16.4.1 Groundwater extraction—stock and domestic basic right

                             

Supporting information   


The volume reported for this line item is an estimate of the total usage of groundwater from bores in the NSW portion of the Canberra region.

 

Quantification approach   


435 ML of stock and domestic water right.

 

Data source

New South Wales (NSW) Office of Water: Navigator Water Tools.

 

Data Provider

NSW Office of Water.

 

Method

Navigator Water Tools was used to locate 870 bores within the region. The usage of each bore was assumed to be 0.5 ML per bore for basic rights.

 

Uncertainty

Estimated uncertainty is +/–30% to +/–50% based on established practice and professional judgement by the NSW Office of Water.

 

Assumptions, approximations and caveats/limitations

  • Data to determine basic rights extractions in the reporting area is extremely limited. While an average 0.5 ML per bore is considered a reasonable assumption for the amount of water that could be attributed to this use, the accuracy around this assumption is largely unknown.
