we use alot. all the people who say we use brackish water so that we can be allowed to use more of it, due to its un-consumabilty is bull. we use just normal water, apparently we are only allowed to use so much daily, but it would be interesting to know how much we use. All the SAGD plants like mine in comparison to a normal drilling derrick must use a ridiculous amount of water, as the actual way the plant extracts the oil is by heatin water to 296 degree celsius steam, shooting it into the ground at the speed of sound and using that as well as a lifting gas to withdraw the bitumen from several hundred meters below the ground
