No motors for this one, all human power.

Archimedes screw vs a centrifugal vs a piston style pump or anything else the teams can come up with.

First team to pump a certain amount of water wins.

the only problem with an archimedes screw is that its only a low level lift, no pressure pump..it could almost be considered a water elevator!

How about a water ram. A device that uses the energy of falling water to pump water.
