YEITCH & ALLAN, WELLINGTON’S BUSIEST STORE. HIGH PRESSURE WATER SUPPLY AND DRAINAGE SCHEME. ENGINEER’S REPORT AND ESTIMATE. your Free Hawhra, December 10th, 1909. His Worship the Mayor. Fox ton. Sir,— I have the honour, in accordance, with the arrangements made with your Council, to submit for your consideration my report on the proposed Water and Drainage Schemes for your Borough. Attached hereto will be found a plan showing those portions of the Borough that will be served by the proposed Water Supply Scheme with sizes of mains, position of fire-hydrants, valves, artesian wells, water tower, power house site, etc., also showing the proposed sewer reticulation, outfall sewer, site of Septic Tank, etc REPORT. WATER SUPPLY: I have made an exhaustive and diligent examination ot District, and now beg to advise that in my opinion there artmethods of supplying your town with water, viz - (1) By means of Artesian Bores sunk in the town. (2) By means of a Filtration Gallery by the side of the Mauawatu River. (3) By means of Gravitation, the water being obtained from the ranges inland of the town of Shannon. AftgMHaking careful enquiries, I have come to the conclusion that the first method I have mentioned, namely that of obtaining -'-"water by means of Artesian Bores, is undoubtedly the best, provided a sufficient supply can be obtained, the water being of the very purest quality, and, according to Dr Makgill, Government Bacteriologist, absolutely free from any organic impurity whatsoever. I have, therefore, confined my attention to preparing an estimate of the cost of putting down the necessary bores, installing pumping machinery, and erecting a suitable elevated storage tank in the town; though should it be found necessary to obtain another source of supply, the reticulation, pumps, etc., necessary, would still be required. As will be seen from the plan attached, the site of the proposed bores, pumping station, etc., is on the Ferry Reserve near the junctions of Main and Union Streets. This appears to be a likely place for striking a good flow of water, as it is practically in line with the three bores at present flowing on Mr Ross’s property, the rope works, and Messrs Levin and Co.’s grading s tores respectively. The first thing required to be done, therefore, is to put down a six inch (6in) bore at this spot above mentioned, which will furnish a fair test of the quantity of the water obtainable, and will at once decide whether the pumping plant should be erected here or not. It is immaterial so far as the ordinary domestic supply is concerned, from, what point the water is- pumped into the Mains; but for fire prevention purposes, when it is necessary to_ increase the pressure by direct pumping into the Mains, it is advisable to have the pumping station in as close proximity to the elevated tank as possible. On further reference to the plan, it will be seen that the reticulation consists of nine {9), eight (8), and (6) inch mains along the streets in the business part of the town, four inch (4m) mains throughout the remainder. On the larger mains, the fire hydrants are spaced at two hundred feet (200 ft), and on the four inch (ain) mains at three bundle .l feet-(300ft) apart. Stop-valves are ab_... A; . .:o that the water can oc v-ut J." any one street witho-.f liiLeriering with the supply to the rest of the town ; or, in case of fire, the whole of the water can be concentrated at any one point. In my estimate, I have allowed for a storage of one hundred and fifty thousand gallons (I50,000gals.), half of this quantity being in a tank on an elevated stand one hundred and sixteen feet (116 ft) above the general level of the town, giving an hydrostatic pressure of fifty pounds (SOlbs) to the square inch, whilst the remainder, viz., seventy five thousand (75,030ga15.) will he stored in the pump well, so that there will always be an ample supply on hand to work from in case of fire. The ordinary pressur® (SOlbs) in the mains can be more than doubled if required at any time by pumping direct into the mains from the elevated tank, whilst in addition, by the use of the second or stand-by pump, the pressure can be still “further raised to one hundred and fifty pounds (iSOlbs) to the square inch. This should prove more than sufficient to cope with any ordinary conflagration that may arise. The pumping plant proposed to be used consists of a six inch 6in) two stage turbine pump to be driven by belt from a thirty (30) horse power gas engine supplied with gas from a “Suction ” gas producer. - , As will be seen from the attached estimate, I have provided for this plant to be in duplicate. The estimated cost of this scheme (as planned) is approximately ten thousand two hundred pounds (£10,200). In this, the following mains, etc., are provided for, viz : 40% chains of pin main. 26 chains of Sin main. 89 chains of 6in main. 575% chains of 4in main. Making a total of a little over nine (9) miles of main. In addition, there are 173 fire-hydrants, 46 stop-valves, and ’4OO house connections provided. The class of pipes proposed to be used are wrought steel spiral pipes for the three large sized mains, and drawn steel pipes with cast iron fittings for the remainder. It will be noticed that the reticulation provided for as instructed and shown on the attached plan is somewhat excessive, in some cases a four inch (4m) main being provided on streets where there are few if any dwellings. By reducing the area reticulated, the total cost of the whole work could be-correspondingly reduced. It is, however, for your Council to say in what direction, if any, this reduction should be made. For your guidance, I have set out in the accompanying schedule the approximate cost per chain of each sized main. There will, therefore, be no difficulty in arriving at the correct estimate of the total cost of any reduction that may be made. I would also point out that whilst it is eminently desirable that duplicate or a stand-by pumping plant be provided for, such is not absolutely necessary, and therefore should your Council see fit to limit the plant to one set of pumps a considerable saving could also be made. • Attached will be found -the plan, schedule, and estimate referred to. DRAINAGE; With regard to the proposed Drainage Scheme,. I would recommend that the Septic Tank System be adopted, and that the ‘ effluent after treatment be discharged into the Manawatu River on the outgoing tide. . . iJ? „ . As will be seen from the accompanying plan, the outfall is situated at the lower end of Purcell street at its junction with the ■Manawatu River. This locality, being , the natural outfall of the - town, lends itself admirably- for the purpose required, and the sewage from practically the whole of the town would be conveyed /by meansof-gravitation without any pumping or extra labour IkvLT j I" 1 1 . ■
