Sewer Overflow Discharge Information

The following Geographic Information System map shows known Combined Sewer Overflow (CSO) and Sanitary Sewer Overflow (SSO) discharge locations along various waterways and overflow information at these locations from the Columbus sewer system. CSOs are discharges of a combination of stormwater and wastewater from the city�s older combined sewer system. SSOs are discharges of wastewater from the sanitary sewer system, typically during wet weather when flows may temporarily exceed capacity. For general information about SSOs and CSOs, please visit our Frequently Asked Questions about SSOs and CSOs web page.
To avoid any possible health effects from a sewer overflow, please avoid contact with the water near an SSO or CSO discharge location, particularly after a rain storm. This includes activities such as boating, wading, fishing and swimming. Be aware that swimming in local waters is prohibited by Columbus City Code and is also considered a dangerous drowning risk in many areas due to low-head dams and utility crossings. Signs are posted along local waterways identifying the sewer discharge locations. For more information on possible health and environmental impacts of overflows, please visit the following U.S. EPA web site.
The discharge data available on this web site is based on consent decree requirements and is updated at least once per month, usually after the 15th, to reflect any known activity for the previous month. Posting of data for SSOs began in 2004 and CSO data began in 2005.
To report a suspected overflow, please call the 24-hour Sewer Maintenance Operations Center at (614) 645-7102
