StoryMap of Project Profiles

We're advertising our successful projects in a new, more engaging way—through 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.

    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, your contracts manager will contact you for your project scope of work negotiation.

    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.
