My field lines only, not the tank, has roots that need to be killed. The most common treatment seems to be copper sulfate, and it's expensive. Salt is much cheaper(.50c/lb for table salt) and it will kill roots. With an access pipe at the output of the tank/input to field, anything can be dumped down it. Has anyone tried putting salt into the field lines?

Don't know but clean-out guy says salt is bad for concrete in line.

Roots don't seem to be a problem with my field although I had removed
trees too close to the tank drain line.

I heard salt was bad for concrete but field lines are free of concrete. The lines are surrounded by gravel but that should not be a problem.

Many trees have roots that only grow under the tree but other type trees can grow roots several hundred feet beyond the tree line. Sweet gum is like that and that's my problem. I killed the trees and the roots are still growing & putting up shoots. Spray the shoots with roundup, they die, but another shoot will pop up nearby.
