Water Connection Assistance Program

Water Connection Assistance Program

This page provides information on DuPage County’s Water Connection Assistance Program. It includes general information on the program, eligibility requirements, application information, reference materials, and contact information.


On May 24, 2022, the DuPage County Board allocated funding for the Water Connection Assistance Program (“WCAP”). The purpose of WCAP is to encourage DuPage County homeowners to convert to a clean, reliable source of drinking water. WCAP is designed for County homeowners who are currently served by private or community wells and who want to connect to a public water utility for Lake Michigan water. WCAP encourages this switch by partially subsidizing these connection costs. WCAP is funded through the American Rescue Plan Act. The American Rescue Plan Act of 2021 (ARPA; P.L. 117-2) was signed into law on March 11, 2021 to provide COVID-19 relief and economic stimulus. The County has received $179,266,585.00 from the American Rescue Plan Act and has allocated $1,000,000 for WCAP eligible expenses. All WCAP payments must comply with ARPA requirements.


DuPage County’s Department of Public Works (“PW”) is administering WCAP. It will be working with the Finance Department, County Audit, the DuPage County Health Department and numerous other departments to review, approve, and process the payments. The Program is scheduled to start accepting applications through its online portal on August 24, 2022. No applications will be accepted after December 1, 2024 pursuant to ARPA spending deadlines.

WCAP is reimbursement-based. Once homeowners have completed their water connection projects and passed inspections, they will submit their reimbursement requests through the WCAP online portal. Homeowners may request reimbursement of up to 50% of their project costs, but total reimbursement costs may not exceed $3,000. Project costs must be substantiated/documented in information uploaded into the WCAP online portal.

Funding will be awarded for complete applications on a “first come, first serve” basis. Homeowners will not be considered for funding until applications are complete and approved; therefore, the County strongly recommends that online portal applications are as complete as possible. This will help avoid delays in approval and improve the likelihood of funding.

A high-level overview of the steps in the process are:

  1. Homeowner completes project
  2. Homeowner passes inspection
  3. Homeowner submits WCAP application online
  4. Staff reviews applications and follows up if needed
  5. Staff approves WCAP application County processes payment and issues reimbursement check
