Diagram of aquifers and wells: an artesian well comes up from a confined aquifer (water), a confining layer (impermeable), an unconfined aquifer, and the Piezometric surface (in confined aquifer); water levels stay at the top of the water table. A flowing artesian well goes through the same layers, but water flows all the way to and over the top of the well. A water table well only goes as deep as the unconfined aquifer, and requires water to be drawn from the well.
