10.8 Managed aquifer recharge - private user
The volumetric value for the line item for the 2010–11 year was 4,158 ML. The line item comprises of managed aquifer recharge volumes from Angas Bremer (Quaternary Sediments and Murray Group Limestone) groundwater sustainable diversion limit (SDL) area in South Australia. Information from other groundwater SDL areas was not available for the line item.
Recharge was initially carried out in Angas Bremer to improve the quality of the groundwater and to store surface water flows during the non-irrigation season. Currently, the River Murray pipeline capacity is not capable of delivering all water demands during the peak of irrigation season, meaning licensees will need to take water off-peak and store it in the aquifer for later use.
Recharge volumes were metered.
