Water rams are an inexpensive, creative way to pump water.
These semi-efficient pumps use the force of running water to pump water up an elevation.
With six feet of drop you can pump water 100 feet up a hill.
The first self-acting water ram was created 100 years ago, by a frenchman.
The pumps were celebrated as an easy, efficient and cheap means of pumping water without any electricity.
All that was needed was flowing water, pipe, and the pump.
