Melvyn Bragg and guests discuss the stench from the River Thames in the hot summer of 1858 and how it appalled and terrified Londoners living and working beside it, including those in the new Houses of Parliament which were still under construction. There had been an outbreak of cholera a few years before in which tens of thousands had died, and a popular theory held that foul smells were linked to diseases. The source of the problem was that London's sewage, once carted off to fertilise fields had recently, thanks to the modern flushing systems, started to flow into the river and, thanks to the ebb and flow of the tides, was staying there and warming in the summer sun. The engineer Joseph Bazalgette was given the task to build huge new sewers to intercept the waste, a vast network, so changing the look of London and helping ensure there were no further cholera outbreaks from contaminated water.
