3. The Problem $5.3 Billion damage caused by flooding each year in USA $5.3 Billion damage caused by flooding each year in USA An estimated 75% of all flood damage is caused by water less than 3 deep An estimated 75% of all flood damage is caused by water less than 3 deep Single most used protection from this damage is temporary sandbag dikes Single most used protection from this damage is temporary sandbag dikes $158 Million spent on sandbags to protect New Orleans from Katrina $158 Million spent on sandbags to protect New Orleans from Katrina

4. Typical Solution to the flooding issue Currently………… Currently………… –300 Sandbag wall –56-5 ton truckloads of sand –700 Manhours –7000 bags –Shovels, tools, logistics –Redeployment, clean- up and landfill disposal Total Cost $62,550 Sandbags Set-Up Manhours

5. Sandbag barriers can be effective. However the amount of manpower and logistics required to build sandbag barriers is massive, and therefore not typically available in a time of imminent disaster.

16. ¼ Turn Fill / Vent Cap

17. Fill Nearing Completion (10-15 minutes)

18. Completion Second Unit Fill

19. What if a unit gets punctured?

20. Cuts and punctures will not run or rip. Even with a relatively large puncture the leakage rate is low allowing time to respond.

21. In-field repairs are made easily with available materials when necessary. This repair was made with a T shirt.
