40 ton glob of fat removed from London sewers

A disgusting 40-tonne fatberg the size of a double-decker bus has been cleared from a London sewer by Thames Water engineers who pulled out some of it by hand.

The mass of fat, grease and other materials that weighed the same as three double-decker buses, was discovered earlier this year clogging up a sewer in Greenwich, the water company said.

It took three weeks for Thames Water workers to clear the 'disgusting' blockage which at points took up 80 percent of the sewer's capacity, using a combination of high-powered water jets to blast it loose and removing debris by hand.

Fatbergs are formed when fat, oil and grease are poured down sinks and drains and combine with items that should not be flushed down the toilet, such as unflushable wet wipes, nappies and cotton buds.
