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

This bill proposes to amend the Safe Drinking Water Act, specifically targeting the Midsize and Large Drinking Water System Infrastructure Resilience and Sustainability Program. The primary goal is to broaden the scope of this federal grant program to better protect public drinking water supplies. The legislation achieves this by explicitly including extreme temperatures as a factor for which grant funds can be used to enhance infrastructure resilience. This means that drinking water systems can now apply for and utilize federal assistance to mitigate risks and adapt their infrastructure to withstand the impacts of both hot and cold temperature extremes. By integrating extreme temperatures into the program's criteria, the bill enables water utilities to proactively address vulnerabilities and ensure the continuous, safe delivery of drinking water. Furthermore, it extends the authorization for appropriations for this program from fiscal years 2022-2026 to 2027-2032 , ensuring continued funding for these critical resilience efforts.
