QGC has studied a number of ways to safely manage brine for the long-term. On balance, when all the safety, environmental, community and business factors are considered, crystallising brine into solid salt form and encapsulating it for long-term storage in purpose built cells (design life 150+ years) is the most feasible and optimum solution.
QGC's approach to water management is to maximise the use of this valuable resource. The QGC water treatment plants recover 97% of water for beneficial use. The residual 3% (brine) is currently safely stored in purpose built, dedicated ponds.
