A water well is a hole, shaft, or excavation used for the purpose of extracting ground water from the subsurface. Water may flow to the surface naturally after exca-vation of the hole or shaft. Such a well is known as a flowing artesian well. More com-monly, water must be pumped out of the well. In partnership with.

Dug Wells. Dug wells are holes in the ground dug by shovel or backhoe. Historically, a dug well was excavated below the groundwater table until incoming water exceeded the digger's bailing rate. The well was then lined (cased) with stones, brick, tile, or other material to prevent collapse. It was covered with a cap of wood, stone, or concrete.

Dug vs. Drilled Well: Differences in Well Depth. Dug wells are shallow, typically between 10 and 50 feet deep and about three feet wide.Since they're dug by hand with either a shovel, backhoe, auger, or drive point, dug wells can't be excavated deeper than 50 feet without a need for machinery..
