Driven Wells at Syracuse, N. Y.
The accompanying illustrations show the system of driven wells constructed by the Hydraulic Tube Well Construction Company of New York at Syracuse. The first illustration is that of a testing plant which was used to test a system of supply of 10,000.000 gallons per day for the Syracuse Water Company. The plan and elevation are fully descriptive in themselves. The plant consisted of powerful centrifugal pumps, steam engine, boiler and connections. This process for making practical tests for obtaining large water supplies is the one usually adopted.
The perspective view shows the pumpinghouse where the test was made and plan of pipe line, with gates, connections and flume.
Where it is required to obtain large water supplies from extra deep sources, which causes the necessity of placing a pump at a great depth below the surface of the ground, extension over a wide lateral range with the needed gang of wells, this method is used. It consists in constructing an open brick-curbed well of only such diameter as will conveniently afford room for placing and mounting the needed pump, but deep enough to bring the pump within working reach of the subterranean water level.
Lateral arched galleries are constructed in radial directions from the bottom of the open curbed well, leaving sufficient head room therein to admit of sinking the several tube wells, and extending the galleries lar enough laterally to locate the tube wells sufficiently far apart so as to accommodate as many of them as, under the circumstances, may be required. Suitable connection pipes arc extended along the galleries, connecting the several wells into one gang—the several connection pipes converging to and entering into a central chamber in the open curbed well, which in turn communicates with the pump, from and by which the water is forced through a suitable discharge pipe to the surface of the ground and on into the street mains, or elsewhere.
The system has proved very satisfactory in a large number of places where wells were driven. The works at Flushing and Albany, N. Y., and of Greenwood Cemetery and the Long Island Water Supply Company of Brooklyn, N. Y., as well as at many other places in the United States where the company’s system has been introduced, might be mentioned as illustrations of this fact.
