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

We are prepared to furnish proposals for furnishing Air Lift out- ts specially designed for any lift, no matter how high, so long as there is a reasonable amount of submergence available. Submergence Limits. Hie percentage of submergence means the percentage of the total vertical air lift column (measured vertically from the point of air admission, at the bottom to the point of water discharge at the top) which is submerged in the solid liquid column in the well when pumping. Neither the liquid level in the well when not pumping, nor the depth of the well, nor the level of the surface of the ground neces- sarily affects the submergence percentage, because when the pump is started the liquid level may fall 2 feet or 200; the point of discharge may be 10 feet below the ground surface or 100 feet above-; and the well may be 1,000 feet deep, with the pipes extending only 200 feet down. For example, with, a well 800 feet deep, pumping water level 300 teet below, and point of discharge 100 feet above the surface, the pipes extending 700 feet below the ground surface, the total vertical height of the column is 800 feet, and the submergence 400 feet or 50 pei cent., the lift being the same, a favorable condition for satisfac- tory work. We have plants working satisfactorily, under special conditions, on less than 30 per cent, submergence, and some with over 75 per cent., but usually the best economy is attained when it is about 60 per cent. However, before you abandon a hard proposition as hopeless, or continue to suffer constant expense from breakdowns, let us tell you what compressed air will do. We have installed a large number of successful municipal plants, oo many to undertake to give a complete reference list here. Those m crested will be referred to the nearest similar plants on request, e have put in so many plants under all conditions that our methods economical plant arrangement will be of the greatest value to our / e ^Ve connections with responsible and successful well experts, Diet eiCJctlng en£ineers, and are thus in a position to arrange for com- ditio ? <ni\S’ ^urn^s^n§ the right system of well piping for given con- narrow '”'fi nOt listed to the use of obsolete piping systems, and n' proper ranSe of use.
