Augmentation

Augmentation

Augmentation occurs when our network capacity needs to be increased to support current and future growth needs.

Augmentation charges are in addition to other fees and charges and are payable in addition to costs normally associated with land development. They recoup costs in relation to the incremental impact from development on our infrastructure upstream (for water) and downstream (for wastewater), including impacts on significant trunk mains and water/wastewater treatment.

The Augmentation charges for 2024-25 align with the National Housing Accord and South Australia’s housing roadmap.

From 1 July 2024, augmentation charges are applicable to all new incremental allotments within the Greater Adelaide Region.
