People's Republic of South Yorkshire.
1. The History
The Redmires Reservoirs are a group of three reservoirs in Fulwood, Sheffield, South Yorkshire, England. They are fed from various small streams rising from the Hallam Moors by including Fairthorn Clough. The three reservoirs are named Upper, Middle and Lower and date back to 1836 They were created to provide clean drinking water via a water course down to Barker's Pool 5½ miles away following Sheffield’s devastating cholera epidemic in 1832.

The former The Water Treatment Works/Filter Station on Long Causeway has been long decommissioned when it closed around 1997. It was stripped of its machinery and apparatus in 2013. It is currently on the market with Reeds Rains at a guide price of £277,000. It are located beside the Lower reservoir and date back to 1950. They supplied water to the south-western outer environs of Sheffield via the Ringlow and Rudd Hill service reservoirs. The systems utilized seven horizontal pressure filters (installed at its inception in 1950) and a clear water tank which was installed 1983. Preliminary treatment of the water was carried out in the lower reservoir before it was filtered. Lime was added to separate the natural aluminium from the water, making it clump together so it could be filtered out.

Despite the works producing water below modern standards it was of a satisfactory colour and cleanliness, and despite high iron and aluminium levels, was still safe to drink. A new plant was constructed opposite the old works in the mid-80s and with used the Sirofloc Process. The water from this new plant was then piped to the old works to be filtered as a final process.

Back on to the main road and up the hill towards the top reservoir, on the left can be found the Redmires Reservoir Plughole. It was a later addition to the dam constructed sometime in the late 50s/early 60s.

2. The Explore
Was a beautiful day to check out Redmires Reservoir with a dusting of snow and bright sun-light. There were works on the road just outside and in view of the filtration works and also next to the plughole or “Wasoooo”. Hence only a brief peak inside the now stripped works and entry to the plughole from the outfall rather than climbing down it. All-in-all a very enjoyable hour or so here.

A few random outlying buildings near the filtration works:
