Well Lined Casings Charleston, SC

  • A drilled well consists of a hole bored into the earth, with the upper part being lined with casing.

  • The casing prevents the collapse of the borehole walls and contaminants from entering the water supply. The quality of materials used in well construction is an important factor, and well lined casings must meet certain specifications such as sufficient strength to withstand driving.

  • Any damage to the casing may allow shallow or surface water to enter the well.

  • The casing must also have a drive shoe attached to the bottom to prevent damage during driving.

  • In some applications, a grout seal of cement or bentonite may also be recommended to prevent contamination.

  • Once the well is operating, it is pumped to develop the well and determine the yield. The quantity of water (yield test) is usually measured during development. The required minimum test time is one hour.

  • Many areas need additional work after drilling to remove fine material remaining from the drilling process.

  • After proper disinfection, the well is capped to provide sanitary protection until it is piped into the customer's system.

  • Well caps require an air vent. If the well is enclosed in a building or confined space, the air vent should always be extended to the outside atmosphere.

  • The vent pipe must be shielded and screened to prevent the entry of foreign material.

  • If drilling produces poor quality water, the water can be sealed off. One method is to install additional casing or liner inside the original casing and grout it into place.

  • If the water quality remains unsatisfactory, or if a construction defect cannot be remedied, the well must be abandoned and completely sealed to prevent cross-contamination between sites.
