Contributions are paid as development occurs, and properties contribute on the basis of the development area and development type.
Self-assess your likely contributions
Locate your development:
- find your development site on our scheme maps
Calculate your contributions:
- if you're inside a scheme use the scheme contribution table
- if you're outside a scheme use the stormwater quality offsets rates table
If your development is on the border of a scheme or municipality, your contributions would be apportioned accordingly.
Enter the development area, the development type, and the percentage of best practice your development achieves for on-site water quality treatment. On-site water quality treatment can be used to obtain a water quality contribution reduction.
Development types are available in our Contributions policy.
Some schemes have no quoted water quality rate, as it's expected water quality works will be done on-site. Contact us if this isn't feasible.
Contributions in detail
Our Contributions policy contains more detailed information on contributions, covering topics such as:
how contribution rates are derived and applied
definitions of development types and their associated contribution ratios
when contribution exemptions may be applicable
