Definition
Meaning
A large, solid mass formed in a sewer system from non-biodegradable waste like cooking fat and oils, congealed with flushed items like wet wipes, diapers, and sanitary products.
A metaphor for any large, obstructive, or problematic accumulation of waste or undesirable materials, especially those resulting from irresponsible human habits and poor waste management.
Linguistics
Semantic Notes
A portmanteau of 'fat' (grease) and 'iceberg'. It suggests something large, hidden, and dangerous. The word carries strong negative connotations related to pollution, urban decay, and social irresponsibility.
Dialectal Variation
British vs American Usage
Differences
Term originated and is predominantly used in UK media and municipal contexts. In the US, 'sewer blockage' or 'FOG (fats, oils, and grease) blockage' are more common technical terms, though 'fatberg' is increasingly understood.
Connotations
Both share the same core meaning. UK usage often carries a tone of public health scandal and municipal challenge. US usage is more likely to be purely descriptive or technical.
Frequency
Far more frequent in UK English, especially in news headlines. Gaining some traction in North American environmental reporting.

- Avoid direct translation as 'жировой айсберг' which sounds odd. Use technical terms like 'засор канализации из жира и мусора' or the borrowed term 'фатберг' (becoming known in specialist contexts).
Common Mistakes
- Spelling: 'fatburg' (incorrect). Pronunciation: stressing the second syllable (fa-TBERG). Using it for any small drain clog.

FAQ
Frequently Asked Questions
While blockages from grease are old, the scale and solidity of modern fatbergs are exacerbated by the widespread use of non-biodegradable wet wipes and sanitary products, which bind with fats to form concrete-like masses.
Yes, once removed and broken up, the fat can sometimes be converted into biodiesel, and other materials may be processed, though it is a complex and costly procedure.
One of the most famous was the 'Whitechapel fatberg' in London in 2017, weighing approximately 130 tonnes and stretching over 250 metres. However, large fatbergs are reported in many major cities worldwide.
Never pour cooking fats, oils, or grease down the drain. Scrape food scraps into compost or rubbish bins, and do not flush anything besides toilet paper. Even products labelled 'flushable' often do not break down quickly enough.
