London Sewers

The Great Intercepts Main Drainage System of London

North of the Thames are the High Level, the Middle Level, the Low Level, and the Western District Sewers, together with an Outfall  at Barking Creek.  The High Level drains Hampstead, Highgate, Kentish Town, Highbury, Stoke Newington, Hackney, and passes under Victoria Park to Old Ford; its length is about 9 miles.  The Middle Level runs by way of Kensal Green, Kensington Park, Notting Hill, Bayswater, Oxford Street, and so under a number of minor streets, to Old Ford, being about 12 miles long.  The Low Level commences near Pimlico, and passes along under the Thames embankment to Blackfriars, whence it is to go through the City and Whitechapel to West Ham.  The Western District Sewers drain Acton, Hammersmith, Fulham, Chelsea, &c., on a plan different from that of the main drainage in other localities.  The Outfall, an immense work 6 miles long, continues the Upper and Middle Level Sewers from Old Ford to West Ham, and all the three sewers thence to Barking Creek, where stupendous arrangements are made for conducting the flow of the sewage into the Thames.  The drainage south of the Thames comprises a High Level Sewer, a Low Level Sewer, and an Outflow.  The High Level drains Clapham, Brixton, Streatham, Dulwich, Camberwell, &c.; the Low Level keeps nearer the Thames, by Wandsworth, Battersea, Vauxhall, Lambeth, Southwark, Bermondsey, and Rotherhithe, to Deptford; while the Outfall continues both these lines of sewers through Deptford, Greenwich, Woolwich, and across Plumstead Marshes to Crossness Point, where the works are situated for conveying the sewage into the river.
