As I was in Stoke anyway I decided it would be rude not to pop down a drain
Down Below was I believe discovered by LittleMike but if I'm wrong I'm sure someone will correct me.
The outfall is a 5 foot box affair which leads to two RCP which then join back up for a bit more box then it splits again into an 8 foot RCP and a much smaller RCP
I followed the larger pipe and the smell of fresh, after 15 - 20 minutes I arrived at the poop processor where I watched Stoke fresh flow by for a few minutes before heading out.
On with the pics
