Lift the flap on the top of your meter to reveal the current reading. Depending upon the type of meter, it will look something like either of the images below (if you have an older meter the colours on the dials might be different).
As illustrated above, the numbers with the white background represent kilolitres. The numbers on the red background show your water usage in litres. The litre numbers are for test purposes, including testing for water leaks and meter accuracies.
A kilolitre is equal to one thousand litres - an average household will use approximately 200 kilolitres per year. TasWater calculates your water usage bill in kilolitres only, so for the example above you would be billed for 13 kilolitres.
