LONDON — Sewerage workers have removed what they believe to be Britain’s biggest ever “fatberg” — a festering lump of flushed-away fat and other residues — from a London sewer in a special operation that took 10 nights.
The blockage was discovered on July 17 when residents of the affluent southwestern suburb of Kingston upon Thames reported trouble with flushing their toilets.
A video posted online Tuesday shows the moment a remote camera discovered the enormous lump, which weighed as much as two fully grown African elephants.
“The sewer was almost completely clogged with over 15 tons of fat,” said Gordon Hailwood, water contracts supervisor for the local water utility, Thames Water.
