This bill aims to extend the authorization for critical federal programs supporting water infrastructure. Its primary purpose is to ensure continued funding and support for projects that enhance the resilience and sustainability of both clean water and drinking water systems across the nation. Specifically, the legislation amends the Federal Water Pollution Control Act to reauthorize the clean water infrastructure resiliency and sustainability program , extending its funding from fiscal years 2022-2026 to fiscal years 2027 through 2031 . Concurrently, it modifies the Safe Drinking Water Act to reauthorize two distinct drinking water infrastructure resilience and sustainability programs for the same new fiscal year period. These reauthorizations are crucial for enabling communities to protect their water resources and infrastructure against various threats, including climate change impacts and other disruptions.
