There are 2 kinds of sewerage charges – service charges and volume charges:
These are based on the number of major sewerage fixtures such as toilets or urinals. It is the owner's responsibility to let us know if the number of fixtures at the property changes or is different to what is shown on your bills.

Volume charges for sewerage apply if you discharge more than 200 kilolitres (kL) of wastewater during a financial year.
The charge is $3.453 per kL discharged.
How do you calculate the volume charge?
The volume charges are based on the percentage of total water used that is discharged to sewer – the discharge factor. Your discharge factor will either be the default of 95% or another amount which has been set based on an individual assessment of your business.
Based on your discharge factor, we calculate the amount of total water discharged to sewer, minus the 200kL discharge allowance, and charge $3.453 per kL discharged.
Example calculation 1
For a business that has used 3,000kL of water and has a discharge factor of 33%, your sewerage volume charges would be calculated as follows:
33% of 3,000kL = 990kL of water discharged to sewer
990kL – 200kL discharge allowance = 790kL
790kL x $3.453 = $2,727.87
Example calculation 2
For a business that has used 1,000kL of water and has a discharge factor of 10%, your sewerage volume charges would be calculated as follows:
10% of 1,000kL = 100kL of water discharged
No charge, as this is within the 200kL discharge allowance.
