Calculate your stormwater offset contribution

Stormwater offset contributions are paid by developers to reduce the impacts of stormwater pollution from urban developments.

Developers pay a contribution to us for necessary stormwater management works if they don’t meet their stormwater objectives. Contributions are paid as development occurs.

Stormwater offset contributions apply primarily for areas outside of drainage schemes. However, some drainage schemes also include a stormwater offset rate.

Important note
The table below shows the rates per hectare for each municipality.
Use the calculator for the relevant council to calculate your contribution based on your development type and size.
