Sir Joseph William Bazalgette ( 28 March 1819 – 15 March 1891 ) was one of the great Victorian Civil Engineers . As the chief Engineer of London 's Metropolitan Board Of Works , his major achievement was the creation of a Sewer Network For Central London that helped relieve the city from Cholera epidemics, while beginning the clean-up of the River Thames that had reached a nadir with "'' The Great Stink ''" of 1858 . BEGINNINGS He was born in Enfield , the son of a captain in the Royal Navy and grandson of a French immigrant, and began his career working on Railway projects articled to noted engineer Sir John MacNeill and gaining sufficient experience (some in Northern Ireland ) in land drainage and Reclamation works for him to set up his own London consulting practice in 1842 . By the time he married, in 1845 , Bazalgette was deeply involved in the expansion of the railway network - working so hard that he suffered a nervous breakdown two years later. While he was recovering, London's shortlived Metropolitan Commission Of Sewers ordered that all Cesspit s should be closed and that house drains should connect to sewers and empty into the Thames; a Cholera epidemic (1848-49) then killed 14,137 Londoners. Bazalgette was appointed assistant surveyor to the Commission in ''. Dr John Snow had earlier advanced the explanation that we now know to be correct: cholera was spread by contaminated water, but his view was not generally accepted. Championed by fellow engineer Isambard Kingdom Brunel , Bazalgette was then appointed chief engineer of the Commission's successor, the Metropolitan Board Of Works in 1856 (a post he retained until the MBW was abolished and replaced by the London County Council in 1889 ). In 1858 , the year of the Great Stink , Parliament passed an enabling act, in spite of the colossal expense of the project, and Bazalgette's proposals to revolutionise London's sewerage system began to be implemented. The expectation was that enclosed sewers would eliminate the stink ('miasma'), and thus reduce the incidence of Cholera . SEWER WORKS At the time, the Thames was little more than an open sewer, devoid of any fish or other wildlife, and an obvious hazard to Londoners' health. Bazalgette's solution (similar to a proposal made by painter John Martin 25 years earlier) was to construct 83 miles of Brick -built sewers to intercept sewage outflows, and 1100 miles of street Sewer s, to prevent raw sewage flowing through London's streets and into the river. The outflows were diverted downstream where they were dumped, untreated, into the Thames. Extensive Sewage Treatment facilities were later built. The scheme involved major Pumping Station s at Deptford ( 1864 ) and at Crossness ( 1865 ) on the Erith marshes, both on the south side of the Thames, and at Abbey Mills (in the River Lea valley, 1868 ) and on the Chelsea Embankment (close to Grosvenor Bridge ; 1875 ), north of the river. The system was opened by the Prince Of Wales in 1865 , although the whole project was not actually completed for another ten years. The effect of the sewers was to reduce cholera not only in places which no longer stank, but wherever water supplies ceased to be contaminated by sewage. The basic premise of this expensive project was wrong, as so often happens; but the end result was much better than expected, which is a rare occurrence. AWARDS Bazalgette was knighted in 1875, and elected President of the Institution Of Civil Engineers in 1888. MEMORIALS He lived for some years at 17 Hamilton Terrace, St John's Wood , north London, where there is now a Blue Plaque in his honour. He later moved to Morden , then in 1873 , with his wife, six sons and four daughters, to Arthur Road in Wimbledon , where he died in 1891, being buried in nearby St Mary's churchyard. A formal monument (see photo above) on the riverside of the Victoria Embankment in central London commemorates Bazalgette's genius. OTHER WORKS
