This is the drain that got me into draining. I found a dark filled entrance, heard the water and smelt the culvert smell. After heading back a bit more equipped I went in and got my first taste of an underground river.

Gorton Falls was built by the Victorians in 1876 to keep the increasingly polluted waters of the Gore Brook out of Debdale reservoir. Four aqueducts carry the culvert across the water with the rest hidden within the banks.

Build around 1790 this tunnel was built underneath the Castlefield Basin to deal with the excess waters of the River Medlock not used to supply water to the Bridgewater Canal.

All Ova is the last culvert of the Sudden Brook before it flows into the River Roch, it's pretty long at 900m and mostly big CMP although not all of it is walkable.

This old culvert built mostly of brick and stone takes the Sudden Brook around 550m through Rochdale.

The River Medlock flows through Manchester City centre taking a meandering route through open air and the Spartacus and Budge culverts.
