T ON THE NECESSITY OF NEW WORKS FOR ^iicreasiiio tfje Suppfi) of Water TO THE C ^TY OF QUEEEC^ NOW INSUFFICIENT FROM EXCESSIVE WASTE AT THE SERVICE PIPES AND ELSEWHERE WITHIN TJIE CITY. To His Worship the Mayor, B. McGic, and J. B. Pruneau, Esquires, of the Joint Committee of the Fire Insurance Co7npanies and City Couti' oil of Quebec : — Gentlemen — Having been requested by you "to report on tbe present state of tbe Water Works of Quebec, witb recommendations bow any defects can be remedied;" and to report my "vie.vs as to tbo mode of preventing waste," and whetber " tbe present supply of water, if properly regulated, is sufficient for the city, and, if not, wbat 1 would suggest to be necessary, witb tbe probable cost tbcreof ; wbetber a " reservoir or a double set of pipes," tbe report to be based on a population of 100,000 inbabitants ; I beg leave to offer tbe following statements as the results of my investigations : — Concerning tbe present state of tbe Water Works, so far as I could examine tbem, I found notbing tbat indicated unsoundness, insecurity or imperfectness beyond wbat ougbt to be expected in a work of the kind, constructed, as it was, some ten years ago. The 18-incb feeding-main from Lorette to IMouut Pleasant was tested and found exceedingly tight, as will be shown liereafter. Tbe greatest change that has taken place is the reduction of the bore of the pipe by oxidation ; this was to be expected as at the time the pipe was laid down there was no known remedy against such a result ; and oven at tbe present day tbe most perfect pro- tection that has been applied can only be considered as a palliative, that of dipping tbe pipes as soon as cast, before oxidation takes place, in a hot bath of Dr. Smith's Patent Coal Tar Yarnisli. This coating is considered the best, and has been generally used, so far as I am informed, throughout the Northern States within the last sis years. It was applied to the Brooklyn pipes wliere cast-iron was generally used, and at Cbarlcstown where the oO-inch force-;Lain and tbe 24-inch feeding-main are of iron. There is some uncertainty as to the duration of this varnish — it will probably protect tbe pipes for some'scven or eight years, but not much longer. The effect of the incrustation on the 18-inch feed-main, as laid down from the Chateau d'Eau at Lorette to Mount Pleasant, appears by our experiments to have been, to virtually reduce the calibre of the main from 1.50 ft., its original size, to 1 28 h—tUi is comparlns tho discharge computed on a fltraiglit and smooth pipe of nnif^^m sLt^'on tZughout its length, free from all obstruetions except fnctxon of the rter against its interior surface, ^ith the discharge as ascertained by guugin,rtho water, at the Chateau d'Eau, that actually flowed tl^j^o^g^ td M in nine under a known head and fall, using the same lormula and head and fall in ffiog tbe comparison. This comparison shows the pipe now in use to be of „o mor^ v^alue, as stated above, than one of 1,^ foot diameter, clean, straight and smooth, showing a loss or difference of diameter of a ^|^ foot, or 2^ inches. If there were no Other way to account for this reduction of the discharge than the incrustation, the experiments would show that the pipe had actually an lu- crustation oTo 11 ft., or 1.^^ inch thick; but, without doubt, several other causes do exist such as eccentricloinings, irregularities in the alignment and ourvitures, enlargem nL of bore at stopcocks^nd air-cocks, and possibly heavy subs^^ncns like Btonefwhich were accidentally left in the pipe at the time it was laid down ard could n^t be sToured out afterwards ; if anywhere, these would probably be found aJthe foot of Savageau Hill, or between the hill and the River St. Char os, which portion of the line,%lthough an attempt was made, could not be thoroughly .ooured for want of a sufficient supply of water at Mount Pleasant. ^ , . ^ _ , In all the computations we may have occasion to make on the subject of supply, a similar reduction of the diameter of the pipes will be made before computing he discharges, not regarding the possibility of keeping the pipes clear of incrustation many years by the modern practice of varnishing with prepared coal tar. . This filling up of the pipes by oxidation in the form of iubercles, more or less hollow extends throughout the whole system of the distributing pipes within the city : ^nd is, without Question, one of the principal causes, why, in case^of fires oc/urring in districts\upplied by the smaller pipes, there is sometimes found an insufficiency of water and pressure at the hydrants, greatly increased of course by theTesent practice of the tenants leaving the water running from their services _ Were this waste of water controlled by some stringent law or otherwise, I am ot ooinion its effect would be apparent. . , . , . • „„„„ ^ At the time the Water Works were commenced, 4.inch service mains were gone- rally used for the smaller mains both in Great Britain and the United bta e^ Experience in England and Scotland at that time, had ^^^^^.t^^^J,, '^^ ^-'"^J; pipes, often used then to save cost, were too small because of the fiUino up bj oxidation, as at Aberdeen, where I found u ainch service mam for a considerable extent was being taken up, and a 4-ino.h sukstituted ; the former failing to perform its office by the accumulation of rust. . . ■, ■ , i ;ri Both at New York and Boston, then introducing water 4-inch pipes woio Lid down extensively for the outer or extreme branches of the distribution ; but lo the more recent distribution of water at Brooklyn, N. Y., no service mains less tlian 6 inches have been laid of cast iron, and these have, it appears, been coated with the coal tar varnish, , i ^.^jrio As varnish may decay or wear ofi, and not eventually prevent the ";u=il f ifa- tioD, another kind of pipe has been introduced in several cities in the United States, where the pressure is not so excessive as at Quebec, which if lound to be as mperishable as cast iron, will be a valuable substitute for the latter in the distribution of water in cities generally; especially for all the smaller FPes of a Bvstem ; but for the larger mains of 16 inches and upwards, i may not be found Z well adapted. I allude to the " H>/Jraulic Cement Pipe" as laid down by the -Jersey City Water and Gas Pipe Company." This p.pc is formed by lining with Hydraulic Cement (such as may be made at Q.u^bec), a sheet-i on pipe strongly rivetted along its joint, and whe»dry laid down in the rcnch on a bed of the same kind of cement, coanecting the pipes together with a wrought iron thimble after the manner the drain pipes at Quebec were laid, covering the whole body of the pipe including the thimbles at the joints with the cement, I '^ smooth pipe cept frictioa lertained by the existing and fall in to be of no itraight and hcs. charge than ually an iu- Dther causes I curvitures, bsfancfis like I down, av.i bly be found larlos, which ghly pooured 3ct of supply, smputiug the ' incrustation [ar. more or less es within the case of fires mes found an of course by ;heir services, •wise, I am of ns were gene- rnited States, at the 8-inch filling up by a consideriiblc ug to perform [pes were l;;id n ; but in the ains les"! than jn coated with e usual oxida- iii the United f found to be ; latter in the Her pipes of a y not be found laid down by is formed by j), a sheet-iron le trench on a with a wrought 1, covering the th the cement, I 8 thus completely enveloping and isolating the sheet-iron tube both from air and water; in this state, it is found by examination, that after being exposed ia the work 16 years, the pipes are perfectly free from oxidation . About 300 miles of this pipe have been laid in the United States during the last 18 years. Its cost in the States IS about s or J that of cast-iron. There can be scarcely a material better calculated for preserving the purity of water than the cement of which this Dino IS made. ^ ^ Can the ffj/chunts at Quebec be tmpro ted ?— This is an important question in their present form, little it is believed can be done to improve their efficiency' except to remove any accretions that exist on their interior surfaces and in the lateral or branch pipes that connect them with the .street mains: any important change would bo attended with considerable expense. Should, however it be deemed necessary to make such a change it would be well to try a recent and very ingenious invention introduced by the patentee, Mr. Loury, of Pittsburg, Penu His Hydrant is attached directly to the street main, generally on the top of the three or four- way branches at the junction or intersection of two streets risin" verticiilly in a well .surrounding it, to near the surface of the pavement the well being covered by a cast iron frame and movable circular cover about 1'^ inches diameter; the vertical pipe having a diameter of some 10 or 12 inches fonraing one casting with the branch itself, and of course admits the water freely from all three or all four mains, as the branch may be one of three or four ways when used in case of fires. A large stop valve closes the top of the vertical pipe' capable of being forced down against the pressure of the, water by a screw nf{er the copper /iose-6ra«(/t, which the firemen bring with their engine, has been screwed to the top of the vertical pipe. The hose-branch carries at its upper end four to eight separate n«zzles to each of which a hose may be screwed. This Hydrant is very powerful and well calculated for supplying several engines at a time whe- ther hand or steam as the hydrant cannot easily be exhausted.* The principal objection to the general introduction of these hydrants into Que- bec, arises from the difficulty there would be of keeping the snow and ice clear from the surface of the streets for a limited space around them; and perhaps from *The following is a description of a trial ef one of these kydrantg in Boston which I witnessed, and is copied froiu C. L. Stevenson's Report on supplyine- the City of Lynn with water, dated September 1, 18C4:— "The advantages arising from such an ex- cess of supply from the mains to the hydrant were so well shown in a trial made in Boston in 1863, that a brief account thereof is pcrtinetit. After an exhibition of the powers of this hydrant at Brooklyn, 1 requested Mr. Loury to send one to us as a sample and if possible, for trial. By the courtesy of the Boston Water Board, and the Superintendent of the eastern division of the Water Works, every facility was afforded for a fair trial of Its merits. The hydrant, a 4-way 6-inch was located in Winthrop Place, near Frank- lin street, at the intersection of two G-inch, pipes ; a 3.w«y 6-inch branch being taken out toadmitof Its introduction. The Fpare end of the hydrant was closed by shutting th» gate therein. The delivery was therefore such as could be obtained from eighty-five snuaro incnes of pipe area, lessened by such accietion as has taken place in the iron- so that the actual ettoctire area would probably not exceed 75 square inches. ' " To this hydrant four of the most powerful of the steam fire-engines in the city were attached by 4.inch couplings. The indicated pressure on the water-gauge, before startinn the engines, was 35 pounds. The engines were fired simultnneously, and, at the end of twelve minutes, were throwing nina powerful streams of water, subsequently increased to thirteen. With the nine streams the pressure on the water-gauge was thirty-two pounds, and with the thirteen streams was reduced to thirty pound» ; thus of course showing an excess of pressure from the main of that amount. This result, so 'contrary to general expectation, was most satisfactory, in showing the ad mntnge of tapping the mains at their junctions. rr e "Upon this same line of 6-inch pipe were located several hjdrants of the usual style To one of these, one steam fire-engine was attached. When throwing two streams the effect of exhaustion of the hydrant was noticeable ; and the interruption to the stream as shewn by the air-spaces, denoted that the engine was dralliug from the main."

It would bo well if there '!0ulu be siifheii.nt water introduced into the city to allowoftho conanuancc of this waste, as the climate is a maximum cold one, m:tking it difficult, at least expensive, to guard the service pipes distributed through ahou,«c from frost; tho elfect of waste-water in washing out the drains is beneficial la a sanitary measure. That a great waste docs exist from the services is shown by the experiments which were earried out la.st autumn, the results of which will be harein exhibited. There should be power in the City Government to control thin waste, or to charge a proportionate price for what is used over and above what was originally estimated to be .--ufficient for an individual, viz., 30 imp. galls. There are no mechanical means by which the supply can be cheaply tiaug d to the citizens; the meter is the best method we know "of, and that would be costly, reriuire frequent repairs, and be especially liable to become deranged by the action of fro^t. There is another invention called J. W. Bishop's improved patent water pressure regulator, by which the pressure ou the services could be equalized throughout the city, provided the head of water could be kept constant or at the same general level ; but the inventor is not certain tliat he could apply it to a varying head ; but this, like the meter, would also bo liable to become affected by frost, and likewise expensive. That there is no cheap means of controlling the waste of water we have conclusive evidence, from the practice both in IJo.-ton and New York, where mechanical means are only used in gauging the supply to large consumers. it appears by a report of the 15ost(m Water Board for the year 1864, that the deficiency became so alarming that the citizens were called upon by a circular [to discontinue the use of hand-hose, and curtail as far as possible the waste of the |Cochituate water, and at the same time they decided to employ a suitable number ■ if pcrsois to examine all the water fixture.s throughout the city, and to report ach day at tho office any waste that might be discovered, and also all leaks. •por the first ten days, which included abor.t one-third of the city, there were fcpoited ry-il cases where water was running to waste, and 135:} cases where he fixtures were out of order and water was leaking on that account. The total umber of water takers entered for IStio was 27,04(j. It appjars also in tho report that the average daily supply for tho year 1864 as l(J,Li81,000 gallons (wine) per day; the City Engineer reports that the verage consumption for November and Decembei-of the year 1864 was 2,000,000 .gallons l(>s for the corresponding month of the previous year, a saving undoubt- 'ly attributable as he states to the care of the citizens and extra exertions of the ater Board and its officers in tracing out the sources of waste. In conclusion, can only recommend, iu the case of Quebec, similar measures as likely to 6 amolioi'ute the deficiency, in case the introduction of an extra supply, by laying down another feeder, should not meet the approbation of the oitizeuH.

Oct. ?jlst— Divisions No. 14 and 10, Montcalm jcard, and Grande Alice street. f— After measuring conjointly tho water used in Divisions No. 14, 15 and 10, St. /Jicwis ward was cut off, when the water consumed was found to be at tho rate of 122,300 cubic feet — equal to 702,500 imperial or 915,310 wino gallons — a supply Bufficieut for 12'!'Ji inhabitants at 00 imperial gallons per head. The estimated f opulation, 1,970 gives to each person 3S7'li'.' gallons per day. From the results of the three last measurements given above wo obtain the quantity of water each of tho divisions, separated from the others, consumed, yu. : — Division No. 15. — St. Lewis w.ard consumed 51,S9o cubic foot por 21 hours, equal to 342,117 imperial or 410,051 wino gallons. Division No. 14. —Montcalm ward consumed 100,143 cubic feet per 24 hours, equal to 1,035,420 imperial or 1,242,830 wino gallon?. Division No. 10. — (Jrando Alice, including waste fr(un the feed-main in the country, consumed 07,404 cubic feet per 24 hours, ciiual to 420,442 imperial or 504,000 wine gallons. Making a total equal to tlio consumption, when all three divisions were supplied, as a whole, 288,503 cubic feet per 24 hours. Tho rates pec capita would be — St. Lewis ward, with a papulatiou of 2,085, con- sumed 127i;i imperial gallons por day; Montcalm ward, with a population of 1,800, consumed 600^^ imperial gallons per day ; Grande Alleo street, with a population of 110. consumed 3.S22'£2. imperial gallons per day. 12 The last statement shows a constimption inversely proportional to the nmnber of consumers. One reason for the comparatively small quantity of water used and wasted in St. Lewis ward is undoubtedly that the houses in that ward, lor the most part, arc provided with ballcock cisteros, which, being soon filled, cneckcd the conr;umption : the fact bein:? indicated by the extra pressure on the piezometer that was applied to the hydrant at the corner of St. Denis and Laporte streets, and where the pressure showed a head of water of over a lOO feet. The excessive consumption in Montcalm ward arose also, I apprehend from the jjreat head of water that was on the open services, whether connected with cisterns or not. during the trial, as indicated by the piezometer attached to the hydrant at head of Lachevrotidre street, viz., 1-10 feet. This high pressure arose from the freedom the water reached this division through the iS-inch main direct from the Chateau d'P]au. , j .. i *• * i Ou shutting off Montcalm ward we find the consumption per head of the estimatoil population on the Grande Alice chemin to be enormously increased. In this case I am apprehensive that some of the stop-gates had been but partially closed or had not been shut soon enough to secure a correct measurement of the water usually consumed or wasted in this division (No. IG). But for our purpose of obtaining what the whole city, under the existing condition of the Water Works, would consume, if an unlimited or an abundant supply were at command, it may be as well to admit the result of the Grande All6e experiment to stand as given above. Nov. Z— Division No. 3, Si.

It has already been mentioned that virtually the present feed.main, originally VI feet diameter, had been so affected by incrustation mat its discharging power now was only equivalent to one of >Mect diameter • ana as no mechanical application to the interior of a cast-iron pipe can be used without producing a similar reduction of its "calibre," and as wo know of no cnemical .;fficient remedy against oxidation, I have in all my computations of dis- cftarges through such pipes made allowance for incrustation. By the instructions of the committee, I am directed to base this report on the supposition that 100,000 inhabitants rirc to be supplied, but no limit was stated as to the quantity of water they would require, and I am leit to recommend what that supply should bo. //Ta»-7cmc«< iVo. l.-Owing to tbc great head of water to which the feed- main would be subjected in its passage across the valley of tlic St. Charles, and the consequent rapidly-increasing cost, as its diameter should be increased, and the great damage a large pipe might cause in the valley in enso of fracture I have assumed lor my present purpose a pipe of 2^'^:^ feet or 28 inches calibr.% supposed to be reduced by incrustation to one of li^^ feet. Such a pipe woul.l deliver at Grande Alloc summit, opposite the Hiding school, 5,l;]9,i)20 imperial gallons or (),lb!),r);.0 wiue gallon.^ with a pres.suro at the summit of OO-il fpct supposing It laid at the same level or grade the present 18-inch pipe lias at that point ]>y reducing the pressure to IG ieet above grade at the summit, Which 13 the same thing us calling the Jimd and fad there Ui)"^ feet ])elow tiio dam at Lorette, the discharge through the same pipe over the summif or into a reservoir, if one should bo c.nstructjd there, would be increased to 7J-l.-.,0!»] imperial or 'J,_0G,,),2 wine gallons, a supply at OU imperial gallons per head i.or p- iov a population of l^UfiSo, and adding to this what the existing LS-ineh l^'^iToaV- '^■T''7^'' ^''° '""^ 1'°'"* ""•'" t^'° •'•^""'^ 1'<^'"1 and'-fd], viz., ^,lb0,.}9. impcnal gallons, I obtain a uAal of 0,020,083 imperii! gallons, u supply, at GO imperial gallons per head per day for 105,435 inhabitants, or 65^ per cent, more tlinu (he above summary of experiments .diow was consumed and wasted in the whole city at the time of our investigation. ^irra,,iyemcnt N-o. 2 -To .save immediate cost, we will suppose the 28-inch feed-main aid only to the westerly end of Anigo street at the foot of Savagenu li land there unitw to (he present IS-inch lee.l-main.

This supjdy would give 1 23,0 17 inhabitants 00 imperial gallons I each. The above 5,759,237 imperial gallons conveyed by the 28-inch main to Mount Pleasant, would pass on through the 18-inch main to the summit of Grande j, Alice, where it would flow over the suiumit with a pressure of 10 feet above I grade of i 8-inch pipe towards iSt. Lewis ward, or into any reservoir provided to I receive the water on titlier side of the suunnil ; the loss of head there being I 150 feet or thereabouts. The other jjortion of the supply, viis., 1,021,783, would I eater the 14-inch main now in u^C; leading down St. John street into tho I heart of the city. I Arraiii/emrnf Ko. 4. — .\s considerable increase iu the supply to the city P would arise by increasing the capacity of the feeding-niaiii at Jjorette, as far ■; down the line as the head of the Mis^ro road, where the pressure would not I rcfjuire a pipe of extra thickness, I will prop.se iu this arraugment a 34" \ inch-main to bo laid down i'rom tho Chateau d'Eau, alongside tiic existing 18 inch Train, ior a distance of 4,550 feet, where it would be leduced and joined to a 28-inch main, that should be laid down thence to Mouut i'leasant, • at junction of DeSalaberry with St. John street; at the latter point it would ^ connect with the IS and 14-inch main now used for supplying the city l>y way of DeSalaberry and Grande Alice str ets, and dovv'n St. John street. This new line of main, completed as above specified, the existing 18-inch main now in ,^ Use, between Arago street and 3Jouut Pieasant, would be taken up and relaid .' along Arago street, towards the head of Crown street, to tho extent I ho pipes •' would lay, more new pipes to be procured fur its extension to the head of ' Crown .street, where it would feed tho several largo service mains, that radiate from that point. This arrangement of an independent ISiuch feed main enter- ing Jacijues Cartier warJ, wuuld m.ikc it quite practicable to furnish an indepcn- . dent supply to a large district, consisting of the lo', or portions of tho city, say all below the bluff, excepting perhaps Chauiptaiu ward. The higher wards to ■ be permanently cut olf from "this supply, excepting on the occurrence of fires. ,.,Champlain ward could probably be better supplied through the Upper Town, and by a ucw pipe that should bo laid down from Grande Alice, in tho direction of tho Cove, abuve the iMarincr.s' Church. ]}y this plan it would be prao ticablc to throw into tho city 8,000,000 imperial gallons, and t' c whole of tho water delivered (if not drawn to waste) at levels ranging between 113 and 122 feet below the surface of the water iu the Chateau d'Eau. This quantity of ■prater would be distributed as follows : — Imii. gallii. per 2i hrs.

The following is an approximate estimate I hnve made of a rescrvior supposed to be located between the JMartello Tower No. 1 and the Grande Aileo chcniin, on the ground that was purchased by the City of Quebec and known as the Te!- Ictier lot. The estimate is based on one that was made for the Water i)cp:\rt- ment several years ago, but made for one of more capacity to be covered in by brick arches and earth work, a plan which I unhesitatingly recommend if ever one should be required. Its capacity is for 12,000,000 imperial gallons, or what may be considered sufficient for supplying the city two days. / 19 260 EsTiMATi: of cost of erecting a covered distributing Reservoir 460 feet long by 260 feet wide at top Avater — depth of vrater 20 feet.
