The complaints have prompted a renewed look at solving the problem.
The Association of the Nonwoven Fabrics Industry, the trade group known as INDA, recently revised voluntary guidelines and specified seven tests for manufacturers to use to determine which wipes to call flushable. It also recommends a universal do-not-flush logo — a crossed-out stick figure and toilet — be prominently displayed on non-dispersible products.
The wastewater industry would prefer mandatory guidelines and a say in what's included but supports the INDA initiatives as a start. Three major wastewater associations issued a joint statement with INDA last week to signal a desire to reach a consensus on flushability standards.
"If I'm doing the test, I'm going to throw a wipe in a bucket of water and say it has to disintegrate," said Rob Villee, executive director of the Plainfield Area Regional Sewage Authority in New Jersey.
Nicholas Arhontes, director of facilities support services in Orange County, Calif., has an even simpler rule for what should go down the toilet.
"Only flush pee, poop and toilet paper," he said, "because those are the only things that sanitary sewers were really designed for in the old days."
