fitting 100 is positioned on well casing 12 so that fitting 102 covers the exact location in which opening 20 is to be effected and pipe fitting 140 faces the top of the well with electrical conduit 32 connected to pipe fitting 140 alternatively casing fitting 100 can be placed on well casing 12 before well casing 12 is disposed in the well shaft conveniently electrical conduit 32 can be used to move casing fitting 100 vertically and horizontally on well casing 12 to its precise position grouting cement is then poured into upper portion 152 of the hole and allowed to harden forming grouting wall r as shown in fig4 b once grouting wall r has been formed an access shaft 154 is excavated next to grouting wall r parallel to electrical conduit 32 down to the depth of casing fitting 100 exposing outward facing first cover 110 see fig3 if a thin shell of cement is present it can easily be chipped away with hand tools such as a chisel cover 110 is then removed for example by loosening the adhesive with a knife and prying cover 110 away with a screwdriver a drill 156 having a circular bit 158 can then be inserted into access shaft 154 with circular bit 158 placed inside fitting 102 an opening is then drilled through cover 112 and well casing 12 using center mark 146 as a guide for placement of circular drill bit 158 a torch can be used in place of drill 156 to effect the opening through cover 112 and well casing.
