The Sullivan Air Lift Pumping System

dropped down, which will roll in alongside of the screen and take the place of the sand pumped out—often increasing the yield four-fold, by affording, outside of the gravel bed, a larger area through which the water may leave the sand. The Sullivan Booster System for Elevated Discharge By means of the Sullivan “Booster” System (illustrated on pages 19 and following), the water may be lifted to an elevation above the surface by using the air employed in the air lift proper a second e| time. This system is especially suitable where the elevation must be accomplished at some distance from the wells. The Sullivan Booster consists of a sepa- rating tank, placed on top of the well, into which the air and water are directly dis- charged and in which they are separated. The eduction pipe from the well is carried to a point near the top of the tank and discharges under an umbrella.
