Fats and furious: A 100-tonne 'fatberg' found in London sewers

Move over Godzilla, there's a new heavyweight in East London—and it's lurking beneath your feet. Thames Water has uncovered a gargantuan 100-tonne fatberg, stretching a jaw-dropping 100 meters through a Whitechapel sewer.

Made of grease, oil, congealed fats, this semi-solid menace is set to keep crews busy for weeks, reports the BBC.

Dubbed affectionately as "the grandchild" of a legendary 2017 fatberg—an even bigger 130-tonne behemoth that stretched 250 meters—this latest plumbing monstrosity is a grim reminder of what happens when leftover lasagna meets careless flushing.

Luckily, East Londoners aren't facing tap-taps of doom just yet; the sewer is only partially blocked. But make no mistake: these fatbergs are serious business, costing the city tens of millions of pounds to slice, dice, and haul away.

Think of it this way: if London's sewers were your arteries, a fatberg would be cholesterol on steroids. One day it's a minor clog of leftover gravy, the next it's a solid mass that demands expensive surgery—or in this case, backhoes, hoses, and heroic engineers.

Authorities are pleading with the public to do their part this December and January, when fatbergs peak like winter colds:

• Scrape food scraps into the bin, not down the sink.
• Catch solids with sink strainers.
• Trash liquid fats, gravy, cream, and oils—don't pour them down the drain.

So next time you're tempted to wash last night's curry down the sink, remember: you could be feeding the next Whitechapel monster. And while it may not roar, it will definitely block.
