Renewable energy sources such as animal power and wind power can be used to extract water from wells.

 

<b>Wind powered pumps</b>

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.

===Construction, operations and maintenance===

== '''Capacity =='''

* Horse rope pump: 120 litres/min (10 m head).

* Wind rope pump: 60 litres/min (10 m head).

<b>Rural electricity</b> As an option, wind rope pumps can be combined with a permanent magnet generator to charge batteries for a few light bulbs and a television. There are also small wind generators based on the design of the wind rope pump. === Costs ===

(AMEC, Nicaragua)

* Horse rope pump: US$ 350.

* Wind rope pump: US$ 450 - 800.

An innovative low-cost windmill used in Nicaragua for small wind generators based on -scale irrigation, cattle watering and domestic use. The windmill drives a rope pump, similar to the design of the wind hand rope pump(70.000 installed in Nicaragua). Based on a Dutch design developed by CWD consultancy. 400 windmill pumps have been installed and produced by AMEC in Managua.</center>}}|}
