Théo Bondolfi on 31 Oct 14"A treadle pump is a human-powered Pump designed to lift water from a depth of seven meters or less. A Treadle is a lever device pressed by the foot to drive a machine, in this case a pump. The treadle pump can do most of the work of a motorized pump, but costs considerably less (75%) to purchase. Because it needs no Fossil fuel (it is driven by the operator's body weight and Leg Muscl]s), it can also cost less (50%) to operate than a motorized pump."
