The chart below shows the average amount of water used per household per day in Sydney.

\n

These amounts depend upon the number of people in the household, the size of the property in square metres, and the billing quarter (three month period).

A 5-person household living on a large property uses an average of 666 L of water daily. This is an increase of 168 L from the 3-person household.
666 L + 168 L = 834 L. We are looking for an answer smaller than this.
