BOREHOLE water may be used to cool sections of the London Underground as part of the solution to overheating on the network.
Tests into the viability of the idea could be made as early as mid-2006, most likely at Victoria Station.

Using borehole water is just one of the solutions to be investigated by consultants Parsons Brinckerhoff in Phase 1 of London Underground's Tunnel Cooling Project. Other ideas are likely to include under platform exhaust systems and other techniques which Parsons Brinckerhoff has successfully applied to projects in the USA and the Far East.
With around 35,000,000 litres of water being pumped from the tube network every day, Victoria Station is seen as the most likely borehole test site, having been built above the underground River Fleet.
The initial phase is expected to last until March 2006, during which time Parsons Brinckerhoff will work alongside m&e contractors EMCOR.
