Calculate average daily water usage

Work out how much water you use

Find out the average volume of water a property or piece of equipment uses daily. Enter a start and end date, or the number of days you're interested in, as far back as 1 July 2009. If you need to know the cost of the water a property has used for a specified time, calculate your water usage charge.

This tool doesn't calculate fixed service charges or the total bill for your property. For your fixed charges, use the fixed charges calculator.
