Designed specifically to prevent any fuel spillage in the pit from
escaping and contaminating the surrounding area, the two piece
construction of the pit provides a large welded inner catchment
area with over 0.3 cubic metre capacity below the seal. The
design allows for a very large ground movement, 25 mm (1-inch)
vertically and 50 mm (2-inch) horizontally, without affecting valve
operation and preventing stress or damage to the riser pipe.
