Water New Zealand is a member of the International Water Services Flushability Group (IWSFG). This is a group of water associations, utilities, and professionals are seeking to provide clear guidance on what should and should not be flushed down the toilet to protect customers, wastewater systems, their workers, and the environment.
This objective is supported by Publicly Available Standards (PAS)
documents setting out the test protocols and other information supporting and
referenced in the standard.
This group has created an international PAS to determine the
requirements of what is flushable. PAS (3) was published in July 2018.
PAS1:
Criteria for Recognition as a Flushable Product
PAS2:
Terms and Definitions
PAS3:
Disintegration Test Methods - Slosh Box.
