  2. 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

  3. Reconfiguring Systems

  4. Changing the Paradigm Q Traditional Operation (Upstream Level Control) Distribution Efficiency 50-70% Typical

  5. Changing the Paradigm Q Modern Operation (Total Channel Control®) Distribution Efficiency Up to 90% demonstrated

  6. ~10% - 250GL ~8% - 200GL ~8% - 200GL Water Usage and Infrastructure Recovery Options An example - Victoria, Australia Metered Allocation To Irrigators ~1750GL Water used By Plant/Crops Actual Usage by Irrigators Diversions To Irrigation Districts Goulburn- Murray Water ~2500GL Scheduling/Automation On Farm Loss INFRASTRUCTURE REFORM TARGET Accurate Meters (100%) Meter Error Unaccounted For Water ~750GL TCC on Channels(100%) Outfalls By Comparison Melbourne’s Usage ~470GL Leakage & Seepage Lining (up to 80%) Evaporation Source: Water Savings in Irrigation Distribution Systems, Sinclair Knight Merz, 2000 Rubicon Systems Australia, based on trials in Central Goulburn District
