I am thrilled to announce that our next One Water Summit will be in Pittsburgh, Pennsylvania, July 8 – 11, 2025! We’re looking forward to holding our signature event in a city that has served as a national model for centering water equity, advocating for sustainable water policies, removing lead service lines, and driving large-scale water infrastructure projects.

One Water Summit is the nation’s premier gathering of cross-sector water trailblazers, experts, and enthusiasts. Since 2016, One Water Summit has sparked innovation by creating unique spaces for collaboration—centered around timely water challenges and solutions. To illustrate the power of this event and our collective One Water community, I’m also pleased to share the One Water Summit 2023 Commitments to Action made by the incredible group of delegates who attended last year’s Summit in Tucson. For questions regarding 2025 Summit delegations, please email

Yours in One Water,
