Conservation is by far the least expensive of the available options, in large part because newer technology hasn't been implemented on a widespread scale. This could easily be the difference.You're probably right, in the present on a large scale anyway. Shifting priorities may change that if better technologies don't.
Spray irrigation here in the arid West is very inefficient. It's not uncommon to lose over 70% of the water being sprayed on the crops to evaporation- and farming is the biggest user of water resources by far.
