The recycled water supplied by TopAq is designated by the EPA as Class A recycled water. It has been recycled from wastewater that has previously undergone purification at Melbourne Water’s Eastern Treatment Plant. Further treatment is then provided by the latest ultrafiltration technology to remove harmful pathogens (bacteria, viruses and parasites).
These processes make the Class A recycled water safe for a variety of uses, including horticulture, residential, industrial and recreational applications.
Class A recycled water can be used for direct watering of leafy vegetables that are eaten raw, such as lettuce, celery, spring onions and carrots.
It can also be used in residential developments for toilet flushing and garden watering, and for irrigating golf courses, parklands and sporting fields
The
use of Class A recycled water is prescribed
in the
EPA Guidelines for Environmental
Management: Use of Reclaimed Water,
2003, and endorsed by the Department
of Human Service for unrestricted
use, provided it is used in accordance
with the guidelines. The Environmental
Improvement Plan further sets out
these uses in a way that promotes
sustainable use and development, and
sound environmental management.
