How Fatbergs Have EXPLODED From 15 Tonnes to 100 Tonnes in 11 Years
Originally published September 2014 | Updated November 2025
This article is all about the biggest ever fatberg and how the fatbergs have grown from 15 tonnes when I first wrote this article back in 2014.
To fatbergs as big as 100 tonnes now in 2025.
…
Now, 11 years later and instead of our water companies getting on top of the problem, it’s grown and growing into Britain’s biggest fatberg problem.
Back in 2013-2014, I was shocked when Thames Water discovered a 15-tonne fatberg in Kingston, Surrey.
It was the size of a bus. I thought: “How the hell does this happen?!”
Fast forward to 2025:
Fatbergs haven’t gotten smaller. They’ve gotten MASSIVE.
That’s nearly 7 times bigger than the “shocking” fatberg from 2013.
Let that sink in: In just 11 years, Britain’s fatberg problem has exploded from 15 tonnes to 100 tonnes.
And it’s all because of one thing: wet wipes.
So, do you use wet wipes when you go to the toilet?
If you do, I’m pretty sure you don’t put the used wet wipe into the bin. You obviously throw it down the toilet, right?
Well, you might want to think again.
If you’re one of a growing number of people who are using wet wipes in search of a better clean than the ancient invention of toilet paper, then you are NOT alone. But the problem has got so bad that the water companies are getting tough on fatbergs and coming after wet wipe users who clog the sewers.
What Happened With The Biggest Ever Fatberg (2013)
Back in 2013, this story shocked Britain:
A gigantic fatberg — a bus-sized lump of wrongly-flushed festering food fat mixed with wet wipes — formed in drains under London Road in Kingston, Surrey.
Had it not been removed, it could have led to sewage flooding many homes, streets and businesses in the leafy London suburb.
Gordon Hailwood, waste contracts supervisor for Thames Water, said at the time:
“While we’ve removed greater volumes of fat from under central London in the past, we’ve never seen a single, congealed lump of lard this big clogging our sewers before.”
“Given we’ve got the biggest sewers and this is the biggest fatberg we’ve encountered, we reckon it has to be the biggest such berg in British history.”
“The sewer was almost completely clogged with over 15 tonnes of fat. If we hadn’t discovered it in time, raw sewage could have started spurting out of manholes across the whole of Kingston.”
Back then, 15 tonnes was considered MASSIVE.
The blockage was discovered after residents in nearby flats complained they couldn’t flush their toilets.
CCTV investigations found the mound of wet wipes and fat had reduced the 70 x 48cm sewer to just five per cent of its normal capacity.
Fast Forward to 2025: The Feltham Fatberg (100 Tonnes!)
If you thought 15 tonnes was bad, buckle up.
In 2025, Thames Water discovered a 100-tonne fatberg in Feltham.
That’s 100,000 kilograms of congealed wet wipes, fat, and sewage.
For perspective:
❌ 15 tonnes (2013) = Size of a bus
❌ 100 tonnes (2025) = Nearly 7 buses worth
The 2025 Feltham fatberg:
❌ Took over a month to clear
❌ Cost over £220,000 to remove
❌ Required specialized equipment
❌ Blocked sewers serving thousands of homes
❌ Nearly caused massive sewage overflow
And it’s just ONE of 28,899 rag blockages Thames Water dealt with in 2025 alone.
Why Have Fatbergs EXPLODED From 15 to 100 Tonnes?
Simple answer: More people are using wet wipes.
Here’s why:
Back in 2013-2014:
- Wet wipes were growing in popularity
- “Flushable” wipes were new on the market
- People trusted the marketing
By 2025:
- Wet wipe usage has EXPLODED
- “Flushable” claims are everywhere (but they’re lies)
- More people than ever are using them daily
- Result: 3.8 billion wet wipes removed from London sewers annually
The math is simple:
More wet wipes flushed = Bigger fatbergs = More sewage problems = Higher water bills for everyone
The Real Reason People Use Wet Wipes (I Understand)
I feel very sorry for wet wipe users.
I know toilet paper is often very painful and rarely gets you properly clean.
Who wants to walk around and try to continue their daily work agenda with a less-than-perfectly clean rear end?
Nobody. That’s the honest truth.
People use wet wipes because toilet paper fails.
As we demonstrated in the comparison between bidet sprayers vs toilet paper, dry paper simply doesn’t clean properly.
So people reach for wet wipes, hoping for better cleanliness.
The problem? Wet wipes don’t break down like toilet paper. They create fatbergs.
The Fatberg Crisis: 2013 vs 2025
Let’s compare what’s changed in 11 years:
2013 Fatberg Crisis:
❌ 15-tonne fatberg was “biggest ever”
❌ Isolated incidents
❌ Water companies starting to worry
❌ The public is mostly unaware
2025 Fatberg Crisis:
❌ 100-tonne fatberg is a new record (but won’t be for long)
❌ 28,899 rag blockages in one year
❌ £18 million spent annually clearing blockages
❌ Thames Water is going hard after wet wipe users
❌ Record £2.5 million fine for sewage management failures
❌ Public anger at raw sewage in rivers
The fatberg problem has become a CRISIS.
What Thames Water Said Then vs Now
Gordon Hailwood (Thames Water, 2013):
“Homes and businesses need to change their ways. When it comes to wet wipes, please remember: ‘Bin it – don’t block it.'”
Thames Water (2025):
“We’re spending £18 million annually removing wet wipes from sewers. This is unsustainable. We’re taking enforcement action against persistent offenders.”
Translation: They’re getting serious about stopping wet wipe flushing.
The “Flushable” Wipes LIE
Here’s what’s changed between 2013 and 2025: NOTHING.
“Flushable” wet wipes still don’t break down like toilet paper.
The marketing claims: ✅ “Flushable” ✅ “Safe for sewers” ✅ “Biodegradable”
The reality:
❌ Takes months/years to break down (if ever)
❌ Causes fatbergs
❌ Clogs sewers
❌ Creates environmental disasters
As I wrote back in 2014, and as is still true in 2025: The wet wipes industry is lying to you.

The Fatberg Problem Will Keep Getting WORSE
Here’s the uncomfortable truth:
Unless something changes, fatbergs will keep getting bigger.
Why?
Because more people are discovering that toilet paper doesn’t clean properly, so they’re turning to wet wipes.
The progression:
2013: 15-tonne fatberg (shocking!)
2025: 100-tonne fatberg (crisis!)
2030: ???-tonne fatberg (catastrophe?)
It doesn’t have to be this way.
What Is The Alternative To Wet Wipes?
If you do not want to be part of the wet wipes problem but want a much cleaner rear end, there IS a better alternative.
Look, let’s face it: You can’t be blamed for wanting to be properly clean after using the bathroom.
But wet wipes are NOT the answer.
Water is.
But you can’t jump in the shower after every toilet visit.
However, you CAN get “shower fresh” clean with The Bum Gun bidet sprayer.
Why The Bum Gun Solves The Fatberg Problem
Think about it:
Wet wipes exist because toilet paper fails.
But The Bum Gun makes wet wipes unnecessary.
Here’s how:
✅ Water pressure washes you properly — genuinely “shower fresh” clean
✅ No wipes needed — water does the job completely
✅ Nothing goes down the drain except water and normal waste
✅ Zero contribution to fatbergs — no solid materials clogging sewers
✅ Saves money — no buying £3-4 wet wipe packages weekly
The Bum Gun eliminates the entire reason people use wet wipes in the first place.

The Economics: 15-Tonne Fatberg vs 100-Tonne Fatberg
Let’s talk about what this costs YOU.
2013 Kingston Fatberg (15 tonnes):
- Removal cost: £50,000+
- Repairs: 6 weeks
- Road closures: Multiple weeks
- Cost passed to customers: Yes
2025 Feltham Fatberg (100 tonnes):
- Removal cost: £220,000+
- Repairs: Over 1 month
- Disruption: Massive
- Cost passed to customers: Yes
Who pays for fatberg removal?
You do. Through higher water bills.
Thames Water spends £18 million annually clearing wet wipe blockages.
That £18 million comes from customers’ water bills.
So every time you flush a wet wipe, you’re contributing to:
❌ Higher water bills for everyone
❌ Sewage overflows polluting rivers
❌ Massive environmental damage
❌ Infrastructure strain
Or you could install The Bum Gun for £95 once and eliminate the problem entirely.
What If Everyone Switched From Wet Wipes to Bidet Sprayers?
Imagine this scenario:
If just 50% of wet wipe users switched to bidet sprayers like The Bum Gun:
✅ Fatbergs would reduce by 50%
✅ Thames Water would save £9 million annually
✅ Sewage overflows would decrease dramatically
✅ Water bills could stabilize or even decrease
✅ Rivers would be cleaner
If 100% switched?
The fatberg crisis would essentially END.
That’s the power of proper bathroom technology.

From 15 Tonnes to 100 Tonnes: A 11-Year Warning Ignored
Here’s what frustrates me:
Back in 2014, when I wrote the original version of this article, the 15-tonne fatberg was a WARNING.
Everyone should have thought: “Wow, we need to stop flushing wet wipes.”
But what happened instead?
People kept flushing wet wipes. The problem got WORSE. Fatbergs got BIGGER.
And now, 11 years later, we have 100-tonne fatbergs.
How big will they be in another 11 years if nothing changes?
200 tonnes? 500 tonnes?
At some point, the infrastructure will fail completely.
The Solution Is Simple (But Requires Action)
Here’s the bottom line:
Option 1: Keep using toilet paper (feels unclean) → Switch to wet wipes (feels cleaner) → Flush them → Create fatbergs → Pay higher water bills → Pollute rivers
Option 2: Switch to The Bum Gun → Get “shower fresh” clean → No wipes needed → No fatbergs → Save money → Help environment
Which makes more sense?
What Is The Alternative To Wet Wipes?
If you do not want to be part of the wet wipes problem, but want a much cleaner rear end, there IS a better alternative.
Look, let’s face it, you can’t be blamed for wanting to be properly clean after using the bathroom.
But wet-wipes are NOT the answer.
Water is…
