Water from the borehole at Station Road Sandiacre was pumped to this service reservoir from where it gravitated to feed Sandiacre and Stapleford. I have in my mind a 7" Cast Iron water mains that either supplied the reservoir and or was the outlet main size. (from failing memory - John Simpson 2018)
This Service Reservoir has now been demolished and the land used for housing. A new reservoir was constructed on nearby higher land at Lady Cross.
