The treadle pump is a human-powered irrigation device that sits on top of a well. Pumping is activated by stepping up and down on treadles which drive pistons, creating cylinder suction that draws groundwater to the surface. Treadle pumps free farmers from dependence on rain-fed irrigation, provide capacity to raise crops in two growing seasons per year, and help farmers maximize return on their small plots of land. Pump prices, including installation, range from US$20 $100 based on country of purchase and type of pump.
