Beckton Sewage Treatment Works, formerly known as Barking Sewage Works, is a large sewage treatment plant in Beckton in the east London Borough of Newham, operated by Thames Water.
Since construction first began in 1864, the plant has been extended numerous times and now covers over 100 hectares (250 acres) - the largest sewage treatment works in Europe [disputed, Seine Aval in Paris also claims to be biggest].[1] It treats waste water arriving from the Northern Outfall Sewer and the Lee Tunnel, serving a large portion of London north of the River Thames.
The treated effluent from the plant is discharged into the Thames at the south-east corner of the site, adjacent to Barking Creek.
