Of late the dispatches from London have concerned a gigantic “fatberg” that has completely blocked one of the main sewer channels under Whitechapel. That the capital’s Victorian sewer system is just now reaching capacity is due to the foresight and engineering genius of Mr. Joseph Bazalgette who was given the mandate to update London’s sewer system following a series of cholera epidemics in the 1830s and 1840s.
When calculating out the dimensions of the pipes, he considered the highest population density producing the most amount of sewage. Then he reportedly said, “Well, we’re only going to do this once and there’s always the unforeseen,” and doubled the diameter. It is estimated that Bazalgette’s prudence bought an extra 50 years of life to his brick-lined sewage channels, so that only now is London needing to upgrade its system.
A very informative article in Prospect Magazine investigates the genesis of the Fatberg in more detail.
