Report - Fleet CSO and Storm Relief, London Dec 16 / Feb 18

[Ojay]

BTW, the Fleet Storm Relief is the most boring tunnel in London, good to get done and out of the way.

Really I enjoyed the Fleet storm relief, I think the NESR must rate highly at the top of the boring list surely as that’s one long featureless brick until you reach the end, bar the interceptor

Yeah get on it Mintyjimbob!

We did the middle section late afternoon/ early evening Siologen and it wasn't too bad, well we stayed on our feet! Know what yer mean though, everyone putting washing machines on and flushing toilets. Gotta watch out for chucking out time as well. A variety of smells then! Yup done the storm relief now, certainly won't be going back. Nice long spiral stairs though upstream.

 

[tallginge]

Haha miles of nothing (apart from the dropshaft) that i avoided in the NESR.

Great stuff, I enjoyed that report and set of photos!
It was good to get that long middle section done in one afternoon.
I just need to get that upper section done if I can bear the stoop under the canal.

 

[tallginge]

Thanks mate, yeah and it was a long afternoon. Was well chuffed and surprised that you can walk its entire length with no dangerously deep, fast or long stoopy sections. I might mission it up them stairs near where we began one day and catch up with yer on the upstream bit

This report is amazing and what you guys do is awesome, thanks

Quality report
Awesome pics! Spot on. This drain is best for the various CSO’s and Bellmouth Junctions!

 

[Hmp-Caver]

Awesome photos, I have to say that place looks and sounds terrifying, I would hate to be down there and get washed away by a flap opening up or something...

Hi
This article is one of the fascinating and greatly informative piece I've read on this site. Don't get me wrong they are all fantastic, but this one is, well incredible. The research that has gone into this piece, the standard of the pictures and they way it's been described, I'm sorry but I am gobsmacked. Amazing, fantastic, incredible.
Many many thanks for sharing

I'd an afternoon free so decided to dust the wadorz aff and have a quick look down the Fleet to see how things are looking now that Tideway have connected the CSO to their dropshaft. Here's hoping that someone will do the rest of Tideways connection tunnels because there's plenty of online pics of big holes on the Thames foreshore, plenty of pics of the victorian brick pipes (thanks to us lot) and plenty of cute drawings with lovely annotation but there's nothing like seeing all the complicated and fiddly heavy civils work come together is there. Apparently this connection was particularly complicated to construct - or at least complete. The link describes the work carried out brilliantly

Excuse the poor quality pics. You get the idea.

This is underneath Blackfriars Bridge roughly in line with Bazelgette's Grade 1 listed Embankment Wall. The twin pipes are victorian brickwork and used to be where overflows entered the Thames. Regularly.

Below is the "100m long precast floating culvert" section looking upstream up the Thames towards the dropshaft vortex. Up steps to Tideway site.

And this is about all I saw. Tumbling bay, three overflow pipes high up on the left (imagine how much it'd have to rain to fill miles and miles of 7.2m diameter Tideway tunnel up!) and then at the back, behind two open penstocks, is a chamber with two closed ones. In front of and above the penstocks is an accessible viewing balcony. Behind the penstocks is the dropshaft. Behind the blank wall on the right is the Low Level No.1 connection tunnel to Tideway - I wasn't walking up the Low Level in daytime flows to check it out though

Lots of flow monitors patsy

Bye-bye Mordor for a little while. Nice seeing you and all your people, briefly To the hills again.....​

Good to see the work progressing to this stage.
By the end of next year, Old Father Thames should hopefully be looking and feeling in somewhat better health.

great snaps there @tallginge and long time no hear from, when you typed about the sensors think you were referring to me, lol. This infrastructure looks good indeed, is any of it visible topside along the sides of the thames? Happy new year, PM anytime fella 😎

I was indeed referring to you, yes I guess the overflow flaps to The Thames will be visible and plenty of lids etc. Quite a lot of land space will be reclaimed from the Thames. You'd notice a difference but you'll not see much infrastructure topside. Happy New Year 👍

Chuffing hell!! Thanks for that picture, seems quite a big project!! Will send you a PM.

Great stuff! Have they cleared the sludge out of the original outfall chamber then? Or any other changes ahead of connecting it up? I guess it won't be subject to backfilling from high tide anymore
