I support the view of Peter Bell (NCE 27 July) that the idea of a water national grid should be nally knocked on the head.
Those who support the idea are obsessed with existence of the gas and electricity grids but completely ignore the physical properties of water, which are completely different.
If such a water grid were to be created, would it connect the precise areas of need and availability? And would the water ow in the right direction?
Use should be made of rivers to transfer water between catchments as has been done in East Anglia and in the Lune-Wyre scheme. On the south coast, average rainfall decreases from west to east.
Neighbouring water supply units should be adequately connected to allow transfer of water from the Hampshire and even the Avon Dorset catchments to Sussex and Kent.
Fred Needham Green propounded this idea 45 years ago when he was the Engineer to Brighton Water.
