24.8 Adjustment and forfeiture of allocation/claim on regulated flows—urban water access entitlement/arrangement

                             

Supporting information   


Forfeiture of allocation for the line item is 521,320 ML.

This line item reflects unused portion of the allocation/claim associated with the water distribution system store for the urban water utilities. The volume for the line item is the difference between calculated volumetric allocation/claim stated in Line item 23.8 (1,022,865 ML) and regulated diversions stated in Line item 19.8.4 (501,545 ML).

 

Quantification approach   


Data source

Entitlement information was extracted from:

 

Data provider

  • The Bureau of Meteorology: calculated adjustment and forfeiture of allocation/claim.
  • The NSW Office of Water, Goulburn Mulwaree Council, Lithgow City Council, Shoalhaven City Council and Wingecarribee Shire Council: entitlement information.
  • See ‘Data provider’ in Line item 14.7.4 Metered diversions from reservoirs.

 

Method

Water management licenses issued to the urban holders by the NSW Office of Water applicable to 2009–10 did not make provisions for the carry over of any remaining allocation at the end of the year. Therefore, forfeiture of allocation on regulated flows for the entitlement category is the difference between the announced allocation/claim and measured diversions from the reservoirs for 2009–10. Calculation methods for the announced allocation and measured diversions are available in:

  • Line item 23.8 for the volumetric value for the announced allocation from regulated flows for the urban holder category
  • Line item 14.7.4 for metered diversions from reservoirs.

 

Uncertainty

Adjustment and forfeiture of allocation/claim was estimated. Uncertainty is ungraded.

 

Approximations, assumptions, caveats/limitations

See ‘Approximations, assumptions, caveats/limitations’ in Line item 23.8 for volumetric value for the announced allocation/claim, and in Line item 14.7.4 for metered diversions from reservoirs.
