Do Not Flush - No Wipes in the Pipes

Do Not Flush - No Wipes in the Pipes Remember, no wipes in the pipes! Only toilet paper is truly flushable, despite what labels may claim. Anything else is not designed to break down, can clog home pipes and city sewers and must go in the trash instead. Here’s a friendly reminder on what not to flush, (including so-called "flushable wipes") to avoid clogs. Please report any public sewer issues to our Sewer Maintenance Operations Center, at 614-645-7102. - learn more
