Jack-In-The-Box, Manchester
Myself and nickindroy spent most of the evening trying to get a lid back down in the middle of the road that had "managed" to jam, wouldn't mind it didn't lead to anything useful!
About half an hour with a sledge hammer, planks of wood and various other useless props we managed to level it
I was ready for turning it in before I remembered another lid nearby which leads into another bit of the system I had on my age old list of things to follow up
Here a 3m side entry manhole shaft drops onto a landing
An 'L' shaped walkway sits above a 5x3m brick storm overflow (The original inlet is now bricked up, as the upstream sewer overflow has been diverted elsewhere..
A smaller combined sewer enters via a 1.5ft pipe, down a small tumbling bay before taking a U turn and exiting into another smaller chamber
Climbing down the ladder the other side of the walkway and you can grab a closer look as the sewer exits via a 2ft pipe
The downstream sewer is only small and despite previously lifting a number of lids revealed nothing of any sizeable interest
Back in the main chamber a rather smart looking brick pill overflow sits behind some iron beams; a typical primitive screening system seen in many older CSO's
During capacity this overflow will come into use to alleviate the smaller sewer, however the more sizeable u/s stuff has been upgraded now and is no longer served by this overflow
Thanks for looking
