i think you can "train" your tomatoes over multiple generations to be able to survive with nearly no additional water. they will build extremely long roots, and you don't have to water them so often as you do with normal tomato plants.
but the seeds you buy are coming from tomatoes that where never short on water, so they need water and will not build long roots.
