A mutual aid and assistance network provides water and wastewater utilities with the means to quickly obtain help in the form of personnel, equipment, materials and associated services from other utilities to restore critical operations impacted during any type of emergency, big or small.

Becoming a member of a mutual aid and assistance network before an emergency occurs can make all the difference when your community’s water or wastewater system needs help. Use the resources below to ensure you have an effective support system in place.

Learn about WARN

Water and Wastewater Agency Response Networks (WARNs) are comprised of "utilities helping utilities" within a state that respond to and recover from emergencies by sharing resources with one another. WARNs are governed by a common mutual aid agreement. The WARN agreement allows utilities to share resources in a more expedited way, compared to other mechanisms that require a formal disaster declaration. The agreement spells out how liability, workers’ compensation, insurance and reimbursement will work. Other benefits include increased emergency preparedness and coordination, and enhanced access to specialized resources. Utility responders, once notified, are typically on the ground within 24 hours.

See the types of responses WARNs can be used for in the video below.

Join a WARN

WARNs are built on a strong base of utility members. All types of water utilities – drinking water, wastewater, public, private, large and small – can benefit from joining their state WARN.

WARNs exist in 49 of the 50 states, as well as the National Capital Region. Follow the links in the table below for more information on how to join your state’s WARN.
