Mutual Aid and Assistance for Drinking Water and Wastewater Utilities

On this page:

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 an emergency.

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