The Great Stink was an event in Central London during July and August 1858 in which the hot weather exacerbated the smell of untreated human waste and industrial effluent that was present on the banks of the River Thames. The problem had been mounting for some years, with an ageing and inadequate sewer system that emptied directly into the Thames. The miasma from the effluent was thought to transmit contagious diseases, and three outbreaks of cholera before the Great Stink were blamed on the ongoing problems with the river.
The smell, and fears of its possible effects, prompted action by the national and local administrators who had been considering possible solutions to the problem. The authorities accepted a proposal from the civil engineer Joseph Bazalgette to move the effluent eastwards along a series of interconnecting sewers that sloped towards outfalls beyond the metropolitan area. Work on high-, mid- and low-level systems for the new Northern and Southern Outfall Sewers started at the beginning of 1859 and lasted until 1875. To aid the drainage, pumping stations were built to lift the sewage from lower levels into higher pipes. Two of the more ornate stations, Abbey Mills in Stratford and Crossness on the Erith Marshes, with architectural designs by the consultant engineer, Charles Driver, are listed for protection by English Heritage. Bazalgette's plan introduced the three embankments to London in which the sewers ran: the Victoria, Chelsea and Albert Embankments.
Bazalgette's work ensured that sewage was no longer dumped onto the shores of the Thames and brought an end to the cholera outbreaks; his actions are thought to have saved more lives than the efforts of any other Victorian official. His sewer system operates into the 21st century, servicing a city that has grown to a population of over nine million. The historian Peter Ackroyd argues that Bazalgette should be considered a hero of London.

Brick sewers had been built in London from the 17th century when sections of the Fleet and Walbrook rivers were covered for that purpose.[a] In the century preceding 1856, over a hundred sewers were constructed in London, and at that date the city had around 200,000 cesspits and 360 sewers. Some cesspits leaked methane and other gases, which often caught fire and exploded, while many of the sewers were in a poor state of repair.[2] During the early 19th century improvements had been undertaken in the supply of water to Londoners, and by 1858 many of the city's medieval wooden water pipes were being replaced with iron ones. This, combined with the introduction of flushing toilets and the rising of the city's population from just under one million to three million,[b] led to more water being flushed into the sewers, along with the associated effluent. The outfalls from factories, slaughterhouses and other industrial activities put further strain on the already failing system. Much of this outflow either overflowed, or discharged directly, into the Thames.[4][5]
