•
Establish the proposed/final forecourt ground level (A); mark this point on the site column.
•
Install the sump box enclosure into the correct position below the proposed ground level
as shown in Figure 3.
• Ensure the pipe delivery ducts protrude 50mm above ground level (B) and 20mm (C)
proud of column for a 250 x 250mm column. For a 250 x 320mm column, the distance
between the end of the protruding delivery ducts and the external side of the column
should be 50mm (D).
• Check the end face of the enclosure is 300mm (E) out from the column.
Note:
Ensure the underside of the enclosure is firmly packed to prevent the enclosure
from sinking or moving.
•
Pack filling material around the sump enclosure approximately up to a point just under
the bulkhead fittings; this is to ensure the enclosure does not move while further work is
being conducted.
