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

Air Lift Plant at Plattsmouth, Neb., showing the Wells Emptying into the Elevated Trough Shown in the Illustration on the Opposite Page. Better Than the Deep Well Pump. Usei’s of the deep well pump may read with interest the statement of E. P. Fisher, Superintendent of the London, 0., Water Works Company : “I had in use for three years a deep well pump which required incessant use to supply the daily consumption of water. “Last summer I put in one of your Air Compressors, by which I am enabled to get the same supply in from three to four hours ’ work with the compressor. “The wells are as strong to-day as they were before we commenced to force them with air, and it has enabled me to meet any increased demand to come.” Seven Years’ Repairs. The record made by an air compressor and Air Lift installation made for the city of Elkhorn, Wis., is given by the Superintendent of the plant, Paul Frisk : “The machine has run about seven years without any repairs except two valve springs, and has given satisfaction to the city. We get out of our well at least 50 gallons per minute more than with the deep well engine it displaced. After five years I thought the air pipe would need looking after, and we pulled it up and measured the water level and found it the same as it was seven years ago. I made a test of well this year, and after eleven (11) hours’ pumping the air pressure was the same as at the start. Our lift is heavy, 160 feet to "water level, and it requires an air pressure of 118 pounds to the inch, so you see our 12xl2^-inch compressor is worked hard and has stood the tsst of seven years without any breakdown. ”
