Mutual Aid

National efforts established statewide Water and Wastewater Agency Response Network (WARN) systems that create a formalized system of utilities helping utilities during emergencies or disasters. There are 50 WARNs in the U.S. and 2 Canadian WARNs. New Hampshire already has its own mutual aid network that was developed in 1998 and currently has over 162 members. The NH Public Works Mutual Aid Program (NHPWMA) is coordinated by the UNH Technology Transfer Center. The program was used most recently during the August 2008 tornado and floods of 2005-2007 . Water systems are urged to participate in this important program. More information can be found on the program Web site at or For information on other state WARN programs check out the American Water Works Association national website.
