Risk and Resilience Assessment for Community Water Systems

This document is a guide detailing the requirements for Risk and Resilience Assessments (RRA) and Emergency Response Plans (ERP) for community water systems as mandated by America’s Water Infrastructure Act of 2018 (AWIA). It outlines that community water systems serving over 3,300 persons must conduct RRAs that assess risks from both malevolent acts and natural hazards. The document specifies the need for these systems to prepare or revise their ERPs based on RRA findings and to submit certifications of completion to the Environmental Protection Agency (EPA). It describes the primary objectives of an RRA, which include understanding threats and vulnerabilities, informing resource allocation, and enhancing ERP effectiveness. Additionally, the guide explains the RAMCAP methodology used for risk analysis and management, emphasizing the importance of training utility personnel in compliance processes. The document also mentions the proprietary software developed by Trinity to assist in creating comprehensive RRAs efficiently.
