Joseph Bazalgette; construction of the sewers

The video discusses the cholera outbreak in London and the subsequent construction of an extensive sewer system to combat it. Over 16 years, 82 miles of main sewers and 1,100 miles of street sewers were built, along with pumping stations and treatment works. The design included doubling the tunnel size to accommodate future needs and constructing embankments along the River Thames to house sewer pipes. The innovative design featured brick tunnels shaped like upside-down eggs to support the city's weight, hailed as a modern engineering marvel.
