Installation:
P6-P12 Tri-cel Bio System:
Site conditions will determine the procedure of installing the unit. A partial concrete base
is required for a dry site, whereas a complete concrete backfill may be required for a wet site
and also where the unit may be subject to super imposed loads. Lifting hooks are supplied with
the Tri-cel bio system to assist in lifting the unit into position. Care must be taken to avoid
any damage to external flanges or pipe work when lowering the unit into the trench
It is important to ensure that the unit is fully supported and completely level when installed
and the lip of the lid should sit flush with finished ground level. When installation is complete,
the system is filled with water, plumbed to the sewers etc, the electrical installation must then
be completed. Our site crews will return to site to commission the system.
For a detailed method of installation, plumbing and wiring of the unit, please refer to our handbook.
P12 - P500 Tri-cel Bio System:
These tanks are installed below ground level and completely surrounded with granular material. When
excavation the area for the tri-cel bio system, a minimum clearance of 450mm is required at each
side of the unit and also between adjacent units. Site conditions will determine how the tank is
secured underground. In dry sites, we recommend anchoring the unit, either by a reinforced concrete
slab or a concrete dead-man anchor. For wet sites a concrete installation may be required or an increased
number of dead-man anchor straps. Strapping must be located to the rib of the unit and must be tightened
until snug, but not to deflect the unit. A backfill comprised of crushed stone or pea-gravel is then used
to surround the unit. Its is important to ensure that the unit is dead level and aligned properly with
the pipe work. The air blower and monitoring systems will be located in the kiosk situated close to
the unit.
Please refer to the handbook for a detailed guide to installation.
