This isn't on the Wirral, but follows on from the rest of this post, it was part of the GPSS pipeline system which was what followed Pluto (or was part of it). This was on the route over the Pennines (actually through Derbyshire) from Stanlow to Paull (Hull). This is at Poynton, the route also goes through Whaley Bridge (it burst there !). The Links below are interesting.
Discovered whilst looking around at Poynton's coal mining heritage. We only know (local quote), that "its a pumping station". I guessed it was part of GPSS, but that is actually further north, from posts where it goes beneath the canal, also confirmed by Alan Turnbull, from Secret Places. We were actually correct, it was a pumping station on the GPSS pipeline system, but the pipeline was re-routed after the war.
The GPSS system connected the Shell refinery at Stanlow, via the storage farm at Backford, via Rawcliff Bridge to the refinery at Paull (HUll) to supply airfields in the east, and down to the south coast to supply Pluto at D-Day to Europe.

The site has been partially re-used as the council tip (recycling centre).
There are 2 main buildings, one offices, the other "plant", a small circular brick wall (sewerage bed ?), and some blast walled undergound steps, blocked off.
