A short (500m or so) concrete culvert that carries a brook beneath roads and houses in Exeter. I do apologise for my photographs being turds of the unpolishable variety, but I've yet to venture much further than the point-and-shoot world of photon00bishness. Not too hot on features, but it's a great place to start out with draining as it is easy to access, has fresh air and clean water.
Anyway, on with the report:
The infall.

Looking downstream from near the infall. The vertical steel tubes do not reach the roof and are too thin to be supports. I wonder what they are for...

A short sidepipe leads to a small CSO chamber.

Loads of drain spiders as always...

A drain slug. The water from this pipe started to flow as I took this shot. I thought "Crap it's raining! GET OUT." Luckily it was a false alarm and I returned later that day after checking the local forecast.

The tunnel splits into two parallel rectangular concrete passages about two thirds of the way down.

A relatively large sidepipe joins at the split point, though grip gloves and a skateboard are in order to navigate this one without crawling. Daylight is visible from the two small openings above the pipe.

Further down another sidepipe leads to (guessing by the smell) another CSO. You can just about see the pipe split into two smaller ones in this shot.

The two rectangular tunnels are connected by these openings at regular intervals.

Many small sidepipes join the culvert toward the downstream end.

The end is nigh!

Cobwebs and mineral straws. I'm guessing the minerals are leaching from the concrete as there's barely half a foot of soil above it.

The height of the tunnels is reduced a short distance from the outfall and I had to stoop a little here.

Looking back upstream from a bridge a short distance down from the outfall.

Looking downstream from the same position. Climb the wall to get out.

Finally, further upstream on the same brook is a much older brick culvert that carries the brook beneath a small railway station and beyond. It is shorter than the downstream culvert, but I'll save this for another day.
