More recently multi stage centrifugal pumps were used and 5000 gallons per minute wasn't unusual (Whittle). (PS. My family think I've lost my mind too, there aren't too many left who have a knowledge and experience of this almost forgotten industrial history as most of it is left buried hundreds of feet under our feet or the sea!)

Here's a Anderson RH22 'Dosco'* or road heading machine, on the roadside somewhere in Scotland. (*Dosco was actually a competitor, but the name stuck for this type of machine)
There must be a load of these type machines scattered across the North East, but at depth! I'm sure they had two giant machines driving from Ellington to Amble that were still underground, abandoned years before, when the place finally closed.
Rather sad for me to look at this. That's what I was. A Dosco electrician. Worked on the modern versions. Tear in my eye. Never mind.
