Inflow/Infiltration Grant Programs

The 2020 Municipal I/I Grant Program has been approved and consists of $5M in bonding bill funding for the purpose of providing grants to municipalities for capital improvements to public infrastructure to mitigate I/I. The Grant Administrator will begin to accept applications in late February 2021.

The I/I Grant Program is available to communities in the Metro area that have been recognized by the Council as an excessive I/I contributor, or have a measurable flow rate within 20% of the allowable flow limit.

A virtual information session on the 2020 grant program will be held on Wednesday, January 27, 2021 at 11AM. Registration is required; register at the 2020 Municipal I/I Grant Program Information Session page.
