This CSO serves a town to the East of Manchester, it takes sewer overflows to a big tank at the works or diverts into the local river.
This culvert takes a brook just over 300m and varies between brick horseshoe, CMP, stone arch and eventually splits to a stoop before the infall.
Found in Bolton this drain is about 400m long and sports a grill at both ends, the watercourse eventually joins the Croal.
This small drain outfalls onto the River Croal in Bolton town centre, it's just over 300m long and constructed mostly of stoopy RCP around 4ft.
I had been pondering over one such drain with along with Nckt and TheVicar for a while now. We knew this drain had an unusual setup so were eager to finally explore it.
This CSO system is Heywood's largest overflow into the River Roch consisting of 3 separate sewer overflow connections which meet before dropping into a culvert to the river.
This CSO into a small brook provides a screened overflow for the upper part of Heywood's sewers.
