Back to Bikeke this afternoon to check water depth and start
brick work to complete the well.
Water depth is a strong 2.2 meters … exceeding our
expectations & minimum needed to continue on with well completion.
Bricks are used in two places to compete the well.
(I) Four to six courses are used on top of the culverts (at
bottom of the well) to one; transition from the fixed diameter of the concrete
culverts to the slightly irregular diameter of the hand dug well hole, two; to
prevent any movement of the culvert within the slightly larger diameter well
hole, and three; to prevent any soil at the top of the culvert section from
spalling off and falling into the well bottom.
(II) Another three to four courses are placed at the top of
the well to provide support for the well head concrete work and reduce the
diameter of the well hole to match exactly with surface equipment. This top set
of bricks is supported on a ledge which is notched into the strong clay of the
existing well hole wall.
Next step will be the concrete work at the surface; for the
well head base and work area … this will commence on Monday with well completion
still set for the 15th …
Excited Children but their patience is wearing thin ... not really ... they are just so ready to see the water ... (as we all are!) ... they are learning a lot as they watch the crew work ...
