Protecting America's Drinking Water from Extreme Temperatures Act of 2026

Sponsored By: Senator Rosen, Jacky [D-NV]

Introduced

Summary

Adds extreme temperatures as an explicit risk to drinking water resilience planning. This bill would amend the Safe Drinking Water Act to expand the Midsize and Large Drinking Water System Infrastructure Resilience and Sustainability Program so grants and planning explicitly cover extreme temperatures alongside natural hazards and extreme weather. It would also extend the program window to cover 2027 through 2032.

Show full summary
  • Water systems: Midsize and large drinking water systems would be able to seek resilience grants for projects that address heat waves, extreme cold, and related stresses on treatment and distribution. These grants would align project eligibility and risk assessments with temperature extremes.
  • Households and communities: Local water supplies could see more projects aimed at protecting water quality and delivery during extreme temperature events, which may reduce service disruptions.
  • State and local planners: Risk assessments and grant criteria would explicitly include extreme temperatures and keep flooding risks on the list, guiding project selection and planning over the extended 2027–2032 period.

Protect drinking water from heat

This bill would add "extreme temperatures" as a covered risk for the Midsize and Large Drinking Water System Infrastructure Resilience and Sustainability Program. It would amend subsections (b), (c), and (d) so planning, assessment, and projects may address extreme temperatures (the bill notes flooding risks are included). It would replace the program years "2022 through 2026" with "2027 through 2032" to extend the program window. If enacted, midsize and large drinking water systems and eligible state or local utilities would be able to apply for resilience grants that address extreme heat and cold during the extended period. The bill does not set new funding amounts.
