Opportunity Overview
The Wisconsin Department of Natural Resources is accepting Cycle B applications for its Underserved Drinking Water System Grant Program. The program helps small Other-Than-Municipal community (OTM) and nonprofit Non-Transient Non-Community (NN) public water systems return to compliance with the Safe Drinking Water Act. Qualifying nonprofit NN systems can include schools and daycare centers that are not served by municipal water.
Funding and Deadline
Wisconsin DNR reports approximately $1.3 million available. Eligible projects may receive up to $240,000 per public water system, and the federal cost-share requirement is waived, allowing funding for 100% of eligible project costs up to the award cap.
Applications are accepted on a rolling basis through September 30, 2026, or until funds are exhausted, whichever comes first. The current DNR program page does not state a specific closing time or time zone.
Eligible Applicants
The applicant must be the owner or authorized representative of an eligible small OTM or nonprofit NN public water system serving fewer than 10,000 people. The system must have an active eligible Maximum Contaminant Level violation, Treatment Technique violation, or Action Level Exceedance. Nonprofit NN systems may include government entities, school districts, and qualifying 501(c)(3), 501(c)(4), or 501(c)(6) organizations that do not lobby.
Eligible Uses
Examples include technical, managerial and financial assistance; non-routine testing; new or improved source water; consolidation; transmission and distribution improvements; storage; treatment; and other DNR-approved costs necessary to address the eligible violation or exceedance.
Application Requirements
Applicants must obtain a Unique Entity ID (UEI) and submit the current UDWS Grant Application Form 8700-829, UDWS Environmental Review Form 8700-830, a W-9, and, for nongovernmental nonprofit NN systems, the required IRS tax-exempt affirmation letter. Complete applications are submitted by email to DNRUnderservedGrants@wisconsin.gov.
Atlas Fit Analysis
Atlas Opportunity Score: 74/100. The program is highly relevant to Wisconsin school and community infrastructure where a qualifying school, daycare, or other nonprofit NN system has an active drinking-water compliance issue, but applicant eligibility is narrow and contamination-specific.
N9+ Fit: 0/100. QC Healthcare Fit: 0/100. Direct Vendor Fit: 0/100. The funded work is drinking-water compliance and infrastructure, not remote clinical examination, telehealth, medical-device deployment, or physician coverage. Atlas should not force an N9+ or QC Healthcare pathway into this opportunity.
Verification Note
The live Wisconsin DNR program page states that Cycle B is currently open and applications are due September 30, 2026. Because applicants must use the current DNR application materials, Atlas verified the live DNR page and current form links on September 10, 2026. Applicants should reconfirm the packet immediately before final submission.
