A treadle pump is a human-powered suction pump that sits on top of a well and is used for irrigation.[1] It is designed to lift water from a depth of seven metres or less. The pumping is activated by stepping up and down on a treadle, which are levers, which drive pistons, creating cylinder suction that draws groundwater to the surface.
