You carry it.
Or if you have money to spend on a system and sense enough to set it up and desire to do so you pump it.
But it's been 90+ most days for at least a month here and I haven't watered any plants since I put them in the ground in May. They aren't in particularly moist areas either.
So as long as you don't have them in pots you shouldn't have to water too awful much. Putting in the effort of digging a large hole early in the season pays off 100x later on in the year in the effort it takes to water. I have a couple container plants too and even the ones who's containers are fully shaded need watered every 3-4 days. 5gal containers.
