Stamford Brook

Stamford Brook was a tributary of the Tideway stretch of the River Thames in west London supplied by three headwaters.

Surface water and foul water drains beside and under short stretches of Piccadilly and District lines[n 1] followed by the rear of numbers up to 438 Chiswick High Road, then turn ENE follow the lowest depression of that watercourse, cutting across Chiswick Common, crossing the District Line at Turnham Green tube station to reach the formerly seasonally waterlogged, low-lying area of Stamford Brook Common.

[n 2] Fresh water features such as the fishponds by the London Transport Museum Depot on the current location of Acton Town Underground station have been lost due to use of the depression for separate drainage systems.

[n 4] This course, now overtaken by segregation of surface water drainage and sanitary sewers afterwards ran the line of Paddenswick Road where it was joined by a flow emerging from Ravenscourt Park.

[10] The eastern mouth, Parr's Ditch was a more complicated, field-watering affair, an alternative brook as the main area inconveniently for agriculture overflowed at times and for irrigation of Hammersmith, that continued due east through Hammersmith into a natural trough, now the long park known as Brook Green.

[5] Close to the River Thames, the lower reaches of the above routes used for sanitary sewers are intercepted by Sir Joseph Bazalgette's Northern Low Level Sewer which reaches the Northern Outfall Sewer in Stratford, however directly south of the original mouth are overflow outfalls in Furnival Gardens and of the western mouth on Chiswick Eyot which regularly are in use during rainy days, leading to a major project underway, the Thames Tideway Scheme,[14][15] a strong motivation for which is the desire to comply with the EU's Urban Waste Water Treatment Directive.
