    As soon as the casing is lowered into the wellbore, the sections are welded or screwed collectively. Welding is the commonest technique of becoming a member of the casing sections. Nevertheless, screwing the sections collectively can be an choice.

  • Side 3: Grouting the Casing

    As soon as the casing is put in, it’s grouted. Grouting is a strategy of filling the house between the casing and the wellbore with a cement-based materials. Grouting helps to forestall water from leaking into the effectively from the encompassing soil or rock.

  • Side 4: Disinfecting the Casing

    As soon as the casing is grouted, it’s disinfected. Disinfection is necessary to forestall micro organism from coming into the effectively water. Chlorine is the commonest disinfectant used for wells.

The set up of the casing is a posh and necessary course of. You will need to be certain that the casing is correctly put in to forestall the effectively from collapsing and to guard the groundwater from contamination. By following the steps outlined above, you may be certain that your effectively is correctly cased.
