I've discussed ventilation for toilets and tube stations, but can't forget the sewage 'stench pipes' which also adorn our streets. Believe it or not, I'm not using the word 'adorn' sarcastically: some examples are even listed.
There's a stink pipe on Watson's Street, Deptford which has a moderately ornate base topped by a long, slender and plain pipe. It's pretty typical of the Victorian work of its manufacturer, Ham Baker. Indeed, this particular design seems to have been popular: Faded London has a very similar pipe in Jamaica Road.
Ham Baker are now based in the Midlands but some of their older metalwork calls them 'Ham Baker, Westminster'. Indeed, Frederic Ham was listed in 1905 as a member of the Institution of Mechanical Engineers; his firm's address was 13 Grosvenor Road, Westminster. They also made all sorts of other items including fire hydrants and manhole covers; still in existence today, they now specialise in "innovative products for the water and waste water markets", so the sewage aspects of the business seem to have stuck!
What was the purpose of such pipes? They offered an escape route for built-up gases, particularly hydrogen sulphide gas which was corrosive and could otherwise damage the sewers. (Again, Faded London has more information.) This was particularly important where the sewage was travelling long distances or the flow was slow. However, vital as venting the gases might be, nobody wanted to smell them as they escaped: hence the great height of these pipes.
Given their mundane, even unappetising, role it's a tribute to the nineteenth-century appreciation of engineering that these pipes nonetheless enjoy some ornamentation. Although disregarded or mistaken for broken lamp posts, they are in their quiet way monuments to Victorian civic pride.
