28.1.3.5 Adjustment and forfeiture of groundwater allocation—individual holder for stock and domestic

                             

Supporting information   


The volume reported in the water accounting statement (159 ML) represents the forfeiture on stock and domestic groundwater licences issued for the Northern Adelaide Plains Prescribed Wells Area (PWA). Stock and domestic groundwater allocations only occur in the Northern Adelaide Plains PWA when there is a request to extract water for stock and domestic water purposes on a bore licenced for another purpose, typically irrigation. Stock and domestic extraction in the Adelaide region is more usually associated with a basic right.

South Australian Department for Water.

 

Method

Stock and domestic groundwater licences only occur in the Northern Adelaide Plains Prescribed Wells Area (PWA). Allocation and metered extraction data for 2009–10 were extracted from the WILMA licensing database for Northern Adelaide Plains PWA. Carryover is not permitted in this prescribed area. The allocation and metered extraction data were used to calculate forfeiture (referred to as the ‘unused authorisation to take’ by Department for Water), as shown in the table below.

Assumptions, approximations and caveats/limitations

Strictly speaking, the allocation remaining (referred to as ‘unused authorisations to take’ by Department for Water) is forfeited at the end of the water year and results in a credit towards allocations for the following water year.
