Water use

Remarks:

Non-saline water is water having a total dissolved solids content of 4000 mg/L or less. Sometimes referred to as fresh water, but it may require treatment before it can be used for domestic or agricultural purposes. It is a source of make-up water, that is added to an energy process to replenish water that is lost during that process and to supplement recycled water.

Alternative water is water other than surface water and non-saline groundwater, including saline groundwater, produced oilfield water, hydraulic fracturing flowback water, and wastewaters. It is a source of make-up water, that is added to an energy process to replenish water that is lost during that process and to supplement recycled water.

Recycled water is water that was previously used in or produced from an energy activity and is then reused by operators in that same process.

Data on water use of oil and gas extraction is only available for Alberta but neither for the national (Canada) level nor other provinces, that could be used to manually calculate the data for the national level.
