33.2 Groundwater access entitlement for direct extraction
This line item consists of the metered licensed groundwater extractions in the Canberra region. Data were not available for the New South Wales (NSW) portion of the Canberra region.
In the ACT, individual licensees submit meter readings for each month to the ACT Environment Protection Authority (EPA) once per year. Where a licensee has not provided meter data, the EPA may assume use is 100% of entitlement or they may estimate the use.
Assumptions, Limitations, Caveats and Approximations
Derived from measured data. Meters are required to be accurate to the kilolitre (kL) +/–5%. Over 60% of meters are inspected each year to validate the readings supplied by licensees.
Estimated uncertainty is +/–5%.
This line item corresponds to line items 16.4.2 Groundwater extraction–other lumped basic rights reported in the 2010 Account.
