And not for long if you do! The excess of rainfall over evaporation
in the UK varies between c. 25 cm and c. 1m (in inhabited areas).
There would need to be some way for those tanks to drain to a local
river.

Indeed.

I think the OP was intending for these tanks to drain direct to the
drainage system and that the question related to how much around the tank
could be expected to be drained in to them, as regards that I have no
idea as I have never gardened on clay but I suspect it such a wide spread
problem that there must be info out there on spacings, depths etc
