Combined Sewer Overflow (CSO) Program

Our sewer system, like many in cities throughout the United States, was designed to carry both sewage and rainwater - with relief points that overflow when too much rainwater enters the system.
 
During dry weather, sewage flows safely through the sewers to our wastewater treatment plant. However, during rainstorms or snowmelt the incoming stormwater can overwhelm the sewers and cause raw sewage to overflow into the St. Joseph River, Elkhart River and Christiana Creek.
 
During wet weather, overflows can occur at up to 29 locations along our waterways, and can be triggered by as little as two-tenths of an inch of rainfall or snowmelt.
  
Elkhart has developed a Plan to capture and treat more of these overflows. 
  
Elkhart strives to inform our citizens that caution should be taken when choosing to engage in recreational activity on or in the surface water bodies of our community during and after a rainfall or snowmelt event. The link below provides more information about how the City meets this goal.
