Grease & Fatbergs – Prevention

How fatbergs form

Grease, oils, and fats cool and solidify in pipes. When combined with wipes, sanitary items, and other debris, they bind together into solid masses that restrict flow and cause flooding.

• Fats and oils solidify as they cool in pipes
• Wipes and sanitary items don't break down
• The combination creates rock-hard blockages
• Build-up is gradual but damage is sudden

Prevention tips (households)

• Wipe pans and plates with paper before washing
• Collect used cooking oil in a container for disposal
• Never pour fats, oils, or grease down sinks
• Only flush toilet paper—no wipes, even "flushable" ones
• Use sink strainers to catch food debris

Prevention tips (businesses)

• Install and maintain grease traps/separators
• Regular professional servicing of traps
• Staff training on grease disposal
• Hot water + detergent doesn't solve the problem—grease just moves downstream

Why prevention matters

Clearing fatbergs often requires high-pressure jetting or even excavation. In severe cases, hardened fatbergs can damage pipe structures. Simple daily habits prevent thousands in repair costs and avoid backups into your property.

Signs of grease build-up

• Slow-draining sinks or toilets
• Gurgling sounds from drains
• Foul odours from waste pipes
• Recurring blockages despite clearing

If you spot these signs, a CCTV survey can confirm grease build-up and guide cleaning.
