Joseph Bazalgette
Louis Bazalgette arrived in London from Ispagnac, France, as an economic migrant. He became a tailor and financier who served the Prince of Wales. His son Joseph William Bazalgette was born at Hill Lodge on the 28th of March 1819. The family moved to Hamilton Terrace in 1827 when Joseph was eight years old. He spent his early career articled to Sir John Macneill. This apprenticeship involved railway projects across China and Ireland. By 1842 he established his own consulting practice in London. The work required immense effort that eventually took a toll on his health.
London faced a cholera epidemic in 1849 that killed 14,137 people. Another outbreak struck in 1853 claiming 10,738 lives. Medical opinion blamed foul air known as miasma for these deaths. Physician John Snow had proposed water contamination but his view lacked acceptance. Parliament passed an Enabling Act in 1858 during the Great Stink crisis. The Metropolitan Board of Works approved Bazalgette's revolutionary sewerage system proposals. The project carried colossal expense yet received parliamentary approval despite opposition. Enclosed sewers were expected to eliminate the miasma thought to cause disease.
Construction began in 1859 on a network of enclosed underground brick main sewers. Portland cement ensured tunnels remained in good order over 150 years later. Major pumping stations appeared at Deptford in 1864 and Crossness in 1865. Abbey Mills station opened in 1868 within the River Lea valley. Chelsea Embankment work started near Grosvenor Bridge in 1875. Outflows diverted downstream into balancing tanks at Beckton and Crossness. Untreated sewage dumped into the Thames at high tide until 1900. Biological treatment first undertaken by William Dibdin in 1885 based on Edward Frankland's proposal.
The basic premise that miasma spread cholera infection proved incorrect. New sewer systems removed the causal bacterium from water supplies instead. This unintended consequence eliminated cholera in areas served by the sewers. Typhus and typhoid epidemics also decreased significantly across London. Bazalgette checked every connection to the system personally himself. Records contain thousands of linen plans with handwritten comments in Indian ink. Notes read Approved JWB or I do not like 6 used here and 9 should be used. His capacity for hard work drove the project forward despite overwhelming challenges.
Albert Embankment opened in 1869 followed by Victoria Embankment in 1870. Chelsea Embankment construction finished in 1874 along the river banks. Maidstone Bridge appeared in 1879 while Albert Bridge modifications occurred in 1884. Putney Bridge opened in 1886 and Hammersmith Bridge in 1887 as his second design. The Woolwich Free Ferry began operations in 1889. Battersea Bridge completed in 1890 marked another major crossing point. Shaftesbury Avenue development started in 1886 alongside Charing Cross Road improvements. Early plans for Blackwall Tunnel emerged in 1897 before his death.
Queen Victoria knighted Joseph William Bazalgette in 1875. He served as President of the Institution of Civil Engineers starting in 1883. A Greater London Council blue plaque commemorates him at 17 Hamilton Terrace. A formal monument stands on the Victoria Embankment by the River Thames. City of London Corporation named a new public space Bazalgette Embankment in July 2020. Dulwich College offers scholarships bearing his name for design technology or mathematics. His family included eleven children born between 1846 and 1861. He died on the 15th of March 1891 and was buried at St Mary's Church in Wimbledon.
