What is fatberg?

Fatberg is the term used when a sewage system is blocked by household waste. This waste can be from congealed fat, oil, wet wipes and nappies that have been flushed down the drain. As these items take longer to break down, they get stuck in the sewer system, blocking the drain pipes. This causes blockage and can even result in the pipes breaking.

How does this affect your drains?

Blocked drains can be caused by a range of reasons, one of these being a fatberg. The most common item to cause a fatberg is fat oil and grease. By putting these items down your drain, you can slowly cause a fatberg due to other substances (such as wet wipes) combining with the oil. The substances can no longer flow through your drain swiftly and can get caught and stuck in the drain with other non flushable objects. This can result in drain blockages

How to avoid fatberg?

The best way to avoid fatberg in your drains, is to ensure you are not disposing of items such as wet wipes down the toilet. You can also avoid throwing excess oil down the sink and instead oil can be emptied into disposable containers and once allowed to cool disposed of in the bin.

What is a fatberg, and how is it formed in drains?

A fatberg is a mass of fats, oils, grease, and non-biodegradable items that accumulate in sewer systems, particularly in large cities with high population densities. Fatbergs form when grease and oil are poured down drains or flushed into toilets, where they solidify and combine with other materials such as wet wipes, sanitary products, and food debris.
