9.2 Broken Hill managed aquifer recharge project This project aims to reduce evaporation and improve efficiency at Menindee Lakes in order to secure Broken Hill’s water supply, protect local environment and heritage, and return 200 GL of water to the environment. It investigates whether surface water from the Menindee lakes could be stored underground and later extracted to provide supply to Broken Hill during times of drought. Geoscience Australia undertook the hydrogeological investigations including airborne electromagnetic survey, drilling of more than 60 boreholes to collect geological information, construction of monitoring bores, down-hole geophysics and water quality sampling. | NSW Office of Water, January 2013 68 Western Murray Porous Rock and Lower Darling Alluvium Groundwater Sources | NSW Office of Water, January 2013 69 Investigations so far indicate that the aquifers within 20km of the existing Menindee-Broken Hill pipeline have some 1,200 GL of managed aquifer recharge storage potential. There are seven potential aquifer targets, at depths that vary from 10m to 150m (DSEWPG, September 2010).
