Thirlmere Aqueduct

The Thirlmere Aqueduct is a water pipeline that stretches over 95 miles from a reservoir in the Lake District to Manchester, moving water across the landscape through channels, tunnels, and pipes. The system crosses varied terrain including moorland, valleys, and hills in northern England.

Construction of this water system started in the 1880s to supply drinking water to the rapidly growing city of Manchester. Different sections were completed over several decades, with tunneling under mountains presenting significant engineering challenges.

The inauguration ceremony in 1894 gathered local officials and residents at Albert Square, where water flowed through a temporary fountain marking industrial progress.

You can observe different sections of this pipeline in the landscape, especially where it runs across open areas or visible dams and channels. The best time to explore is during dry weather when hiking over the hills, where you may cross parts of the system.

When building a tunnel under one of the mountains, workers dug from both ends and met almost exactly at the midpoint. This precision was remarkable given the surveying technology available at the time.
