How much water does an ‘average’ person/household use?

Because water usage varies enormously, it is difficult to give a precise answer on average water use. The table below provides an estimation of what we believe is a rough figure. You can monitor your own usage by reading your meter regularly or comparing the consumption recorded on your bills. This could also help you to identify leaks or other problems (for which you may be responsible).

The table below gives a guide to average water use based on the number of occupants. It is based on figures provided by Waterwise and average customer entries into our water meter calculator.  For information based more closely on your own usage, please visit our water meter calculator.
