Those ‘flushable’ wipes sure are a gross problem. Combined with nappies (diapers), condoms, tampons and congealed fat, they can stick together to form a gargantuan ‘fatberg’, like the one currently clogging up a section of London’s sewers.

At 130 tonnes (143.3 tons) and covering 250 metres (820 feet), it’s the biggest ever unearthed in Britain.

That’s as heavy as at least 20 African elephants, and as long as 2.5 football fields.

It was discovered earlier this month during a routine sewer inspection, and now workers are spending seven days a week trying to break it up so that it doesn’t flood the streets of Whitechapel in East London with sewerage.
