REPORT ON A
|
GENERAL SYSTEM OF SEWERAGE
Of the City of Hoboken, N. J.
Made in accordance with a resolution of the Mayor and Council,
passed June 11, 1890.
Hoboken, N. J., Sept. 8, 1890.
To the Honorable Mayor and Council of the
City of Hoboken:
Gentlemen — In accordance with your
resolution of June 11th, 1890, the following
report and accompanying map upon a general
sewerage system for your city is respectfully
submitted.
There are many good and urgent reasons
for the adoption and carrying into effect at
once a comprehensive plan of building your
q sewers and draining your low lands, for the
( _ piecemeal and haphazard methods so far
~f-* pursued in the laying out and construction of
3 your sewers, especially of those in the third
-£-~and fourth wards, have not only resulted in
unnecessary expense to the adjacent property
•owners, but considerable of what has been
done will need to be rebuilt in the future in
order to conform with a general system for
_.the whole city.
One of the main difficulties in the problem
was to design such a system as would utilize
three feet below mean high water or eight
feet below the street grade, and one foot be¬
low the present surface of the meadows.
From thence it will continue through Fourth
street to Monroe street; thence north to Fifth;
thence east to Grand street; thence south to
Fourth street; thence east to Clinton street;
thence south to the well, which it will enter
at an elevation of 13.3 below mean high water.
A spur branch extends through Monroe street
to Sixth street, thence west to the boundary.
This line for the main sewer was chosen for
several reasons; first, the presen sewer in
Clinton street is an old wo'oden box which
sooner or later will have to be rebuilt, two
blocks of it is built on piles, which can be
utilized in the construction of the new main;
secondly, the location of the main through
Fourth street and Fifth street not only taps
all the existing sewers, but the route affords
an economical alignment for the future lateral
sewers, thus forming a valley to which all
sewers between Second and Eighth Streets
will flow. These lateral sewers as will be
seen by the map need be but twelve, fifteen,
eighteen and twenty-four inch pipes.
For that portion of the district south of
Second street another valley or intercepting
main through Ferry street and Newark ave¬
nue is provided. It commences at the west
boundary on an elevation of three and a half
feet below mean high water, continues east to
Jefferson street, where it will be five feet be¬
low the same datum; and thence east through
Newark avenue to the well which it will enter
at an elevation of 7 1-2 feet below mean high
water. A spur to the main extends west
through Paterson Plank road to the boundary.
From the well a cast iron tail overflow sew-
9
portion of the city the original condition of
the meadows have been changed, being dam-
k med up by the embankment of Eighth,
Twelfth,Thirteenth, Fourteenth and Fifteenth
streets and that of the New Jersey Junction
ij Railroad. All these cross the entire width of
* the marshes, forming it into five depressions
or basins which receive the drainage from
about 100 acres on the Palisades. One ditch
■eight feet wide and one foot deep runs through¬
out the entire length and finds an outlet in
the cove near the foot of Fifteenth street. As
this ditch continues south to the Madison
street sewer at Fifth street it carries into
these northern districts as already stated more
or less sewage filth. Immediate temporary
relief to this section may be had by closing
out the sewage at Eighth street; constructing
at once as shown on the map a four by eight
feet sewer with proper tide gates at Fifteenth
street to intercept the present main ditch.
Intelligent ditching should be done through¬
out all the streets shown on the city map run¬
ning north and south, and ample culverts
■constructed under the present streets; all
these ditches must be kept constantly open
and in good repair by systematic supervision;
the object being to provide ample outlets for
these marshes, and to keep them free from
^ sewage.
GENERAL SEWER A.GE PLAN.
^ Thb “combined” system, with pumping,
■has also been adopted for this section of the
oily. The reasons which make that method
of draining the most advantageous one for
the territory south of Eighth street, apply
with equal force to this area.
' The map shows the main and lateral sewers
which must be built from time to time as the
future growth of the city requires. The
pump well can be located near Fifteenth
street and Park avenue, and for some years
during the gradual increase in the population
of this section, the Fourteenth street sewer,
which empties out in the current will answer
as an outfall sewer from the pump. It is im¬
possible at this early day to anticipate the
future devolopement of the “cove” sufficiently
to determine on the permanent location of
either the well or the discharging outfall.
The new r Fifteenth street tidal sewer will
answer as the overflow outlet. This should
be extended as shown on the map down Wil¬
low avenue and connect with the present
sewer at Twelfth street, thus making a union
between the upper and lower districts. Be¬
sides, it will afford sewerage to those houses
now in Willow avenue, and this street being
the principal thoroughfare, and most likely to
be built up first, this tidal sewer will answer
the purpose of drainage until such time as the
growth of the district demands the introduc¬
tion of the pumps. Further, as the small
piece of uplands between Tenth and Twelfth
streets, west of Willow avenue, is most likely
to develop before the meadow portion, this
sewer in Willow avenue would serve the
purpose of a tidal main, and intelligent
changes to that end could be made in the
plan without vitiating the general design. To
attempt, however, to extend the tidal system
into the meadow territory, would be to re¬
peat the same errors committed in the south¬
erly portion of the city.
The cost of the four by eight foot tidal sew¬
er will be about $15 per lineal foot.
Pumping capacity to the extent of thirty-
eight million U. S. gallons in twenty-four
hours will be required for this district. This
capacity is determined upon the same data as
to storm water as was used in the lower
section, allowance being made for not only
the one hundred and thirty-five acres within v
the boundaries of Hoboken, but it also pro¬
vides for the possible natural drainage from
one hundred acres on the hill. If, however,
before you introduce the pumps, this hill
drainage is taken care of, as is now under
contemplation, a corresponding reduction can
be made in your future pumping plant.

New York, Sept. 9, 1890.
To the Honorable Mayor and Council
of the City of Hoboken:
Gentlemen —On June 11, 1890, your Hon¬
orable body passed the following resolution:
“ Resolved, That City Surveyor Thomas H.
McCann is hereby instructed to prepare, in
co-operation with Alphonse Fteley, Chief
Engineer of the New York Aqueduct Com¬
missioners, a general sewerage plan of the
city, to be presented to this Board, with their
report, as soon as possible.”
In order to carry out the instructions there¬
in contained, I have have visited Hoboken
several times and frequently conferred with
Mr. McCann. The main conclusions reached
in his report have been arrived at after a
full discussion of all points of importance,
and are concurred in by the writer. It may
not be out of place, however, that, without
referring again to the details of construction,
I should add a few words as to the reasons
which led to the adoption of the plan herein
recommended.
The territory of Hoboken covers an area
of about 720 acres. It is in the form of an
irregular parallelogram (its longest side
north and south), and, originally, was almost
wholly occupied by marshes freely opened to
tidal water, the only exception being a cen¬
tral ridge 270 acres in area on the edge of the
river. This ridge being in the most favorable
natural conditions as to drainage, no special
comment is necessary, with the exception that
its sewers, which are already built, and
which are, I am informed, generally in good
condition, should be properly arranged to
act in harmony with the rest of the system.
4,
4j
)
11
The area covered by the city proper is conse¬
quently limited, but your territory now re¬
ceives in addition the drainage of 150 acres
of the high grounds in Jersey City and in
the town of West Hoboken, on the western
boundary of Hoboken. The drainage of that
territory is a burden of no small magnitude
for your city. I am informed, however,
that you expect to be gradually relieved of
it, as a system of sewerage is being perfected
in the neighboring communities just named.
The size of the sewers has been s© propor¬
tioned as to provide for that district, but the
drainage therefrom should be excluded in
time for the better working of the system
which is now recommended.
From what precedes it follows that the
treatment of the low lands, which were for¬
merly, and are now, occupied by marshes,
has been the principal subject of our labors.
The comparatively small area of your city
and its situation on the bank of the Hudson
river are two very favorable conditions for
good and economical sewerage, but the uni¬
formly low surface of the land now under
consideration renders the problem more diffi¬
cult of solution.
Owing to the location and size of your city
the idea of disposing of the sew r age by artifi¬
cial means, such as chemical treatment or
filtration through earth, must obviously be
excluded. You have indeed adopted from
the beginning the most advisable method,
that of discharging the contents of the sew¬
ers into the river; but, unfortunately, in¬
stead of devising at an early date a general
sewerage system, and of building gradually
your sewers to follow its requirements, they
have been built without preconcerted study,
for the purpose of meeting immediate and
local needs. In making this statement no re¬
flection is intended on their designers, who, I
am informed, were called upon from time to
time to build individual drains, and who, in
the absence of a well established plan, could
only devise to the best of their power the
means of meeting local requirements.
The fact remains that the sewers in the
lower part of the city are built so close to
the surface that the water stands in the
ground a very few feet from the street level;
that their inclination towards the river is
either null or very small, and that their dis¬
charge into tide water is slow and imperfect.
The public seldom realizes the actual condi¬
tion of public works built out of sight under¬
ground, but were it possible to uncover at
once all the sewers now built in the low lands
and to show you their condition, there would
be exposed to view a net of open ditches
more than seven miles in aggregate length,
partly filled with black, offensive silt, while
above it ebbs and flows with the tide a filthy
liquid, the movement of which towards the
river is so slow that the organic matters
therein contained have ample time to decom¬
pose and to emit deleterious gases.
The result of this state of things are:—A
high death rate, inferior sanitary conditions*
general discomfort, and depredation of prop¬
erty.
Your attention has been called before to-
these crying evils, and several times during
the last twenty years the question has been
agitated of improving the sewerage of the
flat lands.
You have recently ordered that the street
grades should not be, in future, below eleva¬
tion five above mean high tide, and I have
no doubt that, in the course ©f time, the ad¬
vantages derived from an improved system
of drainage would induce your citizens to fill
up the portions now built upon where the
surface of the street is much lower.
A very much higher grade than elevation
five would be necessary to enable you to build
a proper system of sewerage working by grav¬
ity only, but similar results can be obtained
at a much smaller cost by lowering the
grades of the sewers to be built and by
pumping.
This mode of sewerage, which is now rec¬
ommended, cannot be considered as an ex¬
periment; it has been tested in a number of
conspicuous instances and found successful in
cases similar to yours. By its means your
sewers can be built with sufficient inclination
to be self-cleansing, their contents can be
quickly discharged into tide water, the pro¬
duction of noxious gases can be reduced to a
minimum if not arrested, cellars can be prop¬
erly built and maintained, and the level of
the water can be lowered in the ground, to
the great gain of public health. Against
these priceless advantages the drawbacks
which may result from the fluctuation of
3 0112 077601
463
12
ground water should not be weighed a mo¬
ment.
In order to diminish the lift of the sewage
by the pumps, it has been thought advisable
to divide the low lands in two parts, sepa¬
rated by the embankment of Eighth street.
To these two parts the same system is appli¬
cable, with the only difference that, in the
southern portion, the existence of the old
sewers would diminish the efficiency of the
plan. They would be drained readily, but
they would not be self-cleansing, and the
level of the ground water would not be ma¬
terially lowered until, in the course of time
(especially in the case of the wooden sewers),
they were gradually replaced by new struc¬
tures built in harmony with the rest of the
system. North of Eighth street, on the con¬
trary, the plan proposed can be fully carried
out.
In both cases the system proposed would
include:
First—A number of lateral sewers to be
gradually built, of sufficient capacity to car¬
ry all sewage and rain water quickly to the
pumps.
Second—One or more main sewers to col¬
lect the contents of those just described and
to convey them to the pumping apparatus.
Third—A pumping station.
Fourth—An out-fall sewer, to convey the
discharge of the pumps to tide water.
Fifth—One* or more overflow sewers of
large capacity to assist the pumps, or to act
in their place, in case of emergency.
Centrifugal pumps are recommended. That
class of engines has been brought to a great
degree of efficiency. They can be established
at a comparatively moderate cost, and are
well adapted to the lifting of sewage, and,
generally, of liquids containing solid mat¬
ters.
In the present case the pumps are cal¬
culated to take care of all the sewage and of
all rain that may fall on the territory. The
small area of the latter makes it practicable
to do so without excessive cost, and in order
to adapt the machinery to the ever-changing
duties that it would have to perform, it is
thought advisable to erect four pumps which
can be used independently in such number as
the quantity of rain fall may call for.
By the erection of a pumping station, of an
out-fall sewer, and of several connections in¬
dicated in Mr. McCann’s report, you can re¬
lieve the southern district materially without
waiting for the main sewers, the construction
of which should, however, follow without
delay.
As to the northern district, on which but
few buildings now stand, while the general
features of the proposed system of sewerage
should, in my opinion, be followed, it is ob¬
vious that its further development must
necessarily depend upon the growth of the
city in that direction.
In conclusion, I must say that a portion of
your sewerage system is now in a deplorable
condition: that in justice to the citizens .
whose lives, as is shown by the health re¬
turns, are exposed to excessive risks, prompt
action should be taken, and that whatever
may be the expenditure that you may have
to incur for the purpose of remedying the
present evils, the investment cannot fail from
being remunerative. If it were represented
that while the present system requires very
little or no superintendence, and that the
proposed plan commits you to a large yearly
outlay, I may be permitted to say that you
are suffering to-day from grave and growing
evils, which would have been prevented if
you had adopted, at an earlier period, the
suggestions of your advisers, and that unless
you decide without delay to meet the cost of
necessary improvements, the legitimate
growth of your city will be greatly retarded.
If you decide to build the improvement
recommended, the whole sewerage / plant
should be put under responsible direction in
order to secure unity of action at all points,
and all future developments of the system
should be made in accordance with the pro- *
ject herewith presented in all its main fea¬
tures.
Respectfully submitted,
A. Fteley,
Consulting Engineer.
