Security and Emergency Preparedness


Emergency Response Plan (ERP) Templates


All public water systems in Maine should prepare and implement or update existing emergency and security plans to include foreseeable and unforeseeable disturbances relating to production and supply of safe drinking water.

Emergency situations include, but are not limited to the following situations:

  • A failure or significant interruption in the production of drinking water
  • A natural disaster that disrupts the water supply
  • A chemical spill or biological substance introduced into the water source, that increases the potential for contamination
  • The failure of cross connections
  • Intentional physical intrusions of the water system
  • Any other activity that disturbs the production and supply of safe drinking water

All public water systems serving more than 3,300 persons are required by the Public Health Security and Bioterrorism Response Act of 2002 to complete Vulnerability Assessments and develop or revise Emergency Response Plans. All public water systems included in this requirement must make the Emergency Response Plans available for inspection by Drinking Water Program staff upon request.

Emergency Response Plans must include, but not by way of limitation, the following information to be utilized in the event of a terrorist or other intentional act perpetrated against the public water system:

  • Actions, plans, procedures and equipment to be utilized to lessen the impact of the intentional act
  • Emergency contact information
  • Any other information deemed necessary to deal with the emergency

Security Breaches and Emergency Notification Requirements

  • All public water systems reporting security breaches, tampering events or other emergencies affecting water system components to law enforcement must report the incidents to the Drinking Water Program
  • All Public Utilities Commission (PUC)-regulated water systems reporting security-related incidents to law enforcement agencies must report such incidents to both the Drinking Water Program and the PUC
  • All public water systems experiencing emergency events involving biological or chemical contamination of water system components must report said events to the Drinking Water Program
