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.

Wisconsin provided over $7.3 billion in financial assistance to municipalities since State Fiscal Year 1991 through the Environmental Improvement Fund (EIF) programs. View the financial assistance summary and annual reports.

The Clean Water Fund Program (CWFP) and the Safe Drinking Water Loan Program (SDWLP) provide affordable financial assistance to communities within Wisconsin for eligible water infrastructure projects that protect and improve public health and water quality for current and future generations. Eligible projects include those that are needed to achieve or maintain compliance with federal and state regulations relating to wastewater treatment and drinking water supply.

Highlights

  • Online application system.
  • Fixed interest rate on 20-year loan term.
  • Program subsidy buys down market rate on program loan.
  • Standard interest rate is 55% of market rate.
  • Coordination with other funding sources.
  • Dedicated DNR loan project manager and construction management engineer.

The Clean Water Fund Program and the Safe Drinking Water Loan Program can finance construction as it takes place, refinance interim debt used to design and construct a project and reimburse internal funds a municipality temporarily used to pay for project costs before receiving its subsidized (low interest) loan through the CWFP or the SDWLP. In recent years, additional subsidization of program loans in the form of principal forgiveness (PF) has been available to economically disadvantaged municipalities.

INTENDED USE PLAN

To learn how funds will be allocated to eligible projects of applicants (municipalities), read the program's intended use plan (IUP) for the corresponding state fiscal year funding cycle. The DNR produces an annual funding policy for each the CWFP and the SDWLP in the form of an IUP that describe methods for making funding determinations and other program policies related to the fiscal year. The IUP is not all encompassing, it is meant to be used in conjunction with the governing laws. For each program, there is specific project eligibility criteria, a scoring and ranking system, and specific deadlines. The program implementation details are established in the applicable governing statutes and administrative codes.

Clean Water Fund Program

The Clean Water Fund Program (CWFP) provides subsidized loans to municipalities for publicly owned wastewater treatment and collection system infrastructure projects. It includes projects for compliance with a municipality's Wisconsin Pollution Discharge Elimination System (WPDES) permit.

Safe Drinking Water Loan Program

The Safe Drinking Water Loan Program (SDWLP) provides subsidized loans to municipalities for public drinking water system and infrastructure projects.

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. View a list of water and wastewater funding and technical assistance sources.

Eligible CWFP Applicants

Eligible Projects and Costs

The following are general guidelines helpful in determining whether a CWFP or a SDWLP 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 correcting 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.
Eligible Projects

Eligible projects include those that are needed to achieve or maintain compliance with federal and state regulations relating to wastewater treatment (i.e. Clean Water Act) and drinking water supply (i.e. Safe Drinking Water Act). The CWFP includes projects for compliance with a municipality's Wisconsin Pollution Discharge Elimination System (WPDES) permit.

Eligible Costs

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 (e.g. collection, conveyance, disposal, distribution, sourcing, storage, transmission and treatment).

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 a regional DNR engineer.

     
  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 a CWFP or a SDWLP loan.

    When your project score is finalized by the DNR, you will receive an email notification. Eligible projects will be placed on the corresponding program's Project Priority List 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 CWFP or the SDWLP.

     
  3. Application - Once your project is on the Project Priority List, you may apply for funding for that state fiscal year. A financial assistance application must be submitted online for each project for which you will be seeking a CWFP or SDWLP loan.

    Note: The Pilot Projects CWFP Financial Assistance Application (Form 8700-378) is currently not available to submit via the online system.

The applicable deadlines are set in the corresponding program's annual intended use plan for the upcoming fiscal years. The state fiscal year (SFY) runs from July 1 of one calendar year through June 30 of the next and is designated by the calendar year in which it ends.

Application Deadlines

  • Oct. 31 – CWFP and SDWLP notice of Intent to Apply submittal deadline for the following SFY funding cycle (includes Priority Evaluation and Ranking Formula).
  • June 30 – SDWLP application submittal deadline if competing for principal forgiveness for the upcoming SFY funding cycle.
  • Sept. 30 – CWFP application submittal deadline if competing for principal forgiveness for the current SFY funding cycle.

Applications may be submitted at any time during the state fiscal year; however, a complete application must be submitted by the deadline to be ranked on the corresponding program's Funding List in priority score order for the purpose of allocating loan funds and principal forgiveness. Complete, eligible applications received after the submittal deadline will be eligible for loan funding, if available, and will not be eligible for general principal forgiveness (PF). The CWFP applications submitted after Sept. 30 may still receive a loan and be considered for Energy Efficiency Priority PF if funding is available.

Note: When a deadline falls on a weekend or legal holiday, that deadline is extended to the next business day, per s. 990.001(4), Wis. Stats.

Loan Closing Deadlines

The assigned DNR loan project manager will work with the municipality to establish a loan closing date as well as a timeline for submitting the required documentation needed to prepare the Financial Assistance Agreement (FAA), also known as a loan. The loan closing date is normally scheduled for the second or fourth Wednesday of the month.

  • Sept. 30 – SDWLP loan closing deadline for prior year's allocations. Sign the FAA (loan) by the Sept. 30 of the year following the SDWLP application submittal deadline.
  • For both principal forgiveness and non-PF CWFP projects, the loan must close within eight months following the date of the application acceptance notification.
    • All PF CWFP applications are accepted by June 30 (the end of the state fiscal year).
    • Non-PF CWFP applications are accepted by the Dec. 31 of the following state fiscal year.

Deadline Guidance

The "Deadlines During State Fiscal Year" publication is a visual aid that was created to emphasize the application process and loan closing timelines.
