History of Longdendale
The Longdendale reservoirs — Woodhead, Torside, Rhodeswood, Valehouse and Bottoms — form the oldest large-scale municipal water supply system in the world, built between 1848 and 1877. Longdendale has been an important trans-Pennine route since Roman times. The Woodhead Tunnel, built in 1845, was one of the most ambitious railway engineering projects of its age when constructed.
Understanding the history and character of Longdendale helps explain why the housing stock here may be well suited for home insulation installations. Victorian and Edwardian properties often have solid or cavity walls typical of the era, where insulation improvements can be particularly effective in the Ashton-under-Lyne climate.
