History
“The Redmires Reservoirs are a group of three reservoirs in Fulwood, Sheffield, South Yorkshire, England. They are fed from the Hallam Moors by various small streams including Fairthorn Clough. The three reservoirs are named Upper, Middle and Lower and were built between 1833 and 1854 to provide clean drinking water via an open water course which led to the Hadfield Dam situated in Crookes, following the devastating Sheffield cholera epidemic of 1832. The dams were built as part of the Sheffield Water Works continuing expansion to meet the ever growing population of Sheffield.”
