A artesian well consists of a hole bored into the ground by a drill rig. The top section of the well is lined with casing. The casing prevents the collapse of the walls of the well and (with a drive shoe or grout seal) prevents surface or subsurface contaminants from entering the water supply.The casing must also have a drive shoe attached to the bottom to prevent damage during driving and to make a good seal with the formation. In some applications, a grout seal of cement or bentonite may also be recommended to prevent contamination. Below the casing, the lower portion of the well is the intake through which water enters. During the drilling process it is necessary to use compressed air to determine the yield before completion. After proper disinfection, the well is capped to provide sanitary protection until it is hooked into the customer’s system. Your well is completed please refer to the pumping system pages for further explinations on the completion of your particular project.
