Water –Our scarce Resource
CPAA Conference
April 4-6 2011
Peter Lehner
Director CPAA
Look from Space
My Goal
The begin a conversation while we still have a choice.
Get YOU thinking about WATER
How much do we really have?
Shocking?
Begin to realize the scarcity of the resource
“Bags of mostly water”
Value of Water
Water contributed between 7 to 23 Billions worth of Value to the economy in Canada in 2008
Our cost for that was “ZERO”
Stats for private consumption in Canada
On average 200 to 400 liter per person per day
How can we save
Water efficient toilets Efficient showers Efficient faucets Washing Machines Fix leaks Become aware- meter the Water And finally “GRAYWATER”
Gray-Water
What is it How does it work Why should I bother Items to look out for
Gray water is ?
“Gray water” is wastewater from your washing machine, bathroom sink, bathtub, and shower. Kitchen sink and dishwasher water is not to be considered “Grey water”
Water from your toilet is “Blackwater”
How does it work?
Residential Systems discharge the bathwater into an approved system- then use the graywater to flush the toilet
Why should “YOU” bother?
It is the LARGEST potential source of water savings for your residence
Make a powerful contribution towards using this precious resource and not wasting it
Items to look out for!
Your system has to have a way to discharge into a sewer system in case of plugging or other problems
It has to be separated from Water for Human Consumption
It has to meet local building and/ or plumbing codes
The WORLD is acting
For Example:
United States of America
Australia
European Union
USA
More then 20 States recognize the NEED and have passed “Graywater Laws” or they are in the process of doing so
They could be used as templates for local legislation
Australia now
Though initially driven by the constraints of drought, some of the graywater schemes will help meet water supply needs well into the future.
European Union
They are well on their way to create a Common Gray-Water Policy
Where is Canada
Where is Alberta How can you get involved
Municipal Level Provincial Level Federal Jurisdiction?
Domestic Successes
Use and adopt proven strategies
Control Cost
Make a real impact on consumption
Maintain our quality of life
Living Machines
