The Chicago region has water and flooding issues. One sign of this is an email I received two days ago during a rainy week and ahead of more rain:

I do not know how many people are on this mailing list or how many people would change their water use patterns based on an email. However, I can see the point: if capacity is reduced and the Metropolitan Water Reclamation District of Greater Chicago knows about it, why not ask?
At the same time, some might wonder why there is a need for this. Doesn’t the region have a modern marvel intended to provide relief from flooding? Haven’t these issues been addressed over the decades?
As the region continues to grow and experience more development, these water issues will likely grow. Pursuing different solutions could help as could changing usage patterns.
