ABOUT THE GREYWATER SAVER
The Greywater Diverter Vessel Assembly, sold under the product
name"Greywater Saver " is an Australian owned &
patented product that provides a reliably and acceptable long-term
greywater reuse solution, so it can be used to sucessfully
reduce both water consumption and wastewater for disposal.
The Greywater Saver:
• has a nation-wide Australian Plumbing Safety Type
Test authorisation and acceptance through the National Certification
of Plumbing and Drainage Products Scheme, administered by
Standards Australia.
• is approved by state & territory wastewater regulators
for greywater reuse in sewered and unsewered areas. See Approvals
page for more details of these.
• costs little to purchase, nothing to use and will
pay for itself in water savings.
• is a miniature system with no large tanks, no electric
pumps/switches, no expensive maintenance contracts and requires
no chemical additives.
• requires only several minutes input by users to regularly
clear the stainless steel mesh filter of trapped lint and
hair etc.
• has a failsafe overflow feature to ensure that even
if users forget to clean the filter or if the system becomes
overloaded greywater will automatically bypass the system
and discharge to the sewer without hindering the free flow
of greywater out of the building or impacting on the health
and amenity of the building's inhabitants.
• diverts greywater for garden irrigation rather than
disposing it to the sewer or onsite wastewater system, thereby
conserving water and reducing the environmental impact and
volume of wastewater being disposed to the environment.
The Greywater Saver has a manual gate valve, which users can
open or close to select whether their greywater is diverted
for garden irrigation or disposed to the sewer or onsite wastewater
system. The Greywater Saver has a removable stainless steel
mesh filter basket to filter out larger particles from the
greywater such as lint and hair, and removal of the stainless
steel mesh filter for simple regular cleaning by users is
through the unit’s removable gas-tight screw cap access
cover.
Filtered greywater flows under gravity from the diverter vessel
in 50mm pipes to a chosen number of piped irrigation trenches
(a 90mm pipe with 20mm holes surrounded by rock aggregate)
located just beneath the surface of garden beds. Even distribution
of filtered greywater to each of the piped irrigation trenches
is achieved by use of the purpose made Greywater Saver Flow
Splitter 50mm Y junction fittings. These fittings specially
designed to split a single stream of filtered greywater under
gravity into two equal volume streams that in-turn may each
be further split into two streams as might be needed for a
particular garden’s layout. The Flow Splitter fitting
fits standard 50mm DWV pipe, and can be used wherever there
is a need to evenly disperse a single stream of liquid into
multiple streams under gravity. This gravity Y junction irrigation
arrangement uses similar gravity distribution principals to
those refered to and promoted in American Graywater literature
as " Branched Drain Graywater Systems or sinply Branched
Drains ".
HOW DOES THE GREYWATER SAVER DIFFER
FROM PREVIOUS GREYWATER SYSTEM TYPES?
Previous greywater reuse systems and products have never been
particularly successful or accepted because they either:
- have been illegitimate ad-hock plumbing type configurations
that did not satisfy the established standards demanded by
the plumbing and health regulators to be approved/authorised,
and most provided little or no contingency against failure
and human exposure to the greywater or the escape of sewer
gases, or;
- were acceptable to regulators but were too expensive for
users to purchase, operate and maintain compared to the value
of water savings they provided, and were typically large below
ground tank systems that incorporated disinfection, pumps,
failure alarms, sewer anti-backflow fittings and other components,
many of which required users to enter into ongoing expensive
maintenance contracts with licensed contractors, or purchase
replacements parts which alone exceeded the value of water
saved.
WHAT APPROVALS ARE REQUIRED FOR
A GREYWATER SYSTEM'S USE IN AUSTRALIA?
Before a greywater reuse system can be used in Australia,
the system must first have the necessay authorisation and
acceptance from the state or territory onsite wastewater disposal
regulator and/or the state or territory plumbing regulator.
This approval is not one that the user is required to obtain
but is the responsibility of the system manufacturer to obtain
before offering the product for sale.
Whilst a number of greywater reuse plumbing products continue
to be promoted & sold over the web, many play with words
in failing to advise prospective purchasers that they can
not actually be legitimately used because they are not authorised
for use. Purchasers of these products can therefore find themselves
in the situation of not being able to find a plumber willing
to risk their plumbing license to install such an unauthorised
product and are then left with the problem of either not being
able to use the product they purchased in good faith or end
up attempting illegal plumbing works themselves. Always ask
if the product being offered is approved by your state wastewater
and plumbing regulators for installation and use.
WHICH STATES OF AUSTRALIA CAN
I USE A GREYWATER SAVER?
The Greywater Saver has a Standards Australia Plumbing Safety
Type Test Approval and as such is authorised for use as a
plumbing product Australia-wide under the National Certification
of Plumbing and Drainage Products Scheme, administered by
Standards Australia. The Greywater Saver is in fact the first
and only greywater reuse plumbing product to ever achieve
that national acceptance.
More information about the National Certification of Plumbing
and Drainage Products Scheme can be found on the Sydney Water
Website at: http://www.sydneywater.com.au/html/yourBusiness/pdf/PlumbingPRODUCTCERTIFICATION.pdf
However, as indicated above greywater reuse systems also require
authorisation from state and territory wastewater regulators.
In this regard, the Greywater Saver system has full authorisation
for use in both sewered and unsewered areas of WA, SA, NSW,
Vic, ACT & NT and in the unsewered areas of QLD and Tasmania.
Legislative changes to permit greywater reuse in the sewered
areas of QLD is now being progressed by the QLD regulators,
whilst Tasmania's Regulators currently do not allow greywater
recycling in sewered areas.
ARE ANY OTHER APPROVALS REQUIRED?
Before even an authorised greywater product can be installed
or used it is generally a requirement that the local government
or other local wastewater regulator issue an approval. This
is however not a requirement in all states. Whilst obtaining
this is quite a simple exercise this is nevertheless the responsibility
of the property owner. Ask your local government Environmental
Health Officer or Plumbing Inspector for advice about this.
