This is a very interesting topic SteveHB , hopefully members will add to it and it may take off like the drain spotting one did. I do remember a few wells and troughs but have no pictures of them so can I add, please, a couple from Picture Sheffield of two on Wharncliffe Craggs, a place on which I spent many an happy hour before I left Sheffield. The Dragon's Well and Wharncliffe Rock Water Troughs .
