3. Set up

The set up of the casing is a crucial step within the development of a nicely. You will need to be sure that the casing is correctly put in to forestall the nicely from collapsing and to guard the groundwater from contamination.

  • Side 1: Reducing the Casing

    The casing is usually lowered into the wellbore in sections. Every part is usually 10 to twenty toes lengthy. The sections are lowered into the wellbore utilizing a crane or different lifting machine.

  • Side 2: Welding or Screwing the Casing

    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 also be an choice.

  • Side 3: Grouting the Casing

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

  • Side 4: Disinfecting the Casing

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

The set up of the casing is a fancy and essential course of. You will need to be sure that the casing is correctly put in to forestall the nicely from collapsing and to guard the groundwater from contamination. By following the steps outlined above, you possibly can be sure that your nicely is correctly cased.
