Water supply and sanitation in London

Water supply and sanitation in London is provided by 32 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, 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 Lea. 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 (about 70% of population)[6], Affinity Water (14%)[7], Essex and Suffolk Water and SES Water.[8]

Sewerage

All of Greater London is within the Thames River Basin District.[9] 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.
