So, as a rule, the nice people at Ordinance Survey are a pretty reliable bunch of chaps (and chappesses)

So when I noticed this:

There were only a couple possible explanations, either they had let Kevin the YTS trainee* do the blue lines - and he forgot to join them - or there was something that needed looking at.


(*Younger readers should ask their mum/dad what YTS was :thumb)

So, a quick drive to Exeter, and there it was, The North Brook Culvert.

Running for about 800m it forms part of Exeter's strategic flood planning.

So, a few pics I think:

The upstream in-fall.

Complete with otter footprints, preserved in the concrete...

The ridge in the center - which you will see continues for some distance, would seem to be a concreted over sewer pipe - as it has vent pipes at regular intervals - although it doesn't seem to be connected to anything.

Running parallel to the culvert, and connected at a few points would seem to be a CSO - it certainly sounded in full flow - but as the rain was coming down big time I decided to leave those for another day

This dual channel section runs for probably 5 or 600m....

As do those vent tubes - they stop just short of the roof...

At the end of the dual channel section the flow is joined by another 4 foot concrete pipe, with a moderate flow of water - presumably this also meets the CSO - I followed it about 50m - but got pissed off with stooping.

At this point the culvert divides into a pair of parallel box section channels, which are joined at regular points by openings..

Starting at a reasonable, non-stoopy, height - these get lower, and lower, towards the end - with barely 4 feet of headroom as you approach the end.

And, of course, you can always tell that the end is in sight - when your camera starts to steam up!!

And out - this channel was not even full side to side when I entered, filling up nicely now - thanks to the rain.

And that's it - a nice little wander for a Sunday - beats washing the car, going to Ikea, or whatever others do on a weekend :)

Thanks for looking :)​
