Water System Threat Preparedness and Resilience Act of 2023

S 660, the Water System Threat Preparedness and Resilience Act of 2023, establishes a program to enhance water system security. It requires the EPA to support community water systems and publicly owned treatment works (like municipal water and wastewater facilities) in joining the Water Information Sharing and Analysis Center. Key mechanisms include offsetting membership costs, improving EPA coordination for threat data sharing, and providing enhanced tools to monitor threats (including natural disasters and intentional acts) and prepare for incidents. The program is funded with $10 million annually for 2024-2025.
