So my original plan to just drop the submersible pump down there as required
may not work as I doubt it will lift the water that far. I now wonder if
investing in a better pump would be worthwhile as the electricity used to
lift the water may cost more than I pay the water authority.
Anyone have any experience in the cost of running a pump at that depth?
Why not do the calculations? I assume that you know the cost of
water per cubic metre, and electricity per kilowatt-hour? Clearly
pumps won't be more than 100% efficient, but they can get close.
[ In case you are mathematically challenged, the answer is that you
can lift about 26 cubic metres of water for a kilowatt hour. ]

According to my water meter readings that would provide my (single)
household for about one year.
