Water Resilience

Electronic Certification Process for Completion of Risk and Resilience Assessments and Emergency Response Plans

This document provides guidance on how to certify the completion of your community water system’s risk and resilience assessment and emergency response plan to the U.S. EPA, as required under Section 2013 of America's Water Infrastructure Act. This law establishes certification deadlines based on community water system population served and requires re-certification to occur every five-years; see U.S. EPA’s America’s Water Infrastructure Act website for more information. For purposes of this guide, we will illustrate the path of a utility certifying its risk and resilience assessment first, then its emergency response plan.
