I have a Mill in France that has a new Borehole, located circa 40
metres away, the Large size conduit (circa 5 inch) is already buried in
the ground, I am going to fit a Borehole pump 20 metres down the hole,
then run the wire through the conduit to the Mill.
But how do I get the wire to feed 40 metres down the conduit?, I have
read on the net that I could use curtain wire, but will this feed 40
metres without Kinking? I am reluctant to purchase a Quick cable set as
they come in 10 metre lengths and I would need to buy 4 of them for a
one off job.
Any suggestions would be appreciated.

Hire half an hour of a professional drain inspector's time? He could
just tie a bit of string to his camera and poke it through. If there's
any possibility of a blockage or discontinuity in the conduit, this
procedure has obvious advantages.

You might offer to hose down his reel before starting. :-)
