Water ISAC Threat Protection Act

This bill sets up a program at the Environmental Protection Agency (EPA) to help drinking water and wastewater systems get ready for cyberattacks, physical threats, and natural disasters. Within one year of the law taking effect, the EPA must create the program to support local water utilities in joining and using the Water Information Sharing and Analysis Center (WaterISAC). The program can help pay membership costs, improve sharing of incident data, and strengthen tools that track what’s happening in the water sector and help systems prepare, respond, and recover from threats and hazards.

It also authorizes $10 million each year for fiscal years 2026 and 2027 to run this program.

• Who is affected: Community water systems, publicly owned treatment works (wastewater utilities), the EPA, and WaterISAC.
• What changes: Encourages and subsidizes WaterISAC membership; boosts data sharing and analysis of water-sector threats; strengthens tools and resources for monitoring and preparedness, including responding to and recovering from malevolent acts and natural hazards.
• When: EPA must start the program within one year of enactment; funding is available in fiscal years 2026 and 2027.
