Port Bonython Fuels

at Port Bonython to provide water for the expansion of the Olympic Dam copper and uranium mine. The plant was approved by both State and Federal Governments in October, 2011. The plant had an approved capacity of up to 280 megalitres of produced water per day, or 137 gigalitres per year. At full capacity, this would result in 370 megalitres of waste brine with elevated salinity returned to the sea off Point Lowly.
During the preparation of the Olympic Dam Expansion Draft Environmental Impact Statement, scientists discovered that the region's population of Giant Australian Cuttlefish was genetically distinct and that it was vulnerable to increased salinity and changes in pH, particularly during embryo development.
Numerous people expressed concern about the potential impact of the plant on Spencer Gulf's salinity including prawn fishermen,
tuna growers, scientists
and environmentalists.
A small scale pilot desalination plant was established at Port Bonython and operated from 2007 to 2010. The pilot plant was established and operated by
Veolia Water Solutions and Technology and a monitoring station was operated by Water Data Services.
The proposal to construct a desalination plant was ultimately abandoned after the company decided to expand the mine using existing methods, rather than reconfiguring the mine to an open cut. If constructed, the plant would have been the second largest in Australia after the
