You both are confusing storm drains and sanitary sewers. In the developed world they are two separate systems. Speaking as a plumber of 25 plus years, I can say without a doubt that the largest cause of sewer backups is flushable wipes and tampons. Neither of which should be flushed down a toilet.

Thank you for the explanation. It is amazing how the marketing claims that wipes are “flushable” can cause such havoc to the taxpayer. You don’t hear the greenies going after this.
