I've bee thinking about starting a company where I fish roots out of your sewer and identify the plant (by sequence if necessary) that you have to kill so your sewer doesn't collapse as soon as it otherwise would.
$100 to stave off that $10000 sewer replacement for a few years would be worth it to a lot of people
