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. T. H.

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.
