America’s Water Infrastructure Act (AWIA) Section 2013 requires community (drinking) water systems (CWSs) serving more than 3,300 people to develop or update risk and resilience assessments (RRAs) and emergency response plans (ERPs) every five years.
During the first 5-year certification period, approximately 98% of CWSs serving more than 3,300 people certified to EPA that they completed an RRA and ERP, as required by AWIA Section 2013. Thank you to the CWSs, technical assistance providers, and water sector organizations that helped CWSs comply with the law and improve their preparedness for malevolent acts and natural hazards!
