This little culvert outfalls to the Croal in Bolton, it's a bit of a mashup of stone, brick and Ironwork. I went for a look with Snake Oil and ViralEye.
A 1.6m sewer comes into this concrete CSO chamber at a steep angle, the flow thunders down and kicks off a crappy mist that settles on every surface.
Found in South Manchester this screening chamber serves a 6ft sewer. A couple of curved grills with rotating combs scrape solids into a return channel as the overflow proceeds down through a pipe to the Mersey.
Hyde Falls takes the Wilson brook under a canal and motorway and features a large chamber with two waterfalls.
This overflow sits on a large sewer in Warrington, any overflow passes through a large vertical mechanically scraped grill.
These small culverts take the River Beal under the M62 near Milnrow. Both stretches are featureless double concrete box around 5 1/2ft tall, a couple of waterfalls in the open being the most interesting bits.
Shatterproof is essentially the overflow for the In My Sights tank. I met up with troubleuk to have a look at the downstream section.
