What is ILWARN?

ILWARN is a utility-to-utility network that helps member water and wastewater utilities recover from disasters by getting resources – personnel and equipment – when and where they are needed.  ILWARN is available to all public and private water and wastewater utilities in Illinois.  There is no cost to become a member, however a standard mutual aid agreement must be signed before requesting assistance.

Through the ILWARN web site (, a member can request emergency equipment (pumps, generators, chlorinators, evacuators, etc.) and trained personnel (such as treatment plant operators) that they might need in an emergency.  There is no obligation to respond to an emergency.  Utilities respond at their choice if they can, for as long as they can.



Becoming a Member

The ILWARN site contains several documents that describe and explain the process of joining this mutual aid and assistance network.  Other helpful resources are and EPA Water: Mutual Aid and Assistance.  Both pages have useful documents that can assist you in making the decision to support your utility by becoming an ILWARN member.

Illinois Section AWWA – Steering Committee

ILWARN is supported through the cooperation of the water and wastewater organizations in Illinois and by several state and federal agencies, including ISAWWA.  A steering committee made up of utility members from across the state helps plan and coordinate emergency planning and response activities for ILWARN.  If you are interested in joining the steering committee please contact the Chair of the committee listed below or e-mail
