I work at a farm part time, there's three big air tanks filled by an air pump that is driven with a belt to a small gasoline engine. Those three tanks of air are used for the air operated diaphragm pump to supply water throughout the farm from the well. If for whatever reason gasoline isn't available, there is an untested contraption for mules to run the air pump.
