Environmental Loans

Clean Water Fund Program and Safe Drinking Water Loan Program

Loan Capacity Update

Due to continued high demand for financial assistance, loan capacity limitations may impact State Fiscal Year 2025 CWFP and SDWLP applications. For more information, go to our Loan Capacity webpage.

The purpose of the Environmental Loans Section is to administer affordable financial assistance to communities within Wisconsin for water infrastructure projects that protect and improve public health and water quality for current and future generations. Wisconsin provided over $7.3 billion in financial assistance to municipalities since State Fiscal Year 1991 through two Environmental Improvement Fund (EIF) programs.

Under the Clean Water Fund Program (CWFP) and the Safe Drinking Water Loan Program (SDWLP), municipalities may receive financial assistance in the form of subsidized loans and additional subsidy to reduce the size of a loan. The programs can finance construction as it takes place, refinance interim debt used to design and construct a project and reimburse municipal funds used for project costs.

Benefits and program features:

  • Program subsidy buys down the market rate on loans (reduced-interest rate loans).
  • Some municipalities may be eligible for further subsidy to reduce their loan size (principal forgiveness).
  • Fixed interest rates on long-term loans (up to 30 years).
  • Coordination of funds with other funding sources.
  • Online submittal system for Intents to Apply and Financial Assistance Applications.
  • Dedicated DNR loan project manager and construction management engineer.

Funding programs

Clean Water Fund Program

The Clean Water Fund Program (CWFP) provides financial assistance to municipalities for wastewater and storm water infrastructure projects. It includes projects for compliance with a municipality's WPDES permit.

Pilot Projects Program

Pilot Projects Program provides a subsidy to municipalities seeking to fund water quality trading projects and other non-traditional projects (i.e., projects not related to a wastewater treatment plant upgrade) for compliance with a municipality's WPDES permit.

Safe Drinking Water Loan Program

The Safe Drinking Water Loan Program (SDWLP) provides financial assistance to municipalities for drinking water infrastructure projects.

Lead Service Line Projects

Funding options for lead service line (LSL) replacements.

Other funding sources

The Wisconsin DNR Environmental Loans Section often partners with other funding agencies to ensure that municipalities get the best funding package to meet their needs. The DNR and other funding sources can collaborate to clarify the joint funding process and help with common paperwork challenges.

Eligibility

Who may apply?

Eligible applicants include Wisconsin cities, towns, villages, counties, sanitary districts and other qualifying municipalities.

How may funds be used?

The program funds are for reasonable and necessary costs directly related to the planning, design and construction of eligible projects. Funds may be used to construct, improve, modify, purchase, replace, restore and upgrade drinking water, wastewater and storm water systems and infrastructure; such as collection, conveyance, disposal, distribution, sourcing, storage, transmission and treatment. For more information, read:

The following are general guidelines helpful in determining whether an EIF loan would be appropriate for your project.

  • The municipal wastewater project is a necessity to stay in compliance with WPDES permits or to meet new permit requirements.
  • Projects constructing a new sewer system to eliminate groundwater pollution and threats to public health.
  • Projects that correct public water systems that violate health standards, have contamination, are not in compliance with drinking water standards or have inadequate transmission pipes and/or storage facilities.

How to Apply

How do we apply?

Follow these steps in order to apply for funding:

  1. Identify and define the wastewater treatment or drinking water "problem" that needs to be corrected or prevented. This process generally involves a joint effort of the municipality, a consulting engineer, and the DNR engineer in your area.
     
  2. Pre-Application - A notice of Intent to Apply (ITA) and Priority Evaluation & Ranking Formula (PERF) must be submitted online for each project for which you will be seeking an EIF loan. The deadline for all ITAs/PERFs is October 31 for the following state fiscal year (SFY) funding cycle. For example, if you wish to apply for SFY 2026 funding (July 1, 2025 through June 30, 2026), the ITA/PERF deadline is October 31, 2024.

    When your project score is finalized by the DNR, you will receive an email notification. Eligible projects will be placed on the Project Priority List (PPL) in priority score order.

    ITAs/PERFs are only valid for one state fiscal year. If you do not go forward with submitting an application, be sure to re-submit an ITA/PERF for the following state fiscal year, if you are still pursuing funding from the EIF.
     

  3. Application - Once your project is on the Project Priority List (PPL), you may apply for funding for that state fiscal year. Refer to the documents below for more information on the application.
