Water System Emergency Planning/Security

In order to maintain a water system that is protected and secure, it is important to assess potential risks to the system and take action to improve emergency response. To help public water suppliers maintain a high level of protection and security, DWGB works to provide systems with the training and tools necessary to help systems assess vulnerabilities and improve emergency response and security.

If a community system or non-community non-transient system experiences an emergency or security breach or other impairment, they are required to notify NHDES DWGB within 24 hours. (Rule cited: Env-Dw 503.02 Notice of Impairment.)
