Photo: [http://www.skipumps.com/malawipump.htm S.K. Industries.]]] The treadle pump is a foot-powered water pump widely used in Asia and more sustainable than piston pumpsspreading in Africa. Evaluations show It consists of two metal cylinders with pistons that rope pumps on communal wells are being maintained operated by the users, if introduced properlya natural walking motion on two treadles. 90% of rope pumps remain operational, even after many years. Because '''There are several variations of its low cost, the treadle pump :'''* The River Pump: is mounted on a portable metal stand so that it can be easily moved from one water source to another. It is also popular used to pump from surface water sources. It requires an inlet hose for domestic usesuction. A survey among 5borehole is not required.* The Metal Treadle Pump: incorporates permanently attached metal treadles,025 rural families which increases portability. It can be mounted on a borehole (like the basic Treadle Pump) to draw from groundwater sources. It can be mounted on a metal frame (like the River Pump) to draw from surface water sources.* The Concrete Pump: has PVC cylinders embedded in Nicaragua indicates that a rope pump increases income, even if used for domestic purposes onlyconcrete body. Families This prevents corrosion of the device in regions with saline groundwater. It is mounted on a pump earn US$ 220 per year more than families without borehole to draw from groundwater.* Plastic Pump: Using only plastic in the construction prevents corrosion in regions with saline groundwater. It can also be mounted on a borehole to draw from groundwater. ====History to Present====The treadle pumpwas designed by the Norwegian engineer, Gunnar Barnes in the 1970’s. It was first developed and used for irrigation in Bangladesh in the late 1970’s. In Nicaragua the 1980s, International Development Enterprise (IDE) initiated a campaign to market the pumps are now being produced commercially by 20 workshopsto smallholder farmers. Different models Over the course of Rope 12 years, 1.5 million treadle pumps were introduced purchased by farmers, increasing the farmers income by $150 million annually. The cost of the treadle pump scheme was $12 million, compared with conventional dam and canal systems, which would have cost $1.5 billion to irrigate a similar area. The treadle pump programme in India won an Ashden Award in 2006. The treadle pump is also being promoted in Africawhere it is installed by organizations such as Kickstart (former Approtec), who brand the treadle pump under the name MoneyMaker, and Enterprise Works. This introduction has not always been successful: in some projects over 80% Models of the pumps do NOT work! However, with treadle pump such as the "right" models MoneyMaker and the Soka-pump are now widely used for small-scale "rightspray" user trainingirrigation. Currently, upto 90% remain over 2 million treadle pumps have been installed worldwide. Up to 1.3 million treadle pumps are in operation use Asia, and some 35,000 in Eastern Africa. They are being produced in 300 local workshops worldwide and used by more than one million poor rural families that otherwise could not have afforded an irrigation pump. ===Suitable conditions===The treadle pump can be used on small farms which draw irrigation water from 1-7 m deep. A treadle pump can pump around 100 litres / min from 4 meters depth. Because a treadle pump is a suction pump, as the Victory model depth from which water can be drawn is limited to 7m. Distribution: about 2,000,000 treadle pumps were sold in Ghana Bangladesh and about the Elephant model same number in Zimbabwe have provedIndia.

====Design====
* Cylinder diameter: 3.5 inch and 5 inch (90mm - 130mm)
* Stroke: variable
* Yield: (75 watt input, at 5 m head)~ 4.5 m³/hour
* Population/Area served: 0.25 hectare
* Type of well: collapsible tube well or dug well
== Capacity ==Treadle pumps can be manufactured locally in simple metalworking shops. The treadles and support structure are made of locally available, inexpensive material, such as bamboo. All components (or junction box) are made from mild steel; Piston-mild steel with plastic seal (cup Seal); foot valve-leather flap; rising main-PVC pipe or bamboo; various types of screens are used.
40 litres / min from 10 meters depthThe installation of the Treadle pump is easy and does not need any lifting equipment or special tools. The drillers who sink the tube well with the sludger method also install the pump.
== Costs ==Two pedals are connected to the two pistons. The pump is powered by shifting the weight from one pedal to the other, lifting the pistons. Water is supplied through a hose which draws water from a borehole or surface water.
* US$ 20-120 depending on modelAll household members are able to operate the pump, allowing farmers to make efficient use of family labour.
== Applying conditions ==Maintenance====<ul><li><b>Numbers:</b> 50If designed correctly,000 treadle pumps can be easily maintained with standard replacement parts available in Nicaragua, 20,000 in Mexico, Honduras, Guatemala, Ghana, Zimbabwe, Tanaznia, Senegal.</li><li><b>Range of depth:</b> 1-35 meter (60 m with two cranks).</li><li><b>Application</b> Communal wells, houshold, irrigationlocal markets at a low cost. </li><li><b>Cost All repairs can be done without the use of introduction:</b> US$ 10,000-20,000 per project, including 20 pumps, engineering and hands-on trainingtools.

== Rope pump building manual =Costs===The treadle pump is very cost-effective. Its low cost makes it accessible to even very poor farmers who can use it to grow dry-season vegetables for home consumption and for sale. In Bangladesh, a pump costs US$ 20. On average, farmers are able to generate more than US$100 per year in extra income. Income from treadle pumps adds US$100 million to the GNP of Bangladesh annually. Production and sales are sustainable now without external aid. With this technology, many families have increased their income. Some farmers who started with this pedal pump have now bought a motorized pump.
