At 230 metres long and weighing 130 tonnes, the Whitechapel fatberg won’t be forgotten by the team that tackled it.

And now it won’t be forgotten by anyone else, either, thanks to a special manhole cover installed to commemorate the occasion.

Alex Saunders, Thames Water waste network manager, said: “The Whitechapel fatberg revolted and fascinated everyone, and got people everywhere talking about what happens next to their waste.

“It certainly showed that out of sight isn’t gone forever – and now their heroic work in awful conditions will be remembered with this new commemorative manhole cover.”

Part of the fatberg, which was discovered a year ago, is now on display at the Museum of London, where a ‘fatcam’ is constantly streaming it to the world.

And look out for Fatberg: The Musical, which could be coming to a theatre near you - a script based on the iconic lump of sewer waste is being worked on.
