CWT collection well systems may initially
appear to be a step backwards. Site treatment of
human waste at locations with zero services is
an admirable concept... the reality is that most
site treatment systems (composters) require
committed management and have liquid discharges
on site. CWT collection well systems have Zero
Liquid Discharge on site and are easily managed. |
| Compliance |
- CWT 3000L and CWT 10000L collection wells
are AS1546.1 (2008) compliant and accredited.
- The CWT Quality System is accredited by SAI
Global - License SMHK 20007.
- NSW Health Certificate 012-20007
- QLD compliance with Environmental Protection
Regulation 1996
- NT Approval Number 08/05
- The melding Pureablue stainless steel pedestal
is AS1548.1 and AS1547 compliant
|
|
Management |
- A site specific Management Plan is created
for each installation in the acquisition phase.
This takes in to account anticipated usage,
seasonal fluctuations, and capacity of local
waste contractors.
-
All waste is removed from site by CWT endorsed
and State government registered sullage waste
contractors.
-
All OH&S issues involving staff working with
human waste are by-passed
-
Odour management is by a benign soy based
additive that is dosed in to the system at the
weekly servicing of the facility. The dosage
regime is specified in to the Management Plan.

Liquid Waste |
- Black water is removed from site.
The endorsed contactor will have obligations to
dispose of the waste at a suitable facility. -
Facility managers routinely remove other waste
from site…cans bottles, and putrescible waste...
for disposal at municipal waste facilities...why
should the management of blackwater likewise be
problematic?

Vandalism |
- All Fabranamics products are of concrete and
steel. This style of construction is an absolute
must for public use facilities in remote
locations.
-
The CWT collection wells are engineered to act
as the footing of the building. This is not
possible with a plastic tank.
-
The CWT collection well can be placed up to 90%
below ground level... advantageous with the
disabled access design of the toilet building -
no ramps required - entry to building at just
above ground level.
-
A design consequence of collection wells is that
at the early stage of the collection cycle, the
collection well is only partially filled.
Floatation and restraining plastic tanks is
therefore a major problem, as is tank side wall
collapse when not at full capacity. Flotation of
the CWT tanks is assisted by the natural mass of
concrete, plus a ground anchor system. The
inherent strength of the concrete walls are
engineered to resist side wall collapse when
only partially full.
