Water supply for the town of Alice Springs is obtained from the Roe Creek Borefield, 15 km to the south-southwest. This borefield currently consists of 20 production bores which pump water from four discrete aquifers in three formations in the Amadeus Basin: Mereenie Sandstone, Pacoota Sandstone (2), and Shannon Formation. Annual extraction is of the order of 10 x 106 m3, of which more than 80 per cent comes from the Mereenie Sandstone. Peak daily extraction rates are 55 000 m3. Regional investigations show that the Mereenie Sandstone will continue to be the major source of Alice Springs water supply. Models have been developed to determine the economically sustainable yield from the Roe Creek Borefield. These models indicate that borefield abstraction is primarily from local aquifer storage, and, as such, drawdown is linearly related to total withdrawal from the aquifers.
