RRA & ERP Compliance for Systems Serving More Than 3,300 People

As compliance deadlines approach, now is a great time to review America's Water Infrastructure Act (AWIA) section 2013 to ensure your system is on track. AWIA requires all community water systems serving more than 3,300 people to complete a certified Risk and Resilience Assessment (RRA) and update their Emergency Response Plan (ERP) within the established five‑year cycle. To assist with this, U.S. EPA continues to offer tools, templates, and technical assistance to help systems strengthen physical security, cybersecurity, and overall resilience.

Below is a reminder of the upcoming deadlines to help you stay in compliance and plan ahead:

Risk and Resilience Assessments (RRA)

• Due by June 30, 2026

Emergency Response Plans (ERP)

• Due six months after your RRA submission

If you have already submitted or certified completion of your plans, no further action is needed at this time.

NOTE: Systems that serve less than 3,301 people are not required to certify the completion of these plans to U.S. EPA but are encouraged to conduct RRAs and ERPs in order to prepare for potential risks or emergencies.
