Since i will be put my pipes under ground about a foot and a half would i have a problem if someone stepped there?

I though it might move the pipe but i wasn't sure.

That depth is fine for foot traffic.

i would back fill around the pipes with gravel or sand around the pipe then top soil then turf over the top
