The Water Footprint
■ Indicator Of Freshwater Use Throughout The Supply Chain
Water Consumption
Water Production
■ Volumetric Measure Of Consumption & Pollution Within A Defined System Water Reuse
Wastewater
Opportunities To Alter The Water Footprint ■ Water Reuse – Identify The Most Significant, Feasible Opportunity
Faucets 23% Baths 2%
Toilets 19%
Clothes Washers 21%
Other Domestic 3% Leaks Dish Washers 10% 2%
Showers 20%
■ Common Applications: – Irrigation – Heating & Cooling – Toilet Flushing
■ Fay School Applications – Irrigation Excluded Due To Drinking Water Supply Proximity – Toilet Flushing
Fay School Project Drivers
■ Cost Savings – Water Use Reduction
■ Altruistic Mission – Teaching Sustainability – Environmental Awareness – Stewardship
