Rivers of Heathrow...not far from RWY23 :)
Unless they've been renamed the Twin Rivers, now forming the Southwest boundary of Heathrow,(both artificial and their courses moved at least twice ) are the Longford River and the Duke of Northumberland's River. They are both drawn from the River Colne. The Longford River runs on under Hanworth Air Park , past Bushy Park to Hampton Court (its purpose) where it joins the Thames. The Duke of Northumberlands River runs into the Crane near Hounslow then divides off again in Twickenham for Syon Park(its purpose) then into the Thames.
The lower stretch of the River Crane was recently sacrificed by Thames Water engineers when a 2 metre valve on a Sewer from Heathrow jammed shut (31 Oct 2011) and they were unable to remove by road tanker sufficient of the backed-up effluent.The lower 7 miles of the Crane was seriously polluted killing approx 3,000 fish.
Wikipedias available for all rivers mentioned.
