Your bill & charges
We use the rateable value of your property to calculate the wastewater and drainage charges.
The rateable value is based on the annual rental value of your property, which is what you might receive if you leased out your property, or by a percentage of the vacant land value. Landgate Property Valuation Services provide this figure.
The calculation of a rateable value for a residential property is based on a number of factors, such as:
- proximity to services (schools, public transport, shops etc)
- age and functionality
- additional facilities
- provided accommodation
- size and area
- age of property.
For residential vacant land and other specialised properties, the rateable value is based on 3% of the property's capital value, or the amount the land and any buildings might reasonably sell for.
Properties in the metropolitan area are revalued every 3 years, and regional areas are revalued on a recurring basis dependent on local governments.
There is also a process each year, which assesses properties that have had additions or improvements done.
Aside from metropolitan and regional variations there are certain groups of customer who have different charges or discounts that apply. You can view the pricing variations list for more details.
