Rainfall Events Prompt Warnings About Combined Sewer Overflows (CSOs)

By Laura O'Brien on 5/30/18 4:25 PM

Emails Serve as Notifications That CSOs May Occur

INDIANAPOLIS – Steady rain events, such as today’s rain resulting from Subtropical Storm Alberto, cause the combined storm and wastewater sewer system in Marion County to overflow into area waterways when as little as a quarter-inch of rain falls. CSO warnings are issued via email by Citizens Energy Group whenever the weather forecast calls for that amount of rain or more. These warnings are mandated under Citizens’ Consent Decree with the U.S. Environmental Protection Agency.

Citizens’ CSO warnings mean the public should avoid all contact with waterways downstream in the CSO areas (listed in the email) for four days. No further action is needed.

The DigIndy Tunnel System, a 28-mile network of underground tunnels now under construction, will nearly eliminate sewer overflows in Marion County by the year 2025. The first 10-mile segment of the tunnel system opened at the end of December and has already prevented more than 264 million gallons of raw sewage from entering our waterways.
