Fatbergs: The data behind the growing phenomenon

Have you ever heard of a fatberg? Keep an eye on the news over the coming months and the chances are you will.

Utilities companies and drainage firms are coming across mammoth fatbergs on an increasingly regular basis and they are posing a huge problem to our waterways and marine life.

Here, we take a look at the statistics and facts behind this growing phenomenon.

What is a fatberg?

A fatberg is the equivalent of an iceberg, found down the sewer and consisting of a congealed, solid mass of fats, oils and grease (FOG) poured down the drain by the public.

The blockages are also made up of items that are regularly flushed, such as sanitary products, wet wipes, condoms and cotton buds.

For more information, take a look at our fatberg removal and cleaning page.

Famous Fatbergs

The most famous fatberg to date is probably the mammoth Whitechapel fatberg of 2017, which weighed 130 tonnes.

Its story was seen by more than 1 billion people around the world, and a piece of the fatberg now sits on display in the Museum of London, with a live webcam streaming its gradual disintegration.

But there are hundreds more fatbergs lurking beneath the ground all over the UK and we are tackling them daily. They are incredibly difficult to remove and many of them have to be destroyed by chipping away at the mass by hand.


Fatberg data and statistics


We are on a mission to educate the general public about these monsters so that they stop creating them in the first place.

As part of our campaign, we gathered original data about public opinion on issues surrounding fatbergs. Please note: this is taken from a 2018 survey; for the latest 2019 survey results and data please visit this page.

The findings of our survey are included below and we have made these statistics open to the public so you can use them as you see fit, ensuring Lanes Group plc is credited.
