Peter Bazalgette is the great-great-grandson of Victorian civil engineer Sir Joseph Bazalgette. A third cousin is Edward Bazalgette who directed and produced the 2003 documentary "The Sewer King" which charted Sir Joseph Bazalgette's design and engineering of the London sewers. Peter Bazalgette presented a later television show for Five, called "The Great Stink", and chaired the Crossness Engines Trust raising £4.5 million to restore the magnificent Victorian pumping station built by his ancestor. An old joke is that where Joseph Bazalgette was responsible for removing ordure from London's homes, his grandson has reversed the process.
