REPORT OF SPECIAL COMMITTEE ON THE SUBJECT OF Water Supply and Sewerage, z TO THE CITY COUNCIL, OCTOBER 4, 1864. CINCINNATI: GAZETTE COMPANY PRINT, COR. FOURTH AND VINE STS. 1864. R E P O R T. City Buildings, Cineianati, Oct. 4, 1864, To The Hoy. City Council : Gentlemen-In obedience to a resolution of Council; the Chairman of the Committee of Public Improvements, the Chairman of the Committee of Sewerage, and the City Civil Engineer, have visited various cities East and'West, with the view of obtaining such information as we could, in a short space of time, upon the subject of Water supply and Sewerage. Having in a very brief way, visited the several cities stated! below, we cannot be expected to give with much detail the several modes adopted by our sister cities for securing a good supply of water, and a good system of sewerage. It being deemed more within the province of our mission to ascertain by actual observation, what had really been done, and what was now doing in regard to the subject of our investigations. First, in regard to the Water supply :- This question, withus, is fast becoming of very great impor- tance, and, one which must be met by our authorities in the most liberal and enlarged spirit. And with a view of engaging the attention of our citizens, as well as that of those having this matter immediately in charge, we have prepared the following statements of what other cities are doing in this matter. 4 Taking the cities in the order in which they were visited: ST. LOUIS.-With a population about equal to our own, and situated as ours, on one of the great rivers of the West, obtains its supply by pumping from the Mississippi. Their reservoir is an artificial one, elevated about 150 feet above the river, and is "regarded only as a make shift until new and im- proved works are constructed and brought into use." The en- gines for raising the water, are placed at the upper part of the city, but much complaint is made that the water is taken from a portion of the river too near the business centre of the city, and the authorities are urged to obtain the water further up the stream. The City Engineer in a communication to Council in March last, says, "new works should be commenced as soon as the preliminaries can be settled, for there is no time to lose. A commission of citizens, aided by an experienced engineer, is in my opinion the best mode that can be adopted for devising and executing a proper water works extension." CHICAGO.-This city obtains her water from the Lake, by means of pumping engines. The water being forced into the stand pipes from which it is distributed throughout the city. These pipes are generally at an elevation of about 80 feet above the Lake. Owing to the contamination of the river, and shores of the Lake near the city, by the large amount of offal and filth thrown into them, by the various slaughtering and manufac- turing establishments of the city, and by the sewers, the city authorities are now constructing a tunnel under the Lake, for the purpose of obtaining "water from a point two miles from the shore. The cost of this work will be very great of course, but the object, the obtainingpure water in abundance, is considered sufficient to justify even a much greater outlay. DETROIT-Is also supplied by pumping from the Lake, the same causes for polluting the water, not existing here as at Chicago, the city is abundantly supplied with excellent water. CLEVELAND-Is supplied from lake Eric, the water being pumped by engines built under the direction of our former townsman and Superintendent of our Water Works, T. R. 3 Scowden, Esq. The reservoir is an artificial one, and is ele- vated some 160 feet above the Jake, from whence the water is distributed by means of pipes throughout the city. BUFFALO.-This city also obtains its water from the lake by pumping. The reservoir is an artificial work 85 feet above the lake. The works are owned by a private corporation. ALBANY is supplied by gravity. The water is obtained by gathering it upon grounds some distance from the city and storing it in 'lakes or reservoirs formed by throwing dams across the creeks and natural drainage ways of the country. These lakes and storage basins are large and beautiful aheets of water, the largest called Rcnsellear Lake, contains thirty-nine acres of surface, the smaller, called Watervleit or Tivoli Lake, has thirteen acres of surface. In addition to this, is a subsiding or purifying reservoir of eight acres con- nected with the latter reservoir for the purpose of receiving the water during storms from which it is passed into the storage reservoir after it has become somewhat purified. The water is conducted to the city a distance of four miles from the larger lake, or reservoir, in a brick conduit to a distributing reservoir, entirely a work of art of seven acres water surface, and from this reservoir passed through pipes to and through the city. Watervleit or Tivoli Lake is situate below the larger lake and supplies the lower portion of the city. The gathering erounds from which the water is collected into the storage basins, or lakes, comprise something over three thousand acres of land, and belongs wholly to the city, having been purchased for the purpose, and the whole area draining into these storage basins is controlled by the authorities so as to prevent con- tamination and impurity. The soil in the vicinity of Albany is peculiarly well adapted to this mode of supply, being a light sand upon a subsoil of tenacious clay, and the heaviest rains are almost wholly ab- sorbed as soon as fallen, the water percolating through the sand and draining gradually into the lakes many weeks after its fall, thus becoming purified and clear. It has been ob- 6 served, by those having charge of these works, that the heav- iest rains rarely cause an immediate rise in the lakes or storage basins. These reservoirs, situate as they are amongst the hills and ravines of the city suburbs, with the surrounding grounds kept in the neatest order and under excellent superin- tendence, having beautiful forest trees in their vicinity and all rank vegetation kept down, offer a most pleasing landscape to the eye and are spots of rare and refreshing beauty. BOSTON, it is well known, is supplied by gravity, the water being collected in several natural ponds and brought to the city by means of a conduit. In 1848 Boston completed her Cochetuate Works. In building these works they have taken into consideration the future growth of the city and have made ample arrangements for an abundant supply. The source from whence the water is drawn is a lake situate in an elevated part of the country twenty miles distant from the city, remote from the habitations of men, and secluded from the seats of all such occupations as might subject it to causes of impurity. The lake covers an area of a mile square; it is of great depth; in some places seventy feet deep, and is supplied by the rains which fall upon a large surround- ing country, as well as by springs and streams never liable to be rendered impure or turbid by inundation. The waters ot the lake have flowed for ages through a remote part of the country to the ocean. Their natural outlet is now forever closed and a new channel has been formed by the excavation of the intervening barriers of earth and rock. Through this channel a covered aqueduct of brick masonry has been built to secure the flow of a uniform current sufficient to supply the wants of the city even should its population become double what it was at the time of the completion of the work. The area of the lake, when raised to the height intended, will contain two billion of gallons, above the level of the con- duit by which it is conveyed to the city, and this amount can be increased, if required, by other ponds in the neighborhood, or from the Sudbury river, which can be entirely commanded, if needed, under the charter granted by the State. 7 NEW YORK, as all know, is supplied from the Croton river by gravity. This is an immense work, and for the purpose of obtaining pure water in abundance, the city authorities did not hesitate to enter upon the most liberal expenditure of money to attain the desired end, and her aqueduct thirty-seven miles in length, and her magnificent reservoir of nearly one hundred acres surface water in extent, and having a capacity of over one thousand millions gallons, built within her city limits, ranks the first in this country-the capacity of the aqueduct being more than equal to the whole flow of the Croton river at an average stage of its water, and capable of delivering daily more than 60,000,000 gallons. BROOKLYN, containing a population not much greater than Cincinnati, has with commendable energy and liberality on the part of her city authorities, constructed an admirable and substantial work. Being situate on an island, with no great rivers or lakes, she has extended her arms, as it were, and grasped the waters of the heavens and by means of gathering grounds of some sixty square miles in extent, collects and stores the waters in no less than twelve different ponds or lakes obtaining a minimum daily supply of 20,000,000 gallons. From these storage basins the water is brought 12| miles in a brick conduit, capable of furnishing forty millions of gallons daily, to a point near the city, from which it is pumped by steam a height of one hundred and seventy feet into an artificial reservoir of twenty-five acres in extent and contain- ing 161,000,000 gallons. From this reservoir the water is distributed by means of iron pipes through the city. Another reservoir, built for the purpose of supplying the higher part of the city, has a capacity of 20,000,000 gallons. The water is raised by steam to this latter reservoir a height of fifty feet. The soil of Long Island, like that of Albany, is well adapted to this mode of supply, being composed almost exclusively of sand, through which the water filters and be- comes pure and clean before reaching the lakes and storage basins. PHILADELPHIA, having the magnificent Schuylkill not only for supply but for motive power, is so well known as to hardly need a notice here. Her water is of the purest and in 8 quantity sufficient for all her demands, only needing to increase her machinery to increase her supply indefinitely. BALTIMORE is suppliecflby gravity. The water being col- lected at a point about five mjles distant from the city in a valley of a stream known as Jones' Falls, in which by the erection of a dam across the valley in a narrow pass near what is com- monly known as the Relay Station of the Northern Central Railway, whereby the flow of that stream was arrested and its waters forced to accumulate in the natural basin into which the valley expands immediately above the dam. This forms what is known as Swan Lake Reservoir, which contains on its water surface one hundred and sixteen acres and has an available quantity of water of 400,000,000 gallons. From this lake the water is conveyed by a conduit a distance of a little more than three miles to an elevated point about a mile and a half from the northern limits of the city, where it terminates in another reservoir called the Hampden Reservoir, formed by a deep ex- cavation in the natural earth in great part, a portion consisting of an artificial embankment of earth. This reservoir has about eight acres of surface water and a capacity of 50,000,000 gallons. From this reservoir the water is conveyed in two distinct pipes of thirty inches diameter each to another reser- voir known as Mt- Royal Reservoir, having about five acres of water surface and a capacity of 30,000,000 gallons. This res- ervoir is supplied from a head sixty-seven feet higher than its own surface. From this reservoir pipes are laid to and throughout the city. The total cost of this work is not quite a million and a half of dollars. We have thus, in a very hurried and brief manner endeav- ored to present the result of our observations. An abundant supply of good water is regarded by all as worthy of almost any expenditure of energy and means; and we will here say that notwithstanding the apparent liberal provision which many of the cities have made, they already begin to feel the necessity of husbanding their resources and are taking measures to increase their present supply. New York, Boston and Philadelphia are now agitating this question We make this statement to show that it is necessary to provide 9 very liberally for the future wants of our population, so great is the increase in all our cities; and all the reports show that an increase of consumption every year is greater in proportion than the increase of population. Our city has now arrived at a stage when this question must be met, and we ask that it may be met in a spirit of liberality and wise foresight. The vexed question of the source of sup- ply, and the mode, has yet to be determined, and we desire to see it undertaken willingly and promptly; and in order to do this, in the most thorough manner, we would suggest, without intending to disparage in any way the labors of the present and past Trustees of the Water Works, that a commission composed of the Mayor of the City, the Trustees of the Water Works and a committee of three from this Council, be formed for the purpose of taking into consideration this whole subject of water supply, examine thoroughly the various sources of supply as drainage grounds, the Miami and Ohio rivers, the subject of storage basins and lakes as connected with the drainage ground, and also with the supply by pumping from the Ohio, and with this view we submit a resolution herewith, namely: Resolved, That the Trustees of the Water Works be invited to meet with the Mayor of the City and a committee of three members of this Council, for the purpose of forming a com- mission to take into consideration the best method of obtaining an abundant supply of pure and wholesome water for the city, and that said commission be and are hereby authorized to in- stitute and carry out all requisite preliminary surveys and in- vestigations for ascertaining the most economical and practical mode of supplying our city with pure water, and report to Council at as early a day as practicable. It may be of interest, in this connection, to present the daily average amount of water supplied to different cities in 1860, as showing what we may have for a basis of calculation for our own city. 10 New York average per inhabitant, 51.6 wine 'gallons. Philadelphia " " 35.9 " Baltimore " a 25. " Boston " " 96.9 " St. Louis " " 40.1 " Cincinnati " " 30. " Chicago " " 42.9 " Buffalo " " 47.6 " Washington City | and Georgetown " 19.3 Albany u <c 69. " Detroit " " 30.5 " Jersey City and Hoboken " 51.4 " Making an average of 45.01 wine gallons per each inhabitant. It is a fact noticed by those who have given their attention to this subject, that the actual daily average quantity of water supplied, very rarely, if ever, diminishes in a city. In ancient Rome the amount furnished each inhabitant was 375 gallons, being a much greater quantity than is furnished by any city in modern times. We also deem it proper, on the present occasion, to present the analysis of water supplied to different cities as well as the analysis of water in our own vicinity, merely giving, however, the amount of solid matter in grains found in a wine gallon of water.

In reference to the sewerage of the cities we have visited, we will endeavor, in a brief manner, to give a synopsis of what each has done and is doins. ST. LOUIS has no permanent plan of sewerage, but is building sewers as needed, and the authorities are doing all they can for the adoption of some well-devised system. The public sewers are built along the main course of drainage, at the gen- eral expense, to pay which there is a public sewer tax assessed. District sewers are constructed at the local expense of the property. CHICAGO, it is well known has arranged, and is carry- ing out an extensively excellent system of sewerage. 'It con- sists of brick mains and glazed stone-ware pipe, for lateral drains. The expense of constructing these sewers is borne by the city-bonds having been issued by the city under the au- thority conferred upon the sewerage commission by 'the Legis- lature. The city has now about seventy miles of sewers built. DETROIT has no system yet established. CLEVELAND has adopted a general plan of sewerage, and is engaged in carrying it out, using brick mains and glazed stone-ware pipe of a similar character, and, in .fact, from the manufactory-the Akron W orks-that is .now supplying our city with sewerage pipe. ALBANY has no system, though the authorities are taking measures to have a law enacted by the Legislature authorizing them to devise and form a permanent plan of drainage of their city, similar to that of Brooklyn. A number of miles of sewers are built, into which is drained the cesspools and surface waters of the older portions of the city. The sewers are mostly built of brick, though a cement pipe, manufactured in New York, is now being introduced. BOSTON has a well arranged system of sewerage, and the glazed pipe sewers are being gradually introduced in place of 12 the smaller brick sewers which were formerly universally used. The corporate authorities of Boston pay one-fourth of the cost of constructing sewers, and the remaining three-fourths is paid by assessment upon the value of the land (not including improvements) benefitted. BUFFALO has not established any system, but they have been building sewers for the past ten or twelve years as needed. The sewers are all of brick, the largest being 5J feet interior diameter, and drains about two square miles of territory. The smallest sewers are eighteen inches, built of brick-no junc- tions being put in, and when it is needed to tap the sewer it is broken into and the junction formed. All sewers are built only on petitions of property owners, and are paid for by assessment upon the front feet of the property on the street in which the sewer is built. Cesspools are drained into the sew- ers, and all inlets are trapped. The total length of sewers built up to this time is about 60 miles. NEW YORK has at present some five hundred miles of sewers and drains built. Without having any regular system arranged for the whole city, the authorities having charge of this branch of improvement adapt them as best they can to works heretofore built. The cost of building the sewers is borne by the property adjacent, the city paying the contractor, and then collecting the amount from the property by her own officers. BROOKLYN-situate somewhat similar to our own city in regard to having a good elevation for drainage and outfall for the sewers, has adopted a complete and comprehensive system of sewerage for the whole city, and calculated for all extensions which the future of the city will demand. This system consists of brick sewers for the mains, and glazed stoneware pipe for the lateral drains. The mains have six inch junctions inserted at intervals of about 20 feet for house connections. The whole work is done under the direction of a Board of Sewerage Com- missioners, organized under an act of the Legislature of the State, who are appointed by the City Council for a long term 13 of years, and serve without compensation. These Commission- ers were authorized to borrow' upon the credit of the city from time to time, such sums as might be needed to meet the cash outlay in the construction of the sewers, (in anticipation of the collection of the assessments,) not however to exceed five hun- dred thousand dollars, at six per cent, per annum, the bonds to be payable in not more than three years. The sewers when constructed are paid for by assessment upon all the property of the district drained-the city paying the contractor as the ■work progressed, and collecting the assessments by her officers appointed for that purpose. This plan has been in operation now some five or six years, and something over one hundred miles of sewers have been constructed, the city in no instance failing to collect the assessments. PHILADELPHIA has no general plan of sewerage arranged with reference to the whole city, many portions having been sewered many years ago without reference to any system; but the authorities are gradually introducing system into the sewerage works of the city. In all cases where sewers are built, the property owners on each side of the street are taxed seventy-five cents per front foot, without regard to the size or cost of the sewer, the city paying the excess if there is any, or taking the excess if there be any. An annual rental also of from one dollar to ten dollars is charged parties using the sew- ers, to defray cost of inspection and repairs. The total length of sewers and drains built in Philadelphia, is nearly four hun- dred miles. In conclusion, we arc pleased to state that we are satisfied that the system adopted for our city as arranged by our City Civil Engineer, in accordance with the act of the Legis- lature upon this subject, is in conformity with the most appro- ved method as adopted by other cities, very nearly conforming to that of the city of Brooklyn, whose system is now regarded as the best in this country, being the result of the experience of most eminent civil engineers, and comprises all that is known of this matter both in this country and Europe. We are of the opinion, however, that a modification of our present sewerage 14 law, so as to make it conform as nearly as the circumstances will admit to the act regulating the sewerage of the city of Brooklyn, will be a great benefit, and contribute materially to the successful workings of the system. It seems to be the opinion of the better informed in all the cities we visited, that works of this kind should be under the exclusive control of a Board selected with special reference to their capacity for, and zeal in regard to, carrying out these matters of a purely sanitary character. The sewerage of a city like ours, involves a heavy expenditure of money, great care in the selection of its agents, and the determination of, and carry- ing out a well settled policy. Our Board of City Improvements have already a very large amount of business to transact, the committees appointed by Council cannot be permanent, nor can the members of Council give that attention to the subject which its importance demands. A Board of Commissioners, composed of such of our citizens who would readily undertake a great sanitary work of this character, to be selected and appointed by the Mayor and con- firmed by the City Council, to serve for a term of ten or twelve years-, without compensation, would, it is believed, prove highly conducive to the best interests of the city. We therefore submit the following : Resolved, That the Committee on Sewerage and Drainage, in connection with the City Civil Engineer and City Solicitor, prepare an act to be submitted to the Legislature at its coming session, providing for the appointment of a Board of Commis- sioners to take charge of the sewerage of the city, and report the same to the Council at an early day. We cannot close without expressing our thanks to the authori- ties of the various cities we have visited, for the unform kind- ness and courtesy shown us, and the facilities every where offered us in obtaining information in regard to the works in their respective cities. The authorities of several of the cities visited, desired to express their welcome in a much more for- mal and public reception than the nature of our hurried visit would permit, and we were therefore under the necessity of 15 declining all such testimonials, hoping, however, when they may have occasion to visit our city their engagements may not be so pressing as to prevent us from extending to them the hospitalities we were compelled to decline.
