ADELAIDE PLAINS WATER SUPPLY STUDY

In reply to Mr PEDERICK (Hammond) (1 July 2009).

The Hon. K.A. MAYWALD (Chaffey—Minister for the River Murray, Minister for Water Security): The Adelaide Plains Water Supply Study is a project to investigate the use of groundwater as an alternative supplementary water source for Adelaide. Preliminary findings from the study indicated there is potential for approximately 10 GL per annum.

The next stage of the project will comprise detailed design, construction, and operation of a pilot system to assess the feasibility of treating T1 and T2 aquifer water for possible blending into mains supply.

SA Water's investigations to date include groundwater quality measurements, well location survey, and preliminary concept design work has already been undertaken.
