RIWI Act, Groundwater Areas
The Rights in Water and Irrigation Act 1914 (RIWI Act) provides the Governor of Western Australia the power to proclaim or prescribe a groundwater area through regulation. Proclaiming or prescribing an area allows comprehensive management of water uses in that area.
For the purposes of groundwater resource management, the state of Western Australia is divided into groundwater areas. The extraction and licensing of groundwater resources are managed within groundwater areas.
