Contain 1 or more tanks.
Ensure that each tank is 100% level.
Connect pipe work, as required.
Ballast the tank with water. Refer to detailed installation
Commence gravel backfilling in 300mm layers approximately up to
50mm over the cylindrical body of the tank, ensuring tank and any
pipe work is properly supported.
Commence concrete backfilling in 300mm layers approximately up to
the pipe work level, ensuring tank and any pipe work is properly
supported.
Continue backfilling with gravel up to 50mm over the cylindrical body
of the tank
Mount and seal any turret extensions.
Complete backfilling with topsoil up to the max ground level line
indicated on the plant. The surrounding finished ground level
should never be higher than the “max ground level line”.
Compact evenly around the tanks to ensure it’s is properly supported.
An access chamber should be installed before and after the tank
for sampling and to assist in clearing possible blockages
If sewage consists of high quantities of grease a grease trap should be
installed prior to the plant.
Note:
The option of a reinforced concrete slabs or deadman anchor may also be used on wet sites. This should
be designed by an on-site structural engineer to suit site conditions.
10.3 Detailed installation information:
The Tricel Duos should not be installed in an area subject to flooding or excessive water runoff. The area
around the Tricel Duos should be adequately drained, to permanently remove ground water and surface
water from the proximity of the tank. The Tricel
Duos system is not suitable to be used in water logged sites,
where the ground water may rise above the inlet level.
