If anyone is interested in the water supply of Middleton-by-Wirksworth, I can supply a few facts.
One of the main supplies to Middleton used to be the old sough on the hillside above Hopton Wood (associated with South Thumper Sitch Vein – see Flindall’s article in PDMHS bull Vol 5 Part 3 p143). By 1930, this was failing because of the approach of the quarry face. To replace it, Mr. Key offered the use of Dunsley Spring on the south flank of Bonsall Lees. By an old agreement, Middleton Council was allowed to take 15,000 gallons per day from Dunsley Spring. However, in 1935, proposals to take this water were blocked by the owners of Hollins Mills in Bonsall Hollow who wanted £500 compensation for any loss of water to their mill. Instead, it was suggested to supply Middleton from the Wigwell borehole near Wirksworth. A public enquiry was to be held.
