our first drain we ever explored.
We explored Croydon or "wandle" drains in two parts. The first being the easier walk in relief in the southern districts and the second being the harder entry heavy as hell manhole in the west.
The first part was a bit dull. A long concrete box relief that kept going on for around about a mile without any real features appart from the one at the end, where the water flow is diverted underneath a wall and on to something else unknown to us. We have yet to find anyway around this.
The second part was a bit more interesting. After opening our manhole we climbed down the old ladder and came out in a large chamber with two large pipes running northwards and a relief similar to the other explored running down south ending in another diverting wall.
We took a few photos and then walked up the pipes after 20 meters it opened up into another chamber with a pipe running eastwards and a small set of stairs running to the north. At the top of the stairs the roof came down to less then a meter making it a pain to walk so we called it a day and headed back to the surface.
It was the start of something new.
