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. ]


Thanks for that. I have just looked at the last bill (£189 for 3 months) and
they charge £1.15 for water and 1.21 for sewage per cubic metre. They arrive
at the sewage charge by calculating 95% of the incoming water volume. So if
I can pump 26 cubic metres for 18p that sound like its well worth buying a
pump.

Next job will be to open up the well and install a manhole cover. Then I
shall probably hire a pump for a weekend to see if the well can sustain the
water supply.

If you fit a meter to your outside tap, you should be able to show
that you return less than 95% to the sewer.
I returned 56% last year. I have a small veg garden and two garden
ponds. Unfortunately despite much arguing I had to pay for the meter
myself.
What other organization could insist that you have to supply your own
measuring device or accept their own gross overestimation.
This could only happen in rip off Britain.
