What it does
This bill extends and expands federal desalination programs under existing water law. It reauthorizes the Department of Interior's ability to fund desalination projects in western states (Reclamation States) for up to 15 years, increases the federal cost-share cap from an unspecified amount to 25% of project costs with no dollar ceiling, and creates a new competitive grant program for advanced desalination pilot projects and technology research, including brine management.
Why we flagged it
The bill's operative mechanism is federal cost-sharing and grant funding for desalination projects and research. While framed as reauthorization of existing programs, it materially expands federal financial exposure by removing dollar caps and establishing new competitive grant authority.
What the text implies
- Removal of any dollar cap on federal participation means the federal government could fund 25% of arbitrarily large desalination projects with no statutory spending limit, creating open-ended appropriations exposure.
- The bill defines 'eligible desalination project' to include projects where 'primary water supply benefit accrues to' entities in Reclamation States — a broad definition that may capture projects serving private irrigation districts or municipal water agencies rather than the general public.
