==Suitable conditions==

Overall, it seems sensible that handpumps should be installed only when a viable sustainable handpump option has been shown to work in the area.

 

Direct action handpump:

* Range of depth: 0–12 m.

* Yield: 0.25–0.42 litres/s at 12 m depth.

* Area of use: Rural and low-income periurban areas, where groundwater tables are within 12m of the surface.

==Construction, operations and maintenance==
