The calculator provides a best estimate of usage based on the responses you provide. The calculator estimates typical water use for households with similar characteristics to those provided by you. Your actual usages displayed on your account may be different to the results from this calculator. This may be due to incorrect estimated responses, the expected variation in water use even for correct responses, unknown leaks or water use not covered by the calculator such as dialysis. As the level of garden watering increases, the accuracy of the calculator may reduce due to the complexity of estimating this component of use. Yarra Valley Water takes no responsibility for variations between the estimated total usage provided in the calculator and your actual account.
