Pipe Work

After being stuck at Carisbrooke water pumping station all day and the sky being as flat as flat, I thought I would have a go at a bit of industrial pipe work.
This is the main shut off valve for the water coming from three bore holes, two about 60m down and the other about 100m, the water from these holes feed about a third of the Island, pumping up to 20+ mega litre a day (20,000,000) and each bore hole is an independent source.
