Regulatory Updates

AWIA Section 2013: Risk and Resilience Assessments

The America’s Water Infrastructure Act (AWIA), signed into law on October 23, 2018, amended Section 1433 of the Safe Drinking Water Act (SDWA) to require community water systems (CWSs) serving more than 3,300 people to develop or update Risk and Resilience Assessments (RRAs) and Emergency Response Plans (ERPs). 

These assessments help utilities evaluate their vulnerabilities to both natural hazards and malevolent acts and strengthen the resilience of critical water infrastructure. AWIA also establishes recurring deadlines by which systems must certify to the U.S. Environmental Protection Agency (EPA) the completion of these plans. 

Deadlines 

Community water systems are required to review and recertify their RRA and ERP every five years. The next deadlines are based on population served:

*ERP certifications are due six months from the date of the RRA certification. The dates shown above are certification dates based on a utility submitting an RRA on the final due date. 

What the Assessments Must Include 

For RRA assessments, each CWS serving a population of over 3,300 will need to assess the risks and resilience of its system. Assessments will include:  

  1. The risk to the system from malevolent acts and natural hazards 
  2. Resilience of the pipes and constructed conveyances, physical barriers, source water, water collection and intake, pretreatment, treatment, storage and distribution facilities, electronic, computer or other automated systems that are utilized by the system 
  3. Monitoring practices 
  4. System financial infrastructure  
  5. Chemical use, storage and handling  
  6. System operation and maintenance 

Following RRA certification, each system must prepare or revise, if necessary, an ERP that incorporates the RRA findings. This includes: 

  1. Strategies and resources to improve the resilience of the system's physical security and the cybersecurity 
  2. Plans, procedures and equipment to implement in case of a emergencies that threatens the ability to deliver safe drinking water 
  3. Actions, procedures and equipment that can prevent or significantly reduce the impact of a malevolent act or natural hazard on the public health and safety of the public drinking water supply. This includes the development of alternative source water options, relocation of water intakes and construction of flood protection barriers 
  4. Strategies to aid in the detection of malevolent acts or natural hazards that threaten the security or resilience of the system
