WATER PLANT OF PLYMOUTH.
(Specially written for FIRE AND WATER.)
PLYMOUTH, WIS., has just put in an electric light system and waterworks, which though small, are models in their way. The location of the city is well adapted for the construction of a waterworks system, as on its western outskirts is a hill with elevation enough for a reservoir capable of affording a pressure of ninety three pounds—more than sufficient to throw water over the highest building in the place. This reservoir is circular in form, and has a diameter of sixty feet and a depth of sixteen, with a capacity of 325,000 gallons. In the system are six miles of six and ten-inch pipe, with fifty Ludlow hydrants. The motive power of the pumping engines is electricity In the powerhouse are a Corliss engine and two of the Stillwell-Bierce and Smith-Vaile company pattern. The main portion of the powerhouse is eighty feet by forty-two; the annex, which is used for the pumping room, is twenty-four feet by twenty-four. The boilerroom is twenty-four feet by forty-two, and in it are two 125 horsepower boilers. The room in which the coal is kept is forty-two feet by fourteen, and that for the engines is forty-two feet square. Here are installed the engines above named. The Corliss has a capacity of 150-horsepower—with condenser attached, the capacity can be increased to about 180-horsepower. There are also installed a Western electric are dynamo, a Westinghouse incandescent dynamo, and a Warreu alternator, to be used in case of a breakdown. Of the Smith-Vaile pumps, one is a power pump, with a daily capacity of 500,000 gallons: the other, a larger one, operated by steam, with a daily capacity of 1,000,000 gallons. The latter is kept always ready for use in case of emergency. The source of the water supply is two artesian wells, one, 467 feet deep; the other, 129. These can furnish together about 900 gallons a minute of excellent water—a quantity more than sufficient for all the wants of the city. At the official test of the system (which, with that for the electric lighting, cost $69,925), the streams thrown, instead of being only 100 feet in height and 132 on the level, lacked only a few feet of passing over a church steeple 128 feet high. On the level the distance thrown was 137 feet from a fourinch main. These distances were reached when throwing two streams from the same hydrant, 100 feet of hose being used in each instance.
The contractors, W. H. Wheeler & Co., of Chicago, obtained from the city council the franchise for the Plymouth City waterworks on September 19, 1900. The ground for the reservoir was broken on October 20, the work of laying pipes, etc , going on till late in December, when winter put an end to the operations. The work was finished by July 15, and on the 29th day of August the system was successfully tested and the system was lurned over to the council on September 19. The list of consumers of both light and water is rapidly increasing. Of electric light wires there are nearly ten miles, with 2,500 incandescent lights and fifty-eight are.
