33.3 Groundwater access entitlement for allocation extraction

Supporting Information

Two classes of groundwater access entitlements (urban and other lumped) are available in the Sydney region. The urban class includes entitlements for local water utilities. The other lumped class (aquifer licence category) may be issued for a wide range of purposes including irrigation, commercial, industry and environmental. It is not possible to provide a breakdown on the purpose of the right.

The following table was produced by mapping the rights of different categories for the Sydney region.

Attributes of the right

Groundwater access entitlement is specified on a water licence, expressed as a volume (in ML). The amount of water a licence holder is allocated as a result of an allocation announcement and the amount they can take in any year is based on their entitlement.

In any areas where no allocation announcement has occurred, the water available for the 2010–11 year was assumed to be 100% of entitlement.
