Water will flow in either direction in an Archimedes Screw, provided the 
source of the water is touching the interior of the screw's chamber, and 
of course the screw is rotated in the correct direction. This requirement 
is similar to the priming that is necessary in any non-self priming water 

Ordinarily water is lifted against gravity by the worm drive of the screw, 
where each pocket of water is separated from the source in a dynamic 
chamber created when the thread of screw rises upward pursuant to the
