Back at this drain again with my proper camera! If you saw my last post in this drain you will have noticed they were pretty substandard phone photos, so having time to get out today I decided to get this one done so I dont need to come back!

Decepticon
Decepticon is a storm relief drain/cso (combined sewer overflow), it runs for approximately 5+ miles (as jezzyboo has absolutely crushed this drain by getting to its practical end, cheers!) It has many different construction types and heights, and many chambers which are ridiculous in size. Its main purpose is to drain surface water and rain water, however a sewer runs directly opposite it in its last 1km and pops up every now and then in chambers to stink it up (the sewer holes did have covers on them however for some reason they have been taken off).

The outfall is very pretty with lots of growth and beaming sunlight (however that 4ft entrance isnt) The outfall had a very strong "fresh" smell to it, so I knew I was in for a treat! Getting to the outfall around the 7 foot fence was quite a challenge but didnt cause any major problem (seriously, the security to the outfall is shite, you basically just climb around the fence)

This is where it outfalls into the River Rother, scenic! Now, lets get in!

Hunched over as I started to walk in, the tunnel turns 40 degrees right, then another 40 degrees right. The sound of crashing water ahead was rather menacing to say the least, but I've been in enough of these echo filled places that I'm used to it!

The construction changes to where the box culvert is flipped 90 degrees! Very tall to walk in and made this sooo much easier.

:(
Looking back.

Then we enter the corridor section, apologies for the over exposer in this photo :(
943288


Construction changes once again, a small chamber and we get to peak at the sewer :p
943289


Ooo-eye! Lovely.

Onward! This is my favourite type of construction in the whole thing, not slippy at all and very roomy! This section is quite long, the sound of water is getting louder!

Size comparison:

Soon we entered this massive chamber, my favourite chamber!
943294


Same as last time, I climbed to the ledge to get a photo!
943295


Up the ladders to the second level, looking down at my tripod and the tunnel below!
943296


Onward again, we come to the sewery chamber! Didnt smell too nice in hereI tell ya!
943297


My foot marks on the scummy RCP floor...
943298


The RCP.
943299


In the chamber, we can see the sewer in its full might!
943300


And bleedin 'ell it were loud!
943303


943301


Still baffles me how deceptive the photo is, that drop was 2+ meters I promise ya, and that sewer was 3ft RCP.
943302


Looking down at the RCP from the sewer view legde!
943304


On my way back I decided to take more silhouette photos, let the montage commence!
943305


Approaching the first chamber again!
943306


Spacecraft corridor section!
943307


Love this photo, shows the drastic change in height!
943308


"Argh mi back"
943309


Until finally, daylight and fresh air, not "fresh" air...

Amazing explore altogether, enjoyed every bit of it! Thanks for looking ;)
