Supporting information   


The table below shows the breakdown of groundwater extracted for the SEQ Water Grid supply in each water resource plan (WRP) area within the South East Queensland (SEQ) region.

Volume of groundwater taken for SEQ Water Grid supply
WRP area Groundwater treatment plant Volume (ML)
Moreton Runcorn Aquifer 245
Sunnybank Aquifer 199
Linville 12
Logan Basin   0
Gold Coast   0
Total SEQ region   456

WRP = water resource plan

 

Quantification approach   


Data source

Queensland Water Commission (QWC), WaterHub database.

 

Data provider

QWC.

 

Method

The volume of groundwater taken for water supply in the 2009–10 reporting period was calculated by summing the water produced at all groundwater treatment plants (GTPs) that feed from a groundwater source within the SEQ region.

 

Uncertainty

Derived from measured data. Estimated in the range +/– 20%.

 

Approximations, assumptions, caveats and limitations

There may have been some loss of water during the treatment process; therefore, the volume of water extracted from the source will be an underestimate.

GTPs in Bribie Island and Stradbroke Island were not considered as they are located outside the National Water Account 2010 definition of the SEQ region. The volume of water produced from these plants was quantified as an import to the SEQ region.
