Clean waterways are a priority for Mishawaka. We have implemented many projects to improve water quality in the river and to reduce combined sewer overflows (CSOs). These efforts include expanding and modernizing our wastewater treatment plant and improving the sewer collection system. Mishawaka has reduced annual CSO volume by 98.7 percent from our baseline year of 1990.

Federal law (40 CFR 122.38 (c)) requires CSO communities that discharge into tributaries to the Great Lakes to offer public notifications when CSOs are discharging. An initial notification of a CSO event must be communicated within four hours of an overflow beginning and a supplemental notice within seven days of the event that gives estimated CSO volume along with overflow start and stop times. A notification summarizing the past year’s CSO activity will be published annually on the City’s website by May 1 of each calendar year.

To receive notifications about CSO events in the City of Mishawaka, follow the Mishawaka CSO Alerts account (@CSOAlerts) on Twitter. You can also visit the Mishawaka CSO Alerts feed on Twitter directly.
