The Water Project Navigators Act creates a new federal program to help communities develop water projects that address multiple challenges at once—like drought, flooding, water quality, and ecosystem health. Here's what it does: The Secretary of the Interior will establish the Water Project Navigators Program, which provides grants and cooperative agreements to eligible organizations (states, tribes, local governments, water districts, and nonprofits) to hire or support "navigators." These navigators are essentially project specialists who help communities plan and build water projects by providing grant writing assistance, project management, technical expertise, and other support. The program prioritizes funding for Indian tribes, disadvantaged communities, rural areas, and organizations with limited resources. The projects themselves must provide multiple benefits—they could improve water efficiency, increase water recycling, protect drinking water supplies, restore ecosystems, create jobs, or improve recreational opportunities. The federal government will cover up to 75% of project costs, though this requirement can be reduced or waived for tribes and disadvantaged communities facing financial hardship. The program is designed to help communities that have identified water projects they need but lack the capacity or expertise to develop them on their own.
