The Buildings

Looking back it's possible to see where the suction main rises to ground level where it joins the back of the Engine Chamber. This short section of pipe includes the Inbleed Valve, Inbleed Silencer, the Isolating Bulkhead (to disconnect the cell when Cell 3 or Cell 4 are being used) and an Atmospheric Flap Valve.

The trench is slowly flooding (we had to wade through oily water during our explorations of Cell 3) as indicated by the reflections in the base of the trench.
