Flushable Wipes and Other Non-Dispersible Products

Print E-mail

Clean water agencies across the country are increasingly dealing with problems caused by wipes and other products that do not break down quickly in the sewer system. Utilities are spending millions of dollars to respond to overflows, clean these products out of their pumps and other equipment, and to replace equipment that should have had more useful years of service.  NACWA, the Water Environment Federation (WEF), and the American Public Works Association (APWA) are working together to address this problem.  This page provides resources and references related to the wipes issue.

Given the far-reaching impacts of wipes and other products on clean water agencies, NACWA launched a new campaign to protect pipes, pumps, and plants by reducing the harmful materials that are flushed or drained into the sewer system. These products include wipes, pharmaceuticals, paper towels, feminine hygiene products, dental floss, FOG (fats, oils, and greases), as well as product additives such as triclosan.

What You Can Do To Help

Does your utility have problems with wipes and other non-dispersible products, and would you like to help with our national advocacy efforts? If so, please take photos of the problem and complete a Non-Dispersibles Incident Report.  Two versions of the report are available:

Completed forms should be returned to John Pastore, Executive Director of the Southern California Alliance of Publicly Owned Treatment Works (SCAP), at This e-mail address is being protected from spambots. You need JavaScript enabled to view it or fax #760-479-4881.  John is compiling a national database of non-dispersible incidents (you do not need to be in Southern California to use this SCAP report form).  Collecting as much information as possible about these incidents is vital to the efforts of NACWA, WEF, and APWA.  We appreciate your help!



WEF hosted a webcast on June 19, 2013 that provided an overview of the problems caused by non-dispersible products and the actions taken thus far by WEF, NACWA, and APWA.  A recording of the webcast is available at www.wef.org/FlushableorNot/ and the slides from the webcast may be downloaded here icon-pdf.
