CSIRO claims to have developed a practical and sustainable method to test greywater treatment technologies, paving the way for the establishment of a national testing standard.
The partnership, between CSIRO’s Water for a Healthy Country program and the Smart Water Fund, has created a method that involves the use of a synthetic formula.
According to the parties, this formula contained a mix of soap, toothpaste, washing powder and other personal products, combined with high levels of bacteria, viruses and protozoa. After this was fed into a piece of technology, the output was tested against the Australian recycled water standards.
The partners say at the moment, there is no standard national testing method for greywater systems. The states and territories each have their own legislation.
A national regime, according to the researchers, would simplify the processes for manufacturers and increase the adoption rates for recycled water.
