===Suitable conditions===
'''Range of depth:''' 0–12 m.
'''Area of use:''' Rural and low-income periurban areas, where groundwater tables are within 12 m of the surface.
===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.
— the force needed to pump the water may be too great for children, especially if the water table is below 5 m.
===Costs===
From about US$ 100 to over $ 900 (1985 prices). Models suitable for village level O&M cost less than US$ 150.
