Video footage shows the size of huge 'fatberg' discovered by London sewage workers last month.
The discovery of the so-called fatberg was made on 4 July, and according to Thames Water, who manage the city's sewers, it took three weeks to clear.
Footage of the giant lumpy mass, estimated to weight more than 15 tonnes, was released to the media on Tuesday (August 6) and work is now being carried out to repair the damage caused to the pipes in the English capital.
The fatberg, made up of festering food fat combined with wet wipes, reduced the sewer's working capacity to only five percent.
The sewer is in Kingston South of London, and the blockage was only discovered when residents in the area said they couldn't flush their toilets.
