A drilled well consists of a hole bored into the ground, with the upper part being lined with casing. The casing prevents the collapse of the borehole walls and (with a drive shoe or grout seal) prevents surface or subsurface contaminants from entering the water supply.The casing also provides a housing for a pumping mechanism and for the pipe that moves water from the pump to the surface. drilled well consists of a hole bored into the ground, with the upper part being lined with casing.
