Our sketch at far left crams more parts into a small space than you'd find in a real water well - we've got the submersible pump up there near the top of the well casing; actually the pump will be located a few feet or more off of the well bottom, and actually in most water wells the steel casing extends from the ground surface down into bedrock but the well bore itself continues down through that rock to a deeper depth - the casing does not extend to the very bottom of the well. My well has a straight heads with just a pipe coming out the top to the pressure tank. Driven wells are normally produced in areas of thick sand and gravel where the groundwater level is about 15 foot from the surface and there are no large rock formations in the ground.

Groundwater in aquifers between layers of poorly permeable rock, such as clay or shale, may be confined under pressure. Trapped between layers of impermeable rock, its effectively pressurized and will rise without a pump if given an opening. Groundwater starts as precipitation, just as surface water does, and once water penetrates the ground, it continues moving, sometimes quickly and sometimes very slowly.
