Effective February 2017, the NJ Water Agency Response Network (NJWARN) has been dissolved.

For local emergency incidents, water systems are encouraged to establish and strengthen mutual aid agreements with your neighboring systems or systems of similar size to support potential resource needs.   For large scale events, the local, county, State OEM structure is the established pathway for resource needs.  The OEM process allows for water and wastewater system requests for resources to be elevated from local level to the State OEM.  This process is well supported. Any resource needs outside of State availability can be elevated by the State OEM to the Emergency Management Assistance Compact (EMAC is the nation’s state to state mutual aid system) and/or the Federal Emergency Management Agency (FEMA), as needed. It is important that you familiarize yourself with the local and county OEM coordinators and understand their expectations and procedures for processing your resource needs.  A listing of OEM county coordinators is available at:
