15. Demo run ceremony

16. Scope and scale of the demo 10% of full capacity operation 90 day duration Ensured a valid test at a reasonable cost Demonstration run began on March 1 All objectives have been met

17. Added success Government, water users and conservation interests can find common ground Heightened interest in potential alternative uses of the plant

18. Alternative uses of the plant Process a different feed water Produce potable water

19. The challenge Where does this plant fit into the water supply picture for the Lower Colorado River? How do we best use this asset?
