'Bus-sized fatberg' removed from London sewer

Britain's biggest ever "fatberg" has been removed from a London sewer.

Thames Water say a "bus-sized lump" of food fat mixed with wet wipes formed in drains under London Road in Kingston-upon-Thames.

It took three weeks to clear the mass and work is now under way to repair damage it caused underground.

Gordon Hailwood, a sewer contract manager for Thames Water, said if it had not been discovered in time, raw sewage could have started to spurt out of manholes across the whole of Kingston.

He warned of the dangers of "fatbergs," saying that Thames Water was trying to spread the message of "bin it and don't block it".
