That is quite fascinating, Jon, especially those in the NW of

places of late (S and E) are above 50% and E Anglia is at 73%.

But where do the various water companies actually obtain their
supplies from. I suspect that the SE uses far more bore hole water
than reservoirs. After all it's a bit difficult to build a reservoir
when you haven't any hills to use as the sides...

Something has been bothering me for a while -

I regularly run through what is know as the 'Water Catchment Area' on the
north edge of the North Downs. There is about 4 reservoirs in a particular
valley with lots of man made half-pipes dug into the hill sides that run
into them. It amazes me that during the summer, when hardly any rain fell
at all here (Aug 17mm, Sept 4mm) that water was running, not just trickling,
down nearly every half-pipe all the time. Even when it didn't rain for
something like 3 weeks at the peak of the summer heat, there was always
water rushing down into the reservoirs. I'm not aware of any springs in the
area, so where does all the water come from?
