Relating to the reporting of certain security incidents by public water systems to the Texas Commission on Environmental Quality and the Department of Information Resources.

SB 1625 requires public water supply and wastewater systems in Texas to immediately report specific security incidents to the Texas Commission on Environmental Quality (TCEQ) and the Department of Information Resources. It mandates reporting for events like unauthorized access attempts, ransomware attacks, terrorism threats, or system disruptions that could impact water safety. Key examples include cyber intrusions targeting operational systems, theft of critical equipment, or natural disasters causing service outages. This directly affects all public water and wastewater providers across the state, including small nonindustrial systems. The bill clarifies reporting obligations without specifying enforcement actions or penalties.
