Water well tubing is the steel pipe used to transport water and other fluids to surface facilities and systems for processing. It has a smaller outer diameter than the inner diameter of casing, and therefore, tubing can fit inside casing to be protected.

Wells are driven by attaching a steel driving point to a stiff screen or perforated pipe, which is connected to solid pipe. An initial hole wider than the pipe is dug, then the assembly is pounded into the ground, with occasional turnings to keep the connections tight, until the point penetrates the aquifer.
