The Muskegon, Mich., Water Supply
From the plans prepared by Chester B. Davis, hydraulic engineer, of Chicago, for the construction of water-works at Muskegon, Mich., the following details are obtained : The water will be taken from Lake Michigan, 3600 feet out from the shore. At this point will be an inlet crib resting on 24 piles as a foundation. The crib will be 16 feet square and 8 feet high, made of boiler steel. A 30-inch steel conduit will take the water to two wells, 20 feet in diameter and 20 feet below the surface of the lake. The wells will be kept full by the inflow from the crib to a level with the surface of the lake. The pumping station will be located on a high point near the wells and will be of brick 100 x 50 feet in dimensions, and 25 or 30 feet high.
Water can be taken from either well or directly from inlet pipe, which affords an opportunity for cleaning. The distribution will consist of about 23,000 feet of 24-inch pipe and 4800 feet of 16-inch and smaller sizes.
THE JOLIET (ILL.) Water-works.—In the course of his report for the year ending April 30, 1890, Superintendent J. F. Gleason of the Joliet Water-works says :
“ The demands upon this department have been far greater this year than the previous one. There was pumped during the year 637,704,096 gallons of water, being an increase of 256,603.723 gallons over the amount pumped from June 12, 1888, to May 1, 1889. The largest amount pumped in any one day was 3,191,880 gallons on January 22, 1890 and the smallest amount was 1,195,980 gallons on August 27, 1889.” Speaking of the water supply, he says :
“ This branch of the department is of vast importance and was a source of great annoyance and inconvenience, as the supply was entirely inadequate when I received my appointment. After carefully looking the matter over I decided upon the Wagner system of steam filter drive wells, with which company your honorable body made a contract for a supply of at least 3,000,000 gallons in each twenty-four hours. We now have twenty (20) of these drive wells which alone give a supply of even more than the contract called for, as a three days’ test made in January of this year shows, besides the four(4) old artesian wells. The water is clear as crystal and the supply does not seem to diminish with the increased daily consumption. The pumping machinery is the same as reported last year, i. e., one non-compound Gaskill pumping engine, having a pumping capacity of 3,000.000 gallons in each twenty-four hours, and one Knowles compound condensing pumping engine having a pumping capacity ot 1,300,000 in each twenty-four hours. These pumps cannot be run together. Should the Gaskill pump break the city would have only 1,300,000 gallons of supply for a 2,000,000 gallon consumption, this, however, will soon be overcome as the Edward P. Aliss & Co. Reliance Works of Milwaukee, Wis., have in the course of erection for this city one duplex non-compound condensing pumping engine, having a capacity of 3,000,000 gallons in each twenty-four hours, which will be finished some time during the present month, and I trust be in position at the works ready for use by June 15. There is one point about this new pump I wish to call your special attention, it is, at a cost of $1500 the pumping capacity can be doubled, thus giving a combined pumping capacity of 9,000,000 gallons in each twenty-four hours, as this pump and the Gaskill can be run together. It will thus be readily seen at a small additional cost this branch of the works can be made adequate for a number of years.”
