Report a Sewer Backup

Sewer Backup? Call us FIRST at: (513) 352-4900

MSD's Sewer Backup Response (SBU) program offers 24/7 reporting of sewer backups from the public sewer.  There are two ways to report your sewer backup: 

  • Call (513) 352-4900 24/7
  • Submit an online report (see below)


MSD representatives monitor online sewer backup reports from 7 a.m. until 8:30 p.m. every day, 7 days a week. If you submit an online sewer backup report after 8:30 PM, MSD will not receive your request until 7 AM the next day.

If you would rather not wait until morning, you can receive service for a sewer backup during these overnight hours. Please phone MSD at 513-352-4900 to speak with an MSD representative.

Please provide your "Contact Information" below.
Email is not required, but it is helpful!
