Why are the Americans so interested in our sewers?

Don’t get me wrong – the articles are actually pretty interesting. Who knew Peter Bazalgette, the man behind BIg Brother in the UK, was so into sewers or that there’s such outstanding architecture at sewage treatment works? But why is there a daily series on London’s sewers on Slate this week? Are US readers really fascinated by London’s sewage system? Sewage systems in general? All aspects of UK or London life?

Odd. Very odd.
