You probably saw mention of Fatberg; it was all over the news feeds yesterday. But just in case…
You know what an iceberg is. A Fatberg is a 250 meter long, 130 ton solid mass of congealed fat, wet wipes, diapers, oil and condoms that is blocking a London sewer. Removing it will be a major public works project.
Fatbergs form because people throw things into the sewage system that shouldn’t go there. I’ll bet a lot of older cities have brewing Fatbergs that just haven’t gotten big enough to gum up the underground system.
I think this is the very definition of “urban gross.”
