  20. How can INDA help the wastewater industry… its ratepayers… and its consumers? • Real lab testing is needed • Not just a problem for OCSDand California • Non woven product “re-formulation” needed? • “Compounds of concern” in nonwovens? • Improved labeling for consumersand industrial users

  21. Next Steps? Other options and ideas?Put Flushables in the Trash, Not the Sewer • Sewers and treatment plants are not a cost effective mean to send rags to a landfill…the trash can is • Help prevent sewer spills and reduce O&M costs • Help provide better functioning sewers and treatment systems • Consumer education programs: inda.org, edana.org, and paper towel information at tappi.org Graphic courtesy of King County
