Tree roots in sump pit

Hey guys, My company doesn't do drain cleaning, so I'm coming to you guys. I bought a house last week, and checked the sump and tree roots were in it.. Guessing they came down drain tile. I'll look closer when I get home. You guys ever see this? If so, how did you deal with it ?
House was built in late 70s , so not sure if they had the same type of drain tile we have now.
