Water supply and sanitation in London

Water supply and sanitation in London is provided by private companies.

[2] Much of the water supply and sewerage system was constructed during the Victorian era (1837-1901), in light of repeated cholera outbreaks.

[3][4] Greater London is located within the Thames River Basin District.

Approximately 70% of all water supplied to London is taken from the Thames upstream of Teddington Weir.

[8] The London sewerage system is operated by Thames Water and serves almost all of London, except for a small area where Anglian Water provides sewerage services.
