I only found out about this place a few months back, its in Davyhulme Manchester on the ship canal. The place was used for pumping slurry into barges to be taken off down the canal. There are four pumps which have huge moveable arms which used to raise or low over the barges. The place is within the davyhulme millenium nature reserve and has good security, access would be possible, but water scares me so I didn't venture around the gates and fences.
