What is a fatberg?

Brace yourself! A fatberg is a sewer blockage made up of cooking oil, tampons, condoms, wipes and other items that should never be flushed in the first place. All these items are small enough to make it past the u-bend but they congeal together to form rock-hard blockages further down the line that can require a drill to shift. They can grow to gargantuan proportions, causing costly and very unpleasant damage. Prepare yourself... images and video follows. When a sewer is completely blocked by a fatberg, it backs up and overflows. This sends sewage and detritus like tampons flowing into rivers and natural waterways, ending up on the beach. The Marine Conservation Society found 20 tampons, pads or wipes per 100m stretch of beach during their annual beach clean up in 2016. Read our letter in The Guardian newspaper about this! The overflow can sometimes be closer to home: on the high street, in your garden or even in your bathroom. The UK's water companies spend an annual £88m per year clearing fatbergs and repairing the damage they cause. Not only do the resulting roadworks cause inconvenience but the price is inevitably passed on to householders in their water bills. Here's a mere armful of fatberg, fresh from the sewer: fatberg


This problem is found globally, with fatbergs and sewage pollution being reported right round the world. So we're launching #FatbergWatch, to keep an eye on these monstrosities growing quietly underground and help rally support for their prevention. At FabLittleBag, we're supporting water companies in their campaign to ensure that only the 3 P's are flushed: pee, poo and paper. The disposal of other "unflushables" is made much more pleasant with a FabLittleBag, encouraging better binning. Here is our #FatbergWatch report on recent fatbergs, which we keep updated.
