9.1.3.3 Groundwater entitlement—industrial and commercial holder

Supporting information

The volume reported in the water accounting statement (14 ML) represents carryover on groundwater allocations held for industrial and commercial purposes at the end of each financial year. It is presented with the other line items relevant to industrial and commercial groundwater licences in the table below.

Calculation	Line item	Volume (ML)
	Opening balance (1 July 2009) 9.1.3.3 Groundwater allocation remaining—industrial and commercial holder	11
add	27.1.3.3 Groundwater allocation announcement—industrial and commercial holder	812
minus	16.5.3.3 Groundwater allocation extraction—industrial and commercial	370
minus	28.1.3.3 Adjustment and forfeiture of groundwater allocation—industrial and commercial	439
	Closing balance (30 June 2010) 9.1.3.3 Groundwater allocation remaining—industrial and commercial	14

The breakdown of groundwater industrial and commercial allocation remaining for the prescribed areas within the Adelaide region is detailed in the table below.

Management area	2008–09	2009–10
Barossa Prescribed Water Resources Area	NA	–^a
McLaren Vale Prescribed Wells Area	11	14

– = Not available; NA = Not applicable; ^a = Carryover for 2009–10 had not been quantified in time to be included in the Adelaide region water accounting report.

Quantification approach

Data source

South Australian Department for Water: Water Information and Licensing Management Application (WILMA) database and Drillhole Enquiry System.

Data provider

South Australian Department for Water.

Method

The McLaren Vale Prescribed Wells Area (PWA) was the only area practising carryover of groundwater allocations (referred to as ‘allocation credits’ by Department for Water) at the end of 2008–09. Carryover for 2008–09 and 2009–10 was extracted from the WILMA licensing database. The purpose of water allocations and carryover was not identified in the McLaren Vale PWA. Instead, industrial and commercial licences were identified from the original purpose assigned to the bore when constructed. This information is recorded within the Drillhole Enquiry System database.

The Barossa Prescribed Water Resources Area (PWRA) began practising carryover of groundwater allocations at the end of 2009–10. Carryover had not been calculated for Barossa at the time the Adelaide region water accounting report was compiled and hence could not be included.

Uncertainty

Ungraded.

Assumptions, approximations and caveats/limitations

The current purpose of the groundwater licence is the same as when the bore was constructed and recorded in the Drillhole Enquiry System.
All bores with an industrial purpose were captured in the Drillhole Enquiry System.
Bores with an industrial purpose were used entirely for industrial use.
All allocations without an industrial purpose were assumed to be used for irrigation.
