With a chunk now double cased (thankfully) and taking centre stage in the Museum of London, many thought that would be end of the problem.
Now multiple discoveries across the country suggest that fatbergs could become a more regular problem for UK water companies despite common warnings to customers not to flush fats, oils and grease (FOG) down drains.
A fatberg is defined as “a large mass of fat and solid waste that collects in a sewer system”, the word fatberg was even announced as one of 533 new words to be added to the Merriam-Webster dictionary. Fatbergs are huge masses of solid waste that clog up sewage systems. They are made up of congealed fat, grease and oil, as well as wet wipes, sanitary towels and nappies that have been flushed down the toilet. Water utilities can spend millions every year clearing blockages as a result of homeowners and businesses pouring fats, oils and greases (FOG) unnecessarily down drains.

South West Water said it spends an additional £4.5 million every year on clearing blocks from its 17,000km sewer network and discovered the fatberg during routine maintenance.
Andrew Roantree, director ofwastewaterand South West Water, said: “It shows how this key environmental issue is not just facing the UK’s cities, but right here in our coastal towns.
The fat was removed by the water utility as part of work on a £2 million investment project Victorian brick sewer in Mermaid Quay in Cardiff Bay.
According to the utility, the removed congealed mess of fats, oils, grease and wipes weighs the equivalent of 133 African bull elephants.
Steve Wilson, managing director of Welsh Water, said: “Work on the Mermaid Quay scheme is definitely proving to be a challenging one due to the large volume of fat, grease and oil which had built up in the sewer and caused a number of sewer collapses along Bute Street and Stuart Street. While we know this is a busy area, the sheer volume of this material we’ve taken out of the sewer shows the scale of the issues we are tackling.”
Bin it mantra
Wales and the south western England to one side,Thames Water, the utility servicing London has become known globally for its relationship with fatbergs.
2013年佤邦进行肿块s discovered in Kingston upon Thames, at the time being labelled as “Britain’s biggest ever fatberg”.
Four years later and the Whitechapel fatberg – 10 times the size – was discovered. At the time CCTV camera inspections showed sewer to be totally blocked by the fatberg which was 3.5 metres deep below ground for 250 metres.
尽管重复了它的'垃圾桶 - 不要阻止它'口头禅，Fatbergs继续是一个挑战Thames Water, with estimates suggesting there are 10 large fatbergs in London right now, with hundreds of smaller ones across the country.
Fat traps and wipes
One of the challenges is the inheritance of a network of underground sewers built 150 years ago that are not designed for what’s flushed away today, including wipes.
根据BBC，研究Thames Watermapped the location of fatbergs and restaurants. The result showed that you’re chances of being flooded with sewage are eight times higher if you live within 50 metres of a fast-food restaurant.
