US EPA data reflect that the following is a list of all wholesale community water systems (CWS), those that sell or provide water to other CWSs, required to certify completion of a risk and resilience assessment (by June 30, 2021) and an emergency response plan (by December 31, 2021) under Section 2013 of America's Water Infrastructure Act (AWIA). EPA uses the population served number that each CWS reported to its respective primacy agency for the Safe Drinking Water Information System (SDWIS) database as of the date of AWIA’s enactment on October 23, 2018. This list was generated on February 25, 2021. EPA will continue to verify the wholesale CWSs that belong on this list. Data will be updated for accuracy on an ongoing basis.
