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.
