
Except for person/s responsible for lifting and positioning of the tank in the
excavated hole, there must not be any person within 20m of the installation site
during the lifting and positioning of the tank. Excavation Instructions show
excavated walls to be perpendicular. However, depending on the soil conditions,
the excavator may need to batter or retain the side walls to ensure they don’t
cave in during installation.

Level the base of the hole using an excavation bucket with a laser level attached.

Ensure that the excavated ground or base material is capable of
carrying loads of approximately 8 tonne.

The ABS5000 must be level in both inflow/outflow direction and 90° to the
inflow/outflow direction (<1° deviation).

Backfilling - Use sand or excavated material/spoil with maximum particle size
of 300mm. Backfilling of excavation to be completed in not more than 500mm
equally distributed layers around the tank perimeter. Ensure that sand or
excavated material does not fall on the lid of the ABS5000 as this will fall into
the system through the manholes and clog the system and irrigation pump.
Ensure that the backfill material is kept at least 100mm below the surface of
the systems lid.

Evenly fill each system with approximately 5,000L of water through the
centre Chambers to prevent movement through the ground as the
water pressure enters the system.

Organise drainage contractors to connect the main sewer line to the
system and between Tank 1 & 2. The drainage connection is a standard
100mm PVC sewer inlet.
