Joseph William Bazalgette red and black plaque in London
The Crossness Engines The restored 1865 Prince Consort Engine was a key part of Joseph Bazalgette's sewage system and is one of four James Watt Rotative Beam Engines still in its original setting. Representing the change from cast iron to steel and the more effective use of steam, it played a key part in freeing London from Cholera and Typhoid.
Sir Joseph William Bazalgette, CB (28 March 1819 – 15 March 1891) was a 19th-century English civil engineer. As chief engineer of London's Metropolitan Board of Works his major achievement was the creation (in response to the "Great Stink" of 1858) of a sewer network for central London which was instrumental in relieving the city from cholera epidemics, while beginning the cleansing of the River Thames.
