The International Water Services Flushability Group (IWSFG) has released a set of Publicly Available Specifications for flushable products including wet wipes.
The specifications were developed by the water industry to provide clarity on what can be flushed. They include a set of five criteria for a product to meet before they are suitable for flushing down the toilet.
The specifications underwent two rounds of public comments, including from wipes manufacturers, to ensure the standards were realistic and acceptable worldwide.
Water Services Association of Australia (WSAA) is leading the development of a national standard through Standards Australia that will define the criteria for material suitable for toilet flushing, along with appropriate labelling requirements.
