Sydney
6.1 Groundwater allocation remaining

This line item (0 ML) represents the volume of remaining groundwater allocation for other lumped class entitlement holders in the Sydney region.

Entitlements are specified on water access licences. They are expressed as unit shares in a defined licence category under the  Water Management Act 2000 (New South Wales).  The water volume allocated to a licence holder is derived from an allocation announcement and the licence holder's share component.

An aquifer licence category in New South Wales may be issued for a wide range of purposes including irrigation, commercial, industry and environmental. It has not been possible to provide a breakdown of each component for the purposes of this account.

While carryover of unused groundwater allocations is allowed, the carryover volume could not be quantified. Therefore, for the purposes of the National Water Account, the opening and closing balance (carryover volume) reported was 0 ML. 

Reconciliation of this line item is shown in the following table.

Under the Water Sharing Plan, carryover of any unused allocation at the end of the year is allowed for groundwater access licences. The maximum volume of carryover allowed is determined by the rules in the Water Sharing Plan and the volume of water extracted under the licence. As the volume of water extracted under these licences could not be quantified, the carryover volume could also not be quantified. Therefore, for the purposes of the National Water Account, the carryover volume (opening and closing balance in line item 6.1) was assumed to be zero.

As extractions and carryover were not quantified, the opening and closing balance for the groundwater allocation remaining were assumed to be zero.

Uncertainty was not quantified.
