## 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. - 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.
