Wastewater Practitioners

Since 2004, INDA and EDANA have been collaboratively working with the Wastewater Industry across Europe and the United States in the shared objective of reducing the amount of non-flushable material in the wastewater stream.

The labeling Code of Practice (2017) includes guidelines on when and how to use the ‘Do Not Flush’ symbol.  For products that have a high likelihood of being flushed, but that are not designed to be flushed, the “Do Not Flush” symbol should appear clearly on the packaging as outlined in the labeling Code of Practice.

We believe educating consumers on the proper disposal method for our products is one of the most important things we can do to help ensure that only those products designed and marketed to be disposed of via the toilet are flushed.  This is why we created the Code of Practice and ‘Do Not Flush’ symbol which accompany the Flushability Guidelines.  

We developed the nonwovens industry’s first edition of the Guidelines for Assessing the Flushability of Nonwoven Disposable Products in 2008.  Now, Edition Four of the Guidelines, in conjunction with the labeling Code of Practice (2017), provides the most comprehensive guidelines available for assessing flushability.

We recognize that our industry, the habits and practices of individuals, and the needs of wastewater operators change over time, and therefore, Edition Four of the Guidelines is a living document.  We gather feedback from all stakeholders and use it to review and update the Guidelines as needed.  INDA and EDANA are committed to continuing to work collaboratively with wastewater practitioners around the world to help reduce the amount of non-flushable material in the wastewater stream. As an industry, we are also dedicated to continuous improvement in product performance to meet the needs of the consumer and the wastewater industry alike.

February 2019 - EDANA position on Water UK’s flushability specification and ‘Fine to Flush’ initiative

EDANA and wipes manufacturers were surprised and disappointed to learn of Water UK’s publication of the WIS and new ‘Fine to Flush’ initiative.

  • EDANA considers it unnecessary, and possibly counterproductive, to launch a separate protocol which will confuse the market. It’s not clear- particularly given the close collaboration on this issue in 2018 - why Water UK decided to launch this protocol. One devised without proper consideration from the manufacturers of the products in question.
  • This WIS is presented as a solution to fatbergs. Education leading to the reduction of the improper disposal of fats, oils, grease and wipes is the solution to fatbergs.
  • GD4 compliant flushable wipes do not contain plastic. Water UK state that their standard will finally assure plastic free flushable wipes, yet this is already a stipulation in the industry standard.
  • The WIS lacks the solid scientific background of GD4, garnered over the years of extensive research and testing. Only one lab can perform the WIS tests and there a lack of information about reproducibility and repeatability of the protocol.
  • Focusing on replacing proven standards while there is proof that the real problem is caused by the 90% non-flushable wipes, is misleading.

    EDANA continues to promote GD4 as the proven industry standard for flushable wipes and strongly advocate the industry guidelines for correct disposal labelling of non-flushable wipes.

  • GD4 has proven to be effective but is by itself insufficient to remedy the issue of blockages. Water UK’s own 2017 study of sewer blockages found that less than 1% of the blockage material was identified as products designed to be flushed1. In fact, in over 50 blockages no GD4 compliant flushable wipes were identified. The vast proportion of wipes found in the blockages were of the non-flushable type which had been incorrectly disposed of.
  • GD4 (including the labelling Code of Practice) is the basis for national legislation or standards in Belgium and Spain and is in the process of being adopted by Waste Water authorities in
    other European countries. 

Next Steps

Consumer education to reduce and eliminate the flushing of products that shouldn’t be disposed via the toilet will have the largest impact for reducing sewer blockages. This approach is echoed in the very first recommendation of the Water UK study: Public/press communications should target the inappropriate disposal to sewer of nonflushable products”.

Wipes manufacturers firmly believe that close collaboration with other relevant parties, most notably the water bodies, is the optimum method to achieve products that meet consumer needs, agree on standards that mitigate their impact and align on communication initiatives that inform consumers.
