This came up on a separate thread, and it reminded me of a recent article in the Times! Apparently flushable wipes have been creating a growing number of problems in public sewage systems:

<< Wet wipes, which do not disintegrate the way traditional toilet paper does, have plagued Hawaii and Alaska, Wisconsin and California. Sewer systems have been stuffed in Portland, Ore., and Portland, Me. Semantic debates have visited Charleston, W.Va., challenging the latitude of “flushability.” “I agree that they’re flushable,” said Tim Haapala, operations manager for the Charleston Sanitary Board. “A golf ball is flushable, but it’s not a good idea.”

The consummate cautionary tale is that of London, where in 2013 a collection of wipes, congealed cooking oil and other materials totaled 15 tons, according to Thames Water, the utility company that removed it. It was known, like some previous occurrences, as the fatberg. “We reckon it has to be the biggest such berg in British history,” Gordon Hailwood, an official with Thames Water, said at the time. >>

According to the article, you shouldn't flush baby wipes even if they are marketed as flushable! I had no idea...
