This legislation, known as the Water Infrastructure Resilience and Sustainability Act, aims to extend the authorization for critical federal programs focused on enhancing water infrastructure resilience and sustainability. It achieves this by amending both the Federal Water Pollution Control Act and the Safe Drinking Water Act. The bill specifically reauthorizes the Clean Water Infrastructure Resiliency and Sustainability Program , the Drinking Water System Infrastructure Resilience and Sustainability Program , and the Midsize and Large Drinking Water System Infrastructure Resilience and Sustainability Program . For each of these programs, the authorization is extended from its current expiration in fiscal year 2026 to fiscal year 2031, ensuring continued federal support for these vital initiatives.
