The drain starts off in brick around 7ft tall. This then alternates between short stretches of RCP where repairs have been made, before opening up into a large egg shaped section.
Hidden on the riverbank of the Irwell the outfall looks like a portal into a time gone by.
This drain is in one of Manchester's surrounding northern towns and was a bit of a stooper, 3ft RCP being king here.
Lock Stock is a Victorian/Interwar period brick overflow system that has two large overflow chambers and a 9ft overflow culvert.
Located near one of Manchester's fringe towns are two large CSO tanks. This one is built from concrete and is one of the largest underground spaces I have seen.
This culvert is found in Radcliffe near Bury, it's about 260m long and outfalls into the Irwell.
