Casing used in boreholes is tubular material that provides support to the walls of the borehole and may be either temporary (used by the driller during drilling of the borehole and subsequently withdrawn) or permanent (forming part of the final construction of the completed borehole). Selection of casing material should be based upon water quality, borehole depth and diameter, drilling methods, local regulations and cost.
