Double Drop, Bolton

St00py shit...

Whilst working in the area recently I decided to take advantage of the good weather and go check some long forgotten side pipes out.

All the good stuff in Bolton seems to be stoopy as hell, and it wasn't long inside that I realised this place looked a tad familiar.

He isn't called ConcreteJungle for nothing and it appeared to be another one of his previous st00pfests..

A grille covers barely a 5ft RCP, 

(Which you can smell long before you can see it)

Although primarily a small watercourse and surface run off for the nearby carriageway, it also acts as an overflow from the pumping station which sits above it.

You can actually hear the machinery chelping away from behind a small side pipe and a brick shaft beyond.

Sadly the smell of fresh soon disappears and it's back to good old H2o for around 320m before you arrive at some feeder pipes in a small brick chamber.

'Getting in' is a bit of a faff but once inside like I say it's about 4½ ft RCP all the way

The first real feature is this 3x2m penstock chamber around 50m up

Having later lifted a lid above ground I could see it serves a similar sized sewer (4½ft RCP) which appeared to be rather fast flowing so I decided against going down alone.

Pressing on another 20m or so I could here what sounded like a small weir getting closer

Sure enough, the next feature is a 5m brick drop shaft which funnels the watercourse down behind the brick wall.

Once > up > across > down, it's more backbreaking RCP once again..

Infact 80m nearly until you can stretch out in this small brick chamber before it takes a left turn heading upstream.

After around 20m I could hear what sounded like another weir, 

sure enough another brick drop shaft (this time a bit smaller)

..up top, 

a funnel which carries the watercourse down behind the brick wall

Once again it's back to st00py concrete, thankfully it was only a short distance before one could have another back stretch.

Here also couple of side pipes trickled into the small brick chamber.

The last stretch of the drain, which was silted up with debris and reduced the entire lot to around 4ft, this made for some hard trundling for a good 130m.

Finally a small brick chamber which marks the end for anyone over 2ft
