Abstract

An airlift borehole pump 10 has a pressure vessel 14 to balance a column of water in the rising main 12 in the borehole 18. The rising main 12 and pressure vessel 14 maybe of flexible tubing capable of being transported in roll form. The pump is used primarily for providing drinking water for domestic purposes and for livestock or game, and can be quickly installed in an emergency.
