Now, there may be baseball and basketball (rooting for the Maloof family).

That will solve the root cause.

If it is a more recent situation look for the root cause and try to figure it out before you let them go. 

Most use what's called a Veeder-Root system for that.There are/were quite a few single-wall stainless tanks in use. 

I also did a sewer scope as well that showed that the roots has gotten into the sewers and needed to be replaced immediate.

I don't do root canal on myself either! 

Personally in my experiences we have worked with many Section 8 tenants and we have learned to be able to as you stated screen them a little bit better and root out the good from the bad so that you do have a good experience with a Section 8 tenant.

I also did a sewer scope as well that showed that the roots has gotten into the sewers and needed to be replaced immediate.

Now we were out there in April with a plumber due to roots in the sewer line, the plumber and I were there for around 4 hours he ran a camera through the lines and cut out all the roots and then ran the camera through it again and the line was clear.

Many families, including my wife’s family, migrated here and laid roots in the early to mid-1900s.
