Plans for a huge canal, connecting Northumberland and Cumbria with London, are being drawn up by an American company. The idea is to provide water supplies for the South of England.
The canal would begin by drawing water from the Kielder reservoir in Northumberland, and would then go west into Cumbria, using gravity to continue its flow further south to Leeds, Birmingham and onto London.
Aecom, the engineering company behind the London 2012 Olympic Park, says it could cost £14billion.
