A ‘Fatberg’ as Heavy as 11 Double-Decker Buses Found in the Sewers of London

Sep 13, 2017

A monster 'fatberg' made up of congealed fat, wet wipes, nappies and condoms has been found clogging up London's sewers.

Thames Water, the company responsible for the waste and water of London, shared pictures of the 820-foot blockage on Tuesday saying that it would take three weeks to remove.

They added that it weighs 130 tons, about the same as a blue whale or 11 of London's double-decker buses, and is longer than one of the capital's most famous bridges, London Bridge.

"It's basically like trying to break up concrete," Matt Rimmer, the company's head of waste networks, told the BBC. He added that the waste was avoidable and that people should bin waste like fat, oil and grease instead of washing it down the sink.

Eight workers will use high-pressure hoses to break up the mass, suck up the pieces into tankers and take it to a recycling site elsewhere in the U.K.
