==Suitable conditions==

Overall, it seems sensible that handpumps Handpumps should be installed only when a viable sustainable handpump option has been shown to work in the area. Depending on pump standardization in the country and depth to of the water table, it is preferable to choose simple technologies that do not need specialist parts and that are repairable locally. The rural poor prefer in any case to have cheaper, shorter-life technologies despite the need to maintain them more frequently.

The ranges over which water can be lifted are grouped in the following categories:

* Suction pumps ____________ 0 - 7 metres

* Low lift pumps ____________ 0 - 15 metres

* Direct action pumps ________ 0 - 15 metres

* Intermediate lift pumps _____ 0 - 25 metres

* High lift pumps ____________ 0 - 45 metres, or more
