Global Comparison - Annual Natural Water Supply Per Person(1995)
Water Resources in Canada and Alberta
Canadians do not show up well on OECD Environmental Water Indicators
Trend
Since 1980, overall water use in Canada has increased by 25.7%. This is five times higher than the overall OECD increase of 4.5%.
In contrast, nine OECD nations were able to decrease their overall water use since 1980 (Sweden, the Netherlands, the United States, the United Kingdom, the Czech Republic, Luxembourg, Poland, Finland and Denmark).
Perception that we squander water exacerbates issue of water use in resource extraction
“Wild unregulated pillaging of the environment at the expense of the First Nations … that is what the Europeans think of us.”
Minister Rob Renner (Chamber of Commerce May 25, 2010)
“More and more our investment partners are trying to steer us away from investments in oil sands and coal technologies.”
Scott MacDonald, Partner Emerald Ventures (June 12, 2010)
Protestors demonstrate outside the U.K. headquarters of BP in London on Sept. 1, 2009. Protestors earlier targeted the head office of a leading bank, demonstrating against the bank's investments in fossil-fuel projects, especially funding for the coal industry and tar-sands extraction in Canada.

Oil and Gas Industry most likely to adapt
Challenges:

The Oil Sands Leadership Initiative

Alberta Environment, Alberta Energy and SRD participate as
observers
Five founding companies:
www.OSLI.ca
Major investments in Technology in Oil Sands
Advanced boiler technology that could take untreated (or lesser-treated) water directly
Ceramic membranes for more efficient SAGD de-oiling & filtering
Tailings recovery technology allows for faster reclamation of tailings areas and higher water recycle rates
Challenge: Currently operators in the oil sands
region are working independently to solve their individual water sourcing and disposal needs.
Project Objective: Lower the regional environmental
impact (water, land, wastes, GHGs)
Project Description Examine the potential to reduce
environmental impact through regional collaboration.
Potential Benefits Lower regional Environmental Net
Effect Reduce tailings liability Establish reliable SAGD water sources Accelerate tailings reclamation
