Drinking Water State Revolving Fund (DWSRF)

Lead Service Line Loan

This funding program is open for applications April 1 to April 28, 2023. Eligible projects include lead service line inventories and lead service line replacements. See the following documents for more information. We recently passed two emergency rules to help conform to the Bipartisan Infrastructure Law (BIL) requirements. We filed the first rule during the construction loan application review; it allowed the department to grant 100 percent loan forgiveness to qualified applicants. We filed the second rule when the lead service line loan guidelines were published. This allows us to modernize the definition of disadvantaged community and update or remove obsolete water system requirements. For more information about these rulemakings, please visit our Rulemaking webpage.

The Drinking Water State Revolving Fund (DWSRF) makes funds available to drinking water systems to pay for infrastructure improvements. This program is funded through federal and state money and subject to state laws and additional federal regulations.

The program provides:

  • Low-interest construction loans to publicly- (municipal) and privately-owned drinking water systems. These loans cover capital improvements that increase public health and compliance with drinking water regulations.
  • Loan repayments can range from 20 to 30 years. In some cases, partial loan forgiveness is offered.
  • Consolidation Feasibility Study grants.

After You Are Approved for a Loan

Environmental review and cultural review

All federally funded infrastructure projects must undergo both an environmental and a cultural review. These identify and analyze potential impacts a project might have on environmental, historical, and cultural resources.


If your project is funded, refer to the DWSRF Customer Loan Handbook 331-586 (PDF) for your next steps. Here's a Loan Payment Calculator for your use.

StoryMap of Project Profiles

We advertise our successful projects in a new, more engaging way with a StoryMap. This is a data-driven way to talk about a project and provides a map tour and synopsis of successful DWSRF projects around the state. Each point on the map links to a description and photo, with a link to more details. We hope this new way to communicate our successes inspires other drinking water systems to participate in our program and gives them new ideas for solving challenges they may face.
