Essentially the Clapham Storm Relief and a CSO which serves the Southern High Level No.1/Putney & Clapham extension & Balham Sewers
Originally I had set out with Adders to look at something else, but we weren't suitably equipped and the next lid was a fair walk and time was against us
We opted for a quick look in here instead as we were nearby
One thing I've noticed, as soon as you mention drains to anyone, even fellow explorers it's an instant gurn
Once facial features usually return to normal most people just walk away leaving one muttering to ones self
Whatever opinion you have about them, you can't deny the epic over-engineering by the Board of Works that exists in London
There is something about Victorian brickwork that is hard to ignore, this place is no exception and simply stunning!
You would be forgiven that dropping into this rather small (8ft x 4ft) egg overflow and traipsing about would reveal anything decent..
WRONG... slip & slide upstream and throw down some lumens and you might have a different opinion of sewers :
Of course my pics don't really do the place justice and there are much better examples kicking around, none-the-less it was good to finally drop into this one
Here the 8ft egg quickly turns to around 13ft ahead of the overflow
Here the Southern High Level No.1 enters on the far left, Putney & Clapham extension on the right, with the Balham sewer in the foreground
Here the Southern High Level exits via a smaller diameter arch as it eventually heads on down to the Southern Outfall Works, Crossness
Looking a bit closer upstream you can see one of the original carts/bogey's used during the original construction, since discarded between the converging sewers
Overflow - Southern High Level
Putney & Clapham extension
A single sided weir/oak dam boards serve as an overflow, passing underneath a now defunct penstock before droppping into a pit of soup beyond which is the Clapham Relief
Adders mentioned something about a beer garden..
This wasn't it, but a couple of cold ones and a spot of World Cup at the nearby boozer shortly afterwards was a welcome sight
Mind the Fresh
Thanks for looking
