It’s probably safer to watch this one a while after you’ve eaten – just a forewarning. The aptly named “Fatberg” autopsy places channel 4 camera crews into sewage plants to uncover the startling build ups which have started emerging known as, well, fatbergs. The one-off documentary is presented by Rick Edwards and Carla Valentine.
Given all of the grease and oil, not to mention tonnes of litter, which makes its way into our sewer systems each day, Channel 4 sends people behind the scenes to investigate the alarming mountains of rubbery fat which, left unchecked, can cause massive blockages and hence be seriously detrimental to public health and hygiene. One such build up, removed and affectionately named “total monster” by health official is in the east end, extended for 250 meters – 10 longer than tower bridge – and weighed 130 tonnes in total. However the size and weight of such a colossal glut of refuse and fat was not the only disturbing secret to arise from the sewers under our feet; the rancid blockages have given way to anti-biotic resistant super bacteria.
