Who We Are
Internationally, water service providers, and the associations and organizations representing them, share a common goal to reduce the problems caused by the inappropriate disposal of consumer products down the toilet. The International Water Services Flushability Group (IWSFG) is a group of water associations, utilities, and professionals 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. The IWSFG has developed Flushability Specifications for evaluating whether consumer products are safe to flush.
NEW: A study, Defining ‘Flushability’ for Sewer Use, on the characteristics of 101 commonly flushed consumer products was published on March 31, 2019 by Ryerson University. Products were tested for toilet and drainline clearance, disintegration under the IWSFG specification, and fiber composition. The product packages were also evaluated for compliance with the labeling Code of Practice issued by nonwoven products industry associations for labeling non-flushable products.
