Visited with buddah and a couple of mates.
We did this one a few days ago, three out of the four of us had never done a drain before, me and buddah both being n00bs, so we thought we'd try one pretty laid back and straight forward. Off we set to Warrington.
After a leisurely stroll trying to avoid dog walkers whilst loitering around man holes, we managed to swiftly lift a lid and drop in. We headed upstream and towards the vortex / plug type thing.
Were were expecting a circular concrete tunnel that goes on forever, and our expectations were met. :-) Starting off approx. 2.1 M diameter the tunnel reduced to about 1.5 M. We had a good mooch around two separate tunnels, one getting continually decreasing in size, so we gave up on that one!
I couldnt believe the depth of some of the inspection chambers, 3 storeys high in places! Eventually finding the vortex, we concluded there and headed back, getting a few snaps on the way.
A good trip out, and a good first experience in a storm drain. Will definately do another!
