Adelaide
11.15 Increase of inter-region claim on water by urban water system

Supporting Information

During the 2010–11 year the South Australian Minister for Sustainability, Environment and Conservation announced that the volume of water available for abstraction under the Class 6 water access entitlement to River Murray water was 150,000 ML.

More information on the entitlement can be found at line item 3.4 Urban inter-region claim on water.

Method

During the 2010–11 year the South Australian Minister for Sustainability, Environment and Conservation made several announcements notifying the volume of water available for allocation from the River Murray consumptive pool. These announcements were published in the South Australian Government Gazette and reached a maximum water allocation rate of 115.4% of 1 kL/unit share for the Class 6 water access entitlement. Based on this allocation rate and the number of Class 6 shares held, the volume of water reported was 150,000 ML.

Assumptions, Limitations, Caveats and Approximations

The Class 6 water access entitlement is represented as a claim held on behalf of the Adelaide region. However, a proportion of the water abstracted under this claim services users outside the boundary of the Adelaide region.

Uncertainty Information

The uncertainty estimate was not quantified.

Comparative year

This line item corresponds to line item 23.4 Other lumped non-physical surface water asset increases reported in the 2010 Account. In the 2010 Account the Class 6 water access entitlement for River Murray water (the entitlement) was reported as an inter-region claim held by the Adelaide region's surface water store. However, in the 2011 Account the entitlement was reported as a claim held on behalf of the Adelaide region's urban water system. This change was made because River Murray water abstracted under the entitlement is transferred directly into the Adelaide urban water system (although there is some subsequent discharge to surface water). Thus, representing the entitlement as a claim held by the urban water system provides clearer information for the user. Despite reclassification of the River Murray entitlement, the volume reported did not change. The restated volume for the comparative year was 150,000 ML.
