I wonder if this is a nightmare or an interesting engineering problem for the removal crews.

Wouldn't very hot water or steam take care of it?  Maybe some good solvents?

Not as much fun as explosives, but better than digging it out.

"This observation, also, I have laid to heart, that they, who in matters of war seek in all ways to save their lives, are just they who, as a rule, die dishonorably; whereas they who, recognizing that death is the common lot and destiny of all men, strive hard to die nobly: these more frequently, as I observe, do after all attain to old age, or, at any rate, while life lasts, they spend their days more happily."  Xenophon

I wonder how much of this is due to water-saving techniques in GB.  I know a couple of cities in the U.S. have had to add water to their sewer systems to keep the stuff flowing properly.

Ed Norton, where are you when we need you?

High-pressure water jets will cut granite.  Hot water jets should slice that to pieces easily without needing extreme pressure equipment or solvents or a lot of drama.

A few years back, my wife and I toured the Brightwater sewage treatment plant in south Snohomish county, to see our $ 100/month sewer bill in action.  The tour guide made a big point about flushing wet wipes down the toilet and dumping oil/liquid grease into the sink was the bane of their existence, and they had elaborate traps to try and separate this out from the waste stream before it started the biological/chemical sewage treatment.

Heat would work, assuming you divert and capture the runoff. Because otherwise if you melt it down and just let it continue on down the sewer, you'll have the same problem again in just a few hundred meters further down.

Personally, I'd love to have a high concentration spray of Sodium Hydroxide, and just saponify the fat away. And you'd get a two-fer, all the soap suds would clean the sewer downstream too.

It's probably already partially saponified into calcium soap.  That's why it's so concrete-like.

From what I read, the issue isn't breaking it up, it is capturing and hauling the tons of it all off so it doesn't get washed farther down the system just to solidify yet again.

Does Great Briton not have any immigrants from SE Asia?  I'm sure some of the more disreputable of them could take of that mess right quick and make a profit selling it back to the pubs and fish & chip joints.

It's also worth noting that there is a "Bin it don't block it" campaign to discourage flushing the types of waste that form fatbergs.

I'm assuming "Bin it" means throw it away. Is "block it" their way of saying flush it?

The Brits don't have "waste baskets" -- they have "rubbish bins."

Bin it - throw it in the garbage bin.

don't block it - don't block up the sewer by flushing it.

I see. I was thinking afterwards that maybe they meant it in that way.
