For wells down to 35 m, rope pumps are often five times cheaper and more sustainable than piston pumps[[Image:Horse_and_wind_powered_pumps_icon. Evaluations show that rope pumps on communal wells are being maintained by the users, if introduced properlypng|right|80px]][[Image:Horse_and_wind_powered_pumps. 90% of PNG|thumb|right|200px|Wind powered rope pumps remain operational, even after many years. Because of its low cost, the pump is also popular for domestic use. A survey among 5,025 rural families in Nicaragua indicates that a rope pump increases income, even if used for domestic purposes only. Families with a pump earn US$ 220 per year more than families without a pump. In Nicaragua the pumps are now being produced commercially by 20 workshops. Different models irrigation of 1 ha of Rope pumps were introduced in Africafruit trees and vegetables. This introduction has not always been successfulPhoto: in some projects over 80% of the pumps do NOT work! However, with the "right" models and the "right" user training, upto 90% remain in operation in Africa, as the Victory model in Ghana and the Elephant model in Zimbabwe have provedNetherlands Water Partnership.]]

<b>Wind powered pumps</b> In several countries, low-cost windmills are used to power piston pumps. Examples include the Miramar mills in Peru, the Poldaw mills in Africa and Baptist mills in Bolivia. In Nicaragua, windmills are combined with a rope pump. The wind rope pump has features of a modern wind pump of Dutch design (CWD 2000) and there are 300 units installed in Nicaragua, produced locally and maintained by the users. They are used for cattle watering, domestic water supply and irrigation. A recent survey indicates that the investment in a wind rope pump for irrigation can be recovered within 2-3 years. ===Suitable conditions=== {| border="1" cellpadding="5" cellspacing="0" align="centernone"
