4. Rainwater Harvesting Key Drivers
• 36 states are anticipating local,
regional or statewide water
shortages by 2013, even under
non-drought conditions.
• Some Facts:
– Water covers over 71% of the earth’s
surface
– Therefore many people think water is
in limitless supply
– However 97% of the water is salt
water
– 2% of this water is in the form of
glaciers
– Less than 0.5% is available for
City of Tucson, AZ requires 50%
human consumption of irrigation be fulfilled by
rainwater harvesting on all new
commercial buildings.
Water Shortages Drive Legislation & Behavior Change

5. Increased Demand
• As the U.S. Population continues to grow our available water supply
does not.
• The wars of the 21st century will be fought over water.
- Ismail Serageldin, World Bank Vice President for Environmental Affairs
We Are Entering An Era Of Water Scarcity

12. Water Harvesting – Major Components
Complete Turnkey Solutions For Water Harvesting & Reuse

13. UW Milwaukee Residence Hall
Objectives
To reduce municipal water usage for
irrigation at a University of Wisconsin
Milwaukee Residence Hall by as close
to 100% as possible.
Requirements
• Water usage is 100% irrigation.
• Collection location: Rooftop
• Water Storage : 20,000 gallons
• Full tank provides 2 weeks of irrigation
Results
• System collects 11,000 gal on a 1” rain event.
• 1” of rain = 4 irrigation cycles (1 week of irrigation)
• The tank is filled completely on a 1.7” rain event.
• The SkyHarvester system reduces potable water
consumption for irrigation by at least 94%

14. Dale City Fire Department
Objectives
To completely eliminate municipal water usage
for irrigation and attain LEED certification at the
Dale City, Virginia Volunteer Fire Department’s
New Station 10 facility.
Requirements
• Water usage is 100% irrigation.
• Max Irrigation Cycle; 3600 Gallons
• Water Storage : 11,000 gallons
• # of irrigation cycles possible: 61
Results
• Cut Municipal Irrigation Water Use by 100%
• Unique Tank Controls Automatically turn
The system on and off based on rainfall
• Earned maximum LEED points

15. UNUM Insurance Case Study
Objectives
To reduce municipal water usage at UNUM’s new
Corporate Headquarters site in Chattanooga, TN.
Requirements
• Water usage is 100% irrigation.
• 7,950-9,750 Gallons per week needed
• Water Storage : 20,000 gallons
• Parking Lot Runoff - Oil / Water Separation
& In Tank Filtration For Grit Separation
Results
• System collects 20,000 Gallons In a ½” event
• 20,000 Gallons = 2.5 weeks of irrigation
• Reduced UNUM’s irrigation water
consumption by nearly 100%
Chattanooga’s Water Costs Are The Highest In the State

16. Successes & Challenges
Yet not Without Challenges
• Cost of water (still cheap)
• Unrealistic codes and water quality
standards for non potable water
• Non-potable / potable water system
interconnections (plumbing back up
water directly to the non potable side)
• Rainfall does not happen in large
amounts everywhere
• Legislation that says the water that falls
on your property does not belong to you
• Industry Fragmentation –”Industry
mavericks”….has the potential to give
rainwater harvesting a bad name when
done incorrectly
Category Is Still Seen As The Wild West!

17. Water Awareness
• The news is not all bad:
– Conservation efforts to date have stabilized water consumption despite
population increases.
– New conservation technologies are becoming mainstream.
• Low flow toilets and fixtures
• Water harvesting and reuse systems
• “Smart” and Efficient Irrigation systems – residential, commercial and
agricultural
– Water is starting to get the attention it deserves and regulations are
changing and being established.
Despite Challenges, Growth Is Driven By Prevailing Market Trends
