The answer isn't tree roots. "Wastewater officials across the country have been trying to spread the message that not just anything can go down the toilet, and they have recently taken aim at wipes." Yes the omnipresent 'wipes'. Wipes are everywhere and used for everything these days. Everything from babies to cleaning bacteria off of kitchen counters to cosmetic removal.
And more often than not they're being flushed down toilets which is causing a huge back-up. These wipes do not break down as toilet tissue does and for that matter kleenex doesn't really loose it's shape either.
We should rethink how we dispose of the wipes to save ourselves the headache of sewer backups. I do draw the line at believing one other item the story claims is flushed down toilets and that is kitty litter. If you flush kitty litter you may just deserve the arrival of Router Rooter.
