated by pow
er to be obtained either from
dynamo at the city water
works, from an electric street car line or
other sources may be most economical. The
total expense of operating this machinery
will not exceed $500 per year, which capt.
talized at per cent. would equal $1,000
original cost
No evil can ever result from discharging
sewage into the river at the foot of Fahm
street at the upstream end of the city, but
1t would be possible at any time to cut It
off, and to convey ali the sewage from the
western side through an interceptng sew
er at River street to the Randolph street
outlet, should this for any reason be de-
sired.
Should IL be desired at any time TO cut
off all sewage from the Savannah river, a
pumping station near the foot of Randolph
street would receive all of the sewage of
the city and deliver 1t to Wilmington river,
or to publication works wherever located.
Nearly all of the sewers south of Gwin-
nett street cross the Savannah, Florida and
Western railway Careful study showed
this to be the most economical method.
The crossing sewers are nearly all eight
inches in diameter and the grades are fa-
vorable TO the work being done quickly
and ineXpensively, and without interfer-
ence with railway traffic. Wherever a
sewer crosses a railroad iron pipe will be
used
The intercepting sewer at River street II
built, will be twenty-four inches i'm diam
eter 1t follows close to or between rail-
road tracks for nearly its entire length,
and Is genrally near to the surface. For
this reason 1t would be necessary TO use
iron pipe for the entire length; all the more
so because during high tide this sewer
viii work under slight pressure.
Nearly all of the buildings between Bay
street and the river now have direct out
let's for the discharge of their liquid
wastes. This is not Objectionable and
nothing would be gained by iuterceptlng
this sewage with a view to reducing the
number of points of discharge. These
buildings cannot easily be connected with
the two outlets shown on the plan.
1t is impossible to provide a gravity out
let to the river for the sewerage of Col
linsville the territory south OF Wheaton
street, and east of East Broad street The
sewage of this territory must be brought
to pump well, which is located on Wheat
on street. near Bilbo canal
IT is to be pumped from this point to the
main sewer in Randolph street, at the cor
ner of Liberty street Until Collinsvle
is much more thickly settled than it now
Is, the necessary pumping can best be
done as in the case of Yamacraw, by
electricity
The main sewer in Collinsvlle, at its up
per end In Paulsen street, has been kept
low enough and made large enough to
furnish an outlet for the area south of An
derson street and east OF East Broad
street. when this Is brought within the
city limits. To meet this requirement, the
head of this main sewer has been placed
about four feet deeper than would other
wise have been necessary
Under plan No. 2, the lateral sewers
have substantially the same arrangement
and grade as those of plan No. /, nor Is
any change made in the main sewer south
of Bolton street lane. which extends
through East Broad street, Tenth street,
Price street, South avenue, Twelfth street
and Florence street. 1t receives the later
ais from the whole territory south OF An
derson street and east of the section
drained to the Farm street outlet. All of
the main sewers north of Bolton street
lane are entirely different In their ar
rangement from those in plan No. l, be-
cause the outlet to which they deliver Is
a pump well in Collinsyille, at the corner
OF Paulsen street and Bolton street. I'm
der plan No / these main sewers fall to-
ward the Savannah river, whereas in plan
No. they fall away from the river to-
ward Pausen street pump we'll
All of the sewage of the northwestern
quarter of the city will be conveyed by a
main drain laid through Gordon street
lane to the eastern side of the city, thence
through East Broad street to the Bolton
street lane main sewer. leading to the
pump well. 1t will be necessary to supply
a supplemental pumping system of small
size for the Yamacraw district, practical
ly the same in design and operation as in
plan No. /.
Features Common to Both Plans-In

found that the grade Of the main
sewer on East Broad street would inter-
fere with the nine-foot Bolton street storm
water sewer and provision has been made,
as shown in the detail drawings, for car
ryng the main under the Bolton street
storm sewer, by an inverted siphon of
iron pipe; a fall of half a foot to the
main sewer is given at this point to COM
pensate for additional friction
The sewers are calculated for a popula-
ton of 10000, each person using sixty gal
Ions Of water per day one-half of this
flowing In eight hours, or at the rate of
ninety gallons per day. This allowance
is doubtless much more than the actual
use, and as ground water, If encountered

in the sewer trench and discharglng in
most cases into a natural water course, or
a storm sewer, II was not necessary to
water which 1t might be found necessary
to discharge into the sewer system and
to increase the size OF the conduits.
Care has been taken to provide that all
property within the city limits may be
connected with a sewer by the shortest
route and the most convenient and mex
pensive way. For this reason sewers have
been placed In lanes, wherever lanes ex-
list, and in some cases In what are now
private lanes. Should the owners of pri-
vate lanes object to this, such sewers
may be omitted. In this case the property
owners will simply subject themselves to
the greater cost of connecting with more
distant sewers in public lanes and streets.
AS plumbing fixtures are nearly always
al the rear Of buildings, the advantage Of
direct rear drainage Is apparent.
The small blocks between the parks in
the northern section of the city are reach
ed by short branch sewers, from which,
in streets in the rear of houses, short
lines of slx-inch sewers are extended, each
terminating with a lamphole. These six
inch sewers are practically combined
house drains, laid on steep grade. None
Of them will receive the sewage of more
than six or eight houses. This arrange
ment Is quite as efficient and somewhat
less expensive than the construction OF
longer lateral sewers running east ana
