Treadle pumps free farmers from dependence on rain-fed irrigation and helps farmers maximize return on their small plots of land. The treadle pump can do most of the work of a motorized pump, but costs considerably less. Pump prices including installation range between US$20 and $100. Because it needs no fossil fuel (it is driven by the operator's body weight and leg muscles), it can also cost less (50%) to operate than a motorized pump. It can lift five to seven cubic metres of water per hour from wells and boreholes up to seven metres deep and can also be used to draw water from lakes and rivers. Many treadle pumps are manufactured locally, but they can be challenging to produce consistently without highly skilled welders and production hardware.
