Water supply and sanitation in London
Water supply and sanitation in London is provided by private companies.[1] The regional water strategy for London is produced by the Greater London Authority.[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.[5]
Water supply
London has well developed water supply infrastructure. Most drinking water consumed in London comes from the River Thames and the River Lee. Approximately 70% of all water supplied to London is taken from the Thames upstream of Teddington Weir.[6]
Greater London is currently supplied by four companies: Thames Water (76% of population), Affinity Water (14%), Essex and Suffolk Water (7%) and SES Water (4%).[7]
Sewerage
All of Greater London is within the Thames River Basin District.[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.
