Skully Relief Sewer and CSO, Stockport
This new CSO constructed under Mersey Square has only just been completed, so much so I had to jump the fenced off compound to grab a pic of the liddage that sits in front of the Plaza ^
Credits to FreshFingers for getting this done and for the invite on the follow up visits with Alley
(We also managed to drag Nickindroy in on on a recent re-visit)
'Getting in' was never going to be straight forward
..Oh wait
The outfall is a slippery RCP, which quickly gives way to a steep 4.5ft brick egg
(this is looking back down towards the river)
Eventually the steep incline levels out, the amount of times we nearly tumbled back down I lost count
The smell of fresh filled my nostrils as we headed up the overflow which stretches a fair distance
Eventually a small inspection chamber presents itself, ahead of the newly installed powered screen
You can see where the original brick egg has been truncated and merged into the newer chamber
A short crawl up a RCPP leads to the powered screening chamber as modelled by yours truly
It probably came as no surprise to Alley that the first thing I did was jump over into the p00p department
This pic was taken on a previous visit, and the shit scraper was covered in.. Well shit and lots of it!
On the return visit it looks like UU have been down to give it a polish
Beyond the machinery the sewer continues u/s via another RCPP (Re-inforced corrugated plastic pipe)
It was 1ft deep with stale
and having stirred it with my size 10's I decided to get a move on
In the distance another inspection chamber which allowed for a further back stretch before once again changing back to a stoopy 4.5ft brick egg
The upstream section was long and slippery, a couple of smaller side pipes entered along the way
Around 200ft of this..
We came to this..
A weir up into a smaller section of pipe heading upstream
It was fairly confined and very slippery with no easy way up so we decided to head back
Back in the CSO, you can see where the relief sewer exits via a small slot, here a Penstock can be raised/lowered when required
Sadly there is no easy way out of here with these beastly hatches guarding the place
It was good to finally see what was down there, massive thanks to Alley and FreshFingers for the outings
