If £2bn is to be made available for a useful public health project (like the proposed Thames Tideway tunnel), I wonder if I am alone in preferring to spend such a sum on a scheme to transfer water from the wet north west to the increasingly needy south east of the country, rather than on a dodgy and difficult project to move some diluted sewage down river in order to save a few fish once every few years.
It seems incredible in these days of trans-continental pipelines, that in these small islands a regular surplus of water in about half of its area cannot be used to ensure an adequate supply to the desperately dry part.
