Site
Preparation
It is best practice to prepare the excavation for the Vortceptor separation
chamber first. The Vortceptor separation chamber is the blue fibreglass
vertical tank, which we will refer to as ‘the Vortceptor’. The excavation for
the Diversion Chamber (the rectangular precast concrete chamber) follows
afterwards.
YES / NO
Prior to installation, the inlet pipe run would typically be installed, within one
or two pipe lengths prior to the diversion chamber.
YES / NO
Vortceptor
Installation
Always physically check measurements on the Vortceptor prior to installation. YES / NO
The Vortceptor excavation should be no greater than required, this would
be 1000mm oversized or to suit shield sizing. This is with due regard to the
amount of backfill to be used under and around the tank.
YES / NO
Install a 150mm thick, compacted base. This can be either a concrete blinding
or compacted crushed rock layer.
YES / NO
Lower the Vortceptor into the excavation, ensure no rocks or sharp objects fall
into the hole and damage the tank.
YES / NO
Level and adjust the Vortceptor to suit the main drain pipework and the
Diversion Chamber inlet void. The invert levels of the inlet and outlet
pipework is to match the invert of the inlet and outlet chute of the Vortceptor.
(The inlet and outlet chute is the rectangular flanged opening on the side of
the Vortceptor)
YES / NO
Fill the tank with water up to the invert of the inlet - the volume will depend on
the specific Vortceptor.
YES / NO
Encase & backfill the outside of Vortceptor with an engineer specified material
– such as graded gravel aggregate, or crushed recycled concrete, or cement
stabilised sand.
YES / NO
In installations when the tank is located in an area subject to high water
table or trapped ground water, the tank must be completely encased in
unreinforced concrete, up to the specified height above the Vortceptor base,
and at the minimum specified width beyond the perimeter of the Vortceptor
base. Refer to SPEL Stormwater for recommended concrete dimensions and
volumes to withstand buoyancy forces.
