Sanitary Sewer Emergency


Monday - Friday 7 am - 3 pm: 217.789.2244
All Other Times: 217.789.2246

Report that you are experiencing a sanitary sewer emergency. Back up sewer lines, line breaks, sewage odors and overflowing manholes are considered an emergency.

A sewer maintenance crew will be dispatched to investigate the cause of the sewer problem. If the cause of the problem is determined to be within the private lateral and not within the City sewer main, you will be instructed to contact a plumber or sewer cleaning service. The City does not have the ability to clean private lateral lines.

Public Notification

The City of Springfield is required through the USEPA Administrative Order to post information concerning Sanitary Sewer Overflows (SSO's). SSO's are defined as when sewage leaves the sanitary sewer system due to a problem or failure of the city owned sewer main. Basement backups caused by problems in private laterals are not considered SSO's. Residents in affected areas are cautioned to avoid contact with untreated sewage.
