Water use

Water is a critical resource and we take responsibility for the water we use in our natural gas operations very seriously.

We take a responsible approach to the sourcing, use, transport and disposal of water. We recognize that the water requirements and challenges posed by our operations require tailored approaches to water management. We work to reduce the use of freshwater through the sourcing of alternatives wherever possible. Each of our resource plays has its own water strategy, which may include sourcing both surface water and groundwater.

We have also developed corporate guidance on water tracking and reporting as part of Ethos, our company-wide EH&S management system. This guidance helps us to:

• incorporate industry best practice
• set company standards on collecting, maintaining and reporting water data
• promote the efficient use and protection of surface and ground water
• promote the use of unutilized water such as saline, non-potable water from deep formations and recycled water
• encourage watershed planning when developing projects
