What Is a Fatberg?
A fatberg is a congealed mass of fat, oil, grease, and non-biodegradable items (especially wet wipes) that builds up inside drains and sewers. The term became famous after massive fatbergs were discovered in London's sewer system, but smaller fatbergs regularly form in residential and commercial drainage, causing blockages and backups.
Most teams review what is a fatberg? when live project risk needs turning into a clear technical decision with practical next steps.

When to consider this guidance
Teams usually investigate what is a fatberg? when early warning signs start affecting reliability, compliance, or project timelines. This is often the point where decision makers move from observation into scoped technical action.
Common warning signs
The symptoms below are the most common triggers we see before diagnosis and repair planning.
- Fats, oils and grease (FOG) solidify when they cool inside pipes
- Wet wipes, cotton buds and sanitary items bind with the grease
- The mass grows over time, gradually restricting pipe flow
- Eventually the fatberg blocks the pipe entirely
- Commercial kitchens are the biggest contributors to fatberg formation
How this is usually carried out
CCTV surveys reveal fat buildup inside pipes — from thin grease coatings to pipe-blocking masses. We assess the extent of the buildup and determine whether simple jetting will clear it or whether more intensive cleaning is needed.

How we approach the fix
We clear fat deposits using high-pressure jetting with hot water and specialist descaling nozzles. For severe buildup, electro-mechanical cutting equipment breaks down the mass before jetting flushes it away. We advise on prevention measures to stop fatbergs reforming.
What affects cost and complexity
Cost and complexity usually depend on access constraints, total scope, existing condition, and whether related works need to be coordinated in the same programme window.
How delivery is structured
We keep delivery structured so scope, sequencing, and sign-off remain clear.
