Your business bills are generally made up of 2 types of charges:

  • Service charge
  • Water use charge

We take a meter reading every 2 months and send you a bill for your water use and service charges. You can find charges that apply to you on the back of your bill.

Billing periods

There are 6 billing periods for this financial year, between July 2019 and June 2020.

Service and water use charges explained

We calculate the service charge component based on the number of days in the billing period.

For non-residential properties in both metro and regional areas, water charges are based on the size of the meter servicing the property.

There is a minimum non-residential water service charge of $272.05 for unmetered and unconnected properties. 

Below you will find the breakdown of how our service charges are divided and more information on the available services.

There are 2 kinds of sewerage charges – service charges and volume charges:

Service 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.

Service charges based on the number of major sewerage fixtures
Fixtures Cost
1st fixture $1,021.18
2nd fixture $437.12
3rd fixture $583.77
4th + fixtures + subsequent $634.81

Volume charges

Volume charges for sewerage apply if you discharge more than 200 kilolitres (kL) of wastewater during a financial year.

The charge is $3.752 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 $3.752 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 $3.660 = $2,891.40
790kLx $3.752 = $2982.41

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.

Drainage charges are based on your property’s Gross Rental Value (GRV), or rateable value which is supplied by the Valuer General. The charge is calculated by multiplying a rate (cents in the dollar) by the rateable value.

Drainage service charge is $13.95 per parking bay/ storage unit.

Drainage service charge is $37.43 per metro strata-titled caravan bay.

The drainage tariff is 0.324 cents for each dollar of the rateable value.

You can now prepay your service charges for the financial year in your My Water account via the ‘My bills and payments’ tab.

The service charges for your property will be issued on the first bill of the new financial year along with the water use charges (for metered properties). From then on the water use charges will continue to be issued every 2 months.

If the service charge prepayment is selected for the full financial year, this will carry over to the next financial year for service charges as a default.

Please note that there is no discount for prepaying your service charges annually. We’re offering this as an alternative so that customers can manage their bills in a way that’s convenient to them.

Water use charges are calculated from the date of your last meter reading to the current meter reading.

Metropolitan

Metro non-residential customers are charged a flat fee per kilolitre.
