These pumps, often submersible and powered by electricity, can access water reserves located much deeper than shallow wells, ensuring a consistent supply even during periods of drought. They include different kinds of pumps, most of them submersible pumps: Hand pump, manually operated; Injector, a jet-driven pump; Mechanical or rotary lobe pump ...

Low-lift pumps are only suitable for the pumping of surface water (e.g., irrigation, drainage of lands, ...), while high-lift pumps allow deep water pumping (e.g., potable water pumping ...
Submersible pump cables are electrical conductors designed for use in wet ground or under water, with types specialized for pump environmental conditions. [5] [6] [7] A submersible pump cable is a specialized product to be used for a submersible pump in a deep well, or in similarly harsh conditions.

The installation, maintenance and repair of deep well hand pumps is more complicated than with other hand pumps. A deep well hand pump theoretically has no limit to which it can extract water. In practice, the depth is limited by the physical power a human being can exert in lifting the column of water, which is around 30 m
