It may be significant that in the UK, which has a cooler summer than Georgia and therefore less evapotranspiration, the Abstraction Charge for certain types of agriculture (spray and trickle irrigation, and water for horticulture) incurs a higher charge than that for any other purposes, due to its high “loss factor” (Winpenny, 1998). The rates should bear some relation to typical consumptive losses, and should be at a level high enough to register with abstractors when they consider how much water to withdraw. This conclusion is timely given the active consideration being given to the development of a series of hydropower projects in Georgia.
