System role
Water is used in ore transport and bitumen separation, then recovered from process and tailings streams.
How it is managed
AER reports substantial recycling in mining while also identifying mining as the oil-and-gas extraction category with the highest nonsaline-water use.
Environmental context
Water recovery can reduce new withdrawals and tailings inventory growth.
What to keep in mind
Good reuse performance does not remove the large accumulated tailings-water challenge.
