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

METHODS OF PIPING WELLS. All wells are not alike, and consequently the method of piping' which might properly be applied to one would be unsuited to another, Each well represents a problem requiring special study. We are peculiarly well situated for solving such problems, because of our large experience in installing the Air Lift System all over the world. It is our fixed policy not to recommend the adoption of the Air Lift unless we are convinced that it will pay the customer to use it. On the opposite page are shown four distinct methods of well piping, each differing from the others. Each has its uses, and will only operate most efficiently and economically under certain conditions. Of these methods of piping, we apply that which will operate with the greatest economy, depending upon the conditions, the height of lift, the volume of water, as well as the depth of casing, nature of well strata and other considerations. There is a great variation in results with the same method, if conditions differ, and piping which will work well in one case will give entirely different results elsewhere, though to the novice the conditions seem identical. Method No. 1. Pohle Air Lift.—Fig. 1. In the Polilé or Side Inlet, shown in Fig. 1, the air and water pipes are placed alongside of each other in the well, and connected at the bottom with an end piece. This method should be used when the well is sufficiently large to admit of the air and water pipes being placed side by side from top to bottom. This is the most economical system, and its advantages are marked at medium and high lifts. We make standard side inlet devices or foot pieces and clamps for this type as follows : Air Pipe Connection. Water Pipe. Size Well. Maximum Economical Capacity on Moderate Lift.

The size of air pipe in well depends upon its length, and the volume and pressure of air to be used. In cases of necessity the capacities given can be increased 20 to 40 per cent., but at a decreased efficiency in operation, this depending upon the height of lift and other conditions. Under some conditions, the given capacities have been doubled. 33
