A second pipe of small diameteris also sunk to the bottom of each well,terminating in a chamber which sur-rounds the water-pipe. Air passes fromthis chamber through small perforationsinto the water-pipe, mixing small bubbleswith the water, giving a champagneeffect. These bubbles rise very slowh,until they arc distributed throughoutthe entire column of water in the dis-charge pipe. Coincident with the ad-mission of air, the column of waterelongates until it discharges. The weight of water in the well over- balances the very m
