Sara, I have just found my annual statement. I have used 24 cubic metres in 10 months! And the figures are actual readings, not estimated.
We get showers rather than baths, and we sometimes flush the loo with water from the garden butt. My washing machine is run about 4 times a week, and my dishwasher 3 or 4 times a week.
The figures Ethel's quoted are very high compared to my usage - the Water Board has given us an estimated figure of usage which is 30 cubic metres per year. And that's not per person, that's the total household usage.
The Water Board has given us a projected total for a year's water - �144.00.
If we were paying based on rateable value, we would pay �580 per year.
