Metropolitan Water Reclamation District of Greater Chicago

Become a Multi-County Municipality

Article 2 of the WMO allows multi-county municipalities to adopt and enforce the stormwater ordinance of a collar county. Multi-county municipalities interested in adopting and enforcing a collar county's stormwater ordinance are required to submit a letter of intent to the District. A sample letter of intent is accessible through the following link.

Sample Letter of Intent

If your municipality intends to adopt and enforce a collar county's stormwater ordinance, please submit a letter of intent to:

Catherine A. O’Connor 
Director of Engineering
Metropolitan Water Reclamation District of Greater Chicago
100 East Erie Street
Chicago, Illinois 60611

After an interested municipality adopts a collar county’s stormwater ordinance by reference, a subsequent intergovernmental agreement between the municipality and District will effectuate the rights and responsibilities of such an arrangement. A sample intergovernmental agreement is accessible through the following link.
