Division of Water Reclamation - Combined Sewer Overflow Notification

Current overflow sites are listed by waterway and location.



There are no combined sewer overflows at this time.




Due to heavy or prolonged wet weather activity, a portion(s) of the City of Toledo's combined sanitary and storm sewer collection system and existing underground storage facilities can reach capacity. A Combined Sewer Overflow (CSO) can occur in one or more locations within Swan Creek, Ottawa River and/or the Maumee River where the City is permitted to discharge during wet weather. The general public is advised to avoid these waterways for up to 48 hours after a combined sewer overflow event. For more information please contact: #419-727-2600.

Multiple CSO locations may be relieved simultaneously or at different times during wet weather events. The City of Toledo does not provide details of CSO activities until fully investigated after the conclusion of the wet weather event.

Please Note: A wet weather event may last several days.

Details regarding wet weather overflows will be available here within seven (7) days of the conclusion of the event.
