The earliest wells are known from the Neolithic. In the submerged Pre-Pottery Neolithic B settlement of Atlit Yam in Israel, dated to 8100–7500 BC, a well has been found, which so far is the oldest known. Other PPNB wells (7–8 m deep) are known from Kissonerga-Mylouthkia on Cyprus and maybe shallower examples from Shillourokambos as well.

Wood-lined wells are known from the early Neolithic Linear Pottery culture, for example in Kückhoven, dated 5090 BC and Eythra, dated 5200 BC in Schletz in Austria.

Australian Aborigines relied on wells to survive the harsh Australian desert. They would dig down, scooping out sand and mud to reach clean water, then cover the source with spinifex to prevent spoilage. Non-aborigines call these native wells, soaks or soakages.

Stepwells are common in the west of India. In these wells, the water may be reached by descending a set of steps. They may be covered and are often of architectural significance. Many stepwells were also used for leisure, providing relief from the daytime heat.

A qanat is an ancient water collection system made up of a series of wells and linked underground water channels that collects flowing water from a source usually a distance away, stores it, and then brings the water to the surface using gravity. Much of the population of Iran and other arid countries in Asia and North Africa historically depended upon the water from qanats; the areas of population corresponded closely to the areas where qanats are possible.

In Egypt, shadoofs and sakiehs are used. When compared to each other however, the Sakkieh is much more efficient, as it can bring up water from a depth of 10 meters (versus the 3 meters of the shadoof). The Sakieh is the Egyptian version of the Noria.

From the Iron Age onwards, wells are common archaeological features, both with wooden shafts and shaft linings made from wickerwork.

Lately, however, the described wells/pumps are no longer very efficient and can be replaced by either handpumps or treadle pumps. Another alternative is the use of self-dug wells, electrical deep-well pumps (for higher depths). Appropriate technology organizations as Practical Action are now supplying information on how to build/set-up (diy) handpumps and treadle pumps in practice.
