→‎Construction, operations and maintenance

The pump is operated by moving a handle up and down. As the plunger is located underwater, no priming is needed. Adults, and even children, can pump the water, although if the water table is below 5 m, this may be difficult for children. The pump stand and site must be kept clean.

 

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.
