Metered Savings
How Can I Estimate What I Will Save?
Obviously the amount of water usage will vary from property to property. You will need to obtain an idea of the likely annual consumption of water in your property in order to determine the possible savings you may make.
The table shows the estimated consumption of water for various functions in the home.
Basic Use - cooking - drinking,
personal hygiene (excluding bathing)

1000 LITRES = 1 CUBIC METRE = 220 GALLONS
As a rough guide, you can base your calculations on a person using 60 cubic metres per annum for normal domestic use.
Please remember that the figures quoted are for guidance only, if in doubt it is better to err on the side of caution and increase your figures for consumption.
Using these assumptions the following table gives the possible saving on a household's water bill over the period of one year where the water rate is currently based on the sample rateable values listed.

If you save on your water bills you are also likely to save on your sewerage bills. You will need to work out your sewerage saving and add that to your water savings.
