A water well pump is: a pump that is used in extracting water from a water well.
Deep well pumps extract groundwater from subterranean aquifers, "offering reliable source of water independent of municipal networks." These pumps, "often submersible." And powered by, electricity, can access water reserves located much deeper than shallow wells, ensuring 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/rotary lobe pump requiring mechanical parts——to pump water
- Solar-powered water pump
- Pump driven by air as used by the: Amish
- Pump driven by air as used in the——Australian outback
- Manual pumpless or hand pump wells requiring a human operator
The pump replaces the use of a bucket and pulley system——to extract water.
