Overflow Action Day

The Metropolitan Water Reclamation District issued an “Overflow Action Day,” asking residents to minimize their water usage to help reduce flooding.

The MWRD asked residents to:

These requests were made to ensure sewers don’t get backed up during the storms and cause flooding into streets and basements.
