UK crews work to break apart 'monster' fatberg blocking London sewer 

It’s often tempting to throw items like grease and wet wipes down the sink or in the toilet, but here’s one very good reason to not do that -- fatbergs.

The masses form when such products end up in the wrong places, typically sewers, and a neighborhood in London is now dealing with one that’s the length of roughly two NFL football fields.

Weighing in at roughly 130 tons and being compared to a giant chunk of concrete, the mass is expected to take three weeks to break up, according to the BBC.

London's sewer system and its history of 'fatbergs'
TO GO WITH AFP STORY BY ROBIN MILLARD Sewer technician Tim Henderson, a 'flusher' shovels the fat as he works in the intersection of the Regent Street and Victoria sewer in London on December 11, 2014. Every day beneath the streets of London, sewer cleaners are fighting a grim war against giant 'fatbergs' clogging the system. Congealed fat is blocking up the Victorian sewers and the problem is to get worse at Christmas. An extra two Olympic-sized swimming pools of turkey fat will be tipped down the drains during the festive season. There are 80,000 fatberg blockages a year, costing Thames Water customers �1 million ($1.6 million, 1.3 million euros) each month to tackle. The company urges people people to dispose of their cooking oil and fat properly. 'Bin it, don't block it' is their message.
