10.3.2 Excavation depth:
The excavation depth is determined by the inlet and outlet pipe, invert levels relative to the bottom of
the tank, and allowing for the minimum base thickness shown. Dimension details of the tank are shown
on the relevant drawing, supplied with the plant. Ground instability at formation level e.g. running sand
may necessitate over-excavation and stabilisation with hard core or blinding concrete.
NOTE: Check that the depth to the base slab is within the Service Specification requirements for the
tank.
