Overview


Irrigation is key to producing more food


Irrigation consumes approximately 70% of
the world’s water


Gravity channel systems are the dominant
delivery mechanism


unlikely to change


Operating technology has changed little
since the early civilizations
-

inefficient


Modern infrastructure and control
engineering can increase distribution
efficiencies from ~50
-
70% to ~70
-
90%


This realizes massive water savings
