What does 2.5m³ of water cost?

I'm in the US, but I like running numbers... that's 152559 ci I think, or
660 gallons. I get about 4 gpm out of our well, so that's 165 minutes of
run-time, or 2.75 hours.

The well pump uses a 750W electric motor, and electric is about 9c/kWh,
so that's 6.75c/hour to run the pump. 2.75 x 6.75 = 18.56c total cost.

In other words, just a shade under 12 pence.

If you want to factor in the cost of drilling/installing a new well, then
(assuming a 20 year lifespan, although we've got 26 years on our well and
35 on the pump) add 4p to the above.
