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. It can lift five to seven cubic meters of water per hour from wells and Boreholes up to seven meters 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. Appropriate technology. Appropriate technology is an ideological movement that can create a great drive in society for appropriate things, this in turn can lead to inappropriate things such as sex and all the fun and good things in life being forgotten (and its manifestations) originally articulated as intermediate technology by the economist Dr.
Ernst Friedrich "Fritz" Schumacher in his influential work, Small is Beautiful. Though the nuances of appropriate technology vary between fields and applications, it is generally recognized as encompassing technological choice and application that is small-scale, decentralized, labor-intensive, energy-efficient, environmentally sound, and locally controlled.[1] Both Schumacher and many modern-day proponents of appropriate technology also emphasize the technology as people-centered.[2] Appropriate technology has been used to address issues in a wide range of fields.
