• Water holds a positive• charge and a negative• Charge (H2O)
• Hence, water forms a film
• The film is adhesive
• Water can defy gravity – capillary rise

Where should we look to save water?
• Bathing 80 – 31%• Bathroom Sink 8 – 3%• Cook & Drink 12 – 5%• Dishwashing 15 – 6%• Laundry 35 - 14%• Toilets 100 – 39%• Utility sink 5 – 2%
• Yearly total 93,075 Gal.
• Conventional irrigation on a mere 3000 square foot lot - 203,000 gallons per season
• Force people to use efficiency toilets and then monitor them to flush only once – save 18,000 gal./yr.
• Install efficient EPIC™ irrigation and save – 110,000 gallons /yr.
• Reuse shower water and add 29,000 gal/yr
