4.2.10 Backfill
Compaction of the backfill must be thoroughly done to make sure that the surrounding
material provides support to the structure of the unit.
NOTICE:
Do not allow soil or gravel to get inside the unit.
Counteractive loads are achieved by dead load of the concrete footing and vertical earth
pressure on the concrete footing.
1. Check that the following requirements are fulfilled:
– The unit must be level after backfilling.
– Backfilling must be correctly made around inlet pipes, outlet pipes, and the unit
bottom.
– The pipe work and the electrical connections must be protected and supported during
backfilling so that no load is applied to them by the compaction operation.
– The backfill must not contain any contamination, such as snow or ice of significant
importance.
