The Explore............
Visited with Telf, access was fairly easy, down and through a man hole, the hardest bit was finding it, but a stroll in the park!!!!!!!!!!!
The exit was a little strange.........or should I say a little tight!!!!!!!!
A Bit of History...........
It was built in the 1980's for the eventuality of a one in thirty year storm, the bunker system is around seven miles long of a concrete monster.
The bunker is a storm drain located in the Southern area of Warrington, taking overflow water from various rivers and carrying it underground to the outfall at the Manchester Ship Canal. It incorporates various inspection chambers, some three storeys' high, a huge junction chamber, and massive steps which create a loud whooshing noise down. Also there is an impressive swirl chamber towards the start of the drain with a large downfall pipe, to slow the energy of the incoming water and drop it to the drain below. There is also a sealed sewer pipe running next to the drain.
I hope you enjoyed the report
