I have a wood swing set I want to put up but my backyard is irrigated. How can I protect the swing set? - swing set plans/bluprints

I have a wooden swing that I use in my garden, but also water in the garden. How do I protect the legs of the red? Also, if you want to add damping to the earth, how can I do with irrigation?
