Letters: Path of least resistance

If Aecom wants to get water from Scotland to south east England (NCE 18 October) it would do better to avoid the Pennines and stick to eastern England which is a lot flatter.

If they could get to the Oxford Canal near Fenny Compton, 10km north of Banbury, it is downhill all the way to the Thames at Oxford. Simpler still to pump water from the Severn above Gloucester into the headwaters of the Thames.

It is high time the problem was looked at nationally and money invested in solutions.

  • Yes, at this point we use as our default, the principal line within the 1942 Pownall Grand Contour Route. This runs down the Eastern side of the Pennines. It would be a series of flat runs, relying on the hydraulic gradient for a slow flow, but separated by a few locks, strategically placed to control levels and help negotiate crossings.

    If we can find a suitable slightly lower route, this will take the line a bit closer to a number of power stations and steelworks, which will be handier for taking the waste heat for district heating purposes. The canal could be used for transporting biomass from the North to some power stations.

    Its worth thinking of it as a linear reservoir, and it could be used to supply farm reservoirs and to top up existing streams, and canals like the Oxford canal. We are trying to avoid pumping as much as possible.
