         | A very easy, reasonable step would be to heavily tax wipes

         | It's trivial to stop the fatbergs caused due to flushable wipes

         | _why_ people use flushable wipes instead of spending time and
         | money in celebrity campaigns [1] against them.
         | 
         | The conclusion is obvious - wiping with dry toilet paper is an
         | inefficient, unhygienic, and sometimes painful way of cleaning
         | yourself after defecation. Hence, people use wet wipes to "feel
         | fresher", as the advertisements euphemistically put it.
         | 
         | The solution is also quite straightforward - go all the way and
         | replace most uses of toilet paper with bidets or washlets,
         | following the lead of smart nations like Japan. Wet wipe usage
         | will automatically plummet. City planners all over the world
         | should be running campaigns promoting bidet usage and
         | partnering with washlet companies instead of sternly wagging
         | their fingers at wet wipe users.

           | This is inaccurate as a generalization - in the three
           | jurisdictions I've worked in, they're round if they're newer
           | than ~1990, and mix of round and square (or two triangles
           | that go together to make a square) if they're older than
           | that. The frame and cover are replaced independently from the
           | MH structure itself so the cover doesn't tell you anything
           | about the makeup of the structure.
