4 SEWERAGE PLAN FOR THE CITY.
Several Propositions Examined and
Reported On.
The Sewerage Committee and Experts
Recommend the Adoption Of
the Newbery Plan.

Some time ago the City Board of Trus-
tees appointed committee composed of
Trustees Pennish, Bragg and Leonard
(the Sewerage Committee), David Fall
coner, James Seadler, City Engineer
Mullany, Mayor Steinman, Trustee Law
ton, DIR, NJ. Gardner and Civil Engineer
w. w. Waggoner, to inquire into the
various plans submitted for new sewer
age system for the city. and to report to
the board which one they considered the
most feasible and best for the city.
The committee selected Messrs. Seadler,
Waggoner and Falconer TO revise the
plans and report the result thereof to the
committee as basis for its action.
The committee met yesterday, all the
members being present except DIR. Gard
ner. Chairman Pennish announced that
the committee was prepared to receive
the report of the special committee ap-
pointed to investigate and report upon
the different plans submitted.
David Falconer read the report, which
was as follows:
Gentlemen: Your committee appointed
TO inquire into the relative merits of the
plans presented for sewerage system for
the city, beg leave to report as follows:
w. r.. CAMPBELL's PLAN.
The system of sewers. as outlined by
Mr.. Campbell, are set forth in one gem
eral plan of the city, set OF specifica-
tions and blue prints of flushing appara-
tus.
No design is shown of sewage system
for the city.
The chief features of the plans are a
new main brick sewer, commencing at
Twenty-ninth street and terminating at
Front street. 1t commences with a diam
eter of twenty-tour inches, anc gradually
enlarges TO a diameter of six feet at
termination.
The form of sewer is circular through
out
The grade of this sewer at Twenty
ninth street for the bottom of the sewer
Is fourteen feet seven inches above bot
tom of the river (city base), and at its
termination seven inches above the bed
OF the river, giving a fall OF six inches TO
the block.
The top of the sewer is so placed that it
will be but one foot eight inches below
the crown of the street. No attention
seems To have been paid to the sewers
which are expected TO flow into il or to
the manner OF making connections.
Additional sewers are shown on Ninth
street, from alley h and Il to 5 street, on
Seventeenth street, from alley q and K to
5 street, and on Twenty-sixth street from
d to l.. No figures are shown giving size
OF sewers, station or connection.
Two rectangular reservoirs are Speci-
fed to be placed on Front street, shown
as circular on "blue prints" thirty -four
by eighty feet, and one seven by sixteen
feet construction Of concrete. The walls
to be carried up to street grade eighteen
feet above the bottom of the sewer.
it Is designed To pump from these tanks
through the levee.
No plans are submitted showing any
designs for head work. His report says
that the contractor will construct suit
able bulkhead outside the Ievee to pro-
tect the levee and discharge pipe, submit
ting plan of the construction be pro-
poses Tor the approval OF the board al the
time he deposits his bid for the work,
No flushing system is proposed, and no
estimates of cost are given.
The plan has no real merit as designed
for a sewage system for the city.
The grades at the east end is much too
high to drain thai portion of the city 10
give reliable, practical service.
Mr.. Campbell has evidently over
looked the construction OF his reservoirs
III detail.
We note the reservoir ought not to be
less than ten feet below the bottom of the
sewers to be OF any service as required to
have some capacity below the discharge
ten feet below the sewer and eighteen
feet from the bottom of the sewer to the
street grade gives reservoir with walls
twenty eight feet high.
The thickness at base with slope of two
inches to the foot (outside verticaD. will
be i've teet, and one foot width at top
making six feet mean thickness of wall
at center three feet. circumference of tank
rs feet, 700 cubic yards of concrete in
the walls and floor, over 5000 cubic yards
of excavation, great part being under
water and affected by the sepage from
the river.
1t would not be considered advisable or
safe to erect building with machinery
designed TO throw 5000 gallons of sew
age In minute over one of these tanks,
especially near the levee or river front
a i've foot three-siXteenth inch steel
pipe Is inadequate for the purposes re-
quired. Alone without some other protec-
ton we see no reason why it is not apt to
to be crushed with the amount of earth
and heavy railroad traffic over it as it
enters the river.
We deem it unnecessary to consider
the plans further, as they fail to comply
with the requirements of the published
call Tor plans by your committee.
NJ. X. MILLER'S PLAN.
The plans and specifications presented
by Mr.. Miller are for combined system
OF city sewage, except in the northeast
ern part OF the city, on about 1870 acres
east OF Agricultural Park.
The present system is utilized with
many additions.
The main features are a main inter-
ceptor from the eastern line of the city
along the alley between r and S streets.
and from thence to the river.
ihe capacity OF the sewer at point of
discharge Is 10000 gallons per minute
Mr.. Miller recommends that the capacity
OF the proposed pumps be fixed and pro-
vision made for storing the flow in excess
OF the pumps. The plan proposes to
make use of Sewage Lake as the only
available outlet as natural reservoir for
Slpage and surface water, and during
times of storm this outlet will be called
into use. The addition, he saws. of a
limited quantity OF very diluted sewage
will not be objected to by the properly
owners below the city. 1t is suggested
that all surplus storm water be stored in
Sewage Lake and suction pipe extend
from the lake to the new pumphouse.
1t IS iurther recommended that the
open ditch on Seventeenth, from street,
be stllI malhtalnea as storm water out
let. He says: While not strictly neces-
sary, it is advisable that the ditch should
be maintained IN its present state ready
for use as an outlet for storm waters,
AS no elevations are shown on the citv,s
blue prints for the district east of Apri-
cultural Park and north of III street, no
sewers are designed for this rapidly
growing portion of our city. Mr.. Miller
says the grades must be light and for this
reason storm water must be exeIuded
from the sewers and special at
tention given to flushing, thus
recommending that separate system
for this territory alone be adopted
otherwise his plan Will not be a success.
The sections south of S street, from Eley-
enth to Nineteenth, are also omitted, as
requiring no sewage facilities for years.
