The company stated that crews have been actively working to address the sewer issues on Sunday and Monday, but officials noted that the sewer collection systems are currently at capacity due to the volume of rain.
It will take time for the systems to recover once the rainfall subsides, the company said.
“We appreciate your patience,” said Terry Mackin, communications and external affairs representative for Illinois American Water.
Residents in the affected areas are advised to stay informed and exercise caution as crews continue mitigation efforts.
