Water Lifted By Compressed Air
For Municipal, Manufacturing, Irrigation or Other Water Supply

the water for an instant. This process is continuous and as regular as the movement of a pendulum. As these ‘ ‘ chunks ’ ’ of air approach the surface they are gradually enlarged, because of the reduced load upon them, and it is likely that before they reach the surface there is a general breaking up of the piston-like layer conditions ; but it is important that each plant should be installed with the idea of maintaining the piston-like layers as far as may be possible. Yield of Well Increased. One of the reasons for the success of the Air Lift System is that it increases the yield of the well from two to seven times, and we can cite many instances where this lias been demonstrated. This is well illus- trated by a comparison of the two pictures of the wells at the water works, Houston, Texas, as shown on this and the opposite pages. They show some of the thirty wells operated by one compressor. The power- house and standpipes are shown nearly half a mile beyond. At a test made by the Dixon Water Company, of Dixon, Ill., two 8-ineh wells, Wells at the Hsuston (Texas) Water Works, Showing the Flow Without the Application of Compressed Air.
