I'm just wondering how many cubic metres of water people in this group
use per week or per quarter or whatever. Mine seems very low.

1.54 cubic metres/week for the 2 of us.

I have just checked my annual figures - I record E, G and W reading
weekly in a spreadsheet. We (two of us) used 63.227 last year, this
year at week 47 of 52, we are at 61.776 so probably a little more than
last week.
