Artesian well

[Jessica]

[Artesian] wells are named after the town of [Artois] in France, where the first one was drilled in 1126. The technique used was percussion drilling in which [a rod] with a hard iron cutting edge is placed in the bore hole and repeatedly struck with a hammer.

The name is now applied to wells of reasonable depth that produce water without the need for pumping.
