5.5.1.2 Excavation: Depth
The depth that the Tricel Novo must be installed is determined by the outlet pipe from the source
of the wastewater.
Please refer to section 5.9 ‘Risers’ to determine the maximum invert for the Tricel Novo. Allowances
for maximum inverts must be made when the connecting sewer system is being designed by a qualified
individual. The Tricel Novo is not suitable where a deeper installation is required.
Outlined below, are the minimum distances (mm) that the excavation dimensions must exceed the
tank dimensions for both concrete and gravel installations. Please refer to section 3.1
, ‘Dimensions’
to view all tank dimensions.
Note: Ground instability, e.g. running sand may necessitate over-excavation and stabilization with
hard core or blinding concrete.
