12 Begin to realize the scarcity of the resource Bags of mostly water

13 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

14 Stats for private consumption in Canada On average 200 to 400 liter per person per day

15 How can we save Water efficient toilets Efficient showers Efficient faucets Washing Machines Fix leaks Become aware- meter the Water And finally GRAYWATER

16 Gray-Water What is it How does it work Why should I bother Items to look out for

17 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

18 How does it work? Residential Systems discharge the bathwater into an approved system- then use the graywater to flush the toilet


20 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

21 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

22 The WORLD is acting For Example: United States of America Australia European Union

23 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
