Alberta
A few facts:
• 10% of Canada’s population
• 7% of Canada’s Land Area
• 2% of Canada’s Water
• 35% of Canada’s Agricultural Export
• > 80 % of Canada’s Fossil Fuel Production
• ~ 18% of Canada’s GDP

Water Treatment
• De-oiling (hydraulic fracturing flow back, EOR
fluids, thermal recovery, etc.)
• Silica removal
• DOC removal
• High temperature RO membrane
• Evaporative technology
• Zero liquid discharge
• In-situ steam generation

Water Reuse in Edmonton
• Reclaimed wastewater for
process applications to
Suncor’s 135,000 bbl/day
Edmonton refinery (cooling
water and hydrogen
production)
• Capacity of 15 ML per day
• Approx. 50%* of total water
withdrawn for use in
Suncor’s Edmonton Refinery
was from Gold Bar
• 5.5 km pipeline from the
Gold Bar WWTP to the
Suncor Refinery
*Based on 2010 figures
