The amount of water you are charged for using is calculated from water meter readings approximately once every 90 days. The amount of water recorded is divided by the number of days in the reading period to work out, on average, how much water is used every day.
The first 440 litres per day are charged at the lowest step, water used between 440 and 880 litres per day is charged at the middle step and any water used over 880 litres per day is charged at the highest step.
For example, if you used 91 kL of water in the June quarter (91 days), this equates to an average daily use of 1000 L/day. In addition to the standard quarterly service fee, the water usage fee applied for the June quarter would reflect (an average of) 440 L / day charged at the lowest step, 440 L / day charged at the middle step and the remaining 120 L / day charged at the highest step.
