BORE HOLES - DEANHEAD BORE-HOLE
In 1945, a shaft and bore-hole were constructed at Deanhead,
overlooking the Reservoir and alongside the New Hey Road,
S.W. of Nont Sarah’s Hotel, and near the Slaithwaite-Scammonden
Boundary, at an elevation of 1,265.4 feet O.D.
This bore-hole descends to near the base of the Upper Kinderscout
Grits, which are here 309 feet from the surface and about
300 feet in thickness. The shaft is brick lined, and has
an internal diameter of 9 feet, and extends to a depth of
390 feet, from which an adit, 6 feet by 4 feet, is driven
for a length of 120 feet.
From the bottom of the shaft, a bore-hole 18 inches in
diameter, is carried down a distance of 302 feet, giving
a total depth from the surface to the bottom of the bore-hole
of 662 feet.
A continuous pumping test was carried out between the 1st
to the 10th of April, 1937. The water level at the commencement
was 136 feet down, and at the completion 290 feet. The total
quantity pumped was 1,576,510 gallons, giving a yield of
1,263 gallons per hour over the whole period. A permanent
pumping station has not been erected at this borehole.
