In today’s evolving landscape of environmental and security threats, safeguarding public water systems is more critical than ever. Under the America’s Water Infrastructure Act Section 2013 (AWIA), the EPA mandates that all community water systems serving more than 3,300 people must complete a Risk and Resilience Assessment (RRA) and develop a corresponding Emergency Response Plan (ERP). These requirements are designed to help utilities prepare for and respond to both natural hazards and malevolent acts.
